-## 安装
-
-要安装 Gin 软件包，需要先安装 Go 并设置 Go 工作区。
-
-1. 下载并安装 gin:
-
-```sh
-$ go get -u github.com/gin-gonic/gin
-```
-
-2. 将 gin 引入到代码中:
-
-```go
-import "github.com/gin-gonic/gin"
-```
-
-3. （可选）如果使用诸如`http.StatusOK`之类的常量，则需要引入 `net/http` 包。
-
-```go
-import "net/http"
-```
-
-### 使用 [Govendor](https://github.com/kardianos/govendor) 工具创建项目
-
-1. `go get` govendor
-
-```sh
-$ go get github.com/kardianos/govendor
-```
-2.创建项目并且 `cd` 到项目目录中
-
-```sh
-$ mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_"
-```
-
-3. 使用 govendor 初始化项目,并且引入gin
-
-```sh
-$ govendor init
-$ govendor fetch github.com/gin-gonic/gin@v1.3
-```
-
-4. 复制启动文件模板到项目目录中
-
-```sh
-$ curl https://raw.githubusercontent.com/gin-gonic/gin/master/examples/basic/main.go > main.go
-```
-
-5.启动项目
-
-```sh
-$ go run main.go
-```
-
-## 前提条件
-
-新版本的 Gin 需要 Go 1.6 或者更高版本，并且很快就会要求升级到 Go 1.7.
-
-## 快速开始
- 
-```sh
-# assume the following codes in example.go file
-$ cat example.go
-```
-
-```go
-package main
-
-import "github.com/gin-gonic/gin"
-
-func main() {
-	r := gin.Default()
-	r.GET("/ping", func(c *gin.Context) {
-		c.JSON(200, gin.H{
-			"message": "pong",
-		})
-	})
-	r.Run() // listen and serve on 0.0.0.0:8080
-}
-```
-
-```
-# run example.go and visit 0.0.0.0:8080/ping on browser
-$ go run example.go
-```
-
-## 性能测试
-
-Gin 使用自定义版本的 [HttpRouter](https://github.com/julienschmidt/httprouter)
-

-- (4): 每次重复的平均分配（allocs / op）越低越好
-
-## Gin v1 稳定版
-
-- [x] 零分配路由。
-- [x] 仍然是最快的http路由器和框架。
-- [x] 完整的单元测试支持
-- [x] 对战测试
-- [x] API冻结，使用新版本不需要修改原有代码。
-
-## 使用 [jsoniter](https://github.com/json-iterator/go) 
-
-Gin默认使用`encoding/json`解析json数据，但您可以通过`go build -tags=`更改为使用[jsoniter](https://github.com/json-iterator/go)。
-
-```sh
-$ go build -tags=jsoniter .
-```
-
-## API 示例
-
-### 使用GET, POST, PUT, PATCH, DELETE , OPTIONS 
-
-```go
-func main() {
-	// Disable Console Color
-	// gin.DisableConsoleColor()
-
-	// Creates a gin router with default middleware:
-	// logger and recovery (crash-free) middleware
-	router := gin.Default()
-
-	router.GET("/someGet", getting)
-	router.POST("/somePost", posting)
-	router.PUT("/somePut", putting)
-	router.DELETE("/someDelete", deleting)
-	router.PATCH("/somePatch", patching)
-	router.HEAD("/someHead", head)
-	router.OPTIONS("/someOptions", options)
-
-	// By default it serves on :8080 unless a
-	// PORT environment variable was defined.
-	router.Run()
-	// router.Run(":3000") for a hard coded port
-}
-```
-
-### 获取路由参数
-
-```go
-func main() {
-	router := gin.Default()
-
-	// This handler will match /user/john but will not match /user/ or /user
-	router.GET("/user/:name", func(c *gin.Context) {
-		name := c.Param("name")
-		c.String(http.StatusOK, "Hello %s", name)
-	})
-
-	// However, this one will match /user/john/ and also /user/john/send
-	// If no other routers match /user/john, it will redirect to /user/john/
-	router.GET("/user/:name/*action", func(c *gin.Context) {
-		name := c.Param("name")
-		action := c.Param("action")
-		message := name + " is " + action
-		c.String(http.StatusOK, message)
-	})
-
-	router.Run(":8080")
-}
-```
-
-### 获取url查询参数
-
-```go
-func main() {
-	router := gin.Default()
-
-	// Query string parameters are parsed using the existing underlying request object.
-	// The request responds to a url matching:  /welcome?firstname=Jane&lastname=Doe
-	router.GET("/welcome", func(c *gin.Context) {
-		firstname := c.DefaultQuery("firstname", "Guest")
-		lastname := c.Query("lastname") // shortcut for c.Request.URL.Query().Get("lastname")
-
-		c.String(http.StatusOK, "Hello %s %s", firstname, lastname)
-	})
-	router.Run(":8080")
-}
-```
-
-### Multipart Urlencoded 表单
-
-```go
-func main() {
-	router := gin.Default()
-
-	router.POST("/form_post", func(c *gin.Context) {
-		message := c.PostForm("message")
-		nick := c.DefaultPostForm("nick", "anonymous")
-
-		c.JSON(200, gin.H{
-			"status":  "posted",
-			"message": message,
-			"nick":    nick,
-		})
-	})
-	router.Run(":8080")
-}
-```
-
-### 获取post表单数据(url带查询参数)
-
-```
-POST /post?id=1234&page=1 HTTP/1.1
-Content-Type: application/x-www-form-urlencoded
-
-name=manu&message=this_is_great
-```
-
-```go
-func main() {
-	router := gin.Default()
-
-	router.POST("/post", func(c *gin.Context) {
-
-		id := c.Query("id")
-		page := c.DefaultQuery("page", "0")
-		name := c.PostForm("name")
-		message := c.PostForm("message")
-
-		fmt.Printf("id: %s; page: %s; name: %s; message: %s", id, page, name, message)
-	})
-	router.Run(":8080")
-}
-```
-
-```
-id: 1234; page: 1; name: manu; message: this_is_great
-```
-
-### 映射参数 表单参数
-
-```
-POST /post?ids[a]=1234&ids[b]=hello HTTP/1.1
-Content-Type: application/x-www-form-urlencoded
-
-names[first]=thinkerou&names[second]=tianou
-```
-
-```go
-func main() {
-	router := gin.Default()
-
-	router.POST("/post", func(c *gin.Context) {
-
-		ids := c.QueryMap("ids")
-		names := c.PostFormMap("names")
-
-		fmt.Printf("ids: %v; names: %v", ids, names)
-	})
-	router.Run(":8080")
-}
-```
-
-```
-ids: map[b:hello a:1234], names: map[second:tianou first:thinkerou]
-```
-
-### 上传文件
-
-#### 单个文件上传
-
-参考问题[＃774](https://github.com/gin-gonic/gin/issues/774)和详细[示例代码](examples/upload-file/single)。
-
-```go
-func main() {
-	router := gin.Default()
-	// Set a lower memory limit for multipart forms (default is 32 MiB)
-	// router.MaxMultipartMemory = 8 << 20  // 8 MiB
-	router.POST("/upload", func(c *gin.Context) {
-		// single file
-		file, _ := c.FormFile("file")
-		log.Println(file.Filename)
-
-		// Upload the file to specific dst.
-		// c.SaveUploadedFile(file, dst)
-
-		c.String(http.StatusOK, fmt.Sprintf("'%s' uploaded!", file.Filename))
-	})
-	router.Run(":8080")
-}
-```
-
-`curl`示例:
-
-```bash
-curl -X POST http://localhost:8080/upload \
-  -F "file=@/Users/appleboy/test.zip" \
-  -H "Content-Type: multipart/form-data"
-```
-
-#### 多文件上传
-
-查看详细信息[示例代码](examples/upload-file/multiple)。
-
-```go
-func main() {
-	router := gin.Default()
-	// Set a lower memory limit for multipart forms (default is 32 MiB)
-	// router.MaxMultipartMemory = 8 << 20  // 8 MiB
-	router.POST("/upload", func(c *gin.Context) {
-		// Multipart form
-		form, _ := c.MultipartForm()
-		files := form.File["upload[]"]
-
-		for _, file := range files {
-			log.Println(file.Filename)
-
-			// Upload the file to specific dst.
-			// c.SaveUploadedFile(file, dst)
-		}
-		c.String(http.StatusOK, fmt.Sprintf("%d files uploaded!", len(files)))
-	})
-	router.Run(":8080")
-}
-```
-
-`curl`示例:
-
-```bash
-curl -X POST http://localhost:8080/upload \
-  -F "upload[]=@/Users/appleboy/test1.zip" \
-  -F "upload[]=@/Users/appleboy/test2.zip" \
-  -H "Content-Type: multipart/form-data"
-```
-
-### 路由组
-
-```go
-func main() {
-	router := gin.Default()
-
-	// Simple group: v1
-	v1 := router.Group("/v1")
-	{
-		v1.POST("/login", loginEndpoint)
-		v1.POST("/submit", submitEndpoint)
-		v1.POST("/read", readEndpoint)
-	}
-
-	// Simple group: v2
-	v2 := router.Group("/v2")
-	{
-		v2.POST("/login", loginEndpoint)
-		v2.POST("/submit", submitEndpoint)
-		v2.POST("/read", readEndpoint)
-	}
-
-	router.Run(":8080")
-}
-```
-
-### 默认初始化 Gin
-
-用
-
-```go
-r := gin.New()
-```
-
-代替
-
-```go
-// Default With the Logger and Recovery middleware already attached
-r := gin.Default()
-```
-
-
-### 使用中间件
-```go
-func main() {
-	// Creates a router without any middleware by default
-	r := gin.New()
-
-	// Global middleware
-	// Logger middleware will write the logs to gin.DefaultWriter even if you set with GIN_MODE=release.
-	// By default gin.DefaultWriter = os.Stdout
-	r.Use(gin.Logger())
-
-	// Recovery middleware recovers from any panics and writes a 500 if there was one.
-	r.Use(gin.Recovery())
-
-	// Per route middleware, you can add as many as you desire.
-	r.GET("/benchmark", MyBenchLogger(), benchEndpoint)
-
-	// Authorization group
-	// authorized := r.Group("/", AuthRequired())
-	// exactly the same as:
-	authorized := r.Group("/")
-	// per group middleware! in this case we use the custom created
-	// AuthRequired() middleware just in the "authorized" group.
-	authorized.Use(AuthRequired())
-	{
-		authorized.POST("/login", loginEndpoint)
-		authorized.POST("/submit", submitEndpoint)
-		authorized.POST("/read", readEndpoint)
-
-		// nested group
-		testing := authorized.Group("testing")
-		testing.GET("/analytics", analyticsEndpoint)
-	}
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-### 如何记录日志
-```go
-func main() {
-    // Disable Console Color, you don't need console color when writing the logs to file.
-    gin.DisableConsoleColor()
-
-    // Logging to a file.
-    f, _ := os.Create("gin.log")
-    gin.DefaultWriter = io.MultiWriter(f)
-
-    // Use the following code if you need to write the logs to file and console at the same time.
-    // gin.DefaultWriter = io.MultiWriter(f, os.Stdout)
-
-    router := gin.Default()
-    router.GET("/ping", func(c *gin.Context) {
-        c.String(200, "pong")
-    })
-
-    router.Run(":8080")
-}
-```
-
-### 模型绑定和验证
-
-要将请求主体绑定到结构体中，请使用模型绑定。Gin目前支持JSON、XML、YAML和标准表单值的绑定（foo=bar＆boo=baz）。
-
-Gin使用[go-playground/validator.v8](https://github.com/go-playground/validator)进行验证。[完整文档](http://godoc.org/gopkg.in/go-playground/validator.v8#hdr-Baked_In_Validators_and_Tags)。
-
-使用时，需要在要绑定的所有字段上，设置相应的tag。例如，使用JSON绑定时，字段tag设置为`json:"fieldname"`。
-
-Gin提供了两类绑定方法：
-- **MustBind** - 
-   - **方法** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`, `BindYAML`
-   - **说明** - 这些方法属于`MustBindWith`的具体调用。如果发生绑定错误，则请求终止，并触发`c.AbortWithError(400,err).SetType(ErrorTypeBind)`。响应状态码被设置为400，`Content-Type`被设置为`text/plain;charset= UTF-8`。如果您在此之后尝试设置响应状态码，Gin会输出日志“ `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`。如果您希望更好地把控绑定，请考虑使用`ShouldBind`等效方法。
-- **ShouldBind** - 
-   - **方法** - `ShouldBind`，`ShouldBindJSON`，`ShouldBindXML`，`ShouldBindQuery`
-   - **说明** - 这些方法属于`ShouldBindWith`的具体调用。如果发生绑定错误，Gin会返回错误。由您处理错误以及请求。
-
-使用Bind方法时，Gin会根据Content-Type尝试推断如何绑定，如果您明确知道，您可以使用 `MustBindWith` 或 `ShouldBindWith`。
-
-指定必须绑定的字段，在该字段Tag上加上`binding:"required"` ，如果绑定时是空值，Gin会报错。
-
-```go
-// Binding from JSON
-type Login struct {
-	User     string `form:"user" json:"user" xml:"user"  binding:"required"`
-	Password string `form:"password" json:"password" xml:"password" binding:"required"`
-}
-
-func main() {

-			return
-		} 
-		
-		c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
-	})
-
-	// Example for binding a HTML form (user=manu&password=123)
-	router.POST("/loginForm", func(c *gin.Context) {
-		var form Login
-		// This will infer what binder to use depending on the content-type header.
-		if err := c.ShouldBind(&form); err != nil {
-			c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
-			return
-		}
-		
-		if form.User != "manu" || form.Password != "123" {

-		c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	router.Run(":8080")
-}
-```
-
-**测试**
-```shell

-
-import (
-	"github.com/gin-gonic/gin"
-)
-
-type LoginForm struct {
-	User     string `form:"user" binding:"required"`
-	Password string `form:"password" binding:"required"`
-}
-
-func main() {
-	router := gin.Default()
-	router.POST("/login", func(c *gin.Context) {
-		// you can bind multipart form with explicit binding declaration:
-		// c.ShouldBindWith(&form, binding.Form)
-		// or you can simply use autobinding with ShouldBind method:
-		var form LoginForm
-		// in this case proper binding will be automatically selected
-		if c.ShouldBind(&form) == nil {
-			if form.User == "user" && form.Password == "password" {
-				c.JSON(200, gin.H{"status": "you are logged in"})
-			} else {
-				c.JSON(401, gin.H{"status": "unauthorized"})
-			}
-		}
-	})
-	router.Run(":8080")
-}
-```
-
-测试:
-```sh
-$ curl -v --form user=user --form password=password http://localhost:8080/login
-```
-
-### XML JSON YAML ProtoBuf 渲染
-
-```go
-func main() {
-	r := gin.Default()
-
-	// gin.H is a shortcut for map[string]interface{}
-	r.GET("/someJSON", func(c *gin.Context) {
-		c.JSON(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
-	})
-
-	r.GET("/moreJSON", func(c *gin.Context) {
-		// You also can use a struct
-		var msg struct {
-			Name    string `json:"user"`
-			Message string
-			Number  int
-		}
-		msg.Name = "Lena"
-		msg.Message = "hey"
-		msg.Number = 123
-		// Note that msg.Name becomes "user" in the JSON
-		// Will output  :   {"user": "Lena", "Message": "hey", "Number": 123}
-		c.JSON(http.StatusOK, msg)
-	})
-
-	r.GET("/someXML", func(c *gin.Context) {
-		c.XML(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
-	})
-
-	r.GET("/someYAML", func(c *gin.Context) {
-		c.YAML(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
-	})
-
-	r.GET("/someProtoBuf", func(c *gin.Context) {
-		reps := []int64{int64(1), int64(2)}
-		label := "test"
-		// The specific definition of protobuf is written in the testdata/protoexample file.
-		data := &protoexample.Test{
-			Label: &label,
-			Reps:  reps,
-		}
-		// Note that data becomes binary data in the response
-		// Will output protoexample.Test protobuf serialized data
-		c.ProtoBuf(http.StatusOK, data)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-#### SecureJSON
-
-使用 SecureJSON 来防止 json 劫持。 如果给定的结构是数组值，则默认预 置`“while(1)，”` 到响应体。
-
-```go
-func main() {
-	r := gin.Default()
-
-	// You can also use your own secure json prefix
-	// r.SecureJsonPrefix(")]}',\n")
-
-	r.GET("/someJSON", func(c *gin.Context) {
-		names := []string{"lena", "austin", "foo"}
-
-		// Will output  :   while(1);["lena","austin","foo"]
-		c.SecureJSON(http.StatusOK, names)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-#### JSONP
-
-使用 JSONP 从不同域中的服务器请求数据。 如果查询参数回调存在，则将回调添加到响应正文。
-
-```go
-func main() {
-	r := gin.Default()
-
-	r.GET("/JSONP?callback=x", func(c *gin.Context) {
-		data := map[string]interface{}{
-			"foo": "bar",
-		}
-		
-		//callback is x
-		// Will output  :   x({\"foo\":\"bar\"})
-		c.JSONP(http.StatusOK, data)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-#### AsciiJSON
-
-使用 Ascii JSON 生成具有转义的非 ASCII 字符的仅 ASCII JSON。
-
-```go
-func main() {
-	r := gin.Default()
-
-	r.GET("/someJSON", func(c *gin.Context) {
-		data := map[string]interface{}{
-			"lang": "GO语言",
-			"tag":  "<br>",
-		}
-
-		// will output : {"lang":"GO\u8bed\u8a00","tag":"\u003cbr\u003e"}
-		c.AsciiJSON(http.StatusOK, data)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-#### PureJSON
-
-通常，JSON使用unicode替换特殊HTML字符，例如 `<` 变为 `\ u003c`。 如果要按字面意思对这些字符进行编码，则可以使用 PureJSON。
-Go 1.6及更低版本无法使用此功能。
-
-```go
-func main() {
-	r := gin.Default()
-	
-	// Serves unicode entities
-	r.GET("/json", func(c *gin.Context) {
-		c.JSON(200, gin.H{
-			"html": "<b>Hello, world!</b>",
-		})
-	})
-	
-	// Serves literal characters
-	r.GET("/purejson", func(c *gin.Context) {
-		c.PureJSON(200, gin.H{
-			"html": "<b>Hello, world!</b>",
-		})
-	})
-	
-	// listen and serve on 0.0.0.0:8080
-	r.Run(":8080)
-}
-```
-
-### 静态文件服务
-
-```go
-func main() {
-	router := gin.Default()
-	router.Static("/assets", "./assets")
-	router.StaticFS("/more_static", http.Dir("my_file_system"))
-	router.StaticFile("/favicon.ico", "./resources/favicon.ico")
-
-	// Listen and serve on 0.0.0.0:8080
-	router.Run(":8080")
-}
-```
-
-### 从 reader 读取数据
-
-```go
-func main() {
-	router := gin.Default()
-	router.GET("/someDataFromReader", func(c *gin.Context) {
-		response, err := http.Get("https://raw.githubusercontent.com/gin-gonic/logo/master/color.png")
-		if err != nil || response.StatusCode != http.StatusOK {
-			c.Status(http.StatusServiceUnavailable)
-			return
-		}
-
-		reader := response.Body
-		contentLength := response.ContentLength
-		contentType := response.Header.Get("Content-Type")
-
-		extraHeaders := map[string]string{
-			"Content-Disposition": `attachment; filename="gopher.png"`,
-		}
-
-		c.DataFromReader(http.StatusOK, contentLength, contentType, reader, extraHeaders)
-	})
-	router.Run(":8080")
-}
-```
-
-### HTML 渲染
-
-使用LoadHTMLGlob()或LoadHTMLFiles()
-
-```go
-func main() {
-	router := gin.Default()
-	router.LoadHTMLGlob("templates/*")
-	//router.LoadHTMLFiles("templates/template1.html", "templates/template2.html")
-	router.GET("/index", func(c *gin.Context) {
-		c.HTML(http.StatusOK, "index.tmpl", gin.H{
-			"title": "Main website",
-		})
-	})
-	router.Run(":8080")
-}
-```
-
-templates/index.tmpl
-
-```html
-<html>
-	<h1>
-		{{ .title }}
-	</h1>
-</html>
-```
-
-在不同目录中使用具有相同名称的模板
-
-```go
-func main() {
-	router := gin.Default()
-	router.LoadHTMLGlob("templates/**/*")
-	router.GET("/posts/index", func(c *gin.Context) {
-		c.HTML(http.StatusOK, "posts/index.tmpl", gin.H{
-			"title": "Posts",
-		})
-	})
-	router.GET("/users/index", func(c *gin.Context) {
-		c.HTML(http.StatusOK, "users/index.tmpl", gin.H{
-			"title": "Users",
-		})
-	})
-	router.Run(":8080")
-}
-```
-
-templates/posts/index.tmpl
-
-```html
-{{ define "posts/index.tmpl" }}
-<html><h1>
-	{{ .title }}
-</h1>
-<p>Using posts/index.tmpl</p>
-</html>
-{{ end }}
-```
-
-templates/users/index.tmpl
-
-```html
-{{ define "users/index.tmpl" }}
-<html><h1>
-	{{ .title }}
-</h1>
-<p>Using users/index.tmpl</p>
-</html>
-{{ end }}
-```
-
-#### 自定义模板渲染器
-
-您还可以使用自己的 html 模板渲染
-
-```go
-import "html/template"
-
-func main() {
-	router := gin.Default()
-	html := template.Must(template.ParseFiles("file1", "file2"))
-	router.SetHTMLTemplate(html)
-	router.Run(":8080")
-}
-```
-
-#### 自定义分隔符
-
-您可以使用自定义分隔
-
-```go
-	r := gin.Default()
-	r.Delims("{[{", "}]}")
-	r.LoadHTMLGlob("/path/to/templates")
-```
-
-#### 自定义模板功能
-
-查看详细信息[示例代码](examples/template)。
-
-main.go
-
-```go
-import (
-    "fmt"
-    "html/template"
-    "net/http"
-    "time"
-
-    "github.com/gin-gonic/gin"
-)
-
-func formatAsDate(t time.Time) string {
-    year, month, day := t.Date()
-    return fmt.Sprintf("%d%02d/%02d", year, month, day)
-}
-
-func main() {
-    router := gin.Default()
-    router.Delims("{[{", "}]}")
-    router.SetFuncMap(template.FuncMap{
-        "formatAsDate": formatAsDate,
-    })
-    router.LoadHTMLFiles("./testdata/template/raw.tmpl")
-
-    router.GET("/raw", func(c *gin.Context) {
-        c.HTML(http.StatusOK, "raw.tmpl", map[string]interface{}{
-            "now": time.Date(2017, 07, 01, 0, 0, 0, 0, time.UTC),
-        })
-    })
-
-    router.Run(":8080")
-}
-
-```
-
-raw.tmpl
-
-```html
-日期: {[{.now | formatAsDate}]}
-```
-
-结果:
-```
-Date: 2017/07/01
-```
-
-### 多模板
-
-Gin 允许默认只使用一个 html 模板。 检查[多模板渲染](https://github.com/gin-contrib/multitemplate)以使用 go 1.6 `block template` 等功能。
-
-### 重定向
-
-Issuing a HTTP redirect is easy. Both internal and external locations are supported.
-
-```go
-r.GET("/test", func(c *gin.Context) {
-	c.Redirect(http.StatusMovedPermanently, "http://www.google.com/")
-})
-```
-
-
-发出路由器重定向，使用如下的“HandleContext”。
-
-``` go
-r.GET("/test", func(c *gin.Context) {
-    c.Request.URL.Path = "/test2"
-    r.HandleContext(c)
-})
-r.GET("/test2", func(c *gin.Context) {
-    c.JSON(200, gin.H{"hello": "world"})
-})
-```
-
-
-###  自定义中间件
-
-```go
-func Logger() gin.HandlerFunc {
-	return func(c *gin.Context) {
-		t := time.Now()
-
-		// Set example variable
-		c.Set("example", "12345")
-
-		// before request
-
-		c.Next()
-
-		// after request
-		latency := time.Since(t)
-		log.Print(latency)
-
-		// access the status we are sending
-		status := c.Writer.Status()
-		log.Println(status)
-	}
-}
-
-func main() {
-	r := gin.New()
-	r.Use(Logger())
-
-	r.GET("/test", func(c *gin.Context) {
-		example := c.MustGet("example").(string)
-
-		// it would print: "12345"
-		log.Println(example)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-### BasicAuth() 中间件
-
-```go
-// simulate some private data
-var secrets = gin.H{
-	"foo":    gin.H{"email": "foo@bar.com", "phone": "123433"},
-	"austin": gin.H{"email": "austin@example.com", "phone": "666"},
-	"lena":   gin.H{"email": "lena@guapa.com", "phone": "523443"},
-}
-
-func main() {
-	r := gin.Default()
-
-	// Group using gin.BasicAuth() middleware
-	// gin.Accounts is a shortcut for map[string]string
-	authorized := r.Group("/admin", gin.BasicAuth(gin.Accounts{
-		"foo":    "bar",
-		"austin": "1234",
-		"lena":   "hello2",
-		"manu":   "4321",
-	}))
-
-	// /admin/secrets endpoint
-	// hit "localhost:8080/admin/secrets
-	authorized.GET("/secrets", func(c *gin.Context) {
-		// get user, it was set by the BasicAuth middleware
-		user := c.MustGet(gin.AuthUserKey).(string)
-		if secret, ok := secrets[user]; ok {
-			c.JSON(http.StatusOK, gin.H{"user": user, "secret": secret})
-		} else {
-			c.JSON(http.StatusOK, gin.H{"user": user, "secret": "NO SECRET :("})
-		}
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```

-当在中间件或handler中启动新的Goroutines时，不能使用原始上下文，必须使用只读副本。
-
-```go
-func main() {
-	r := gin.Default()
-
-	r.GET("/long_async", func(c *gin.Context) {
-		// create copy to be used inside the goroutine
-		cCp := c.Copy()
-		go func() {
-			// simulate a long task with time.Sleep(). 5 seconds
-			time.Sleep(5 * time.Second)
-
-			// note that you are using the copied context "cCp", IMPORTANT
-			log.Println("Done! in path " + cCp.Request.URL.Path)
-		}()
-	})
-
-	r.GET("/long_sync", func(c *gin.Context) {
-		// simulate a long task with time.Sleep(). 5 seconds
-		time.Sleep(5 * time.Second)
-
-		// since we are NOT using a goroutine, we do not have to copy the context
-		log.Println("Done! in path " + c.Request.URL.Path)
-	})
-
-	// Listen and serve on 0.0.0.0:8080
-	r.Run(":8080")
-}
-```
-
-### 自定义 HTTP 配置
-
-直接使用`http.ListenAndServe()`，如下所示：
-
-```go
-func main() {
-	router := gin.Default()
-	http.ListenAndServe(":8080", router)
-}
-```
-or
-
-```go
-func main() {
-	router := gin.Default()
-
-	s := &http.Server{
-		Addr:           ":8080",
-		Handler:        router,
-		ReadTimeout:    10 * time.Second,
-		WriteTimeout:   10 * time.Second,
-		MaxHeaderBytes: 1 << 20,
-	}
-	s.ListenAndServe()
-}
-```
-
-###  Let's Encrypt 支持
-
-一行代码支持 LetsEncrypt HTTPS示例。
-
-[embedmd]:# (examples/auto-tls/example1/main.go go)
-```go
-package main
-
-import (
-	"log"
-
-	"github.com/gin-gonic/autotls"
-	"github.com/gin-gonic/gin"
-)
-
-func main() {
-	r := gin.Default()
-
-	// Ping handler
-	r.GET("/ping", func(c *gin.Context) {
-		c.String(200, "pong")
-	})
-
-	log.Fatal(autotls.Run(r, "example1.com", "example2.com"))
-}
-```
-
-autocert使用示例。
-
-[embedmd]:# (examples/auto-tls/example2/main.go go)
-```go

-)
-
-func main() {
-	r := gin.Default()
-
-	// Ping handler
-	r.GET("/ping", func(c *gin.Context) {
-		c.String(200, "pong")
-	})
-
-	m := autocert.Manager{
-		Prompt:     autocert.AcceptTOS,
-		HostPolicy: autocert.HostWhitelist("example1.com", "example2.com"),
-		Cache:      autocert.DirCache("/var/www/.cache"),
-	}
-
-	log.Fatal(autotls.RunWithManager(r, &m))

-### 使用 Gin 运行多个服务
-
-请参阅[问题](https://github.com/gin-gonic/gin/issues/346)并尝试以下示例：
-

-### 优雅重启或停止
-
-您想要优雅地重启或停止您的Web服务器吗？
-有一些方法可以做到这一点。
-
-我们可以使用[fvbock/endless](https://github.com/fvbock/endless)来替换默认的`ListenAndServe`。 有关更多详细信息，请参阅问题[＃296](https://github.com/gin-gonic/gin/issues/296)。
-
-```go
-router := gin.Default()
-router.GET("/", handler)
-// [...]
-endless.ListenAndServe(":4242", router)
-```
-
-替代方案：
-
-* [manners](https://github.com/braintree/manners)：礼貌的Go HTTP服务器，可以正常关闭。
-* [graceful](https://github.com/tylerb/graceful)：Graceful是一个Go包，可以正常关闭http.Handler服务器。
-* [grace](https://github.com/facebookgo/grace)：Go服务器的平滑重启和零停机时间部署。
-
-如果您使用的是Go 1.8，可以考虑使用http.Server的内置[Shutdown()](https://golang.org/pkg/net/http/#Server.Shutdown)方法进行正常关机。
-请参阅gin的完整[graceful-shutdown](/examples /graceful-shutdown)示例。
-
-[embedmd]:# (examples/graceful-shutdown/graceful-shutdown/server.go go)
-```go
-// +build go1.8
-
-package main
-
-import (
-	"context"
-	"log"
-	"net/http"
-	"os"
-	"os/signal"
-	"time"
-
-	"github.com/gin-gonic/gin"
-)
-
-func main() {
-	router := gin.Default()
-	router.GET("/", func(c *gin.Context) {
-		time.Sleep(5 * time.Second)
-		c.String(http.StatusOK, "Welcome Gin Server")
-	})
-
-	srv := &http.Server{
-		Addr:    ":8080",
-		Handler: router,
-	}
-
-	go func() {
-		// service connections
-		if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed {
-			log.Fatalf("listen: %s\n", err)
-		}
-	}()
-
-	// Wait for interrupt signal to gracefully shutdown the server with
-	// a timeout of 5 seconds.
-	quit := make(chan os.Signal)
-	signal.Notify(quit, os.Interrupt)
-	<-quit
-	log.Println("Shutdown Server ...")
-
-	ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
-	defer cancel()
-	if err := srv.Shutdown(ctx); err != nil {
-		log.Fatal("Server Shutdown:", err)
-	}
-	log.Println("Server exiting")
-}
-```
-
-### 静态资源嵌入
-
-使用[go-assets](https://github.com/jessevdk/go-assets)将静态资源打包到可执行文件中。
-
-```go
-func main() {
-	r := gin.New()
-
-	t, err := loadTemplate()
-	if err != nil {
-		panic(err)
-	}
-	r.SetHTMLTemplate(t)
-
-	r.GET("/", func(c *gin.Context) {
-		c.HTML(http.StatusOK, "/html/index.tmpl",nil)
-	})
-	r.Run(":8080")
-}
-
-// loadTemplate loads templates embedded by go-assets-builder
-func loadTemplate() (*template.Template, error) {
-	t := template.New("")
-	for name, file := range Assets.Files {
-		if file.IsDir() || !strings.HasSuffix(name, ".tmpl") {
-			continue
-		}
-		h, err := ioutil.ReadAll(file)
-		if err != nil {
-			return nil, err
-		}
-		t, err = t.New(name).Parse(string(h))
-		if err != nil {
-			return nil, err
-		}
-	}
-	return t, nil
-}
-```
-
-请参阅`examples/assets-in-binary`目录中的完整示例。
-
-### 表单数据绑定到自定义结构体
-
-以下示例使用自定义结构体：
-
-```go
-type StructA struct {
-    FieldA string `form:"field_a"`
-}
-
-type StructB struct {
-    NestedStruct StructA
-    FieldB string `form:"field_b"`
-}
-
-type StructC struct {
-    NestedStructPointer *StructA
-    FieldC string `form:"field_c"`
-}
-
-type StructD struct {
-    NestedAnonyStruct struct {
-        FieldX string `form:"field_x"`
-    }
-    FieldD string `form:"field_d"`
-}
-
-func GetDataB(c *gin.Context) {
-    var b StructB
-    c.Bind(&b)
-    c.JSON(200, gin.H{
-        "a": b.NestedStruct,
-        "b": b.FieldB,
-    })
-}
-
-func GetDataC(c *gin.Context) {
-    var b StructC
-    c.Bind(&b)
-    c.JSON(200, gin.H{
-        "a": b.NestedStructPointer,
-        "c": b.FieldC,
-    })
-}
-
-func GetDataD(c *gin.Context) {
-    var b StructD
-    c.Bind(&b)
-    c.JSON(200, gin.H{
-        "x": b.NestedAnonyStruct,
-        "d": b.FieldD,
-    })
-}
-
-func main() {
-    r := gin.Default()
-    r.GET("/getb", GetDataB)
-    r.GET("/getc", GetDataC)
-    r.GET("/getd", GetDataD)
-
-    r.Run()
-}
-```
-
-`curl`命令示例：
-
-```
-$ curl "http://localhost:8080/getb?field_a=hello&field_b=world"
-{"a":{"FieldA":"hello"},"b":"world"}
-$ curl "http://localhost:8080/getc?field_a=hello&field_c=world"
-{"a":{"FieldA":"hello"},"c":"world"}
-$ curl "http://localhost:8080/getd?field_x=hello&field_d=world"
-{"d":"world","x":{"FieldX":"hello"}}
-```
-
-**注意**:不支持以下格式结构体：
-
-```go
-type StructX struct {
-    X struct {} `form:"name_x"` // HERE have form
-}
-
-type StructY struct {
-    Y StructX `form:"name_y"` // HERE have form
-}
-
-type StructZ struct {
-    Z *StructZ `form:"name_z"` // HERE have form
-}
-```
-
-一句话，现在只支持没有`form`的嵌套结构体。
-
-### 将request body绑定到不同的结构体中
-
-一般通过调用`c.Request.Body`方法绑定数据，但不能多次调用这个方法。
-
-```go
-type formA struct {
-  Foo string `json:"foo" xml:"foo" binding:"required"`
-}
-
-type formB struct {
-  Bar string `json:"bar" xml:"bar" binding:"required"`
-}
-
-func SomeHandler(c *gin.Context) {
-  objA := formA{}
-  objB := formB{}
-  // This c.ShouldBind consumes c.Request.Body and it cannot be reused.
-  if errA := c.ShouldBind(&objA); errA == nil {
-    c.String(http.StatusOK, `the body should be formA`)
-  // Always an error is occurred by this because c.Request.Body is EOF now.
-  } else if errB := c.ShouldBind(&objB); errB == nil {
-    c.String(http.StatusOK, `the body should be formB`)
-  } else {
-    ...
-  }
-}
-```
-
-为此，要想多次绑定，需要使用`c.ShouldBindBodyWith`.
-
-```go
-func SomeHandler(c *gin.Context) {
-  objA := formA{}
-  objB := formB{}
-  // This reads c.Request.Body and stores the result into the context.
-  if errA := c.ShouldBindBodyWith(&objA, binding.JSON); errA == nil {
-    c.String(http.StatusOK, `the body should be formA`)
-  // At this time, it reuses body stored in the context.
-  } else if errB := c.ShouldBindBodyWith(&objB, binding.JSON); errB == nil {
-    c.String(http.StatusOK, `the body should be formB JSON`)
-  // And it can accepts other formats
-  } else if errB2 := c.ShouldBindBodyWith(&objB, binding.XML); errB2 == nil {
-    c.String(http.StatusOK, `the body should be formB XML`)
-  } else {
-    ...
-  }
-}
-```
-
-
-* `c.ShouldBindBodyWith`会在绑定之前将body存储到上下文中。 这会对性能造成轻微影响，如果调用一次就能完成绑定的话，那就不要用这个方法。
-* 只有某些格式需要此功能 ，如`JSON`、`XML`、`MsgPack`、`ProtoBuf`。 对于其他格式，如`Query`、`Form`、`FormPost`、`FormMultipart`可以多次调用`c.ShouldBind()`而不会造成任任何性能损失（见[＃1341](https://github.com/gin-gonic/gin/pull/1341)）。

-### http2 server 推送
-
-
-http.Pusher仅支持go1.8 +。 有关详细信息，请参阅[golang blog](https://blog.golang.org/h2push)。
-
-[embedmd]:# (examples/http-pusher/main.go go)
-```go
-package main
-
-import (
-	"html/template"
-	"log"
-
-	"github.com/gin-gonic/gin"
-)
-
-var html = template.Must(template.New("https").Parse(`
-<html>
-<head>
-  <title>Https Test</title>
-  <script src="/assets/app.js"></script>
-</head>
-<body>
-  <h1 style="color:red;">Welcome, Ginner!</h1>
-</body>
-</html>
-`))
-
-func main() {
-	r := gin.Default()
-	r.Static("/assets", "./assets")
-	r.SetHTMLTemplate(html)
-
-	r.GET("/", func(c *gin.Context) {
-		if pusher := c.Writer.Pusher(); pusher != nil {
-			// use pusher.Push() to do server push
-			if err := pusher.Push("/assets/app.js", nil); err != nil {
-				log.Printf("Failed to push: %v", err)
-			}
-		}
-		c.HTML(200, "https", gin.H{
-			"status": "success",
-		})
-	})
-
-	// Listen and Server in https://127.0.0.1:8080
-	r.RunTLS(":8080", "./testdata/server.pem", "./testdata/server.key")
-}
-```
-
-### 定义路由日志的格式
-
-默认的路由日志格式：
-```
-[GIN-debug] POST   /foo                      --> main.main.func1 (3 handlers)
-[GIN-debug] GET    /bar                      --> main.main.func2 (3 handlers)
-[GIN-debug] GET    /status                   --> main.main.func3 (3 handlers)
-```
-
-如果要以指的格式（例如JSON，Key Values或其他格式）记录信息，则可以使用`gin.DebugPrintRouteFunc`指定格式。
-在下面的示例中，我们使用标准日志包记录所有路由，但您可以使用其他满足需求的日志工具。
-```go
-import (
-	"log"
-	"net/http"
-
-	"github.com/gin-gonic/gin"
-)
-
-func main() {
-	r := gin.Default()
-	gin.DebugPrintRouteFunc = func(httpMethod, absolutePath, handlerName string, nuHandlers int) {
-		log.Printf("endpoint %v %v %v %v\n", httpMethod, absolutePath, handlerName, nuHandlers)
-	}
-
-	r.POST("/foo", func(c *gin.Context) {
-		c.JSON(http.StatusOK, "foo")
-	})
-
-	r.GET("/bar", func(c *gin.Context) {
-		c.JSON(http.StatusOK, "bar")
-	})
-
-	r.GET("/status", func(c *gin.Context) {
-		c.JSON(http.StatusOK, "ok")
-	})
-
-	// Listen and Server in http://0.0.0.0:8080
-	r.Run()
-}
-```
-### 如何使用Cookie
-
-```go
-import (
-    "fmt"
-
-    "github.com/gin-gonic/gin"
-)
-
-func main() {
-
-    router := gin.Default()
-
-    router.GET("/cookie", func(c *gin.Context) {
-
-        cookie, err := c.Cookie("gin_cookie")
-
-        if err != nil {
-            cookie = "NotSet"
-            c.SetCookie("gin_cookie", "test", 3600, "/", "localhost", false, true)
-        }
-
-        fmt.Printf("Cookie value: %s \n", cookie)
-    })
-
-    router.Run()
-}
-```
-
-## 测试
-
-HTTP测试首选`net/http/httptest`包。
-
-```go
-package main
-
-func setupRouter() *gin.Engine {
-	r := gin.Default()
-	r.GET("/ping", func(c *gin.Context) {
-		c.String(200, "pong")
-	})
-	return r
-}
-
-func main() {
-	r := setupRouter()
-	r.Run(":8080")
-}
-```
-
-上面这段代码的测试用例：
-
-```go
-package main
-
-import (
-	"net/http"
-	"net/http/httptest"
-	"testing"
-
-	"github.com/stretchr/testify/assert"
-)
-
-func TestPingRoute(t *testing.T) {
-	router := setupRouter()
-
-	w := httptest.NewRecorder()
-	req, _ := http.NewRequest("GET", "/ping", nil)
-	router.ServeHTTP(w, req)
-
-	assert.Equal(t, 200, w.Code)
-	assert.Equal(t, "pong", w.Body.String())
-}
-```
