Symfony 4, How to implement a general controller as a service?

Question

I have this controller

Controller1.php

Answer 1

It looks like your import of the service is wrong and some other things that we spoke about in tchat.

Important :

• The service should be in src/Servicefolder.
• The service should not be excluded in services.yml

Final solution for people :

The service :

namespace App\Service;

use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Doctrine\ORM\EntityManagerInterface; 

class GeneralService
{

    private $entityManager;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->entityManager = $entityManager;
    } 

    /**
     * @param Request $request
     * @param String $entity
     * @return JsonResponse
     */
    public function list(Request $request, String $entity)
    {
        if (empty($request->headers->get('api-key'))) {
            return new JsonResponse(['error' => 'Please provide an API_key'], 401);
        }

        if ($request->headers->get('api-key') !== $_ENV['API_KEY']) {
            return new JsonResponse(['error' => 'Invalid API key'], 401);
        }

        return new JsonResponse($this->entityManager->getRepository($entity)->findAll()); 
    }

}

And the controller :

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use App\Service\GeneralService;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;

class SubscriptionController extends AbstractController
{

    /**
    * @Route("/Some/Uri", methods={"GET"})
    * @param GeneralService $generalService
    * @param Request $request
    * @return JsonResponse
    */
    public function AuthenticateAPI(GeneralService $generalService, Request $request)
    {
        $AuthenticatorObject = $generalService->list($request , 'App\Entity\Something');
        return $AuthenticatorObject;
    }
}
