Redirect URLs with a Trailing Slash
The goal of this cookbook is to demonstrate how to redirect URLs with a
trailing slash to the same URL without a trailing slash
(for example /en/blog/ to /en/blog).
Create a controller that will match any URL with a trailing slash, remove the trailing slash (keeping query parameters if any) and redirect to the new URL with a 301 response status code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
// src/Acme/DemoBundle/Controller/RedirectingController.php
namespace Acme\DemoBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class RedirectingController extends Controller
{
public function removeTrailingSlashAction(Request $request)
{
$pathInfo = $request->getPathInfo();
$requestUri = $request->getRequestUri();
$url = str_replace($pathInfo, rtrim($pathInfo, ' /'), $requestUri);
return $this->redirect($url, 301);
}
}After that, create a route to this controller that's matched whenever a URL with a trailing slash is requested. Be sure to put this route last in your system, as explained below:
- YAML
- XML
- PHP
1 2 3 4 5 6
remove_trailing_slash:
path: /{url}
defaults: { _controller: AcmeDemoBundle:Redirecting:removeTrailingSlash }
requirements:
url: .*/$
_method: GETNote
Redirecting a POST request does not work well in old browsers. A 302 on a POST request would send a GET request after the redirection for legacy reasons. For that reason, the route here only matches GET requests.
Caution
Make sure to include this route in your routing configuration at the very end of your route listing. Otherwise, you risk redirecting real routes (including Symfony2 core routes) that actually do have a trailing slash in their path.
