func Call(m map[string]interface{}, name string, params ...interface{}) ([]reflect.Value, error) {	f := reflect.ValueOf(m[name])	if len(params) != f.Type().NumIn() {		return nil, errors.New("the number of input params not match!")	}	in := make([]reflect.Value, len(params))	for k, v := range params {		in[k] = reflect.ValueOf(v)	}	return f.Call(in), nil}

 

使用：

func Test(a, b string) (string,error) {	return a +" "+ b,nil}

 

 

m := map[string]interface{}{"test":Test}	ret, err := Call(m, "test", "hello", "world")	if err != nil {		log.Fatalln("method invoke error:", err)	}	fmt.Println(ret)
