Question

我希望在我的Symfony2应用程序中发生不良事件时收到警报。现在我只是在日志中查找ERROR。不幸的是，“HTTP 404 - 找不到文件”（NotFoundHttpException）被记录为错误，“HTTP 403 - 禁止”（AccessDeniedHttpException）。

这不保证错误;这些应该是警告。如何将这些日志设置为不太严重的级别？

示例错误：

[2012-07-02 16:58:21] request.ERROR: Symfony\Component\HttpKernel\Exception\NotFoundHttpException: No route found for "GET /foo" (uncaught exception) at /home/user/Symfony2_v2.0.12/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/EventListener/RouterListener.php line 83 [] []

Answer 1

我找到了有用的东西。 Symfony2 internals doc on the kernel.exeption event提到可以对事件设置响应，GetResponseForExceptionEvent docs说

此事件的传播会立即停止响应设定。

我拼凑了一个看起来像我想要的听众：

<?php

namespace Acme\DemoBundle\Listener;

use Symfony\Component\EventDispatcher\EventDispatcher;
use Symfony\Component\HttpKernel\Log\LoggerInterface;
use Symfony\Component\EventDispatcher\Event;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent;

class ExceptionLoggingListener {
  private $logger;

  public function __construct(LoggerInterface $logger) {
    $this->logger = $logger;
  }

  public function onKernelException(GetResponseForExceptionEvent $event) {
    if(!$event) {
      $this->logger->err("Unknown kernel.exception in ".__CLASS__);
      return;
    }
    $notFoundException = '\Symfony\Component\HttpKernel\Exception\NotFoundHttpException';

    $e = $event->getException();
    $type = get_class($e);
    if ($e instanceof $notFoundException) {
      $this->logger->info($e->getMessage());
      $response = new Response(Response::$statusTexts[404], 404);
      $event->setResponse($response);
      return;
    }

    $accessDeniedException = '\Symfony\Component\HttpKernel\Exception\AccessDeniedHttpException';
    if ($e instanceof $accessDeniedException) {
      $this->logger->info($e->getMessage());
      $response = new Response(Response::$statusTexts[403], 403);
      $event->setResponse($response);
      return;
    }
    $this->logger->err("kernel.exception of type $type. Message: '".$e->getMessage()."'\nFile: ".$e->getFile().", line ".$e->getLine()."\nTrace: ".$e->getTraceAsString());
  }

}

这是一种代码较少的方式：）

<强> 1。扩展Symfonys ExceptionListner类并覆盖日志记录方法：

<?php

use Symfony\Component\HttpKernel\EventListener\ExceptionListener as BaseListener;
use Symfony\Component\HttpKernel\Exception\HttpExceptionInterface;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;


class ExceptionListener extends BaseListener
{

    /**
     * Logs an exception.
     *
     * @param \Exception $exception The original \Exception instance
     * @param string     $message   The error message to log
     * @param Boolean    $original  False when the handling of the exception thrown another exception
     */
    protected function logException(\Exception $exception, $message, $original = true)
    {
        $isCritical = !$exception instanceof HttpExceptionInterface || $exception->getStatusCode() >= 500;

        if (null !== $this->logger) {
            if ($isCritical) {
                $this->logger->critical($message);
            } else {

                if ($exception instanceof NotFoundHttpException) {
                    $this->logger->info($message);
                } else {
                    $this->logger->error($message);
                }
            }
        } elseif (!$original || $isCritical) {
            error_log($message);
        }
    }
}

parameters:
    twig.exception_listener.class: "MyBundle\EventListener\ExceptionListener"

Answer 3

只需在您的配置中添加excluded_404s：

monolog:
    handlers:
        main:
            type:         fingers_crossed
            action_level: error
            handler:      nested
            excluded_404s:
                - ^/
        nested:
            type:  stream
            path:  "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug

请参阅http://symfony.com/doc/current/logging/monolog_regex_based_excludes.html以获取参考资料

Answer 4

基于Tarjei答案的Symfony 5解决方案：

创建一个覆盖Symfony ErrorListener的新ErrorListener。

App \ EventListener \ ErrorListener.php

services:
    App\EventListener\ErrorListener: '@exception_listener'

    exception_listener:
        autowire: false
        class: App\EventListener\ErrorListener
        arguments:
            $controller: '%kernel.error_controller%'
            $logger: '@logger'
            $debug: '%kernel.debug%'

services.yaml

"Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[JIRA.Objects.DeletedWorkLog]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'values', line 1, position 10."

Answer 5

您还可以使用错误级别活动策略（实际上Symfony的内置404错误排除是使用此操作完成的，所以我想这是一种正确的方法）。

<强> config.yml

monolog:
    handlers:
        main:
            type: fingers_crossed
            handler: loggly
            activation_strategy: 'mybundle.monolog.fingers_crossed.activation_strategy'
        loggly:
            type: loggly
            token: %loggly_token%
            level: error
            tag: %loggly_tag%

services.yml （请注意，此处设置了操作级别，而不是在config.yml中设置）

services:
    mybundle.monolog.fingers_crossed.activation_strategy:
        class: MyBundle\Handler\FingersCrossed\ErrorLevelActivationStrategy
        arguments:
            - '@request_stack'
            - 'error'

ErrorLevelActivationStrategy.php

<?php
namespace MyBundle\Handler\FingersCrossed;

use Monolog\Handler\FingersCrossed\ErrorLevelActivationStrategy as BaseErrorLevelActivationStrategy;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Symfony\Component\HttpFoundation\RequestStack;

/**
 * Activation strategy that ignores client errors (4xx)
 */
class ErrorLevelActivationStrategy extends BaseErrorLevelActivationStrategy
{
    protected $requestStack;
    public function __construct(RequestStack $requestStack, $actionLevel)
    {
        parent::__construct($actionLevel);
        $this->requestStack = $requestStack;
    }
    /**
     * {@inheritdoc}
     */
    public function isHandlerActivated(array $record)
    {
        $isActivated = parent::isHandlerActivated($record);
        if (
            $isActivated
            && isset($record['context']['exception'])
            && $record['context']['exception'] instanceof HttpException
            && $record['context']['exception']->getStatusCode() >= 400
            && $record['context']['exception']->getStatusCode() <= 499
            && ($request = $this->requestStack->getMasterRequest())
        ) {
            $isActivated = false;
        }
        return $isActivated;
    }
}

在Symfony 3.3中首选此参数，而不是exclude_404s参数。

app / config / services.yml

exception_listener:
    class: AppBundle\Listener\ExceptionListener
    arguments: ["@logger", "@templating"]
    tags:
        - { name: kernel.event_listener, event: kernel.exception}

src / AppBundle / Listener / ExceptionListener.php

<?php

namespace AppBundle\Listener;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent;
use Symfony\Bridge\Monolog\Logger;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Symfony\Component\Templating\EngineInterface;

class ExceptionListener
{
    private $logger;
    private $templateEngine;

    public function __construct(Logger $logger, EngineInterface $templateEngine)
    {
        $this->logger = $logger;
        $this->templateEngine = $templateEngine;
    }

    public function onKernelException(GetResponseForExceptionEvent $event)
    {
        $exception = $event->getException();
        if ($exception instanceof NotFoundHttpException)
        {
            $this->logger->info($exception->getMessage());

            // default twig error app/config/Resources/TwigBundle/views/Exception/error.html.twig
            $response = $this->templateEngine->render('TwigBundle:Exception:error.html.twig');

            $event->setResponse(new Response($response));
        }
    }
}
