beego框架返回json數據

一.routers路由

package routers

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

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

二.controllers邏輯

package controllers

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


type DataController struct {
    beego.Controller
}

type LIKE struct {
    Food string
    Watch string
    Listen string
}

type JSONS struct {
    //必須的大寫開頭
    Code string
    Msg  string
    User []string `json:"user_info"`//key重命名,最外面是反引號
    Like LIKE
}

func (c *DataController) Get() {
    data := &JSONS{"100", "獲取成功",
        []string{"maple","18"},LIKE{"蛋糕","電影","音樂"}}
    c.Data["json"] = data
    c.ServeJSON()
}

三.輸出顯示

{
  "Code": "100",
  "Msg": "獲取成功",
  "User": [
    "maple",
    "18"
  ],
  "Like": {
    "Food": "蛋糕",
    "Watch": "電影",
    "Listen": "音樂"
  }
}
