Question

我想在用户登录时跟踪一些数据（成功和失败），但我真的不知道该怎么做。

防火墙如下所示：

$app->register(new Silex\Provider\SecurityServiceProvider(), array(
    'security.firewalls' => array(
        'secured' => array(
            'pattern' => '^/',
            'anonymous' => true,
            'logout' => true,
            'form' => array('login_path' => '/login',
                            'check_path' => '/login_check',
                            ),
            'users' => $app->share(function () use ($app) {
                return $app["dao.identifiant"];
            }),
        ),
    ),
));

我发现我必须注册一项服务：

$app['security.authentication.success_handler.secured'] = $app->share(function ($app) {
    ...
});

我还创建了一个实现 AuthenticationSuccessHandlerInterface 的自定义类：

<?php

namespace myproject\Authentication;

use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;

class CustomAuthenticationSuccessHandler implements AuthenticationSuccessHandlerInterface
{

    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
       ...
    }
}

我有一个名为 Connection 的类，其中我有一个函数来记录我的数据库中的一些信息（如用户ID，连接的日期和时间，如果他失败或成功登录等等）。每当用户尝试登录时，如何设法调用此函数？

谢谢！

添加身份验证成功处理程序

namespace Your\Namespace;

use Symfony\Component\Security\Http\Authentication\DefaultAuthenticationSuccessHandler as BaseDefaultAuthenticationSuccessHandler;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;

class DefaultAuthenticationSuccessHandler extends BaseDefaultAuthenticationSuccessHandler
{
    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        // your actions

        return parent::onAuthenticationSuccess($request, $token);
    }
}

添加身份验证失败处理程序

namespace Your\Namespace;

use Symfony\Component\Security\Http\Authentication\DefaultAuthenticationFailureHandler as BaseDefaultAuthenticationFailureHandler;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Exception\AuthenticationException;

class DefaultAuthenticationFailureHandler extends BaseDefaultAuthenticationFailureHandler
{
    public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
    {
        // your actions

        return parent::onAuthenticationFailure($request, $exception);
    }
}

并在应用程序中注册它们

$app['security.authentication.success_handler.secured'] = $app->share(function () use ($app) {
    $handler = new \Your\Namespace\DefaultAuthenticationSuccessHandler(
        $app['security.http_utils'],
        $app['security.firewalls']['secured']['form']
    );
    $handler->setProviderKey('secured');

    return $handler;
});

$app['security.authentication.failure_handler.secured'] = $app->share(function () use ($app) {
    return new \Your\Namespace\DefaultAuthenticationFailureHandler(
        $app,
        $app['security.http_utils'],
        $app['security.firewalls']['secured']['form'],
        $app['logger']
    );
});

如何使用Silex框架实现自定义身份验证成功处理程序？
