inanzzz | Forwarding a request from one controller method to another controller method

This example uses Dependency Injection and the target controller has constructor parameters in it.

controllers.yml

services:
    application_api.controller.abstract:
        class: Application\ApiBundle\Controller\AbstractController
        abstract: true
        arguments:
            - @serializer

    application_api.controller.receiver:
        class: Application\ApiBundle\Controller\ReceiverController
        parent: application_api.controller.abstract
        arguments:
            - @application_api.service.api

    application_api.controller.sender:
        class: Application\ApiBundle\Controller\SenderController
        parent: application_api.controller.abstract
        arguments:
            - @http_kernel

ReceiverController

This controller also makes a call to another service by passing all the URI query parameters, request body content, http method and original request uri so you better print them out to see what exactly is being received.

/**
 * @Route("/receiver", service="application_api.controller.receiver")
 */
class ReceiverController extends AbstractController
{
    private $apiService;

    public function __construct(
        SerializerInterface $serializer,
        ApiServiceInterface $apiService
    ) {
        parent::__construct($serializer);

        $this->apiService = $apiService;
    }

    /**
     * @param Request $request
     *
     * @Secure(roles="ROLE_ADMIN")
     *
     * @Route("/give-it-to-me/{id}", requirements={"id"="([0-9]){8}"})
     *
     * @return Response
     */
    public function givItToMeAction(Request $request)
    {
        $result = $this->apiService->call(
            $request->getPathInfo(),
            $request->getMethod(),
            $request->query->all(),
            $request->getContent()
        );

        return new Response($result);
    }
}

SenderController

If the controller wasn't declared as a service, we could just use '_controller' => 'ApplicationApiBundle:Receiver:givItToMe' below.

/**
 * @Route("/sender", service="application_api.controller.sender")
 */
class ReceiverController extends AbstractController
{
    private $httpKernel;

    public function __construct(
        SerializerInterface $serializer,
        HttpKernelInterface $httpKernel
    ) {
        parent::__construct($serializer);

        $this->httpKernel = $httpKernel;
    }

    /**
     * @param Request $request
     *
     * @Method({"PATCH"})
     * @Secure(roles="ROLE_ADMIN")
     * @Route("/take-it/{id}", requirements={"id"="([0-9]){8}"})
     *
     * @return Response
     */
    public function takeItAction(Request $request)
    {
        $attributes = [
                '_controller' => 'application_api.controller.receiver:givItToMeAction',
                'request' => $request
        ];
        $subRequest = $request->duplicate([], null, $attributes);

        /** @var Response $response */
        $response = $this->httpKernel->handle($subRequest, HttpKernelInterface::SUB_REQUEST);

        return $response;
    }
}

Example request

PATCH /api/sender/take-it/123
{
   "key": "value"
}
