Symfony：htaccess 隐藏 app.php 或 app_dev.php

Question

我知道这个问题已经被问过很多次了，但是有些奇怪的事情发生在我身上。 Apache DocumentRoot 指向 symfony/web/，这是我在 web/ 目录中的 .htaccess：

DirectoryIndex app_dev.php
#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_FILENAME} -f
    RewriteRule ^(.*)$ app_dev.php [QSA,L]
    #RewriteRule ^(.*)$ app.php [QSA,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>

嗯，事情是 www.example.com/route1/ 正在工作，而 www.example.com/route2/ 正在抛出错误：

哎呀！发生错误 服务器返回“404 Not Found”。 东西坏了。请通过 [email] 给我们发送电子邮件，并让我们知道发生此错误时您在做什么。我们会尽快修复它。给您造成的任何不便，请原谅。

虽然www.example.com/app_dev.php/route2/ 工作正常（还有www.example.com/app_dev.php/route1/）

帮助？

更新。 prod 中的缓存清除会引发此错误（我以前从未尝试过，我正在开发）：

[Doctrine\Common\Proxy\Exception\UnexpectedValueException] “MyProject\PanelBundle\Entity\User”类的“addRole”方法中参数“userRoles”的类型提示无效。

[反射异常] 类 Maycol\BlogBu​​ndle\Entity\Role 不存在

这是对我有用的 .htaccess：

DirectoryIndex app.php
#DirectoryIndex app_dev.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    # 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 startpage 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_dev\.php(/(.*)|$) %{CONTEXT_PREFIX}/$2 [R=301,L]
    RewriteRule ^app\.php(/(.*)|$) %{CONTEXT_PREFIX}/$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]


    RewriteCond %{REQUEST_FILENAME} -f
    #RewriteRule ^(.*)$ app_dev.php [QSA,L]
    RewriteRule ^(.*)$ app.php [QSA,L]

    # The following rewrites all other queries to the front controller. The
    # condition ensures that if you are using Apache aliases to do mass virtual
    # hosting, the base path will be prepended to allow proper resolution of the
    # app.php file; it will work in non-aliased environments as well, providing
    # a safe, one-size fits all solution.
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)(.+)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    #RewriteRule .? %{ENV:BASE}app_dev.php [L]
    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 startpage to the front controller explicitly so that the website
        # and the generated links can still be used.
        #RedirectMatch 302 ^/$ /app_dev.php/
        RedirectMatch 302 ^/$ /app.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>

此错误与 Apache/htaccess 无关。这个 404 错误页面是 symfony 本身的默认页面！

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.

没有匹配 /route2 的路由。像这样检查您的路由：

php app/console router:debug 

为了更快地检查它，使用 grep 或 findstr (Windows)

php app/console router:debug | grep route2

还请检查您的路由是否仅在 dev 环境中配置（即仅在 routing_dev.yml 中）！

php app/console router:debug --env=prod

请使用 ... 清除您的生产缓存

php app/console cache:clear --env=prod

...如果有未捕获的异常导致访问页面时显示的 404 页面，请检查您的日志文件。例如，您可以使用此命令查看生产日志文件中的实时更改。

tail -f app/logs/prod.log
