我想在身份验证成功后更改默认身份验证过程。我创建了一个在身份验证成功后和重定向之前调用的服务。

namespace Pkr\BlogUserBundle\Handler;
use Doctrine\ORM\EntityManager;
use Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Log\LoggerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\Security\Http\Authentication\Response;

class AuthenticationSuccessHandler implements AuthenticationSuccessHandlerInterface
{

    protected $entityManager = null;
    protected $logger = null;
    protected $encoder = null;

    public function __construct(EntityManager $entityManager, LoggerInterface $logger, WpTransitionalEncoder $encoder)
    {
        $this->entityManager = $entityManager;
        $this->logger = $logger;
        $this->encoder = $encoder;
    }

    /**
    * This is called when an interactive authentication attempt succeeds. This
    * is called by authentication listeners inheriting from
    * AbstractAuthenticationListener.
    *
    * @param Request $request
    * @param TokenInterface $token
    *
    * @return Response never null
    */
    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $user = $token->getUser();
        $newPass = $request->get('_password');
        $user->setUserPassword($this->encoder->encodePassword($newPass, null));
        $this->entityManager->persist($user);
        $this->entityManager->flush();
        //do redirect
    }
}

在 services.yml

services:
    pkr_blog_user.wp_transitional_encoder:
        class: "%pkr_blog_user.wp_transitional_encoder.class%"
        arguments:
            cost: "%pkr_blog_user.wp_transitional_encoder.cost%"
            logger: @logger
    pkr_blog_user.login_success_handler:
        class: Pkr\BlogUserBundle\Handler\AuthenticationSuccessHandler
        arguments:
            entity_manager: @doctrine.orm.entity_manager
            logger: @logger
            encoder: @pkr_blog_user.wp_transitional_encoder

在 security.yml 中

firewalls:
    dev:
        pattern:  ^/(_(profiler|wdt)|css|images|js)/
        security: false

    secured_area:
        pattern:   ^/
        anonymous: ~
        form_login:
            login_path:  pkr_blog_admin_login
            check_path:  pkr_blog_admin_login_check
            success_handler: pkr_blog_user.login_success_handler
        logout:
            path: pkr_blog_admin_logout
            target: /

我想要实现的只是稍微改变默认行为，所以我想为什么不扩展DefaultAuthenticationSuccessHandler，添加一些东西onSuccessHandler()并调用parent::onSucessHandler(). 我试过了，问题是我不知道如何将安全参数（在 security.yml 中设置）添加到我的扩展类构造函数中。DefaultAuthenticationSuccessHandler 使用 HttpUtils 和 $options 数组：

/**
 * Constructor.
 *
 * @param HttpUtils $httpUtils
 * @param array     $options   Options for processing a successful authentication attempt.
 */
public function __construct(HttpUtils $httpUtils, array $options)
{
    $this->httpUtils   = $httpUtils;

    $this->options = array_merge(array(
        'always_use_default_target_path' => false,
        'default_target_path'            => '/',
        'login_path'                     => '/login',
        'target_path_parameter'          => '_target_path',
        'use_referer'                    => false,
    ), $options);
}

所以我的扩展类构造函数应该如下所示：

    // class extends DefaultAuthenticationSuccessHandler
    protected $entityManager = null;
    protected $logger = null;
    protected $encoder = null;

    public function __construct(HttpUtils $httpUtils, array $options, EntityManager $entityManager, LoggerInterface $logger, WpTransitionalEncoder $encoder)
    {
        $this->entityManager = $entityManager;
        $this->logger = $logger;
        $this->encoder = $encoder;
    }

将 HttpUtils 服务添加到 my 非常容易services.yml，但是 options 参数呢？

services:
    pkr_blog_user.wp_transitional_encoder:
        class: "%pkr_blog_user.wp_transitional_encoder.class%"
        arguments:
            cost: "%pkr_blog_user.wp_transitional_encoder.cost%"
            logger: @logger
    pkr_blog_user.login_success_handler:
        class: Pkr\BlogUserBundle\Handler\AuthenticationSuccessHandler
        arguments:
            httputils: @security.http_utils
            options: [] #WHAT TO ADD HERE ?
            entity_manager: @doctrine.orm.entity_manager
            logger: @logger
            encoder: @pkr_blog_user.wp_transitional_encoder

如果您只为您的应用程序定义了一个成功/失败处理程序，那么有一种更简单的方法可以做到这一点。您可以覆盖and而不是为success_handlerand定义新服务。failure_handlersecurity.authentication.success_handlersecurity.authentication.failure_handler

例子：

服务.yml

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

    security.authentication.failure_handler:
        class:  StatSidekick\UserBundle\Handler\AuthenticationFailureHandler
        arguments:  ["@http_kernel", "@security.http_utils", {}, "@logger"]
        tags:
            - { name: 'monolog.logger', channel: 'security' }

AuthenticationSuccessHandler.php

<?php
namespace StatSidekick\UserBundle\Handler;

use Symfony\Component\HttpFoundation\JsonResponse;
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;

class AuthenticationSuccessHandler extends DefaultAuthenticationSuccessHandler {

    public function __construct( HttpUtils $httpUtils, array $options ) {
        parent::__construct( $httpUtils, $options );
    }

    public function onAuthenticationSuccess( Request $request, TokenInterface $token ) {
        if( $request->isXmlHttpRequest() ) {
            $response = new JsonResponse( array( 'success' => true, 'username' => $token->getUsername() ) );
        } else {
            $response = parent::onAuthenticationSuccess( $request, $token );
        }
        return $response;
    }
}

AuthenticationFailureHandler.php

<?php
namespace StatSidekick\UserBundle\Handler;

use Psr\Log\LoggerInterface;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\HttpKernelInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Http\Authentication\DefaultAuthenticationFailureHandler;
use Symfony\Component\Security\Http\HttpUtils;

class AuthenticationFailureHandler extends DefaultAuthenticationFailureHandler {

    public function __construct( HttpKernelInterface $httpKernel, HttpUtils $httpUtils, array $options, LoggerInterface $logger = null ) {
        parent::__construct( $httpKernel, $httpUtils, $options, $logger );
    }

    public function onAuthenticationFailure( Request $request, AuthenticationException $exception ) {
        if( $request->isXmlHttpRequest() ) {
            $response = new JsonResponse( array( 'success' => false, 'message' => $exception->getMessage() ) );
        } else {
            $response = parent::onAuthenticationFailure( $request, $exception );
        }
        return $response;
    }
}

就我而言，我只是尝试设置一些东西，以便在尝试使用 AJAX 进行身份验证时获得 JSON 响应，但原理是相同的。

这种方法的好处是，无需任何额外工作，通常传递给默认处理程序的所有选项都应该正确注入。这是因为 SecurityBundle\DependencyInjection\Security\Factory 在框架中的设置方式：

protected function createAuthenticationSuccessHandler($container, $id, $config)
{
    ...
    $successHandler = $container->setDefinition($successHandlerId, new DefinitionDecorator('security.authentication.success_handler'));    
    $successHandler->replaceArgument(1, array_intersect_key($config, $this->defaultSuccessHandlerOptions));
    ...
}

protected function createAuthenticationFailureHandler($container, $id, $config)
{
    ...
    $failureHandler = $container->setDefinition($id, new DefinitionDecorator('security.authentication.failure_handler'));
    $failureHandler->replaceArgument(2, array_intersect_key($config, $this->defaultFailureHandlerOptions));
    ...
}

它专门寻找security.authentication.success_handler并将security.authentication.failure_handler您的配置中的选项合并到传入的数组中。我确信有一种方法可以为您自己的服务设置类似的东西，但我还没有研究过。

希望有帮助。

您可以在此文件中轻松查看默认安全侦听器的管理方式：

供应商/symfony/symfony/src/Symfony/Bundle/SecurityBundle/Resources/config/security_listeners.xml

例如， DefaultAuthenticationSuccessHandler 是这样注册的：

    <!-- Parameter -->

    <parameter key="security.authentication.success_handler.class">Symfony\Component\Security\Http\Authentication\DefaultAuthenticationSuccessHandler</parameter>

    <!-- Service -->

    <service id="security.authentication.success_handler" class="%security.authentication.success_handler.class%" abstract="true" public="false">
        <argument type="service" id="security.http_utils" />
        <argument type="collection" /> <!-- Options -->
    </service>

所以最后我们可以看到选项集合默认是空的！

options: {}会做的工作^^（认为一个集合在yaml中由{}表示）

要获得迄今为止最好的解决方案，请滚动到此答案的底部

好的，我终于让它以我想要的方式工作。问题是 Symfony2 在security.yml设置自定义处理程序时没有将配置数组从构造函数传递给构造函数。所以我所做的是：

1）我从security.yml

firewalls:
    dev:
      pattern:  ^/(_(profiler|wdt)|css|images|js)/
      security: false

secured_area:
    pattern:   ^/
    anonymous: ~
    form_login:
        login_path:  pkr_blog_admin_login
        check_path:  pkr_blog_admin_login_check
    logout:
        path: pkr_blog_admin_logout
        target: /

2)AuthenticationSuccessHandler扩展默认处理程序类，重新哈希用户密码，最后让默认处理程序完成其余工作。在构造函数中添加了两个新参数：

#/src/Pkr/BlogUserBundle/Handler/AuthenticationSuccessHandler.php
namespace Pkr\BlogUserBundle\Handler;
use Doctrine\ORM\EntityManager;
use Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Log\LoggerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Http\Authentication\DefaultAuthenticationSuccessHandler;
use Symfony\Component\Security\Http\Authentication\Response;
use Symfony\Component\Security\Http\HttpUtils;

class AuthenticationSuccessHandler extends DefaultAuthenticationSuccessHandler
{

    protected $entityManager = null;
    protected $logger = null;
    protected $encoder = null;

    public function __construct(
        HttpUtils $httpUtils,
        array $options,
        // new arguments below
        EntityManager $entityManager = null, # entity manager
        WpTransitionalEncoder $encoder = null
    )
    {
        $this->entityManager = $entityManager;
        $this->encoder = $encoder;
        parent::__construct($httpUtils, $options);
    }

    /**
    * This is called when an interactive authentication attempt succeeds. This
    * is called by authentication listeners inheriting from
    * AbstractAuthenticationListener.
    *
    * @param Request $request
    * @param TokenInterface $token
    *
    * @return Response never null
    */
    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $user = $token->getUser();
        if (preg_match('^\$P\$', $user->getUserPassword())) {
            $newPass = $request->get('_password');
            $user->setUserPassword($this->encoder->encodePassword($newPass, null));
            $this->entityManager->persist($user);
            $this->entityManager->flush();
        }
        return parent::onAuthenticationSuccess($request, $token);
    }
}

3）添加并更改了我的一些参数，services.yml以便我可以在我的编译器传递类中使用它们：

#/src/Pkr/BlogUserBundle/Resources/config/services.yml
parameters:
    pkr_blog_user.wp_transitional_encoder.cost: 20
    # password encoder class
    pkr_blog_user.wp_transitional_encoder.class: Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder
    # authentication success handler class
    pkr_blog_user.login_success_handler.class: Pkr\BlogUserBundle\Handler\AuthenticationSuccessHandler
    # entity manager service name
    pkr_blog_user.login_success_handler.arg.entity_manager: doctrine.orm.entity_manager
    # encoder service name
    pkr_blog_user.login_success_handler.arg.encoder: pkr_blog_user.wp_transitional_encoder

services:
    pkr_blog_user.wp_transitional_encoder:
        class: "%pkr_blog_user.wp_transitional_encoder.class%"
        arguments:
            cost: "%pkr_blog_user.wp_transitional_encoder.cost%"
            logger: @logger
    pkr_blog_user.login_success_handler:
        class: "%pkr_blog_user.login_success_handler.class%"

4) 创建了一个编译器传递类，该类RehashPasswordPass更改默认的身份验证成功处理程序并向构造函数添加一些参数：

#/src/Pkr/BlogUserBundle/DependencyInjection/Compiler/RehashPasswordPass.php
namespace Pkr\BlogUserBundle\DependencyInjection\Compiler;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Reference;

class RehashPasswordPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        if ($container->hasDefinition('security.authentication.success_handler')) {
            // definition of default success handler
            $def = $container->getDefinition('security.authentication.success_handler');
            // changing default class
            $def->setClass($container->getParameter('pkr_blog_user.login_success_handler.class'));
            $entityMngRef = new Reference(
                $container->getParameter("pkr_blog_user.login_success_handler.arg.entity_manager")
            );
            // adding entity manager as third param to constructor
            $def->addArgument($entityMngRef);
            $encoderRef = new Reference(
                $container->getParameter("pkr_blog_user.login_success_handler.arg.encoder")
            );
            // adding encoder as fourth param to constructor
            $def->addArgument($encoderRef);
        }
    }
}

5) 向容器构建器添加编译器传递：

#/src/Pkr/BlogUserBundle/PkrBlogUserBundle.php
namespace Pkr\BlogUserBundle;

use Pkr\BlogUserBundle\DependencyInjection\Compiler\RehashPasswordPass;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Bundle\Bundle;

class PkrBlogUserBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
        $container->addCompilerPass(new RehashPasswordPass());
    }
}

现在默认处理程序类已更改，但 symfony 仍会将配置从构造函数传递security.yml给构造函数以及编译器传递添加的两个新参数。

更好的方法

事件处理程序作为带有设置器的服务

#/src/Pkr/BlogUserBundle/Resources/config/services.yml
parameters:
    pkr_blog_user.wp_transitional_encoder.cost: 15
    # password encoder class
    pkr_blog_user.wp_transitional_encoder.class: Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder
    # authentication success handler class
    pkr_blog_user.authentication_success_handler.class: Pkr\BlogUserBundle\EventHandler\AuthenticationSuccessHandler


services:
    pkr_blog_user.wp_transitional_encoder:
        class: "%pkr_blog_user.wp_transitional_encoder.class%"
        arguments:
            cost: "%pkr_blog_user.wp_transitional_encoder.cost%"
            logger: @logger

    pkr_blog_user.authentication_success_handler:
        class: "%pkr_blog_user.authentication_success_handler.class%"
        calls:
            - [ setRequest, [ @request ]]
            - [ setEntityManager, [ @doctrine.orm.entity_manager ]]
            - [ setEncoder, [ @pkr_blog_user.wp_transitional_encoder ]]
        tags:
            - { name: kernel.event_listener, event: security.authentication.success , method: handleAuthenticationSuccess }

事件处理程序类

# /src/Pkr/BlogUserBundle/EventHandler/AuthenticationSuccessHandler.php
namespace Pkr\BlogUserBundle\EventHandler;
use Doctrine\ORM\EntityManager;
use Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder;
use Symfony\Component\EventDispatcher\Event;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Event\AuthenticationEvent;

class AuthenticationSuccessHandler {

    protected $entityManager = null;
    protected $encoder = null;

    public function setRequest(Request $request)
    {
        $this->request = $request;
    }

    public function setEntityManager(EntityManager $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function setEncoder(WpTransitionalEncoder $encoder)
    {
        $this->encoder = $encoder;
    }

    public function handleAuthenticationSuccess(AuthenticationEvent $event)
    {
        $token = $event->getAuthenticationToken();
        $user = $token->getUser();
        if (preg_match('^\$P\$', $user->getUserPassword())) {
            $newPass = $this->request->get('_password');
            $user->setUserPassword($this->encoder->encodePassword($newPass, null));
            $this->entityManager->persist($user);
            $this->entityManager->flush();
        }
    }

}

一切正常，无需编译器通过。为什么我一开始就没有想到...

呃，symfony 更新后它停止工作了

现在我得到异常：

ScopeWideningInjectionException: Scope Widening Injection detected: The definition "pkr_blog_user.authentication_success_handler" references the service "request" which belongs to a narrower scope. Generally, it is safer to either move "pkr_blog_user.authentication_success_handler" to scope "request" or alternatively rely on the provider pattern by injecting the container itself, and requesting the service "request" each time it is needed. In rare, special cases however that might not be necessary, then you can set the reference to strict=false to get rid of this error.

看来我需要将完整的容器传递给我的服务。所以我修改了services.yml事件处理程序类。

#/src/Pkr/BlogUserBundle/Resources/config/services.yml
parameters:
    pkr_blog_user.wp_transitional_encoder.cost: 15
    # password encoder class
    pkr_blog_user.wp_transitional_encoder.class: Pkr\BlogUserBundle\Service\Encoder\WpTransitionalEncoder
    # authentication success handler class
    pkr_blog_user.authentication_success_handler.class: Pkr\BlogUserBundle\EventHandler\AuthenticationSuccessHandler


services:
    pkr_blog_user.wp_transitional_encoder:
        class: "%pkr_blog_user.wp_transitional_encoder.class%"
        arguments:
            secure: @security.secure_random
            cost: "%pkr_blog_user.wp_transitional_encoder.cost%"

    pkr_blog_user.authentication_success_handler:
        class: "%pkr_blog_user.authentication_success_handler.class%"
        arguments:
            container: @service_container
        tags:
            - { name: kernel.event_listener, event: security.authentication.success , method: handleAuthenticationSuccess }

和事件处理程序

# /src/Pkr/BlogUserBundle/EventHandler/AuthenticationSuccessHandler.php
namespace Pkr\BlogUserBundle\EventHandler;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\Security\Core\Event\AuthenticationEvent;

class AuthenticationSuccessHandler
{

    /**
     * @var ContainerInterface
     */
    protected $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function handleAuthenticationSuccess(AuthenticationEvent $event)
    {
        $request = $this->container->get('request');
        $em = $this->container->get('doctrine.orm.entity_manager');
        $encoder = $this->container->get('pkr_blog_user.wp_transitional_encoder');
        $token = $event->getAuthenticationToken();
        $user = $token->getUser();
        if (preg_match('/^\$P\$/', $user->getUserPassword())) {
            $newPass = $request->get('_password');
            $user->setUserPassword($encoder->encodePassword($newPass, null));
            $em->persist($user);
            $em->flush();
        }
    }

}

它再次起作用。

不幸的是，通过使用success_handler安全配置中的选项，您无法提供扩展的自定义侦听器DefaultAuthenticationSuccessHandler。

直到这个问题得到解决：Symfony 问题 - [2.1][Security] Custom AuthenticationSuccessHandler

在那之前，最简单的解决方案是@dmccabe建议的：

security.authentication.success_handler只要您不需要多个防火墙的多个处理程序，全局覆盖就可以了。

如果您这样做（在撰写本文时），您必须编写自己的 Authentication Provider。

实际上，最好的方法是将默认身份验证处理程序扩展为服务

  authentication_handler:
      class: AppBundle\Service\AuthenticationHandler
      calls: [['setDoctrine', ['@doctrine']]]
      parent: security.authentication.success_handler
      public: false

AuthenticationHandler 类看起来像

class AuthenticationHandler extends DefaultAuthenticationSuccessHandler
{
    /**
     * @var Registry
     */
    private $doctrine;

    public function setDoctrine(Registry $doctrine)
    {
        $this->doctrine = $doctrine;
    }

    /**
     * This is called when an interactive authentication attempt succeeds. This
     * is called by authentication listeners inheriting from
     * AbstractAuthenticationListener.
     *
     * @param Request $request
     * @param TokenInterface $token
     *
     * @return Response never null
     */
    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        // do whatever you like here
        // ...


        // call default success behaviour
        return parent::onAuthenticationSuccess($request, $token);
    }
}
