-# go-whatsapp
-Package rhymen/go-whatsapp implements the WhatsApp Web API to provide a clean interface for developers. Big thanks to all contributors of the [sigalor/whatsapp-web-reveng](https://github.com/sigalor/whatsapp-web-reveng) project. The official WhatsApp Business API was released in August 2018. You can check it out [here](https://www.whatsapp.com/business/api).
-
-## Installation
-```sh
-go get github.com/rhymen/go-whatsapp
-```
-
-## Usage
-### Creating a connection
-```go
-import (
-    whatsapp "github.com/Rhymen/go-whatsapp"
-)
-
-wac, err := whatsapp.NewConn(20 * time.Second)
-```
-The duration passed to the NewConn function is used to timeout login requests. If you have a bad internet connection use a higher timeout value. This function only creates a websocket connection, it does not handle authentication.
-
-### Login
-```go
-qrChan := make(chan string)
-go func() {
-    fmt.Printf("qr code: %v\n", <-qrChan)
-    //show qr code or save it somewhere to scan
-}
-sess, err := wac.Login(qrChan)
-```
-The authentication process requires you to scan the qr code, that is send through the channel, with the device you are using whatsapp on. The session struct that is returned can be saved and used to restore the login without scanning the qr code again. The qr code has a ttl of 20 seconds and the login function throws a timeout err if the time has passed or any other request fails.
-
-### Restore
-```go
-newSess, err := wac.RestoreSession(sess)
-```
-The restore function needs a valid session and returns the new session that was created.
-
-### Add message handlers
-```go
-type myHandler struct{}
-
-func (myHandler) HandleError(err error) {
-	fmt.Fprintf(os.Stderr, "%v", err)
-}
-
-func (myHandler) HandleTextMessage(message whatsapp.TextMessage) {
-	fmt.Println(message)
-}
-
-func (myHandler) HandleImageMessage(message whatsapp.ImageMessage) {
-	fmt.Println(message)
-}
-
-func (myHandler) HandleVideoMessage(message whatsapp.VideoMessage) {
-	fmt.Println(message)
-}
-
-func (myHandler) HandleJsonMessage(message string) {
-	fmt.Println(message)
-}
-
-wac.AddHandler(myHandler{})
-```
-The message handlers are all optional, you don't need to implement anything but the error handler to implement the interface. The ImageMessage and VideoMessage provide a Download function to get the media data.
-
-### Sending text messages
-```go
-text := whatsapp.TextMessage{
-    Info: whatsapp.MessageInfo{
-        RemoteJid: "0123456789@s.whatsapp.net",
-    },
-    Text: "Hello Whatsapp",
-}
-
-err := wac.Send(text)
-```
-The message will be send over the websocket. The attributes seen above are the required ones. All other relevant attributes (id, timestamp, fromMe, status) are set if they are missing in the struct. For the time being we only support text messages, but other types are planned for the near future.

-## Examples
-
-### Standard colors
-
-```go
-// Print with default helper functions
-color.Cyan("Prints text in cyan.")
-
-// A newline will be appended automatically
-color.Blue("Prints %s in blue.", "text")
-
-// These are using the default foreground colors
-color.Red("We have red")
-color.Magenta("And many others ..")
-
-```
-
-### Mix and reuse colors
-
-```go
-// Create a new color object
-c := color.New(color.FgCyan).Add(color.Underline)
-c.Println("Prints cyan text with an underline.")
-
-// Or just add them to New()
-d := color.New(color.FgCyan, color.Bold)
-d.Printf("This prints bold cyan %s\n", "too!.")
-
-// Mix up foreground and background colors, create new mixes!
-red := color.New(color.FgRed)
-
-boldRed := red.Add(color.Bold)
-boldRed.Println("This will print text in bold red.")
-
-whiteBackground := red.Add(color.BgWhite)
-whiteBackground.Println("Red text with white background.")
-```
-
-### Use your own output (io.Writer)
-
-```go
-// Use your own io.Writer output
-color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-blue := color.New(color.FgBlue)
-blue.Fprint(writer, "This will print text in blue.")
-```
-
-### Custom print functions (PrintFunc)
-
-```go
-// Create a custom print function for convenience
-red := color.New(color.FgRed).PrintfFunc()
-red("Warning")
-red("Error: %s", err)
-
-// Mix up multiple attributes
-notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-notice("Don't forget this...")
-```
-
-### Custom fprint functions (FprintFunc)
-
-```go
-blue := color.New(FgBlue).FprintfFunc()
-blue(myWriter, "important notice: %s", stars)
-
-// Mix up with multiple attributes
-success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-success(myWriter, "Don't forget this...")
-```
-
-### Insert into noncolor strings (SprintFunc)
-
-```go
-// Create SprintXxx functions to mix strings with other non-colorized strings:
-yellow := color.New(color.FgYellow).SprintFunc()
-red := color.New(color.FgRed).SprintFunc()
-fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
-fmt.Printf("This %s rocks!\n", info("package"))
-
-// Use helper functions
-fmt.Println("This", color.RedString("warning"), "should be not neglected.")
-fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
-
-// Windows supported too! Just don't forget to change the output to color.Output
-fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-```
-
-### Plug into existing code
-
-```go
-// Use handy standard colors
-color.Set(color.FgYellow)
-
-fmt.Println("Existing text will now be in yellow")
-fmt.Printf("This one %s\n", "too")
-
-color.Unset() // Don't forget to unset
-
-// You can mix up parameters
-color.Set(color.FgMagenta, color.Bold)
-defer color.Unset() // Use it in your function
-
-fmt.Println("All text will now be bold magenta.")
-```
-
-### Disable/Enable color
- 
-There might be a case where you want to explicitly disable/enable color output. the 
-`go-isatty` package will automatically disable color output for non-tty output streams 
-(for example if the output were piped directly to `less`)
-
-`Color` has support to disable/enable colors both globally and for single color 
-definitions. For example suppose you have a CLI app and a `--no-color` bool flag. You 
-can easily disable the color output with:
-
-```go
-
-var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-if *flagNoColor {
-	color.NoColor = true // disables colorized output
-}
-```
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-```go
-c := color.New(color.FgCyan)
-c.Println("Prints cyan text")
-
-c.DisableColor()
-c.Println("This is printed without any color")
-
-c.EnableColor()
-c.Println("This prints again cyan...")
-```

-    color.Cyan("Prints text in cyan.")
-
-    // a newline will be appended automatically
-    color.Blue("Prints %s in blue.", "text")
-
-    // More default foreground colors..
-    color.Red("We have red")
-    color.Yellow("Yellow color too!")
-    color.Magenta("And many others ..")
-
-    // Hi-intensity colors
-    color.HiGreen("Bright green color.")
-    color.HiBlack("Bright black means gray..")
-    color.HiWhite("Shiny white color!")
-
-However there are times where custom color mixes are required. Below are some
-examples to create custom color objects and use the print functions of each
-separate color object.
-
-    // Create a new color object
-    c := color.New(color.FgCyan).Add(color.Underline)
-    c.Println("Prints cyan text with an underline.")
-
-    // Or just add them to New()
-    d := color.New(color.FgCyan, color.Bold)
-    d.Printf("This prints bold cyan %s\n", "too!.")
-
-
-    // Mix up foreground and background colors, create new mixes!
-    red := color.New(color.FgRed)
-
-    boldRed := red.Add(color.Bold)
-    boldRed.Println("This will print text in bold red.")
-
-    whiteBackground := red.Add(color.BgWhite)
-    whiteBackground.Println("Red text with White background.")
-
-    // Use your own io.Writer output
-    color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-    blue := color.New(color.FgBlue)
-    blue.Fprint(myWriter, "This will print text in blue.")
-
-You can create PrintXxx functions to simplify even more:
-
-    // Create a custom print function for convenient
-    red := color.New(color.FgRed).PrintfFunc()
-    red("warning")
-    red("error: %s", err)
-
-    // Mix up multiple attributes
-    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-    notice("don't forget this...")
-
-You can also FprintXxx functions to pass your own io.Writer:
-
-    blue := color.New(FgBlue).FprintfFunc()
-    blue(myWriter, "important notice: %s", stars)
-
-    // Mix up with multiple attributes
-    success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-    success(myWriter, don't forget this...")
-
-
-Or create SprintXxx functions to mix strings with other non-colorized strings:
-
-    yellow := New(FgYellow).SprintFunc()
-    red := New(FgRed).SprintFunc()
-
-    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Printf("this %s rocks!\n", info("package"))
-
-Windows support is enabled by default. All Print functions work as intended.
-However only for color.SprintXXX functions, user should use fmt.FprintXXX and
-set the output to color.Output:
-
-    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
-
-Using with existing code is possible. Just use the Set() method to set the
-standard output to the given parameters. That way a rewrite of an existing
-code is not required.
-
-    // Use handy standard colors.
-    color.Set(color.FgYellow)
-
-    fmt.Println("Existing text will be now in Yellow")
-    fmt.Printf("This one %s\n", "too")
-
-    color.Unset() // don't forget to unset
-
-    // You can mix up parameters
-    color.Set(color.FgMagenta, color.Bold)
-    defer color.Unset() // use it in your function
-
-    fmt.Println("All text will be now bold magenta.")
-
-There might be a case where you want to disable color output (for example to
-pipe the standard output of your app to somewhere else). `Color` has support to
-disable colors both globally and for single color definition. For example
-suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
-the color output with:
-
-    var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-    if *flagNoColor {
-    	color.NoColor = true // disables colorized output
-    }
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-     c := color.New(color.FgCyan)
-     c.Println("Prints cyan text")
-
-     c.DisableColor()
-     c.Println("This is printed without any color")
-
-     c.EnableColor()
-     c.Println("This prints again cyan...")

-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.
-
-Equality is defined in this way:
-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map
-    fields are equal.
-  - Every other combination of things are not equal.
-
-The return value is undefined if a and b are not protocol buffers.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;

-Package context stores values shared during a request lifetime.
-
-Note: gorilla/context, having been born well before `context.Context` existed,
-does not play well > with the shallow copying of the request that
-[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
-(added to net/http Go 1.7 onwards) performs. You should either use *just*
-gorilla/context, or moving forward, the new `http.Request.Context()`.
-
-For example, a router can set variables extracted from the URL and later
-application handlers can access those values, or it can be used to store
-sessions values to be saved at the end of a request. There are several
-others common uses.
-
-The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
-
-	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
-
-Here's the basic usage: first define the keys that you will need. The key
-type is interface{} so a key can be of any type that supports equality.
-Here we define a key using a custom int type to avoid name collisions:
-
-	package foo
-
-	import (
-		"github.com/gorilla/context"
-	)
-
-	type key int
-
-	const MyKey key = 0
-
-Then set a variable. Variables are bound to an http.Request object, so you
-need a request instance to set a value:
-
-	context.Set(r, MyKey, "bar")
-
-The application can later access the variable using the same key you provided:
-
-	func MyHandler(w http.ResponseWriter, r *http.Request) {
-		// val is "bar".
-		val := context.Get(r, foo.MyKey)
-
-		// returns ("bar", true)
-		val, ok := context.GetOk(r, foo.MyKey)
-		// ...
-	}
-
-And that's all about the basic usage. We discuss some other ideas below.
-
-Any type can be stored in the context. To enforce a given type, make the key
-private and wrap Get() and Set() to accept and return values of a specific
-type:
-
-	type key int
-
-	const mykey key = 0
-
-	// GetMyKey returns a value for this package from the request values.
-	func GetMyKey(r *http.Request) SomeType {
-		if rv := context.Get(r, mykey); rv != nil {
-			return rv.(SomeType)
-		}
-		return nil
-	}
-
-	// SetMyKey sets a value for this package in the request values.
-	func SetMyKey(r *http.Request, val SomeType) {
-		context.Set(r, mykey, val)
-	}
-
-Variables must be cleared at the end of a request, to remove all values
-that were stored. This can be done in an http.Handler, after a request was
-served. Just call Clear() passing the request:
-
-	context.Clear(r)
-
-...or use ClearHandler(), which conveniently wraps an http.Handler to clear
-variables at the end of a request lifetime.
-
-The Routers from the packages gorilla/mux and gorilla/pat call Clear()
-so if you are using either of them you don't need to clear the context manually.

-
-Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
-their respective handler.
-
-The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
-
-* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
-* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
-* URL hosts, paths and query values can have variables with an optional regular expression.
-* Registered URLs can be built, or "reversed", which helps maintaining references to resources.
-* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.

-
-## Install
-
-With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain:
-
-```sh
-go get -u github.com/gorilla/mux
-```
-
-## Examples
-
-Let's start registering a couple of URL paths and handlers:
-
-```go
-func main() {
-    r := mux.NewRouter()
-    r.HandleFunc("/", HomeHandler)
-    r.HandleFunc("/products", ProductsHandler)
-    r.HandleFunc("/articles", ArticlesHandler)
-    http.Handle("/", r)
-}
-```
-
-Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters.
-
-Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example:
-
-```go
-r := mux.NewRouter()
-r.HandleFunc("/products/{key}", ProductHandler)
-r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
-r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
-```
-
-The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
-
-```go
-func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
-    vars := mux.Vars(r)
-    w.WriteHeader(http.StatusOK)
-    fmt.Fprintf(w, "Category: %v\n", vars["category"])
-}
-```
-
-And this is all you need to know about the basic usage. More advanced options are explained below.
-
-### Matching Routes
-
-Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables:
-
-```go
-r := mux.NewRouter()
-// Only matches if domain is "www.example.com".
-r.Host("www.example.com")
-// Matches a dynamic subdomain.
-r.Host("{subdomain:[a-z]+}.domain.com")
-```
-
-There are several other matchers that can be added. To match path prefixes:
-
-```go
-r.PathPrefix("/products/")
-```
-
-...or HTTP methods:
-
-```go
-r.Methods("GET", "POST")
-```
-
-...or URL schemes:
-
-```go
-r.Schemes("https")
-```
-
-...or header values:
-
-```go
-r.Headers("X-Requested-With", "XMLHttpRequest")
-```
-
-...or query values:
-
-```go
-r.Queries("key", "value")
-```
-
-...or to use a custom matcher function:
-
-```go
-r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
-    return r.ProtoMajor == 0
-})
-```
-
-...and finally, it is possible to combine several matchers in a single route:
-
-```go
-r.HandleFunc("/products", ProductsHandler).
-  Host("www.example.com").
-  Methods("GET").
-  Schemes("http")
-```
-
-Routes are tested in the order they were added to the router. If two routes match, the first one wins:
-
-```go
-r := mux.NewRouter()
-r.HandleFunc("/specific", specificHandler)
-r.PathPrefix("/").Handler(catchAllHandler)
-```
-
-Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting".
-
-For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it:
-
-```go
-r := mux.NewRouter()
-s := r.Host("www.example.com").Subrouter()
-```
-
-Then register routes in the subrouter:
-
-```go
-s.HandleFunc("/products/", ProductsHandler)
-s.HandleFunc("/products/{key}", ProductHandler)
-s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
-```
-
-The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route.
-
-Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter.
-
-There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths:
-
-```go
-r := mux.NewRouter()
-s := r.PathPrefix("/products").Subrouter()
-// "/products/"
-s.HandleFunc("/", ProductsHandler)
-// "/products/{key}/"
-s.HandleFunc("/{key}/", ProductHandler)
-// "/products/{key}/details"
-s.HandleFunc("/{key}/details", ProductDetailsHandler)
-```
-
-
-### Static Files
-
-Note that the path provided to `PathPrefix()` represents a "wildcard": calling
-`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
-request that matches "/static/\*". This makes it easy to serve static files with mux:
-
-```go
-func main() {
-    var dir string
-
-    flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
-    flag.Parse()
-    r := mux.NewRouter()
-
-    // This will serve files under http://localhost:8000/static/<filename>
-    r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
-
-    srv := &http.Server{
-        Handler:      r,
-        Addr:         "127.0.0.1:8000",
-        // Good practice: enforce timeouts for servers you create!
-        WriteTimeout: 15 * time.Second,
-        ReadTimeout:  15 * time.Second,
-    }
-
-    log.Fatal(srv.ListenAndServe())
-}
-```
-
-### Registered URLs
-
-Now let's see how to build registered URLs.
-
-Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
-
-```go
-r := mux.NewRouter()
-r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
-  Name("article")
-```
-
-To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do:
-
-```go
-url, err := r.Get("article").URL("category", "technology", "id", "42")
-```
-
-...and the result will be a `url.URL` with the following path:
-
-```
-"/articles/technology/42"
-```
-
-This also works for host and query value variables:
-
-```go
-r := mux.NewRouter()
-r.Host("{subdomain}.domain.com").
-  Path("/articles/{category}/{id:[0-9]+}").
-  Queries("filter", "{filter}").
-  HandlerFunc(ArticleHandler).
-  Name("article")
-
-// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
-url, err := r.Get("article").URL("subdomain", "news",
-                                 "category", "technology",
-                                 "id", "42",
-                                 "filter", "gorilla")
-```
-
-All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match.
-
-Regex support also exists for matching Headers within a route. For example, we could do:
-
-```go
-r.HeadersRegexp("Content-Type", "application/(text|json)")
-```
-
-...and the route will match both requests with a Content-Type of `application/json` as well as `application/text`
-
-There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do:
-
-```go
-// "http://news.domain.com/"
-host, err := r.Get("article").URLHost("subdomain", "news")
-
-// "/articles/technology/42"
-path, err := r.Get("article").URLPath("category", "technology", "id", "42")
-```
-
-And if you use subrouters, host and path defined separately can be built as well:
-
-```go
-r := mux.NewRouter()
-s := r.Host("{subdomain}.domain.com").Subrouter()
-s.Path("/articles/{category}/{id:[0-9]+}").
-  HandlerFunc(ArticleHandler).
-  Name("article")
-
-// "http://news.domain.com/articles/technology/42"
-url, err := r.Get("article").URL("subdomain", "news",
-                                 "category", "technology",
-                                 "id", "42")
-```
-
-### Walking Routes
-
-The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router. For example,
-the following prints all of the registered routes:
-
-```go
-package main
-
-import (
-	"fmt"
-	"net/http"
-	"strings"
-
-	"github.com/gorilla/mux"
-)
-
-func handler(w http.ResponseWriter, r *http.Request) {
-	return
-}
-
-func main() {
-	r := mux.NewRouter()
-	r.HandleFunc("/", handler)
-	r.HandleFunc("/products", handler).Methods("POST")
-	r.HandleFunc("/articles", handler).Methods("GET")
-	r.HandleFunc("/articles/{id}", handler).Methods("GET", "PUT")
-	r.HandleFunc("/authors", handler).Queries("surname", "{surname}")
-	err := r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
-		pathTemplate, err := route.GetPathTemplate()
-		if err == nil {
-			fmt.Println("ROUTE:", pathTemplate)
-		}
-		pathRegexp, err := route.GetPathRegexp()
-		if err == nil {
-			fmt.Println("Path regexp:", pathRegexp)
-		}
-		queriesTemplates, err := route.GetQueriesTemplates()
-		if err == nil {
-			fmt.Println("Queries templates:", strings.Join(queriesTemplates, ","))
-		}
-		queriesRegexps, err := route.GetQueriesRegexp()
-		if err == nil {
-			fmt.Println("Queries regexps:", strings.Join(queriesRegexps, ","))
-		}
-		methods, err := route.GetMethods()
-		if err == nil {
-			fmt.Println("Methods:", strings.Join(methods, ","))
-		}
-		fmt.Println()
-		return nil
-	})
-
-	if err != nil {
-		fmt.Println(err)
-	}
-
-	http.Handle("/", r)
-}
-```
-
-### Graceful Shutdown
-
-Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
-
-```go
-package main
-
-import (
-    "context"
-    "flag"
-    "log"
-    "net/http"
-    "os"
-    "os/signal"
-    "time"
-
-    "github.com/gorilla/mux"
-)
-
-func main() {
-    var wait time.Duration
-    flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
-    flag.Parse()
-
-    r := mux.NewRouter()
-    // Add your routes as needed
-
-    srv := &http.Server{
-        Addr:         "0.0.0.0:8080",
-        // Good practice to set timeouts to avoid Slowloris attacks.
-        WriteTimeout: time.Second * 15,
-        ReadTimeout:  time.Second * 15,
-        IdleTimeout:  time.Second * 60,
-        Handler: r, // Pass our instance of gorilla/mux in.
-    }
-
-    // Run our server in a goroutine so that it doesn't block.
-    go func() {
-        if err := srv.ListenAndServe(); err != nil {
-            log.Println(err)
-        }
-    }()
-
-    c := make(chan os.Signal, 1)
-    // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
-    // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
-    signal.Notify(c, os.Interrupt)
-
-    // Block until we receive our signal.
-    <-c

-### Middleware
-
-Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
-Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
-
-Mux middlewares are defined using the de facto standard type:
-
-```go
-type MiddlewareFunc func(http.Handler) http.Handler
-```
-
-Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
-
-A very basic middleware which logs the URI of the request being handled could be written as:
-
-```go
-func loggingMiddleware(next http.Handler) http.Handler {
-    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-        // Do stuff here
-        log.Println(r.RequestURI)
-        // Call the next handler, which can be another middleware in the chain, or the final handler.
-        next.ServeHTTP(w, r)
-    })
-}
-```
-
-Middlewares can be added to a router using `Router.Use()`:
-
-```go
-r := mux.NewRouter()
-r.HandleFunc("/", handler)
-r.Use(loggingMiddleware)
-```
-
-A more complex authentication middleware, which maps session token to users, could be written as:
-
-```go
-// Define our struct
-type authenticationMiddleware struct {
-	tokenUsers map[string]string
-}
-
-// Initialize it somewhere
-func (amw *authenticationMiddleware) Populate() {
-	amw.tokenUsers["00000000"] = "user0"
-	amw.tokenUsers["aaaaaaaa"] = "userA"
-	amw.tokenUsers["05f717e5"] = "randomUser"
-	amw.tokenUsers["deadbeef"] = "user0"
-}
-
-// Middleware function, which will be called for each request
-func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
-    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-        token := r.Header.Get("X-Session-Token")
-
-        if user, found := amw.tokenUsers[token]; found {
-        	// We found the token in our map
-        	log.Printf("Authenticated user %s\n", user)
-        	// Pass down the request to the next middleware (or final handler)
-        	next.ServeHTTP(w, r)
-        } else {
-        	// Write an error and stop the handler chain
-        	http.Error(w, "Forbidden", http.StatusForbidden)
-        }
-    })
-}
-```
-
-```go
-r := mux.NewRouter()
-r.HandleFunc("/", handler)
-
-amw := authenticationMiddleware{}
-amw.Populate()
-
-r.Use(amw.Middleware)
-```
-
-Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
-
-### Testing Handlers
-
-Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
-
-First, our simple HTTP handler:
-
-```go
-// endpoints.go
-package main
-
-func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
-    // A very simple health check.
-    w.WriteHeader(http.StatusOK)
-    w.Header().Set("Content-Type", "application/json")
-
-    // In the future we could report back on the status of our DB, or our cache
-    // (e.g. Redis) by performing a simple PING, and include them in the response.
-    io.WriteString(w, `{"alive": true}`)
-}
-
-func main() {
-    r := mux.NewRouter()
-    r.HandleFunc("/health", HealthCheckHandler)
-
-    log.Fatal(http.ListenAndServe("localhost:8080", r))
-}
-```
-
-Our test code:
-
-```go
-// endpoints_test.go
-package main
-
-import (
-    "net/http"
-    "net/http/httptest"
-    "testing"
-)
-
-func TestHealthCheckHandler(t *testing.T) {
-    // Create a request to pass to our handler. We don't have any query parameters for now, so we'll
-    // pass 'nil' as the third parameter.
-    req, err := http.NewRequest("GET", "/health", nil)
-    if err != nil {
-        t.Fatal(err)
-    }
-
-    // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
-    rr := httptest.NewRecorder()
-    handler := http.HandlerFunc(HealthCheckHandler)
-
-    // Our handlers satisfy http.Handler, so we can call their ServeHTTP method
-    // directly and pass in our Request and ResponseRecorder.
-    handler.ServeHTTP(rr, req)
-
-    // Check the status code is what we expect.
-    if status := rr.Code; status != http.StatusOK {
-        t.Errorf("handler returned wrong status code: got %v want %v",
-            status, http.StatusOK)
-    }
-
-    // Check the response body is what we expect.
-    expected := `{"alive": true}`
-    if rr.Body.String() != expected {
-        t.Errorf("handler returned unexpected body: got %v want %v",
-            rr.Body.String(), expected)
-    }
-}
-```
-
-In the case that our routes have [variables](#examples), we can pass those in the request. We could write
-[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
-possible route variables as needed.
-
-```go
-// endpoints.go
-func main() {
-    r := mux.NewRouter()
-    // A route with a route variable:
-    r.HandleFunc("/metrics/{type}", MetricsHandler)
-
-    log.Fatal(http.ListenAndServe("localhost:8080", r))
-}
-```
-
-Our test file, with a table-driven test of `routeVariables`:
-
-```go
-// endpoints_test.go
-func TestMetricsHandler(t *testing.T) {
-    tt := []struct{
-        routeVariable string
-        shouldPass bool
-    }{
-        {"goroutines", true},
-        {"heap", true},
-        {"counters", true},
-        {"queries", true},
-        {"adhadaeqm3k", false},
-    }
-
-    for _, tc := range tt {
-        path := fmt.Sprintf("/metrics/%s", tc.routeVariable)
-        req, err := http.NewRequest("GET", path, nil)
-        if err != nil {
-            t.Fatal(err)
-        }
-
-        rr := httptest.NewRecorder()
-	
-	// Need to create a router that we can pass the request through so that the vars will be added to the context
-	router := mux.NewRouter()
-        router.HandleFunc("/metrics/{type}", MetricsHandler)
-        router.ServeHTTP(rr, req)
-
-        // In this case, our MetricsHandler returns a non-200 response
-        // for a route variable it doesn't know about.
-        if rr.Code == http.StatusOK && !tc.shouldPass {
-            t.Errorf("handler should have failed on routeVariable %s: got %v want %v",
-                tc.routeVariable, rr.Code, http.StatusOK)
-        }
-    }
-}
-```
-
-## Full Example
-
-Here's a complete, runnable example of a small `mux` based server:

-
-import (
-    "net/http"
-    "log"

-    w.Write([]byte("Gorilla!\n"))
-}
-
-func main() {
-    r := mux.NewRouter()
-    // Routes consist of a path and a handler function.
-    r.HandleFunc("/", YourHandler)
-
-    // Bind to a port and pass our router in
-    log.Fatal(http.ListenAndServe(":8000", r))

-Package mux implements a request router and dispatcher.
-
-The name mux stands for "HTTP request multiplexer". Like the standard
-http.ServeMux, mux.Router matches incoming requests against a list of
-registered routes and calls a handler for the route that matches the URL
-or other conditions. The main features are:
-
-	* Requests can be matched based on URL host, path, path prefix, schemes,
-	  header and query values, HTTP methods or using custom matchers.
-	* URL hosts, paths and query values can have variables with an optional
-	  regular expression.
-	* Registered URLs can be built, or "reversed", which helps maintaining
-	  references to resources.
-	* Routes can be used as subrouters: nested routes are only tested if the
-	  parent route matches. This is useful to define groups of routes that
-	  share common conditions like a host, a path prefix or other repeated
-	  attributes. As a bonus, this optimizes request matching.
-	* It implements the http.Handler interface so it is compatible with the
-	  standard http.ServeMux.
-
-Let's start registering a couple of URL paths and handlers:
-
-	func main() {
-		r := mux.NewRouter()
-		r.HandleFunc("/", HomeHandler)
-		r.HandleFunc("/products", ProductsHandler)
-		r.HandleFunc("/articles", ArticlesHandler)
-		http.Handle("/", r)
-	}
-
-Here we register three routes mapping URL paths to handlers. This is
-equivalent to how http.HandleFunc() works: if an incoming request URL matches
-one of the paths, the corresponding handler is called passing
-(http.ResponseWriter, *http.Request) as parameters.
-
-Paths can have variables. They are defined using the format {name} or
-{name:pattern}. If a regular expression pattern is not defined, the matched
-variable will be anything until the next slash. For example:
-
-	r := mux.NewRouter()
-	r.HandleFunc("/products/{key}", ProductHandler)
-	r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
-	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
-
-Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
-
-	r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
-
-The names are used to create a map of route variables which can be retrieved
-calling mux.Vars():
-
-	vars := mux.Vars(request)
-	category := vars["category"]
-
-Note that if any capturing groups are present, mux will panic() during parsing. To prevent
-this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
-"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
-when capturing groups were present.
-
-And this is all you need to know about the basic usage. More advanced options
-are explained below.
-
-Routes can also be restricted to a domain or subdomain. Just define a host
-pattern to be matched. They can also have variables:
-
-	r := mux.NewRouter()
-	// Only matches if domain is "www.example.com".
-	r.Host("www.example.com")
-	// Matches a dynamic subdomain.
-	r.Host("{subdomain:[a-z]+}.domain.com")
-
-There are several other matchers that can be added. To match path prefixes:
-
-	r.PathPrefix("/products/")
-
-...or HTTP methods:
-
-	r.Methods("GET", "POST")
-
-...or URL schemes:
-
-	r.Schemes("https")
-
-...or header values:
-
-	r.Headers("X-Requested-With", "XMLHttpRequest")
-
-...or query values:
-
-	r.Queries("key", "value")
-
-...or to use a custom matcher function:
-
-	r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
-		return r.ProtoMajor == 0
-	})
-
-...and finally, it is possible to combine several matchers in a single route:
-
-	r.HandleFunc("/products", ProductsHandler).
-	  Host("www.example.com").
-	  Methods("GET").
-	  Schemes("http")
-
-Setting the same matching conditions again and again can be boring, so we have
-a way to group several routes that share the same requirements.
-We call it "subrouting".
-
-For example, let's say we have several URLs that should only match when the
-host is "www.example.com". Create a route for that host and get a "subrouter"
-from it:
-
-	r := mux.NewRouter()
-	s := r.Host("www.example.com").Subrouter()
-
-Then register routes in the subrouter:
-
-	s.HandleFunc("/products/", ProductsHandler)
-	s.HandleFunc("/products/{key}", ProductHandler)
-	s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
-
-The three URL paths we registered above will only be tested if the domain is
-"www.example.com", because the subrouter is tested first. This is not
-only convenient, but also optimizes request matching. You can create
-subrouters combining any attribute matchers accepted by a route.
-
-Subrouters can be used to create domain or path "namespaces": you define
-subrouters in a central place and then parts of the app can register its
-paths relatively to a given subrouter.
-
-There's one more thing about subroutes. When a subrouter has a path prefix,
-the inner routes use it as base for their paths:
-
-	r := mux.NewRouter()
-	s := r.PathPrefix("/products").Subrouter()
-	// "/products/"
-	s.HandleFunc("/", ProductsHandler)
-	// "/products/{key}/"
-	s.HandleFunc("/{key}/", ProductHandler)
-	// "/products/{key}/details"
-	s.HandleFunc("/{key}/details", ProductDetailsHandler)
-
-Note that the path provided to PathPrefix() represents a "wildcard": calling
-PathPrefix("/static/").Handler(...) means that the handler will be passed any
-request that matches "/static/*". This makes it easy to serve static files with mux:
-
-	func main() {
-		var dir string
-
-		flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
-		flag.Parse()
-		r := mux.NewRouter()
-
-		// This will serve files under http://localhost:8000/static/<filename>
-		r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
-
-		srv := &http.Server{
-			Handler:      r,
-			Addr:         "127.0.0.1:8000",
-			// Good practice: enforce timeouts for servers you create!
-			WriteTimeout: 15 * time.Second,
-			ReadTimeout:  15 * time.Second,
-		}
-
-		log.Fatal(srv.ListenAndServe())
-	}
-
-Now let's see how to build registered URLs.
-
-Routes can be named. All routes that define a name can have their URLs built,
-or "reversed". We define a name calling Name() on a route. For example:
-
-	r := mux.NewRouter()
-	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
-	  Name("article")
-
-To build a URL, get the route and call the URL() method, passing a sequence of
-key/value pairs for the route variables. For the previous route, we would do:
-
-	url, err := r.Get("article").URL("category", "technology", "id", "42")
-
-...and the result will be a url.URL with the following path:
-
-	"/articles/technology/42"
-
-This also works for host and query value variables:
-
-	r := mux.NewRouter()
-	r.Host("{subdomain}.domain.com").
-	  Path("/articles/{category}/{id:[0-9]+}").
-	  Queries("filter", "{filter}").
-	  HandlerFunc(ArticleHandler).
-	  Name("article")
-
-	// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
-	url, err := r.Get("article").URL("subdomain", "news",
-	                                 "category", "technology",
-	                                 "id", "42",
-	                                 "filter", "gorilla")
-
-All variables defined in the route are required, and their values must
-conform to the corresponding patterns. These requirements guarantee that a
-generated URL will always match a registered route -- the only exception is
-for explicitly defined "build-only" routes which never match.
-
-Regex support also exists for matching Headers within a route. For example, we could do:
-
-	r.HeadersRegexp("Content-Type", "application/(text|json)")
-
-...and the route will match both requests with a Content-Type of `application/json` as well as
-`application/text`
-
-There's also a way to build only the URL host or path for a route:
-use the methods URLHost() or URLPath() instead. For the previous route,
-we would do:
-
-	// "http://news.domain.com/"
-	host, err := r.Get("article").URLHost("subdomain", "news")
-
-	// "/articles/technology/42"
-	path, err := r.Get("article").URLPath("category", "technology", "id", "42")
-
-And if you use subrouters, host and path defined separately can be built
-as well:
-
-	r := mux.NewRouter()
-	s := r.Host("{subdomain}.domain.com").Subrouter()
-	s.Path("/articles/{category}/{id:[0-9]+}").
-	  HandlerFunc(ArticleHandler).
-	  Name("article")
-
-	// "http://news.domain.com/articles/technology/42"
-	url, err := r.Get("article").URL("subdomain", "news",
-	                                 "category", "technology",
-	                                 "id", "42")
-
-Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
-
-	type MiddlewareFunc func(http.Handler) http.Handler
-
-Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
-
-A very basic middleware which logs the URI of the request being handled could be written as:
-
-	func simpleMw(next http.Handler) http.Handler {
-		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-			// Do stuff here
-			log.Println(r.RequestURI)
-			// Call the next handler, which can be another middleware in the chain, or the final handler.
-			next.ServeHTTP(w, r)
-		})
-	}
-
-Middlewares can be added to a router using `Router.Use()`:
-
-	r := mux.NewRouter()
-	r.HandleFunc("/", handler)
-	r.Use(simpleMw)
-
-A more complex authentication middleware, which maps session token to users, could be written as:
-
-	// Define our struct
-	type authenticationMiddleware struct {
-		tokenUsers map[string]string
-	}
-
-	// Initialize it somewhere
-	func (amw *authenticationMiddleware) Populate() {
-		amw.tokenUsers["00000000"] = "user0"
-		amw.tokenUsers["aaaaaaaa"] = "userA"
-		amw.tokenUsers["05f717e5"] = "randomUser"
-		amw.tokenUsers["deadbeef"] = "user0"
-	}
-
-	// Middleware function, which will be called for each request
-	func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
-		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-			token := r.Header.Get("X-Session-Token")
-
-			if user, found := amw.tokenUsers[token]; found {
-				// We found the token in our map
-				log.Printf("Authenticated user %s\n", user)
-				next.ServeHTTP(w, r)
-			} else {
-				http.Error(w, "Forbidden", http.StatusForbidden)
-			}
-		})
-	}
-
-	r := mux.NewRouter()
-	r.HandleFunc("/", handler)
-
-	amw := authenticationMiddleware{}
-	amw.Populate()
-
-	r.Use(amw.Middleware)
-
-Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

-# Gorilla WebSocket
-
-Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
-[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.
-
-[![Build Status](https://travis-ci.org/gorilla/websocket.svg?branch=master)](https://travis-ci.org/gorilla/websocket)
-[![GoDoc](https://godoc.org/github.com/gorilla/websocket?status.svg)](https://godoc.org/github.com/gorilla/websocket)

-### Documentation
-
-* [API Reference](http://godoc.org/github.com/gorilla/websocket)
-* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
-* [Command example](https://github.com/gorilla/websocket/tree/master/examples/command)
-* [Client and server example](https://github.com/gorilla/websocket/tree/master/examples/echo)
-* [File watch example](https://github.com/gorilla/websocket/tree/master/examples/filewatch)
-
-### Status
-
-The Gorilla WebSocket package provides a complete and tested implementation of
-the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
-package API is stable.
-
-### Installation
-
-    go get github.com/gorilla/websocket
-
-### Protocol Compliance
-
-The Gorilla WebSocket package passes the server tests in the [Autobahn Test
-Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
-subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).

-
-Notes:
-
-1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
-2. The application can get the type of a received data message by implementing
-   a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
-   function.
-3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
-  Read returns when the input buffer is full or a frame boundary is
-  encountered. Each call to Write sends a single frame message. The Gorilla
-  io.Reader and io.WriteCloser operate on a single WebSocket message.

-// Package websocket implements the WebSocket protocol defined in RFC 6455.
-//
-// Overview
-//
-// The Conn type represents a WebSocket connection. A server application calls
-// the Upgrader.Upgrade method from an HTTP request handler to get a *Conn:
-//
-//  var upgrader = websocket.Upgrader{
-//      ReadBufferSize:  1024,
-//      WriteBufferSize: 1024,
-//  }
-//
-//  func handler(w http.ResponseWriter, r *http.Request) {
-//      conn, err := upgrader.Upgrade(w, r, nil)
-//      if err != nil {
-//          log.Println(err)
-//          return
-//      }
-//      ... Use conn to send and receive messages.
-//  }
-//
-// Call the connection's WriteMessage and ReadMessage methods to send and
-// receive messages as a slice of bytes. This snippet of code shows how to echo
-// messages using these methods:
-//
-//  for {
-//      messageType, p, err := conn.ReadMessage()
-//      if err != nil {
-//          log.Println(err)
-//          return
-//      }
-//      if err := conn.WriteMessage(messageType, p); err != nil {
-//          log.Println(err)
-//          return
-//      }
-//  }
-//
-// In above snippet of code, p is a []byte and messageType is an int with value
-// websocket.BinaryMessage or websocket.TextMessage.
-//
-// An application can also send and receive messages using the io.WriteCloser
-// and io.Reader interfaces. To send a message, call the connection NextWriter
-// method to get an io.WriteCloser, write the message to the writer and close
-// the writer when done. To receive a message, call the connection NextReader
-// method to get an io.Reader and read until io.EOF is returned. This snippet
-// shows how to echo messages using the NextWriter and NextReader methods:
-//
-//  for {
-//      messageType, r, err := conn.NextReader()
-//      if err != nil {
-//          return
-//      }
-//      w, err := conn.NextWriter(messageType)
-//      if err != nil {
-//          return err
-//      }
-//      if _, err := io.Copy(w, r); err != nil {
-//          return err
-//      }
-//      if err := w.Close(); err != nil {
-//          return err
-//      }
-//  }
-//
-// Data Messages
-//
-// The WebSocket protocol distinguishes between text and binary data messages.
-// Text messages are interpreted as UTF-8 encoded text. The interpretation of
-// binary messages is left to the application.
-//
-// This package uses the TextMessage and BinaryMessage integer constants to
-// identify the two data message types. The ReadMessage and NextReader methods
-// return the type of the received message. The messageType argument to the
-// WriteMessage and NextWriter methods specifies the type of a sent message.
-//
-// It is the application's responsibility to ensure that text messages are
-// valid UTF-8 encoded text.
-//
-// Control Messages
-//
-// The WebSocket protocol defines three types of control messages: close, ping
-// and pong. Call the connection WriteControl, WriteMessage or NextWriter
-// methods to send a control message to the peer.
-//
-// Connections handle received close messages by calling the handler function
-// set with the SetCloseHandler method and by returning a *CloseError from the
-// NextReader, ReadMessage or the message Read method. The default close
-// handler sends a close message to the peer.
-//
-// Connections handle received ping messages by calling the handler function
-// set with the SetPingHandler method. The default ping handler sends a pong
-// message to the peer.
-//
-// Connections handle received pong messages by calling the handler function
-// set with the SetPongHandler method. The default pong handler does nothing.
-// If an application sends ping messages, then the application should set a
-// pong handler to receive the corresponding pong.
-//
-// The control message handler functions are called from the NextReader,
-// ReadMessage and message reader Read methods. The default close and ping
-// handlers can block these methods for a short time when the handler writes to
-// the connection.
-//
-// The application must read the connection to process close, ping and pong
-// messages sent from the peer. If the application is not otherwise interested
-// in messages from the peer, then the application should start a goroutine to
-// read and discard messages from the peer. A simple example is:
-//
-//  func readLoop(c *websocket.Conn) {
-//      for {
-//          if _, _, err := c.NextReader(); err != nil {
-//              c.Close()
-//              break
-//          }
-//      }
-//  }
-//
-// Concurrency
-//
-// Connections support one concurrent reader and one concurrent writer.
-//
-// Applications are responsible for ensuring that no more than one goroutine
-// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,
-// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and
-// that no more than one goroutine calls the read methods (NextReader,
-// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler)
-// concurrently.
-//
-// The Close and WriteControl methods can be called concurrently with all other
-// methods.
-//
-// Origin Considerations
-//
-// Web browsers allow Javascript applications to open a WebSocket connection to
-// any host. It's up to the server to enforce an origin policy using the Origin
-// request header sent by the browser.
-//
-// The Upgrader calls the function specified in the CheckOrigin field to check
-// the origin. If the CheckOrigin function returns false, then the Upgrade
-// method fails the WebSocket handshake with HTTP status 403.
-//
-// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail
-// the handshake if the Origin request header is present and the Origin host is
-// not equal to the Host request header.
-//
-// The deprecated package-level Upgrade function does not perform origin
-// checking. The application is responsible for checking the Origin header
-// before calling the Upgrade function.
-//
-// Compression EXPERIMENTAL
-//
-// Per message compression extensions (RFC 7692) are experimentally supported
-// by this package in a limited capacity. Setting the EnableCompression option
-// to true in Dialer or Upgrader will attempt to negotiate per message deflate
-// support.
-//
-//  var upgrader = websocket.Upgrader{
-//      EnableCompression: true,
-//  }
-//
-// If compression was successfully negotiated with the connection's peer, any
-// message received in compressed form will be automatically decompressed.
-// All Read methods will return uncompressed bytes.
-//
-// Per message compression of messages written to a connection can be enabled
-// or disabled by calling the corresponding Conn method:
-//
-//  conn.EnableWriteCompression(false)
-//
-// Currently this package does not support compression with "context takeover".
-// This means that messages must be compressed and decompressed in isolation,
-// without retaining sliding window or dictionary state across messages. For
-// more details refer to RFC 7692.
-//
-// Use of compression is experimental and may result in decreased performance.
