Symfony 2-加载Web调试工具栏时发生错误（404：未找到） [英] Symfony 2 - An error occurred while loading the web debug toolbar (404: Not Found)

问题描述

由于更新了symfony 2.2，因此web调试工具栏不再加载到app_dev.php中。

Since the update to symfony 2.2, the web debug toolbar is no longer loaded in app_dev.php.

我收到以下错误消息：

An error occurred while loading the web debug toolbar (404: Not Found).
Do you want to open the profiler?

在prod.log中，我得到以下信息：

In the prod.log I get the following:

request.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No route found for "GET /_profiler/84fb75cc3ffd5435474ebe4250e01fac2cdf49c1"" at /httpdocs/project/app/cache/prod/classes.php line 3597 [] []

request.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No route found for "GET /_wdt/452d5b4aa2dd9388285fa1c286d5c54218029c71"" at /httpdocs/priject/app/cache/prod/classes.php line 3597 [] []

我已经多次清除了缓存：）

I have cleared the cache several times :)

有趣的是，在/app_dev.php中，页面上的所有链接都没有

Interesting is the fact that in /app_dev.php all links on the page no longer links to /app_dev.php.

包括配置文件（/ _profiler / 5fdc27cb82c4e9e426b3ab27377deb0b760fdca2）
，当我手动修改url并将app_dev.php添加到网址，分析器会正确加载。

including the profile (/_profiler/5fdc27cb82c4e9e426b3ab27377deb0b760fdca2) when i modify the url manually, and add the app_dev.php to the url, the profiler loads correctly.

routing_dev.yml：

routing_dev.yml:

_assetic:
    resource: .
    type:     assetic

_wdt:
    resource: "@WebProfilerBundle/Resources/config/routing/wdt.xml"
    prefix:   /_wdt

_profiler:
    resource: "@WebProfilerBundle/Resources/config/routing/profiler.xml"
    prefix:   /_profiler

_configurator:
    resource: "@SensioDistributionBundle/Resources/config/routing/webconfigurator.xml"
    prefix:   /_configurator

_main:
    resource: routing.yml

我将不胜感激。

更新I：config_dev.yml

UPDATE I: config_dev.yml

imports:
    - { resource: config.yml }

framework:
    router:   { resource: "%kernel.root_dir%/config/routing_dev.yml" }
    profiler: { only_exceptions: false }

web_profiler:
    toolbar: true
    intercept_redirects: false

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        firephp:
            type:  firephp
            level: info
        chromephp:
            type:  chromephp
            level: info

assetic:
    use_controller: true

更新II：AppKernel.php

UPDATE II: AppKernel.php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new JMS\AopBundle\JMSAopBundle(),
            new JMS\DiExtraBundle\JMSDiExtraBundle($this),
            new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
            new myProject\MyBundle\myBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new myProject\MyBackendBundle\myBackendBundle(),
       );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }
}

更新III：.htaccess

Update III: .htaccess

DirectoryIndex app.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(/(.*)|$) %{CONTEXT_PREFIX}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)(.+)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteRule .? %{ENV:BASE}app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /app.php/
    </IfModule>
</IfModule>

更新：我发现了错误，这是错误的（旧）在模板中呈现标记。 ：（

UPDATE: I have found the error, it was a wrong (old) render tag in a template. :(

推荐答案

我遇到了这个问题同样，请尝试注意您的.htaccess并使它看起来像这样：

I had this problem too, try to pay attention to your .htaccess and make it look like this:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app_dev.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]    ##### this is the part that you should tweak, have the .htaccess point the request to app_dev.php, since the routing.yml is empty initially
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]
    RewriteRule .? %{ENV:BASE}/app_dev.php [L]        ##### this is the part that you should tweak, have the .htaccess point the request to app_dev.php, since the routing.yml is empty initially
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the startpage to the front controller explicitly so that the website
        # and the generated links can still be used.
        RedirectMatch 302 ^/$ /app.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>
