Go-JSon反序列化

指定结构体的tag标签

package main

import (
	"encoding/json"
	"fmt"
)

type Monster struct {
	Name     string `json:"moster_name"`
	Age      int    `json:"moster_age"`
	Birthday string
	Sal      float64
	Skill    string
}

func testStruct() {
	monster := Monster{
		Name:     "牛魔王",
		Age:      500,
		Birthday: "2011-11-11",
		Sal:      8000.0,
		Skill:    "牛魔拳",
	}
	//序列化
	data, err := json.Marshal(&monster)
	if err != nil {
		fmt.Printf("序列化失败err=%v", err)
	}
	fmt.Printf("monster序列化后=%v", string(data))
}

func main() {
	testStruct()
