我需要帮助在Symfony2项目中构建自定义身份验证。我已经阅读了symfony cookbook http://symfony.com/doc/2.3/cookbook/security/custom_authentication_provider.html并发现了很多关于自定义身份验证的问题，但当我尝试使用FOS用户捆绑包时，他们没有回答我的问题。我花了很多时间研究symfony身份验证过程，但无法理解我的错误。
所以我现在拥有：
这是我的代码：
用户实体类：
<?php
namespace Acme\UserBundle\Entity;
use Sonata\UserBundle\Entity\BaseUser as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use \Acme\BoardBundle\Entity\Card;
/**
* @ORM\Entity
* @ORM\HasLifecycleCallbacks
* @ORM\Table(name="fos_user")
*/
class User extends BaseUser
{
...
protected $card;
/**
* Set card
*
* @param \Acme\BoardBundle\Entity\Card $card
* @return Card
*/
public function setCard(\Acme\BoardBundle\Entity\Card $card)
{
$this->card = $card;
return $this;
}
/**
* Get card
*
* @return \Acme\BoardBundle\Entity\Card
*/
public function getCard()
{
return $this->card;
}
}
User.orm.xml：
<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="Acme\UserBundle\Entity\User" table="fos_user">
...
<many-to-one field="card" target-entity="Acme\BoardBundle\Entity\Card" inversed-by="users">
<join-column name="card" referenced-column-name="id" />
</many-to-one>
</entity>
</doctrine-mapping>
用户实体与卡实体有关系，卡实体有两个属性：卡号和PIN码。我登录后实际需要检查的属性。我的登录表单不仅包含用户名和密码字段，还包含卡号和PIN字段。
security.yml（我觉得我在防火墙配置方面有一些错误，但我无法理解错误）：
providers:
fos_userbundle:
id: fos_user.user_manager
firewalls:
dev:

always_use_default_target_path: true
default_target_path: ad_category
logout:

用户令牌：
<?php
namespace Acme\UserBundle\Security\Authentication\Token;
use Symfony\Component\Security\Core\Authentication\Token\AbstractToken;
class AcmeUserToken extends AbstractToken
{
public $userFIO;
public $cardNumber;
public $cardPIN;
public function __construct(array $roles = array())
{
parent::__construct($roles);
// If the user has roles, consider it authenticated
$this->setAuthenticated(count($roles) > 0);
}
public function getCredentials()
{
return '';
}
// поскольку токены проверяются при обработке каждом новом запросе клиента,
// нам необходимо сохранять нужные нам данные. В связи с этим “обертываем”
// унаследованные методы сериализации и десериализации.
public function serialize() {
$pser = parent::serialize();
//return serialize(array($this->social, $this->hash, $this->add, $pser));
return serialize(array($pser));
}
public function unserialize($serialized) {
//list($this->social, $this->hash, $this->add, $pser) = unserialize($serialized);
list($pser) = unserialize($serialized);
parent::unserialize($pser);
}
}
AcmeProvider.php（我的自定义身份验证提供程序）：
<?php
namespace Acme\UserBundle\Security\Authentication\Provider;
use Symfony\Component\Security\Core\Authentication\Provider\AuthenticationProviderInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Core\Exception\NonceExpiredException;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Acme\UserBundle\Security\Authentication\Token\AcmeUserToken;
class AcmeProvider implements AuthenticationProviderInterface
{
private $userProvider;
public function __construct(UserProviderInterface $userProvider)
{
$this->userProvider = $userProvider;
}
public function authenticate(TokenInterface $token)
{
$user = $this->userProvider->loadUserByUsername($token->getUsername());
if ($user) {
$authenticatedToken = new AcmeUserToken($user->getRoles());
$authenticatedToken->setUser($user);
return $authenticatedToken;
}
throw new AuthenticationException('The Acme authentication failed.');
}
public function supports(TokenInterface $token)
{
return $token instanceof AcmeUserToken;
}
}
工厂类AcmeFactory.php：
<?php
namespace Acme\UserBundle\DependencyInjection\Security\Factory;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Reference;
use Symfony\Component\DependencyInjection\DefinitionDecorator;
use Symfony\Component\Config\Definition\Builder\NodeDefinition;
use Symfony\Bundle\SecurityBundle\DependencyInjection\Security\Factory\SecurityFactoryInterface;
class AcmeFactory implements SecurityFactoryInterface
{
public function create(ContainerBuilder $container, $id, $config, $userProvider, $defaultEntryPoint)
{
$providerId = 'security.authentication.provider.acme.'.$id;
$container
->setDefinition($providerId, new DefinitionDecorator('acme.security.authentication.provider'))
->replaceArgument(0, new Reference($userProvider))
;
$listenerId = 'security.authentication.listener.acme.'.$id;
$listener = $container->setDefinition($listenerId, new DefinitionDecorator('acme.security.authentication.listener'));
return array($providerId, $listenerId, $defaultEntryPoint);
}
public function getPosition()
{
//return 'pre_auth';
return 'form';
}
public function getKey()
{
return 'acme';
}
public function addConfiguration(NodeDefinition $node)
{
}
}
在config.yml中配置用户提供程序和列表器：
services:
acme.security.authentication.provider:
class: Acme\UserBundle\Security\Authentication\Provider\AcmeProvider
abstract: true
arguments: ['']
public: false
security.authentication.listener.abstract:
tags:
- { name: 'monolog.logger', channel: 'security' }
arguments: [@security.context, @security.authentication.manager, @security.authentication.session_strategy, @security.http_utils, "knetik",@security.authentication.success_handler, @security.authentication.failure_handler, {}, @logger, @event_dispatcher]

# override application level success handler and re-route back
security.authentication.success_handler:
class: Symfony\Component\Security\Http\Authentication\DefaultAuthenticationSuccessHandler
arguments: ["@security.http_utils", {}]
tags:

# override application level failure handler and re-route back
security.authentication.failure_handler:
class: Symfony\Component\Security\Http\Authentication\DefaultAuthenticationFailureHandler
arguments: ["@http_kernel", "@security.http_utils", {}, "@logger"]
tags:
- { name: 'monolog.logger', channel: 'security' }
yamogu.security.authentication.listener:
class: Acme\UserBundle\Security\Authentication\Firewall\AcmeListener
parent: security.authentication.listener.abstract
abstract: true
arguments: ["@security.context", "@security.authentication.manager"]
public: false

我找到了解决问题的方法，但我采取了另一种方式。 我为form_login定义了一个成功的身份验证处理程序和失败处理程序，并将我的逻辑放在这里。如果用户输入了错误的用户名但是输入了正确的卡号和密码，我会在故障处理程反之亦然，如果用户输入了正确的用户名但错误的卡号和密码，那么我在成功验证失败时拒绝登录并手动注销他。

我可以看到这不是解决任务的最佳方式，但它对我有用。如果有人为我的解决方案提供了更好的解决方案或解决方案，请在此处添加！

您必须让您的安全上下文了解您的捆绑类中的工厂。在您的bundle类中执行以下操作：
class UserBundle extends Bundle
{
public function build(ContainerBuilder $container)
{
parent::build($container);
$extension = $container->getExtension('security');
$extension->addSecurityListenerFactory(new AcmeFactory());
}
public function getParent()
{
return 'FOSUserBundle';
}
}

Symfony中的安全层很难理解！我建议你按照blog post来了解Symfony的安全性。
