我正在使用身份验证成功处理程序在每次成功登录时填充会话中的一些值。我想要完成一些数据库操作，所以我从我的配置文件中传递了@doctrine.dbal.default_connection。这是我的配置文件，我在其中覆盖了 success_handler 函数。

services:     
    security.authentication.success_handler:
    class:  XYZ\UserBundle\Handler\AuthenticationSuccessHandler
    arguments:  ["@security.http_utils", {}, @doctrine.dbal.default_connection]
    tags:
        - { name: 'monolog.logger', channel: 'security' }

在 AuthenticationSuccessHandler.php 我的代码是这样的......

namespace Sourcen\UserBundle\Handler;

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


class AuthenticationSuccessHandler extends DefaultAuthenticationSuccessHandler {

private $connection;

public function __construct( HttpUtils $httpUtils, array $options, Connection $dbalConnection ) {
    $this->connection = $dbalConnection;
    parent::__construct( $httpUtils, $options );
}

public function onAuthenticationSuccess( Request $request, TokenInterface $token ) {
    $response = parent::onAuthenticationSuccess( $request, $token );
    // DB CODE GOES  
    return $response;
}
}

当我直接执行一些控制器 URL 时，这是有效的。但是当我执行我的应用程序主页 URL 时，例如“www.xyz.com/web”，它会引发以下错误......

 Catchable fatal error: Argument 3 passed to XYZ\UserBundle\Handler\AuthenticationSuccessHandler::__construct() must be an instance of Doctrine\DBAL\Connection, none given, called in /opt/lampp/xyz/app/cache/prod/appProdProjectContainer.php on line 1006 and defined in /opt/lampp/xyz/src/Sourcen/UserBundle/Handler/AuthenticationSuccessHandler.php on line 18

知道如何解决吗？

您不需要扩展DefaultAuthenticationSuccessHandler类。

尝试定义您的服务类，如：

namespace XYZ\UserBundle\Handler;

use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Doctrine\DBAL\Connection;


class AuthenticationSuccessHandler  {

private $connection;

public function __construct( Connection $dbalConnection ) {
    $this->connection = $dbalConnection;
}

public function onAuthenticationSuccess( InteractiveLoginEvent $event ) {
    $user = $event->getAuthenticationToken()->getUser();

    // DB CODE GOES  
    return $response;
}
}

并将您的服务配置为事件侦听器组件security.interactive_login

services:     
    security.authentication.success_handler:
    class:  XYZ\UserBundle\Handler\AuthenticationSuccessHandler
    arguments:  [@doctrine.dbal.default_connection]
    tags:
        - { name: 'kernel.event_listener', event: 'security.interactive_login'. method:'onAuthenticationSuccess' }

PS：你为什么不使用doctrine.orm.entity_manager代替doctrine.dbal.default_connection？（在我的科幻小说中，我没有在php app/console container:debug命令中转储此服务）
