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)
