如何在symfony中調用redirectToRoute方法接受控制器

Question

我是symfony的新手，在任何用戶登錄系統后我都會執行一些過程，以便提供一項服務，代碼如下：

security.authentication.success_handler:
        class:   AppBundle\Handler\AuthenticationSuccessHandler
        arguments:  ["@security.http_utils", {}]
        tags:
            - { name: 'monolog.logger', channel: 'security' }

在安全性文件中添加以下代碼行：

success_handler: security.authentication.success_handler

在文件夾處理程序的下面的代碼中新建一個AuthenticationSuccessHandler文件：

<?php

namespace AppBundle\Handler;

use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Http\Authentication\DefaultAuthenticationSuccessHandler;
use Symfony\Component\Security\Http\HttpUtils;
use Symfony\Component\HttpFoundation\Response;


class AuthenticationSuccessHandler extends DefaultAuthenticationSuccessHandler {

    public function __construct(HttpUtils $httpUtils, array $options ) {

        parent::__construct( $httpUtils,$options);
    }

    public function onAuthenticationSuccess( Request $request, TokenInterface $token ) {
        $user=$token->getUser();
        if (!empty($user) && $user->hasRole('ROLE_MEDICAL_PROVIDER')) {
            if($user->getMedicalProvider()->getIsRegistrationCompleted() != 1) {
                if($user->getMedicalProvider()->getRequestAssistance() == 1) {


                    return $this->redirectToRoute('registration_medical_provider_step'.$user->getMedicalProvider()->getRequestAssistanceStep());


                } else {
                    return $this->httpUtils->createRedirectResponse($request, $this->determineTargetUrl($request));
                }
            } else {
                return $this->httpUtils->createRedirectResponse($request, $this->determineTargetUrl($request));    
            }

        }
        else {
            return $this->httpUtils->createRedirectResponse($request, $this->determineTargetUrl($request));    
        }

    }
}

我想在登錄后根據上面的代碼我用戶的情況重定向到另一條路由，它給我以下錯誤：

錯誤：在AuthenticationSuccessHandler.php文件中調用未定義的方法redirectToRoute（）

如何從symfony中的登錄身份驗證成功處理程序文件中調用方法？

Answer 1

您不在控制器中，因此可以嘗試以下操作：

return $this->httpUtils->createRedirectResponse($request, 'registration_medical_provider_step'.$user->getMedicalProvider()->getRequestAssistanceStep());

Answer 2

您正在擴展DefaultAuthenticationSuccessHandler，因此此類中不存在redirectToRoute（）方法。

但是，您可以嘗試一下

$this->httpUtils->generateUri($request, 'your_target_path');

閱讀更多HttpUtils並查看此方法generateUri(Request $request, string $path)
