TP5 自定义异常类

TP5 异常处理 文档

先新建了一个异常处理接管的类。在application/lib/expection下创建
ExceptionHandler.php

<?php
namespace app\lib\exception;

use Exception;
use think\exception\Handle;

class ExceptionHandler extends Handle
{
    
    
    public $code;
    public $msg;
    public $errorCode;

    public function render(Exception $e){
    
    

        if ($e instanceof BaseException) {
    
    
            $this ->code = $e->code;
            $this ->msg = $e->msg;
            $this ->errorCode = $e->errorCode;
        }else{
    
    
            // debug开启，显示默认的异常
            if (config('app.app_debug')) return parent::render($e);

            $this ->code = 500;
            $this ->msg = '服务器异常';
            $this ->errorCode = '999';
        }

        $res = [
            'msg'=>$this->msg,
            'errorCode'=>$this->errorCode
        ];

        return json($res, $this->code);
    }
}

然后创建自定义异常BaseException.php 类继承 Exception

<?php
namespace app\lib\exception;
use Exception;

class BaseException extends Exception
{
    
    
    public $code = 500;
    public $msg = '异常';
    public $errorCode = 999;

    public function __construct($params = []){
    
    
        if (!is_array($params)) return;
        if (array_key_exists('code',$params))  $this->code = $params['code'];
        if (array_key_exists('msg',$params))  $this->msg = $params['msg'];
        if (array_key_exists('errorCode',$params))  $this->errorCode = $params['errorCode'];
    }
}

最后定义一个公共方法抛出异常

// 异常类输出函数
function TApiException($msg = '异常', $errorCode = 999, $code = 500){
    
    
    throw new \app\lib\exception\BaseException(['code'=>$code,'msg'=>$msg,'errorCode'=>$errorCode]);
}
