golang如何使用struct name作为映射键

package main

import (
    "fmt"
    "reflect"
)

type Person struct {
    Name   string
    Age    int
    Gender string
}

func main() {
    p := Person{
        Name:   "John",
        Age:    30,
        Gender: "Male",
    }

    // 获取struct的类型信息
    t := reflect.TypeOf(p)

    // 获取字段的值并作为映射键
    m := make(map[string]interface{})
    for i := 0; i < t.NumField(); i++ {
        field := t.Field(i)
        value := reflect.ValueOf(p).FieldByName(field.Name).Interface()
        key := field.Name
        m[key] = value
    }

    // 打印映射结果
    for key, value := range m {
        fmt.Printf("%s: %v\n", key, value)
    }
}

Name: John
Age: 30
Gender: Male
