Mergo: merging Go structs and maps since 2013
译文：Mergo:自2013年起合并Go structs 和 maps
文档
安装
go get github.com/imdario/mergo
示例
package main
import (
"fmt"
"github.com/imdario/mergo"
type Student struct {
Name string
Age int
// 小写的
email string
// struct 转 map
func structToMap() {
student := Student{
Name: "Tom",
Age: 23,
email: "123@qq.com",
var m = make(map[string]interface{})
mergo.Map(&m, student)
fmt.Printf("m: %v\n", m)
// m: map[age:23 name:Tom]
// map 转 struct
func mapToStruct() {
var m = make(map[string]interface{})
m["name"] = "Tom"
m["age"] = 23
m["email"] = "123@qq.com"
student := Student{}
mergo.Map(&student, m)
fmt.Printf("student: %v\n", student)
// student: {Tom 23 }
func main() {
structToMap()
mapToStruct()
注意事项：
-
mergo 不会复制非导出字段
-
map 使用时候，对应的key字段默认是小写的
-
mergo 可以
嵌套
赋值

好用的map-struct转换库 mergo
