将struct转为map

package main

import (
    "fmt"
    "reflect"
    "time"
)

type User struct {
    Id        int64
    Username  string
    Password  string
    Logintime time.Time
}

func Struct2Map(obj interface{}) map[string]interface{} {
    t := reflect.TypeOf(obj)
    v := reflect.ValueOf(obj)

    var data = make(map[string]interface{})
    for i := 0; i < t.NumField(); i++ {
        data[t.Field(i).Name] = v.Field(i).Interface()
    }
    return data
}
func main() {
    user := User{5, "zhangsan", "pwd", time.Now()}
    data := Struct2Map(user)
    fmt.Println(data)
}
