-Like you can easily imagine, the :class:`Symfony\\Component\\Httpfoundation\\RequestStack` is the best option to gain access to the request, using this approach, a simple update is recommended and the access to request parameters is way easier::
-
- <?php
-
- namespace AppBundle\Action;
-
- use Twig\Environment;
- use Symfony\Component\HttpFoundation\Response;
- use Symfony\Component\HttpFoundation\RequestStack;
-
- final class HelloAction
- {
- private $requestStack;
-
- private $twig;
-
- public function __construct(RequestStack $requestStack, Environment $twig)
- {
- $this->requestStack = $requestStack
- $this->twig = $twig;
- }
-
- public function __invoke(): Response
- {
- $data = $this->requestStack->getCurrentRequest()->get('id');
-
