Symfony 3.4：在prod环境中启用调试工具栏

Question

我正在使用Symfony 3.4，当我托管我的项目时，我遇到了一个Route问题，所以我必须调试它但是当我将 /app_dev.php 添加到我的域名时我收到一个错误：

You are not allowed to access this file. Check app_dev.php for more information.

Symfony是否会通过简单的配置阻止prod的调试工具？

我尝试过这个解决方案，但它并不适用于我：

我已完成所有这些更改，但工具栏尚未启用：

的应用程序/ AppKernel.php：

public function registerBundles()
    {
        $bundles = [
            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 Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new AppBundle\AppBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new MyVendorFOSUserBundle\MyVendorFOSUserBundle(),
        ];

    +        $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
    +        $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
    +        $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
    +
             if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
                 $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
                 $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();

的应用程序/配置/ config.yml：

 parameters:
     locale: en

+web_profiler:
+    toolbar: true

的应用程序/配置/ routing.yml中：

+
+_wdt:
+    resource: '@WebProfilerBundle/Resources/config/routing/wdt.xml'
+    prefix: /_wdt
+
+_profiler:
+    resource: '@WebProfilerBundle/Resources/config/routing/profiler.xml'
+    prefix: /_profiler
+
+_errors:
+    resource: '@TwigBundle/Resources/config/routing/errors.xml'
+    prefix: /_error

网/ app_dev.php：

//commenting this lines:
+
+// if (isset($_SERVER['HTTP_CLIENT_IP'])
+//     || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
+//     || !(in_array(@$_SERVER['REMOTE_ADDR'], ['127.0.0.1', '::1'], true) || PHP_SAPI === 'cli-server')
+// ) {
+//     header('HTTP/1.0 403 Forbidden');
+//     exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
+// }

composer.json：

"require": {
    "php": ">=5.5.9",
    "doctrine/doctrine-bundle": "^1.6",
    "doctrine/orm": "^2.5",
    "friendsofsymfony/user-bundle": "~2.0",
    "incenteev/composer-parameter-handler": "^2.0",
    "sensio/distribution-bundle": "^5.0.19",
    "sensio/framework-extra-bundle": "^5.0.0",
    "symfony/monolog-bundle": "^3.1.0",
    "symfony/polyfill-apcu": "^1.0",
    "symfony/swiftmailer-bundle": "^2.6.4",
    "symfony/symfony": "3.4.*",
    "twig/twig": "^1.0||^2.0",
+    "sensio/generator-bundle": "^3.0",
+    "symfony/phpunit-bridge": "^3.0"
},

1）我做死（$ this-＆gt; getEnvironement（））; =＆GT;刺

2）没有工具栏显示＆amp;当我尝试mydomain / app_dev.php时，我遇到了一个问题：

 ClassNotFoundException
Attempted to load class "SensioGeneratorBundle" from namespace "Sensio\Bundle\GeneratorBundle".
Did you forget a "use" statement for another namespace?

如果您已在生产中启用了探查器，而不是linking，那么需要运行应用程序app_dev.php，app.php应该可以正常运行。请确保composer.json require列在requre-dev下，而不是app_dev.php

如果出于任何原因您必须在服务器上使用// This check prevents access to debug front controllers that are deployed by accident to production servers. // Feel free to remove this, extend it, or make something more sophisticated. if (isset($_SERVER['HTTP_CLIENT_IP']) || isset($_SERVER['HTTP_X_FORWARDED_FOR']) || !(in_array(@$_SERVER['REMOTE_ADDR'], ['127.0.0.1', '::1'], true) || PHP_SAPI === 'cli-server') ) { header('HTTP/1.0 403 Forbidden'); exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.'); } ，那么您应该编辑该文件并更改其权限
