Routing won't work when there is a slash behind - php

Question

My route cannot be found if I add a / at the end as you see below.
class QuizController extends Controller {
/**
* #Route("/quiz/{name}")
*/
public function showAction($name = '') {
$templating = $this->container->get('templating');
$html = $templating->render('quiz/show.html.twig', [
'name' => $name,
'title' => 'Hello World'
]);
return new Response($html);
}
}
The problem is:
myurl/quiz/whatever works
myurl/quiz works
myurl/quiz/ doesn't work
Whenever there is a slash but no value behind, I get the message
No route found for "GET /"
I'm new to Symfony. How can I fix this?

Answer 1

Using myurl/quiz indicates the {name} parameter is not used, but when you use myurl/quiz/ it needs the {name} parameter to be passed in.
Suggests you add defaults and a name for the route like so:
/**
* #Route("/quiz/{name}")
* defaults={"name" = 0},
* name="quiz")
*/
Then if you use myurl/quiz/ it will send myurl/quiz/0. This is an example

Answer 2

Add the ending slash in the route declaration, the route without / will be automatically redirected to the one with the /
class QuizController extends Controller
{
/**
* #Route("/quiz/{name}/")
*/
public function showAction($name = '')
{
$templating = $this->container->get('templating');
$html = $templating->render('quiz/show.html.twig', [
'name' => $name,
'title' => 'Hello World'
]);
return new Response($html);
}
}

Answer 3

Edit (via phone) After OP comments Below:
put 2 #Route declarations before controller action, one with slash one without
#Route("/quiz/")
#Route("/quiz/{name}")
Since OP wants the same route controller to handle both trailing slash and non-trailing slash, the solution is the allow Symfony to accept a slash as part of the variable (which is doesn't by default).
Docs Here : http://symfony.com/doc/current/routing/slash_in_parameter.html
So your route becomes
class QuizController extends Controller {
/**
* #Route("/quiz{name}", name="quiz_name", requirements={"name"=".+"})
*/
public function showAction($name = '') {
$templating = $this->container->get('templating');
$html = $templating->render('quiz/show.html.twig', [
'name' => $name,
'title' => 'Hello World'
]);
return new Response($html);
}
}
Please Note: While this answers the OP's question, it's a dangerour practice. For anyone reading this, it might suit the OP for his logic but note that it will also match any route
/quiz*
So while the OP wants this, it will also match
/quiz/name
/quiz/
/quiz
/quiz/name/edit
/quiz/name/delete
For OP, a work-around is to include edit, delete routes before this custom one as Symfony matches routes by first match wins basis.
