golang学习5，glang的web的restful接口

1. //返回json
   r.GET("/getJson", controller.GetUserInfo)
   package main

import (
/"net/http"/
"gin/src/main/controller"
"github.com/gin-gonic/gin"
)

func main() {
r := gin.Default()

r.GET("/get", func(ctx *gin.Context) {
    ctx.String(200/*http.StatusOK*/, "hello word golang-web!")
})

r.POST("/user/post", func(ctx *gin.Context) {
    ctx.String(200, "这是一个post请求！")
})

r.PUT("/user/put", func(ctx *gin.Context) {
    ctx.String(200, "这是一个put请求！")
})

r.DELETE("/user/delete", func(ctx *gin.Context) {
    ctx.String(200, "这是一个delete请求！")
})


//返回json
r.GET("/getJson", controller.GetUserInfo)




r.Run(":9999")

}
2.
package controller

import "github.com/gin-gonic/gin"

func GetUserInfo(c *gin.Context) {
ReturnSucess(c, 200, "sucess", "user info" , 1)

}
3.
package controller

import "github.com/gin-gonic/gin"

type JsonStruct struct {
Code int //'json: "code"'
Msg interface{} //'json: "msg"'
Data interface{} //'json: "data"'
Count int64 //'json: "count"'
}

func ReturnSucess(c *gin.Context, code int , msg interface{}, data interface{}, count int64) {
json := &JsonStruct{Code: code, Msg: msg, Data: data, Count: count}
c.JSON(200, json)
}

func ReturnError(c *gin.Context, code int , msg interface{}, data interface{}, count int64) {
json := &JsonStruct{Code: code, Msg:msg, Data:data, Count:count}
c.JSON(200, json)
}
