### 在Mac上安装 `Go` ###

由于我的环境是Mac ，直接下载 `Pkg` ，win 和 linux 下载地址都在这里 。[Go安装包下载][Go]

#mac 直接安装安装包
    go1.10.1.darwin-amd64.pkg
    
    #将 go 路径添加到 profile /usr/local/go/bin 
    export  PATH = /usr/local/go/bin:$PATH 
    
    source /etc/profile
    
    leon:go leon$ go version
    go version go1.10.1 darwin/amd64

### 安装 `Gin` 包 ###

`go get gopkg.in/gin-gonic/gin.v1`

### `Gin` 的 `http` 路由用例 ###

package main
    import (
        "gopkg.in/gin-gonic/gin.v1"
        "net/http"
        "fmt"
    )
    
    
    func main(){
        // only set in Production
        // gin.SetMode(gin.ReleaseMode)  
        router := gin.Default()
        router.GET("/", func(c *gin.Context) {
            c.String(http.StatusOK, "Hello World,Welcome To Go~")
        })
    
        router.POST("/User", func(c *gin.Context) {
            c.String(http.StatusOK, "This is User Post MOdel~")
        })
    
        router.GET("/User", func(c *gin.Context) {
            c.String(http.StatusOK, "This is User MOdel~")
        })
    
        //url route with ':' to match 
        router.GET("/user/:name",func (c *gin.Context)  {
            name := c.Param("name")
            c.String(http.StatusOK,"Hello %s",name)
        })
    
        //URL route with '*' to match more 
        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)
        })
    
    
        // Restful-Get with qps 
        router.GET("/leon0204", func(c *gin.Context) {
            firstname := c.DefaultQuery("firstname", "Guest")
            lastname := c.Query("lastname")
    
            c.String(http.StatusOK, "Hello %s %s", firstname, lastname)
        })
    
        // Restful-Post with qps 
    
        // res 
        /* { "message": "back from post", "nick": "默认Nickname", "status": { "status": "ok", "status_code": 200 } } */
    
        router.POST("/leonPost",func (c *gin.Context)  {
            message:=c.PostForm("message")
            nick:= c.DefaultPostForm("nick","默认Nickname")
    
            c.JSON(http.StatusOK,gin.H {
                "status": gin.H{
                    "status_code":http.StatusOK,
                    "status": "ok",
                },
                "message":message,
                "nick":nick,
            })
        })
    
        // qps & urlParams  请求体和效果见下图
        router.PUT("/PostAll", 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 \n", id, page, name, message)
            c.JSON(http.StatusOK, gin.H{
                "status_code": http.StatusOK,
            })
        })
    
    
    
    
    
    
        router.Run(":8005")
    }
