How to Force Routes to Always Use HTTPS or HTTP
Warning: You are browsing the documentation for Symfony 3.x, which is no longer maintained.
Read the updated version of this page for Symfony 7.2 (the current stable version).
Sometimes, you want to secure some routes and be sure that they are always
accessed via the HTTPS protocol. The Routing component allows you to enforce
the URI scheme with the schemes
setting:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
// src/AppBundle/Controller/MainController.php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Routing\Annotation\Route;
class MainController extends Controller
{
/**
* @Route("/secure", name="secure", schemes={"https"})
*/
public function secureAction()
{
// ...
}
}
The above configuration forces the secure
route to always use HTTPS.
When generating the secure
URL, and if the current scheme is HTTP, Symfony
will automatically generate an absolute URL with HTTPS as the scheme, even when
using the path()
function:
1 2 3 4 5 6 7
{# If the current scheme is HTTPS #}
{{ path('secure') }}
{# generates a relative URL: /secure #}
{# If the current scheme is HTTP #}
{{ path('secure') }}
{# generates an absolute URL: https://example.com/secure #}
The requirement is also enforced for incoming requests. If you try to access
the /secure
path with HTTP, you will automatically be redirected to the
same URL, but with the HTTPS scheme.
The above example uses https
for the scheme, but you can also force a URL
to always use http
.
Note
The Security component provides another way to enforce HTTP or HTTPS via
the requires_channel
setting. This alternative method is better suited
to secure an "area" of your website (all URLs under /admin
) or when
you want to secure URLs defined in a third party bundle (see
How to Force HTTPS or HTTP for different URLs for more details).
