Symfony4 resource controller - api

Question

I am developing an API under symfony4 and I wish I could create a parent controller that I could use to call functions that would be repeated in another controller. Here are my controllers that I would like to extend from a parent controller:
My DeliveryController:
<?php
namespace App\Controller;
use App\Entity\DeliveryMan;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
use Symfony\Component\Routing\Annotation\Route;
/**
* Class AuthController
* #package App\Controller
* #Route("/api")
*/
class DeliveryController extends AbstractController
{
/**
* #Route(
* name="api_delivery_man_post",
* path="/delivery_man",
* methods={"POST"},
* defaults={
* "_api_resource_class"=DeliveryMan::class,
* "_api_collection_operation_name"="post"
* }
* )
*/
public function postAction(DeliveryMan $data, UserPasswordEncoderInterface $encoder): DeliveryMan
{
return $this->encodePassword($data, $encoder);
}
protected function encodePassword(DeliveryMan $data, UserPasswordEncoderInterface $encoder): DeliveryMan
{
$encoded = $encoder->encodePassword($data, $data->getPassword());
$data->setPassword($encoded);
return $data;
}
}
My AuthController:
<?php
namespace App\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use App\Entity\User;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
/**
* Class AuthController
* #package App\Controller
* #Route("/api")
*/
class AuthController extends AbstractController
{
/**
* #Route(
* name="api_users_post",
* path="/users",
* methods={"POST"},
* defaults={
* "_api_resource_class"=User::class,
* "_api_collection_operation_name"="post"
* }
* )
*/
public function postAction(User $data, UserPasswordEncoderInterface $encoder): User
{
return $this->encodePassword($data, $encoder);
}
protected function encodePassword(User $data, UserPasswordEncoderInterface $encoder): User
{
$encoded = $encoder->encodePassword($data, $data->getPassword());
$data->setPassword($encoded);
return $data;
}
}
As can be seen I call 2 identical actions in 2 different controllers the only difference that there would be the entities and the path of the road.
So I was thinking of creating a ResourceController parent controller that would be extended from AbstractController and that the child controllers would be extended from ResourceController but I do not see how after how to create my methods in my parent controller and retrieve them in the child controllers.
If someone has already done that I am a taker :) Thank you for your help.
EDIT Result ResourceController:
<?php
namespace App\Controller;
use App\Entity\DeliveryMan;
use App\Entity\User;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
class ResourcesController extends AbstractController
{
private $encoder;
public function __construct(UserPasswordEncoderInterface $encoder)
{
$this->encoder = $encoder;
}
public function encodePassword(User $data): User
{
$encoded = $this->encoder->encodePassword($data, $data->getPassword());
$data->setPassword($encoded);
return $data;
}
public function encodePasswordDelivery(DeliveryMan $data): DeliveryMan
{
$encoded = $this->encoder->encodePassword($data, $data->getPassword());
$data->setPassword($encoded);
return $data;
}
}

Just make a ResourceController wich extends Symfony AbstractController.
Write your 2 shared methods here, then in any Controller that extends ResourceController you can call them as you would normally call a class method: using $this
class ResourceController extends AbstractController
{
private $encoder;
public function __construct(UserPasswordEncoderInterface $encoder)
{
$this->encoder = $encoder;
}
public function encodePassword(Object $data): Object
{
$encoded = $this->encoder->encodePassword($data, $data->getPassword());
$data->setPassword($encoded);
return $data;
}
}
class AuthController extends ResourceController
{
public function someAction(User $data)
{
return $this->encodePassword($data);
}
}
I also suggest you write an interface with a getPassword method that User and DeliveryMan will implements. Not only you'll ensure that the method is implemented but you' also be able to typehint, say AuthenticatedEntityInterface, instead of Object
