json标签

  1. type UserInfo struct {
  2.     Name     string `json:"name"`
  3.     Email    string `json:"email"`
  4.     Password string `json:"password"`
  5. }

结构体到JSON

  1. marshal, _ := json.Marshal(&user1)

JSON到结构体

  1. _ = json.Unmarshal([]byte(rawJson), &user2)

示例代码

  1. package main
  3. import (
  4.     "encoding/json"
  5.     "fmt"
  6. )
  8. type UserInfo struct {
  9.     Name     string `json:"name"`
  10.     Email    string `json:"email"`
  11.     Password string `json:"password"`
  12. }
  14. func main() {
  15.     user1 := UserInfo{
  16.         Name:     "luckFang",
  17.         Email:    "1318659507@qq.com",
  18.         Password: "123456",
  19.     }
  21.     // 生成json
  22.     marshal, _ := json.Marshal(&user1)
  23.     rawJson := fmt.Sprintf("%s", marshal)
  24.     fmt.Println(rawJson)
  25.     var user2 UserInfo
  27.     // 解析json到结构体
  28.     _ = json.Unmarshal([]byte(rawJson), &user2)
  29.     fmt.Printf("%#v\n", user2)
  31. }
  1. {"name":"luckFang","email":"1318659507@qq.com","password":"123456"}
  2. main.UserInfo{Name:"luckFang", Email:"1318659507@qq.com", Password:"123456"}
