            $result = [

                'message' => $myException->getMessage(),
                'data' => null

异常类（只需要继承基础的异常类即可）

<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2018/12/8 0008
 * Time: 14:38
 */

namespace app\librarys;


class MyException extends \Exception
{

}

 

可以在任意地方使用，不需要再写返回值，自动返回。

throw new MyException('错误信息');
