php - Heroku 上的 Symfony : 403 Forbidden You don't have permission to access/on this server

Question

我已成功将我的 Symfony 2 应用程序部署到 Heroku，但现在，当我尝试访问它时，我收到以下 403 错误:

Forbidden

You don't have permission to access / on this server.

这是来自 Heroku 的日志:

似乎 Symfony(或 Heroku？)正在尝试为目录 /app/ 提供服务，但我认为这是不正确的，从日志中可以看出:

2015-07-29T14:31:41.828428+00:00 app[web.1]: [Wed Jul 29 14:31:41.827438 2015] [autoindex:error] [pid 104:tid 140466989270784] [client 10.100.0.139:16096] AH01276: Cannot serve directory /app/: No matching DirectoryIndex (index.php,index.html,index.htm) found, and server-generated directory index forbidden by Options directive

在 tutorial on the Symfony Documentation about how to deploy to Heroku 之后，我已经创建了我的 .procfile 并放入了:

web: bin/heroku-php-apache2 web/

我还删除了 DemoBundle，现在我的根 URL 以这种方式在 DefaultController 中配置:

<?php

// \AppBundle\Controller\DefaultController.php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DefaultController extends Controller
{
    /**
     * @Route("/", name="Homepage")
     */
    public function indexAction()
    {
        return $this->render('default/index.html.twig');
    }
}

我认为，最终，我的 .htaccess 存在一些问题，即 Symfony 标准版附带的那个:

# Use the front controller as index file. It serves as a fallback solution when
# every other rewrite/redirect fails (e.g. in an aliased environment without
# mod_rewrite). Additionally, this reduces the matching process for the
# start page (path "/") because otherwise Apache will apply the rewriting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex app.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    # Determine the RewriteBase automatically and set it as environment variable.
    # If you are using Apache aliases to do mass virtual hosting or installed the
    # project in a subdirectory, the base path will be prepended to allow proper
    # resolution of the app.php file and to redirect to the correct URI. It will
    # work in environments without path prefix as well, providing a safe, one-size
    # fits all solution. But as you do not need it in this case, you can comment
    # the following 2 lines to eliminate the overhead.
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    # Sets the HTTP_AUTHORIZATION header removed by apache
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Redirect to URI without front controller to prevent duplicate content
    # (with and without `/app.php`). Only do this redirect on the initial
    # rewrite by Apache and not on subsequent cycles. Otherwise we would get an
    # endless redirect loop (request -> rewrite to front controller ->
    # redirect -> request -> ...).
    # So in case you get a "too many redirects" error or you always get redirected
    # to the start page because your Apache does not expose the REDIRECT_STATUS
    # environment variable, you have 2 choices:
    # - disable this feature by commenting the following 2 lines or
    # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
    #   following RewriteCond (best solution)
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

    # If the requested filename exists, simply serve it.
    # We only want to let Apache serve files and not directories.
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    # Rewrite all other queries to the front controller.
    RewriteRule .? %{ENV:BASE}/app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the start page 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>

我的应用程序的另一部分可能是导致此问题的原因:security.yml，目前是这样的:

# you can read more about security in the related section of the documentation
# http://symfony.com/doc/current/book/security.html
security:
# http://symfony.com/doc/current/book/security.html#encoding-the-user-s-password

        anonymous: true

    # disables authentication for assets and the profiler, adapt it according to your needs
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false

# with these settings you can restrict or allow access for different parts
# of your application based on roles, ip, host or methods
# http://symfony.com/doc/current/cookbook/security/access_control.html
access_control:
    #- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }
    - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }

但是，访问 http://my-app.herokuapp.com/login(这似乎是“向世界开放”)，无论如何我都会收到一个漂亮的 404 错误:

Not Found

The requested URL /login was not found on this server.

那么，这可能是问题所在？哪个设置阻止我在 Heroku 上访问我的 Symfony 应用程序？

Answer 1

这是不可能的。 3个多小时才找到解决办法。我在此处发布的所有代码中都找不到解决方案。

一个真正、简单、愚蠢、小型的解决方案:procfile 名称。你注意到了吗？我都是用小写字母写的。

解决方案？ Procfile，首字母大写。

这真是太糟糕了，但我终于启动并运行了我的应用程序! :D
