Symfony 4:加载Web调试工具栏时发生错误

Question

我在CentOS工作.

我按照教程:

• http://symfony.com/doc/current/best_practices/creating-the-project.html

• https://symfony.com/doc/current/page_creation.html

当我使用Apache时,我也遵循了这个页面:

• https://symfony.com/doc/current/setup/web_server_configuration.html

我制作了默认控制器和默认模板.使用此控制器(/),我得到以下错误(在调试工具栏中):

An error occurred while loading the web debug toolbar. Open the web profiler.

当我点击链接:"打开web profiler"时,我可以看到Apache响应:

Not Found
The requested URL /_profiler/177403 was not found on this server.

在chrome检查器中,我可以看到:GET http://172.31.18.7/_wdt/177403 404(未找到)

这是我的composer.json的有趣部分:

    "require": {
        "php": "^7.1.3",
        "ext-iconv": "*",
        "doctrine/doctrine-fixtures-bundle": "^3.0",
        "sensio/framework-extra-bundle": "^5.1",
        "sonata-project/admin-bundle": "^3.35",
        "sonata-project/doctrine-orm-admin-bundle": "^3.6",
        "symfony/apache-pack": "^1.0",
        "symfony/console": "^4.0",
        "symfony/flex": "^1.0",
        "symfony/framework-bundle": "^4.0",
        "symfony/lts": "^4@dev",
        "symfony/maker-bundle": "^1.4",
        "symfony/orm-pack": "^1.0",
        "symfony/requirements-checker": "^1.1",
        "symfony/security-bundle": "^4.0",
        "symfony/twig-bundle": "^4.0",
        "symfony/validator": "^4.0",
        "symfony/yaml": "^4.0"
    },
    "require-dev": {
        "sensiolabs/security-checker": "^4.1",
        "symfony/dotenv": "^4.0",
        "symfony/web-profiler-bundle": "^4.0"
    },

我的httpd.conf:

<VirtualHost *:80>
DocumentRoot /var/www/html/elora/public
ServerName eloradev
ServerAlias www.elora.dev
DirectoryIndex index.php

<Directory "elora/public">
    AllowOverride all
    Order Allow,Deny
    Deny from all
    Allow from 127.0.0.1
    Allow from ::1
    Allow from localhost
</Directory>

<Directory elora>
    Options FollowSymlinks
</Directory>    

ErrorLog /var/apache/logs/error.log
CustomLog /var/apache/logs/access.log combined  

</VirtualHost>

而我的.htaccess:

DirectoryIndex index.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]

    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 307 ^/$ /index.php/
    </IfModule>
</IfModule>

并且,为了完成,我的/ lucky/number(https://symfony.com/doc/current/page_creation.html)会引发apache消息:

Not Found
The requested URL /lucky/number was not found on this server.

看起来路由组件不起作用.

路由器规则(debug:router):

-------------------------- -------- -------- ------ -------------------
Name                       Method   Scheme   Host   Path
-------------------------- -------- -------- ------ ----------------------- 
  app_homepage               ANY      ANY      ANY    /
  app_lucky                  ANY      ANY      ANY    /lucky
  app_lucky_number           ANY      ANY      ANY    /lucky/number
  _twig_error_test           ANY      ANY      ANY    /_error/{code}.{_format}
  _wdt                       ANY      ANY      ANY    /_wdt/{token}
  _profiler_home             ANY      ANY      ANY    /_profiler/

  _profiler                  ANY      ANY      ANY    /_profiler/{token}
  _profiler_router           ANY      ANY      ANY    /_profiler/{token}/router
  _profiler_exception        ANY      ANY      ANY    /_profiler/{token}/exception
  _profiler_exception_css    ANY      ANY      ANY    /_profiler/{token}/exception.css
 -------------------------- -------- -------- ------ -----------------------

我手动创建了目录/ _wdt,以防万一,但它没有改变任何东西.

我用debug调试了错误:event-dispatcher,没什么特别的.

我注意到探查器的缓存位于该目录中:var/cache/dev/profiler/03/74 /并命名为177403

还有一件事,我用'root'用户运行了作曲家.我用chown来改变我的项目的所有者.

这是我文件的一部分.env:

###> symfony/framework-bundle ###
APP_ENV=dev

Answer 1

我认为这需要htaccess或mod_rewrite

composer require symfony/apache-pack

• 配置Web服务器

  https://symfony.com/doc/current/setup/web_server_configuration.html

Answer 2

composer require symfony/apache-pack

Do you want to execute this recipe?
    [y] Yes
    [n] No
    [a] Yes for all packages, only for the current installation session
    [p] Yes permanently, never ask again for this project
    (defaults to n): y

主机文件：

127.0.0.1 symfony01.com
127.0.0.1 www.symfony01.com

httpd-vhosts.conf ：

<VirtualHost *:80>
    ServerName symfony01.com
    ServerAlias www.symfony01.com   
    DocumentRoot "c:/wamp64/www/symfony01/public"
    <Directory  "c:/wamp64/www/symfony01/public/">
        Options +Indexes +Includes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Answer 3

如果您使用的是 symfony v5. *
去your_project_root > public创建一个名为的新文件.htaccess 只需粘贴代码：

DirectoryIndex index.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]
    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 307 ^/$ /index.php/
    </IfModule>
</IfModule>

由于回复是在评论中,我重复一遍:

您是否尝试过URL http://www.elora.dev/index.php/_wdt/？我有一个类似的问题,因为URL重写是错误的.- AL

而已 !

1. /index.php对调试工具栏没有任何问题
2. /index.php/lucky/number有效

非常感谢AL

Answer 5

只需添加：

FallbackResource /index.php

在您的目录设置中

    <Directory "/Library/WebServer/Documents/Your_public_symfony_directory">
            ....
            FallbackResource /index.php
            ....
    </Directory>

Answer 6

Il 听起来像是缓存写入问题。由于调试数据写入缓存文件夹，探查器/调试工具栏崩溃。您的应用程序可能在prod环境中运行良好。

要查看这是否是您的问题，请尝试运行chmod -R 777 var/cache，然后重试。

“更好的修复”取决于您的操作系统。请随意添加更多信息以准确回答，否则您可以在此处查看 Symfony 相关文档（故意过时的链接，他们从 SF4 文档中删除了它）。
