  我也有这个问题 . 我使用了security.yml并在使用的注册操作中：

  $redirectUrl = $request->getSession()->get('_security.account.target_path');
  

  请享用 .

  Symfony使用HTTP Referer header将用户重定向回他们来自的页面..即引用者

  您可以使用security.yml中的安全配置 use_referer: true 进行设置，details here

  您可以使用以下命令从控制器访问referer标头：

  $referer = $request->headers->get('referer');
  

  Note Headers 拼写错误，其引用（一个r）

  Carrie Kendall的解决方案有效，谢谢！

  这是Symfony中的完整实现：

  services.yml：

  login_handler:
      class: Project\BaseBundle\Service\loginHandler
      arguments: ['@router', '@doctrine.orm.entity_manager', '@service_container']
  

  在Project \ BaseBundle \ Service \ loginHandler中：

  namespace Project\BaseBundle\Service;
  
  use Symfony\Component\HttpFoundation\Request;
  use Symfony\Component\HttpFoundation\RedirectResponse;
  use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
  use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
  use Symfony\Component\Routing\RouterInterface;
  use Doctrine\ORM\EntityManager;
  
  
  class loginHandler implements AuthenticationSuccessHandlerInterface {
  
      private $router;
      private $container;
      private static $key;
  
      public function __construct(RouterInterface $router, EntityManager $em, $container) {
  
          self::$key = '_security.secured_area.target_path';
  
          $this->router = $router;
          $this->em = $em;
          $this->session = $container->get('session');
  
      }
  
      public function onAuthenticationSuccess( Request $request, TokenInterface $token ) {
  
          $user_entity = $token->getUser();
  
          if( !$user_entity->getChangePassword() ) {
  
              $route = $this->router->generate('BaseBundle_home_page');
  
          } else {
  
              $this->session->getFlashBag()->add('error', 'Your password must be changed now');
  
              $route = $this->router->generate('BaseBundle_account_page');
  
          }
  
          //check if the referer session key has been set
          if ($this->session->has( self::$key )) {
  
              //set the url based on the link they were trying to access before being authenticated
              $route = $this->session->get( self::$key );
  
              //remove the session key
              $this->session->remove( self::$key );
              //if the referer key was never set, redirect to a default route
  
          } else{
  
              $url = $this->generateUrl('BaseBundle_home_page');
  
              return new RedirectResponse($route);
  
          }
  
          return new RedirectResponse($route);
  
      }
  }

  这是可能的，您可以在会话中访问引用链接（如果 use_referer 设置为 true ，则使用该链接） .

  例如，如果您的 form_login （在防火墙配置中）有一个 success_handler 服务，它根据某些条件（通常是角色）重定向用户，但是如果设置了用户，则您希望将用户重定向到引荐来源链接，您可以访问引荐来源链接像这样：

  $key = '_security.main.target_path'; #where "main" is your firewall name
  
  //check if the referrer session key has been set 
  if ($this->container->get('session')->has($key)) {
      //set the url based on the link they were trying to access before being authenticated
      $url = $this->container->get('session')->get($key);
  
      //remove the session key
      $this->container->get('session')->remove($key);
  }
  //if the referrer key was never set, redirect to a default route
  else{
      $url = $this->router->generate('member_home');
  }
  
  return new RedirectResponse($url);
  

  使用标头获取引用者（即 $request->headers->get('referer') ）在这种情况下不起作用，因为它将始终返回登录链接 .
