yii2如何自定义500错误

1、创建ErrorHandler，继承这个yii\base\ErrorHandler抽象类，然后定义这个父类中的抽象方法

<?phpnamespace common\component\exception;/** * User: szliugx@gmail.com * Date: 2016/9/20 * Time: 14:24 */use yii;use yii\base\ErrorHandler as BaseErrorHandler;use common\component\earlywarning\EarlyWarning;class ErrorHandler extends BaseErrorHandler{    public $errorView = '@app/views/errorHandler/error.php';    public function renderException($exception)    {        if(Yii::$app->request->getIsAjax()){            exit( json_encode( array('code' =>$exception->getCode(),'msg'  =>$exception->getMessage()) ));        }else{            //将500的代码，发送监控预警            if(!empty($exception->getCode()) && $exception->getCode() ==8){                $params = [];                $params['projectName'] = "oct-youban";                $params['level'] = 5;                $params['title'] = "500：".$exception->getMessage();                $params['value'] = $exception->getCode();                $params['message'] = $exception->getFile()."：".$exception->getLine();                $params['bizcode'] = 8;                $params['subcode'] = 8001;                EarlyWarning::WarninApi($params);            }            echo  Yii::$app->getView()->renderFile($this->errorView,['exception' => $exception,],$this);        }    }}

2、创建视图文件： @app/views/errorHandler/error.php

<?php/** * User: szliugx@gmail.com * Date: 2016/9/20 * Time: 15:23 */?><!DOCTYPE html><html><head>    <meta charset="UTF-8">    <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">    <meta name="apple-mobile-web-app-capable" content="yes">    <meta name="apple-mobile-web-app-status-bar-style" content="black">    <meta name="format-detection" content="telephone=no">    <meta http-equiv="Expires" content="-1">    <meta http-equiv="Cache-Control" content="no-cache">    <meta http-equiv="Pragma" content="no-cache">    <title><?php if(!empty($exception->getCode())&&($exception->getCode() == 8)){echo "出错啦";}else{ echo $exception->getMessage();}?></title>    <link href="/css/error.css" rel="stylesheet" 0="frontend\assets\AppAsset"></head><body><div>    <div class="status-icon icon-desk"></div>    <div>        <p><?php if(!empty($exception->getCode())&&($exception->getCode() == 8)){echo "出错啦";}else{ echo $exception->getMessage();}?></p>    </div></div></body></html>

3、修改应用的配置文件：@app/config/main.php

'errorHandler' => [            //'errorAction' => 'site/error',            'class' => 'common\component\exception\ErrorHandler',        ],

登录后复制

效果如下：
