重写Handle的render方法,实现自定义异常消息-----------------------------------------------------------------------
首先要在config.php里面配置
// 异常处理handle类 留空使用 hinkexceptionHandle
'exception_handle' => '\app\common\exception\ExceptionHandler',
ExceptionHandler.php
<?php
namespace appcommonexception;
use thinkexceptionHandle;
use thinkLog;
use Exception;
/**
* 重写Handle的render方法,实现自定义异常消息
* Class ExceptionHandler
* @package appcommonlibraryexception
*/
class ExceptionHandler extends Handle
{
private $code;
private $message;
/**
* 输出异常信息
* @param Exception $e
* @return hinkResponse| hink
esponseJson
*/
public function render(Exception $e)
{
if ($e instanceof BaseException) {
$this->code = $e->code;
$this->message = $e->message;
} else {
if (config('app_debug')) {
return parent::render($e);
}
$this->code = 0;
$this->message = $e->getMessage() ?: '很抱歉,服务器内部错误';
$this->recordErrorLog($e);
}
return json(['msg' => $this->message, 'code' => $this->code]);
}
/**
* 将异常写入日志
* @param Exception $e
*/
private function recordErrorLog(Exception $e)
{
Log::record($e->getMessage(), 'error');
Log::record($e->getTraceAsString(), 'error');
}
}
自定义异常类的基类---------------------------------------------------------------------------------------------
BaseException.php
<?php
namespace appcommonexception;
use thinkException;
/**
* Class BaseException
* 自定义异常类的基类
*/
class BaseException extends Exception
{
public $code = 0;
public $message = 'invalid parameters';
/**
* 构造函数,接收一个关联数组
* @param array $params 关联数组只应包含code、msg,且不应该是空值
*/
public function __construct($params = [])
{
if (!is_array($params)) {
return;
}
if (array_key_exists('code', $params)) {
$this->code = $params['code'];
}
if (array_key_exists('msg', $params)) {
$this->message = $params['msg'];
}
}
}
抛出异常时显示如下
