通过反射获取结构体对象属性及其值

package main

import (
    "fmt"
    "reflect"
)

type A struct {
    a interface{}
    B bool
}

func main() {
    a := A{}

    fmt.Printf("a:%+v\n", a)

    refType := reflect.TypeOf(a)
    if refType.Kind() != reflect.Struct {
        fmt.Println("Not a structure type.")
    }

    for i := 0; i < refType.NumField(); i++ {
        fmt.Printf("file:%+v,\t", refType.Field(i).Name)

        v := reflect.ValueOf(a)
        val := v.FieldByName(refType.Field(i).Name)
        fmt.Printf("value:%+v\n", val)
    }
}

// output:
// a:{a: B:false}
// file:a, value:
// file:B, value:false
