How to Retrieve the Request from the Service Container

Whenever you need to access the current request in a service, you can either add it as an argument to the methods that need the request or inject the request_stack service and access the Request by calling the :method:`Symfony\\Component\\HttpFoundation\\RequestStack::getCurrentRequest` method:

namespace AppBundle\Newsletter;

use Symfony\Component\HttpFoundation\RequestStack;

class NewsletterManager
{
    protected $requestStack;

    public function __construct(RequestStack $requestStack)
    {
        $this->requestStack = $requestStack;
    }

    public function anyMethod()
    {
        $request = $this->requestStack->getCurrentRequest();
        // ... do something with the request
    }

    // ...
}

Now, just inject the request_stack, which behaves like any normal service. If you're using the :ref:`default services.yml configuration <service-container-services-load-example>`, this will happen automatically via autowiring.

Tip

In a controller you can get the Request object by having it passed in as an argument to your action method. See :ref:`controller-request-argument` for details.
