Symfony2 Routing - route subdomains

Question

Is there a way to set up hostname based routing in Symfony2?

I didn't find anything about this topic in the official documentation.
http://symfony.com/doc/2.0/book/routing.html

I want to route the request based on the given hostname:
foo.example.com
bar.example.com
{{subdomain}}.example.com

So in essence, the controller would get the current subdomain passed as a parameter.

Similar to the Zend solution:
http://framework.zend.com/manual/en/zend.controller.router.html#zend.controller.router.routes.hostname

$hostnameRoute = new Zend_Controller_Router_Route_Hostname(
    ':username.users.example.com',
    array(
        'controller' => 'profile',
        'action'     => 'userinfo'
    )
);
$plainPathRoute = new Zend_Controller_Router_Route_Static('');

$router->addRoute('user', $hostnameRoute->chain($plainPathRoute));

I hope that it's possible and I just missed it somehow.
Thanks in advance!

Solution 1

This is my solution:

In the config.yml inside app dir add the following lines:

services:
   kernel.listener.subdomain_listener:
       class: Acme\DemoBundle\Listener\SubdomainListener
       tags:
           - { name: kernel.event_listener, event: kernel.request, method: onDomainParse }

Then create the class SubdomainListener.php as:

<?php

namespace Acme\DemoBundle\Listener;

use Symfony\Component\EventDispatcher\EventDispatcher;
use Symfony\Component\EventDispatcher\Event;

class SubdomainListener
{
   public function onDomainParse(Event $event)
   {
       $request = $event->getRequest();
       $session = $request->getSession();

       // todo: parsing subdomain to detect country

       $session->set('subdomain', $request->getHost());
   }
}

Solution 2

Just to point out that this is now added in Symfony v2.2 - http://symfony.com/doc/master/components/routing/hostname_pattern.html.

mobile_homepage:
    path:     /
    host:     m.{domain}
    defaults: { _controller: AcmeDemoBundle:Main:mobileHomepage }
    requirements:
        domain: %domain%

homepage:
    path:  /
    defaults: { _controller: AcmeDemoBundle:Main:homepage }

Solution 3

I assume that subdomain routing in symfony2 is process of choose defined controller in according to subdomain part of hostname, and session variable is not help to resolve defined controller.

I set request attribute: _controller, in kernel listener like this

$request->attributes->set('_controller','AcmeBundle:Demo:main');

This is help to route to defined controller, but I lose debug profiler in dev environment, still I can not detect a cause

Solution 4

Alternatively get hostname in the controller:

class DefaultController extends PowmaController {

  /**
   * @Route("/test")
   */
  public function testAction() {
    return new Response( 'Hostname ' . $this->getRequestHostnameString() );
  }

  function getRequestHostnameString() {
    return $this->getRequest()->getHost();
  }

Solution 5

There is a plugin for Symfony 1.2 that adds this functionality. The code is only a few hundred lines in a single file and shouldn't be too diffcult to port to Symfony 2. But the documentation from Sensio isn't quite there yet.

You could also not include the subdomain in the route and fetch the domain from the controller and process it there. I think it's this method: getHost()
