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
