Symfony2网站未返回404错误

Question

如果我尝试访问网站上不存在的任何资源（如example.com/this/path/does/not/exist或example.com/images/fakeimage.jpg），它不会返回404错误。它只是在超时前挂起大约一分钟，同时将服务器上的CPU和RAM最大化。

我以为可能是.htaccess文件的问题，但它与默认的Symfony相同。

我另一个想法是它可能是我的Apache Vhost文件的问题，但我有另一个Symfony网站，使用相同的配置/不同的站点名称，没有任何问题运行。

我有点不知所措了。还有什么其他的想法可以看看？

--编辑-- 我在日志中找到了这个：

request.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No route found for "GET /this/is/not/a/path"" at /var/www/dev/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/EventListener/RouterListener.php line 176 {"exception":"[object] (Symfony\\Component\\HttpKernel\\Exception\\NotFoundHttpException(code: 0): No route found for \"GET /this/is/not/a/path\" at /var/www/dev/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/EventListener/RouterListener.php:176, Symfony\\Component\\Routing\\Exception\\ResourceNotFoundException(code: 0):  at /var/www/dev/app/cache/prod/appProdUrlMatcher.php:2209)"} []

接下来会有大约100个类似这样的：

[2016-08-22 15:26:10] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Security\Core\Exception\AuthenticationCredentialsNotFoundException: "The token storage contains no authentication token. One possible reason may be that there is no firewall configured for this URL." at /var/www/dev/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authorization/AuthorizationChecker.php line 57 {"exception":"[object] (Symfony\\Component\\Security\\Core\\Exception\\AuthenticationCredentialsNotFoundException(code: 0): The token storage contains no authentication token.

我看到有关Symfony中security.yml可能会涉及到此问题。以下内容可能有什么不妥之处吗？

好的，我找到了解决方法，虽然我怀疑其他人会因为跟我一样的原因而遇到这个问题。这篇帖子让我走上了解决之路。Symfony2 error 500 instead of 404 at production

我结合着这篇帖子和我得到的一些错误信息，发现几个月前当我第一次学习Symfony时，曾尝试在生产服务器上启用Symfony Profiler，我的config.yml文件中加入了以下内容：

profiler:
    matcher:
        service: app.super_admin_matcher

还有在AppBundle/Profiler/SuperAdminMatcher.php中：

<?php

namespace AppBundle\Profiler;

use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RequestMatcherInterface;

class SuperAdminMatcher implements RequestMatcherInterface
{
    protected $authorizationChecker;

    public function __construct(AuthorizationCheckerInterface $authorizationChecker)
    {
        $this->authorizationChecker = $authorizationChecker;
    }

    public function matches(Request $request)
    {
        return $this->authorizationChecker->isGranted('ROLE_SUPER_ADMIN');
    }
}

?>

一旦我删除了那段代码，因为现在我不需要它，一切又像魔术般地重新开始工作了。
