namespace common\component\exception;
/**

* 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',
],效果如下：
