Learn the encapsulation of thinkphp5 commonly used api exception class ApiException

Encapsulate ApiException.php exception class

<?php

namespace app\common\lib\exception;

//引用异常类
use think\Exception;


//继承异常类
class ApiException extends Exception
{
    
    
    //自定义http状态码
    public $message = '';
    public $httpCode = 400;
    public $code = 0;

    /*
     * 渲染抛出异常的状态码和信息
     */
    public function __construct($message = "", $httpCode = 0, $code = 0)
    {
    
    
        $this->message = $message;
        $this->httpCode = $httpCode?:400;
        $this->code = $code;
    }
}

Call the exception class to throw an exception

Where an exception needs to be thrown, quote

//一定要优先引用后在调用
use app\common\lib\exception\ApiException;


 //在方法中调用
$category_ay = [];
if (!$category_ay) {
    
    
   throw new ApiException('暂无分类列表！');
}


//验证请求的app客户端是否合法
        if (!in_array($header['apptype'], config('app.apptypes'))) {
    
    
            throw new ApiException('客户端不合法！', 400);
        }
