我已将sonata admin添加到我的网站。
在本地，我可以访问路径/admin，但是当我将其推送到产品环境时却无法访问。尝试访问它时，我得到 404 ：
未找到 在此服务器上找不到请求的URL / admin。
我已删除var/cache/prod中的缓存
万一这是我使用的sonata_admin.yaml的内容，
_sonata_admin:
resource: .
type: sonata_admin
prefix: /admin
admin_area:
resource: "@SonataAdminBundle/Resources/config/routing/sonata_admin.xml"
prefix: /admin
sonata_user_admin_security:
resource: '@SonataUserBundle/Resources/config/routing/admin_security.xml'
prefix: /admin
sonata_user_admin_resetting:
resource: '@SonataUserBundle/Resources/config/routing/admin_resetting.xml'
prefix: /admin/resetting
我是否必须配置一些内容才能访问服务器上的这些路径？还是与.htaccess文件有关。
任何可能导致此问题的线索？
预先感谢您的帮助！
更新：这是在本地主机上执行debug:router命令（在生产环境中无法执行）时得到的内容

答案 0 :(得分：1)
找到了解决方案：
在 Symfony 4.x 中，我们需要指定特定的重写规则。
我遵循了Symfony 4 documentation。 我只需要执行以下命令即可解决此问题：
composer require symfony/apache-pack
您也可以将此代码添加到Symfony项目的.htaccess子目录的public文件中：
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
RedirectMatch 302 ^/$ /index.php/
</IfModule>
</IfModule>
瞧瞧！ /admin和所有子路径现在都可以在服务器上访问了。
