Elem反射操作结构体 ~~~ package main import ( "fmt" "reflect" ) type Student struct { Name string Age int Score float32 } func (s Student) Print() { fmt.Println(s) } func TestStruct(a interface{}) { val := reflect.ValueOf(a) kd := val.Kind() fmt.Println(val, kd) if kd != reflect.Ptr && val.Elem().Kind() == reflect.Struct { fmt.Println("expect struct") return } //获取字段数量 fields := val.Elem().NumField() fmt.Printf("struct has %d field\n", fields) //获取字段的类型 for i := 0; i < fields; i++ { fmt.Printf("%d %v\n", i, val.Elem().Field(i).Kind()) } //获取方法数量 methods := val.NumMethod() fmt.Printf("struct has %d methods\n", methods) //反射调用的Print方法 var params []reflect.Value val.Elem().Method(0).Call(params) } func main() { var a Student = Student{ Name: "stu01", Age: 18, Score: 92.8, } TestStruct(&a) // fmt.Println(a) } ~~~ 输出结果: ~~~ &{stu01 18 92.8} ptr struct has 3 field 0 string 1 int 2 float32 struct has 2 methods {stu01 18 92.8} ~~~
