[Go语言] golang如何获得一个变量的类型

fmt.Println(reflect.TypeOf(var))

func typeof(v interface{}) string {
  return fmt.Sprintf("%T", v)
}

func typeof(v interface{}) string {
  return reflect.TypeOf(v).String()
}

func typeof(v interface{}) string {
  switch v.(type) {
  case int:
    return "int"
  case float64:
    return "float64"
  //... etc
  default:
    return "unknown"
  }
}

fmt.Println(reflect.TypeOf(var))  
switch xxx.(type){
  case int:....
  case float32:...
  case float64:...
  case string:...
}
