import (    "github.com/gin-gonic/gin"    "net/http"    "github.com/sirupsen/logrus")// 1、最简单ginfunc GinSample(){    engine := gin.Default()    engine.Any("/",func(context *gin.Context){        context.String(http.StatusOK,"hello world")    })    engine.Run(":9025")}// 2、gin各种方法func GinFunc(){    engine := gin.Default()    // get    engine.GET("/get",func(context *gin.Context){        context.JSON(http.StatusOK,gin.H{
    "message":"hello world","status":"done"})    })    // put    engine.PUT("/put",func(context *gin.Context){        context.String(http.StatusOK,"put ok")    })    // post    engine.POST("/post",nil)    //...    engine.Run(":9025")}// 3、gin 解析入参func GinGetParam(){    engine := gin.Default()    engine.GET("/get/:name/*action",func(context *gin.Context){        name := context.Param("Guest")        action := context.Param("action")        context.String(http.StatusOK,"welcome " + name + action)    })    engine.Run(":9025")}// 4、gin 路由组func GinGroup(){    engine := gin.Default()    v1 := engine.Group("/v1")    {        v1.GET("/get",nil) // handlers待实现        v1.POST("post",nil)    }    v2 := engine.Group("/v2")    {        v2.GET("/get",nil)        v2.POST("/post",nil)    }    engine.Run(":9025")}// 5、中间件func Middle() {    router := gin.Default()    // 注册一个路由，使用了 middleware1，middleware2 两个中间件    router.GET("/someGet", middleware1, middleware2, handler)    // 默认绑定 :8080    router.Run()}func handler(c *gin.Context) {    logrus.Println("exec handler")}func middleware1(c *gin.Context){    // do something    c.Next()}func middleware2(c *gin.Context){    // do something    c.Next()}
