在技术开发中，捕获程序框架错误，是非常必要的一件事情，我们公司使用Yii2框架，简单说下Yii2的错误捕获处理
1 配置如下
其中errorHandler就是错误处理配置，执行ErrorController的actionError
'components' => [ "urlManager" => require (__DIR__ . '/router.php'), 'errorHandler' => [ 'errorAction' => 'error/error', ], ]
2 ErrorContrller代码示例
<?php
namespace blog\controllers;
use common\service\applog\ApplogService;
use Yii;
class ErrorController extends \yii\web\Controller{
public $enableCsrfValidation = false;
public function actionError() {
$code = 404;
$msg = 'Page Not Found';
$error = Yii::$app->errorHandler->exception;
if ($error) {
$code = $error->getCode();
$msg = $error->getMessage();
$file = $error->getFile();
$line = $error->getLine();
$err_msg = $msg . " [file: {$file}][line: {$line}][err code:$code.][url:{$_SERVER['REQUEST_URI']}][post:".http_build_query($_POST)."]";
ApplogService::add(Yii::$app->id,$err_msg);//我这里存入数据库
}
}
}1 配置如下，配置指定使用ErrorController(命令行应用和web应用还是有区别的)
'components' => [ "urlManager" => require (__DIR__ . '/router.php'), 'errorHandler' => [ 'class' => 'console\controllers\ErrorController' ] ]
2 ErrorController代码示例
<?php
namespace console\controllers;;
use common\service\applog\ApplogService;
use Yii;
use yii\base\ErrorException;
use yii\base\UserException;
use yii\helpers\Console;
use yii\console\Exception;
class ErrorController extends \yii\base\ErrorHandler{
protected function renderException($exception){
if ($exception instanceof Exception && ($exception instanceof UserException || !YII_DEBUG)) {
$message = $this->formatMessage($exception->getName() . ': ') . $exception->getMessage();
} else{
if ($exception instanceof Exception) {
$message = $this->formatMessage("Exception ({$exception->getName()})");
} elseif ($exception instanceof ErrorException) {
$message = $this->formatMessage($exception->getName());
} else {
$message = $this->formatMessage('Exception');
}
$message .= $this->formatMessage(" '" . get_class($exception) . "'", [Console::BOLD, Console::FG_BLUE])
. " with message " . $this->formatMessage("'{$exception->getMessage()}'", [Console::BOLD]) //. "\n"
. "\n\nin " . dirname($exception->getFile()) . DIRECTORY_SEPARATOR . $this->formatMessage(basename($exception->getFile()), [Console::BOLD])
. ':' . $this->formatMessage($exception->getLine(), [Console::BOLD, Console::FG_YELLOW]) . "\n";
if ($exception instanceof \yii\db\Exception && !empty($exception->errorInfo)) {
$message .= "\n" . $this->formatMessage("Error Info:\n", [Console::BOLD]) . print_r($exception->errorInfo, true);
}
$message .= "\n" . $this->formatMessage("Stack trace:\n", [Console::BOLD]) . $exception->getTraceAsString();
}
ApplogService::add(Yii::$app->id,$message);//存到数据库中
if (PHP_SAPI === 'cli') {
Console::stderr($message . "\n");
} else {
echo $message . "\n";
}
}
protected function formatMessage($message, $format = [Console::FG_RED, Console::BOLD]){
$stream = (PHP_SAPI === 'cli') ? \STDERR : \STDOUT;
// try controller first to allow check for --color switch
if (Yii::$app->controller instanceof \yii\console\Controller && Yii::$app->controller->isColorEnabled($stream)
|| Yii::$app instanceof \yii\console\Application && Console::streamSupportsAnsiColors($stream)) {
$message = Console::ansiFormat($message, $format);
}
return $message;
}
}对比下 命令行应用 和 web应用，ErrorController继承的不一样，并且实现的方法也不一样的
