Symfony 2：尝试打开/app_dev.php时出现404未找到错误

symfonynginxhttp-status-code-404symfony-2.1profiler

14

我尝试打开 /app_dev.php 时收到了这个错误消息。

An error occurred while loading the web debug toolbar (404: Not Found).

Do you want to open the profiler?

当我点击确定时，我会得到以下错误：

app_dev.php/_profiler/5053258a822e1

并且

404 Not found

我正在使用nginx

非常感谢您的帮助。

编辑：这里是错误日志：

[error] 18369#0: *9 open() "/var/www/Symfony/web/app_dev.php/_wdt/5056f875afc98" failed (20: Not a directory), client: 127.0.0.1, server: symfony, request: "GET /app_dev.php/_wdt/5056f875afc98 HTTP/1.1", host: "symfony", referrer: "http://symfony/app_dev.php"

编辑2：

当我尝试访问app_dev.php时，页面会打开，但没有工具栏。当我尝试使用app_dev.php/时，我得到了

**Oops! An Error Occurred
The server returned a "404 Not Found".
Something is broken. Please e-mail us at [email] and let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused. **

错误。

你能发布一下你的nginx错误日志吗？（不仅仅是浏览器中打印出来的内容！） - Florent

我曾经遇到过同样的错误，但后来发现只有在输入 app_dev.php/ 而不是请求 app_dev.php 时才会输出该消息（注意斜杠 /）。

我认为这与路由器有关，但这只是一个猜想。

我的错误与Nginx配置有关（使用Symfony 3.1），我只是编辑了Symfony推荐的Nginx配置。

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

也许是由于符号链接的原因，我不确定。

我将一小部分内容复制到Nginx默认配置中，并进行编辑以匹配所有.php文件。

##

# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

        # When you are using symlinks to link the document root to the

        # Otherwise, PHP's OPcache may not properly detect changes to

我建议遵循Symfony的生产服务器规范。

在Symfony2中以开发者模式显示Web调试工具栏，页面应该具有有效的HTML。

谢谢@Rafal，但我正在尝试打开app_dev.php文件，这是来自Symfony网站的。如何解决这个问题？ - Milos Cuculovic

这发生在我的开发环境中，所以我在我的虚拟主机配置文件中注释了指令DirectoryIndex，现在我可以通过以下方式访问我的应用程序：http://127.0.0.1/app_dev.php，并且不再出现有关分析器的错误！我使用的是Symfony 2.3.x。

我已经找到了解决方案（或多或少）。我拿了另一个现有的Symfony项目，现在一切都正常工作。我真的不知道为什么Symfony标准版本在我的情况下无法工作...如果有人需要空的Symfony项目，我可以上传存档。

请注意您的 .htaccess 文件，我也遇到了这个问题并解决了。

    <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>

我知道这不完全是你所要求的，但它可能会帮助未来搜索此问题的人，就像 @yvoyer建议的那样，我的问题也是因为尾随斜杠，我的服务器使用了nginx和fpm，在nginx中，//并不等于/，所以我需要在虚拟主机配置上做一些修复，然后它就可以正常工作了。我将把配置粘贴给需要的人，或者建议更好的一个。

    location / {
            try_files $uri @pass_to_symfony;
    }

    location ~ /app_dev.php/ {
            try_files $uri @pass_to_symfony_dev;
    }

    location @pass_to_symfony{
            rewrite ^ /app.php?$request_uri last;
    }

    location @pass_to_symfony_dev{
            rewrite ^ /app_dev.php?$request_uri last;
    }

    location ~ ^/app(_dev)?\.php($|/) {
            include fastcgi_params;
            fastcgi_pass   unix:/var/run/php5-fpm.sock; # replace with your sock path
    }
