beego框架返回json数据

一.routers路由

package routers

import (
    "mybeego/controllers"
    "github.com/astaxie/beego"
)

func init() {
    beego.Router("/data", &controllers.DataController{})
}

二.controllers逻辑

package controllers

import (
    "github.com/astaxie/beego"
)

type DataController struct {
    beego.Controller
}

type LIKE struct {
    Food string
    Watch string
    Listen string
}

type JSONS struct {
    //必须的大写开头
    Code string
    Msg  string
    User []string `json:"user_info"`//key重命名,最外面是反引号
    Like LIKE
}

func (c *DataController) Get() {
    data := &JSONS{"", "获取成功",
        []string{"maple",""},LIKE{"蛋糕","电影","音乐"}}
    c.Data["json"] = data
    c.ServeJSON()
}

三.输出显示

{
  "Code": "",
  "Msg": "获取成功",
  "User": [
    "maple",
    ""
  ],
  "Like": {
    "Food": "蛋糕",
    "Watch": "电影",
    "Listen": "音乐"
  }
}
