package main

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

type User struct {
	Id int 				`json:"id"`
	Name string			`json:"name"`
	Age int				`json:"age"`
}

func main() {
	router := gin.Default()
	router.GET("/users", func(c *gin.Context) {
		c.JSON(200, true)						//true
		c.JSON(200, gin.H{"msg" : "hello world!"})	//{"msg":"hello world!"}
		c.JSON(200, &User{Id: 1, Name:"卷毛狒狒", Age:20})  //{"id":1,"name":"卷毛狒狒","age":20}
	})
	router.Run(":8080")
}

//{"user":{"age":"20","name":"juanmaofeifei"}}
