5.json反序列化为结构体

json反序列化为结构体 ~~~ package main import ( "encoding/json" "fmt" ) type User struct { UserName string `json:"username"` NickName string `json:"nickname"` Age int Birthday string Sex string Email string Phone string } func testStruct() (ret string, err error) { user1 := &User{ UserName: "user1", NickName: "Murphy", Age: 18, Birthday: "2008/8/8", Sex: "男", Email: "taidou008@qq.com", Phone: "110", } data, err := json.Marshal(user1) if err != nil { err = fmt.Errorf("json.marshal failed, err:", err) return } ret = string(data) return } func test() { data, err := testStruct() if err != nil { fmt.Println("test struct failed, ", err) return } var user1 User err = json.Unmarshal([]byte(data), &user1) if err != nil { fmt.Println("Unmarshal failed, ", err) return } fmt.Println(user1) } func main() { test() fmt.Println("-----") } ~~~ 输出结果： ~~~ {user1 Murphy 18 2008/8/8 男 taidou008@qq.com 110} ----- ~~~
