Catch-all route in Symfony 3

Question

I have a catch-all fallback route in Symfony2 that I couldn't get to work in Symfony3. I tried this exact syntax (a verbatim copy of my Symfony2 route) and that didn't work.

fallback:
    path:     /{req}
    defaults: { _controller: MyBundle:Default:catchAll }
    requirements:
        req: ".+"

How can I get this working in Symfony3? (It's literally the only thing holding me back from using Symfony3 and keeping me at v2.8)

Answer 1

This should help you:

route1:
  path: /{req}
  defaults: { _controller: 'AppBundle:Default:index' }
  requirements:
      req: ".+"

Where, my controller is called "DefaultController", and I have a function called "indexAction()".

Here is my code for the DefaultController:

class DefaultController extends Controller
{
    /**
     * @Route("/", name="homepage")
     */
    public function indexAction(Request $request)
...

I actually did try what you said in my environment, and it didn't work until I had the right controller settings specified.

EDIT:

For this to work, it was necessary to add the parameter Request $request (with the type hint) to the action's method signature.
