我的解决方案 - 通过装饰 FOS 控制器服务在 Symfony 4.1 中工作正常.
首先 - 装饰选定的控制器(文档:https://symfony.com/doc/current/service_container/service_decoration.html)内

My solution - works fine from Symfony 4.1 by decorate FOS controller service.
Firstly - decorate selected controller (docs: https://symfony.com/doc/current/service_container/service_decoration.html) inside

App\Controller\ResettingController:
   decorates: fos_user.resetting.controller
   arguments:
   - '@App\Controller\ResettingController.inner'
   - '@event_dispatcher'
   - '@fos_user.resetting.form.factory'
   - '@fos_user.user_manager'
   - '@fos_user.util.token_generator'
   - '@fos_user.mailer'
   - '%fos_user.resetting.retry_ttl%'
   - '@security.csrf.token_manager'

现在将覆盖原始重置控制器的控制器:

Now controller which will override original ResettingController:

<?php

namespace App\Controller;

use FOS\UserBundle\Controller\ResettingController as BaseResettingController;
use FOS\UserBundle\Form\Factory\FactoryInterface;
use FOS\UserBundle\Mailer\MailerInterface;
use FOS\UserBundle\Model\UserManagerInterface;
use FOS\UserBundle\Util\TokenGeneratorInterface;
use Symfony\Component\EventDispatcher\EventDispatcherInterface;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Csrf\CsrfTokenManagerInterface;

    public function __construct(

        $this->csrfTokenManager = $csrfTokenManager;
    }

    public function requestAction()
    {
        return $this->resettingController->requestAction();
    }

    /**

     */
    public function sendEmailAction(Request $request)
    {

    }

    }

    /**

     */
    public function resetAction(Request $request, string $token)
    {
        // custom reset action
    }
}
