Symfony：如何将参数从Route传递到Controller而没有路径

Question

I have a route

   detail:
      path:     /{code}
      defaults: { _controller: controller.main:detailAction }

I also have a controller for this route

 public function detailAction(Request $request, string $code, int $size, array $params): Response
 {
 }

My question is: how can I say to controller which parameters he should take as int $size and array $params ? I have found in symfony docs that I may specifically mention params in defaults section with default values like this

   detail:
      path:     /{code}
      defaults: { _controller: controller.main:detailAction }
      size:        1
      params:      "Hello world!"

But that is not what I want since I shouldn't have a default value for this params but it ought to be taken directly from request. How do I do this without making my route like /{code}/{size} ? And even in this case what do I do with an array?

Answer 1

You can generate a url like this by passing parameters in your controller:

 $url = $this->generateUrl("detail", array("code" => $code, ...));

    return $this->redirect($url);

And routing:

  detail:
     path:     /
     defaults: { _controller: controller.main:detailAction }

If you want to specify parameters like this

someurl.io/action/?filter=allopenissues&orderby=created

You should typehint Request object in your action and access its query parameters bag. If your controller extends Symfony Controllers, Request will be automatically passed.

use Symfony\Component\HttpFoundation\Request;
....
public function updateAction(Request $request)
{
    $request->query->get('myParam'); // get myParam from query string 
}
