golang 反射用法,做个笔记.
package main
import (
"fmt"
"reflect"
)
type roles struct {
roleId int
roleName string
}
type User struct {
Name string
Age int
Email string
NickName string
Telphone int
Roles roles
}
func main() {
u := User{Name: "Name",Age: 30,Email: "xxxx@afanty3d.com",NickName: "omni360",Telphone: xxxxx,Roles: roles{roleId: 1001,roleName: "administrator"}}
fmt.Println(u)
Info(u)
}
func Info(o interface{}) {
t := reflect.TypeOf(o)
fmt.Println("Type:",t.Name())
v := reflect.ValueOf(o)
fmt.Println("Fileds:")
for i := 0; i < t.NumField(); i++ {
f := t.Field(i)
val := v.Field(i).Interface()
fmt.Printf("%6s : %v %v\n",f.Name,f.Type,val)
}
}
