Go 
简介 go 遍历结构体

代码如下

package main

import (
    "fmt"
    "reflect"
)

type Tags struct {
    ID   int
    Name string
}

func main() {
    var tag Tags
    tag.ID = 1
    tag.Name = "魏花花"

    var typeInfo = reflect.TypeOf(tag)
    var valInfo = reflect.ValueOf(tag)
    num := typeInfo.NumField()
    for i := 0; i < num; i++ {
        key := typeInfo.Field(i).Name
        val := valInfo.Field(i).Interface()
        fmt.Println(i)
        fmt.Printf("%T --- %v\n", key, key)
        fmt.Printf("%T --- %v\n", val, val)
    }
}

string —- ID
int —- 1
