beego实现json消息的收发

1、修改beego代码

1、运行解析post的json数据
root@instance-x8rtph4n:/home/go/src/myproject# more conf/app.conf 
appname = myproject
httpport = 8080
runmode = dev
copyrequestbody = true
root@instance-x8rtph4n:/home/go/src/myproject#

2、创建user的处理控制器
root@instance-x8rtph4n:/home/go/src/myproject# more controllers/user.go 
package controllers

import (
        "fmt"
        "encoding/json"
        "github.com/astaxie/beego"
)

type UserController struct {
        beego.Controller
}

type JSONStruct struct {
    Code int  `json:"code"`
    Msg  string  `json:"msg"`
}

func (c *UserController) Get() {
        c.Ctx.ResponseWriter.Header().Set("Access-Control-Allow-Origin", "*")  //允许跨域
        //c.Data["json"] = map[string]interface{}{"success": 0, "message": "111"}
        c.Data["json"] = &JSONStruct{007, "hello"}
        c.ServeJSON()
       // c.Ctx.WriteString("hello 1111")
        return
}

func (c *UserController) Post() {
        var user JSONStruct
        data := c.Ctx.Input.RequestBody
        //json数据封装到user对象中
        err := json.Unmarshal(data, &user)
        if err != nil {
                fmt.Println("json.Unmarshal is err:", err.Error())
        }
        fmt.Println(user)
        c.Ctx.WriteString(user.Msg)
}

3、定义路由
root@instance-x8rtph4n:/home/go/src/myproject# more routers/router.go 
package routers

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

func init() {
    beego.Router("/", &controllers.MainController{})
    beego.Router("/user", &controllers.UserController{})
}
root@instance-x8rtph4n:/home/go/src/myproject#

4、运行服务端
bee run

2、postman实现post（数据需要自己修改）

3、使用ajax获取get消息
