Symfony2: Getting Route in Page Load Event Listener

Question

How can I get the route in a page load even listener?

I have the following code in services.yml:

    page_load_listener:
    class: Acme\\MainBundle\

All kernel events extend KernelEvent, which means you can simply acess the Request object via $event->getRequest().

public function onKernelController(FilterControllerEvent $event)
{
    $request = $event->getRequest();

    // Matched route
    $_route  = $request->attributes->get('_route');

    // Matched controller
    $_controller = $request->attributes->get('_controller');

    // All route parameters including the `_controller`
    $params      = $request->attributes->get('_route_params');
}

If you'd like to get plain route attributes, simply filter out all the elements prefixed with "_".

Choosing the proper event to listen to depends on your specific use case.
