Question

我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某些值。我想要完成一些数据库操作，所以我从配置文件中传递了@ doctrine.dbal.default_connection。这是我的配置文件，其中我覆盖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中，我的代码就是这样......

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;
}
}

当我直接执行某个控制器URL时，这是有效的。但当我执行我的应用程序主页时，如＃34; www.xyz.com/web"它引发了以下错误...

 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

知道如何解决这个问题吗？

您无需扩展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;
}
}

并配置标记为事件侦听器组件security.interactive_login

的服务

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：为什么不使用doctrine.orm.entity_manager代替doctrine.dbal.default_connection？（在我的sf中，我没有在php app/console container:debug命令中转储此服务）

在应用程序初始化时获取doctrine dbal是空的
