Inject current route in custom class (Symfony 2.8)

inject_current_route_class.md

Use request_stack, for instance:

services:
    app.service:
        class: AppBundle\Class
        arguments: ["@request_stack"]

And in the class:

function __construct(\Symfony\Component\HttpFoundation\RequestStack $requestStack) {
		$request = $requestStack->getCurrentRequest();		
		$route = $request->attributes->get('_route');
	}
