Get the current route and url in a Symfony 2 controller

Problem:

How do I get the current page's URL and current route in a Symfony 2 controller?

Solution:

There are several ways to get the current page's route and url. One way is demonstrated here.

Current route

public function someAction(Request $request){
  // ... some code here

  $currentRoute = $request->attributes->get('_route');

  // more code ...
}

Current URL

public function someAction(Request $request){
  // ... some code here
  
  $currentRoute = $request->attributes->get('_route');
  $currentUrl = $this->get('router')
                     ->generate($currentRoute, array(), true);
  
  // more code ...
}

Updated:

Alternatively, you can also generate the current URL directly without using the current route (thanks COil for the comment!)

$currentUrl = $this->getRequest()->getUri();

$currentUrl = $request->getUri();
//(see comments below, thanks Marcos for the comment!)

Notes:

This was tested to work using Symfony2 version 2.0.4.
