Go 结构体与map互转

我们可以利用结构体，map都可以转json的特性来实现

func StructToMap(input interface{}, output interface{}) {
    str, err := json.Marshal(input)
    if err != nil {
        fmt.Println("json.Marshal err", err)
        return
    }
    _ = json.Unmarshal([]byte(str),&output)
}

type User struct {
    Name string
    Age int
}
func main() {
    user := User{
        Name:"胖大叔",
        Age:18,
    }
    var UserMap map[string]interface{}
    //结构体转map
    StructToMap(user, &UserMap)
    fmt.Println(UserMap)
    //map转struct
    StructToMap(UserMap, &user)
    fmt.Println(user)
}
