## 一、實例 ~~~ package main import ( "reflect" "fmt" ) //結構體 type User struct { Id int Name string Age int } type Boy struct { User Addr string } func main() { m := Boy{User{1,"zhangsan",20},"sz"} //獲取對象信息 t := reflect.TypeOf(m) //#號會把反射的結構體的詳情打印 fmt.Printf("%#v\n",t.Field(0)) } ~~~ 打印結果： reflect.StructField{Name:"User", PkgPath:"", Type:(*reflect.rtype)(0x8ed280), Tag:"", Offset:0x0, Index:[]int{0}, Anonymous:true}
