さて、これはささいなことではありませんが、できるだけ多くの情報を提供するように努めます。Symfony2.0のためにあなたがする必要があるいくつかの小さな変更があります、私の解決策は2.1のためです。コピー/貼り付けの問題がなく、タイプミスや構成の欠落がないことを願っています。AuthenticationProvider
まず、次のようなものを作成します。
<?php
namespace Acme\DemoBundle\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\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Encoder\EncoderFactory;
use Beryllium\CacheBundle\Cache;
use Acme\DemoBundle\Security\Authentication\Token\RestToken;
/**
* The Provider is the component of the authentication system that authenticates tokens.
*/
class LdapProvider implements AuthenticationProviderInterface
{
private $userProvider;
private $encoderFactory;
/**
* Constructor
* @param UserProviderInterface $userProvider
* @param String $cacheDir
* @param EncoderFactory $encoderFactory
*/
public function __construct(UserProviderInterface $userProvider, EncoderFactory $encoderFactory)
{
$this->userProvider = $userProvider;
$this->encoderFactory = $encoderFactory; // usually this is responsible for validating passwords
}
/**
* This function authenticates a passed in token.
* @param TokenInterface $token
* @return TokenInterface
* @throws AuthenticationException if wrong password or no username
*/
public function authenticate(TokenInterface $token)
{
if (!empty($token->username)) {
$user = $this->userProvider->loadUserByUsername($token->username);
$encoder = $this->encoderFactory->getEncoder($user);
if ($token->needsAuthentication && !$token->isLdapAuthenticated()) {
throw new AuthenticationException('Password wrong');
}
} else {
throw new AuthenticationException('No user');
}
$token->setUser($user);
$token->setAuthenticated(true);
return $token;
}
/**
* @inheritdoc
* @param TokenInterface $token
* @return Boolean
*/
public function supports(TokenInterface $token)
{
return $token instanceof RestToken;
}
}
サービスを(XMLで)登録します。
<service id="ldap.security.authentication.provider"
class="Acme\DemoBundle\Security\Authentication\Provider\LdapProvider" public="false">
<argument /> <!-- User Provider -->
<argument type="service" id="security.encoder_factory"/>
</service>
またはYAMLを使用する場合:
ldap.security.authentication.provider:
class: Acme\DemoBundle\Security\Authentication\Provider\LdapProvider
public: false
arguments:
- ~
- "@security.encoder_factory"
セキュリティファクトリを作成します。
<?php
namespace Acme\DemoBundle\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 LdapFactory implements SecurityFactoryInterface
{
public function create(ContainerBuilder $container, $id, $config, $userProvider, $defaultEntryPoint)
{
$providerId = 'security.authentication.provider.ldap.'.$id;
$container
->setDefinition($providerId, new DefinitionDecorator('ldap.security.authentication.provider'))
->replaceArgument(0, new Reference($userProvider))
;
$listenerId = 'security.authentication.listener.ldap.'.$id;
$listener = $container->setDefinition($listenerId, new DefinitionDecorator('ldap.security.authentication.listener'));
return array($providerId, $listenerId, $defaultEntryPoint);
}
public function getPosition()
{
return 'pre_auth';
}
public function getKey()
{
return 'ldap';
}
public function addConfiguration(NodeDefinition $node)
{}
}
バンドルに登録します。
<?php
namespace Acme\DemoBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Acme\DemoBundle\Security\Factory\LdapFactory;
class AcmeDemoBundle extends Bundle
{
public function build(ContainerBuilder $container)
{
parent::build($container);
$extension = $container->getExtension('security');
$extension->addSecurityListenerFactory(new LdapFactory());
}
}
独自のトークンを作成します。
namespace Acme\DemoBundle\Security\Authentication\Token;
use Symfony\Component\Security\Core\Authentication\Token\AbstractToken;
/**
* This is a class that represents a security token that is used for logged in users.
*/
class LdapToken extends AbstractToken
{
public $sessionId;
public $username;
public $password;
public $member;
public $needsAuthentication = true;
public function __construct(array $roles = array())
{
parent::__construct($roles);
}
public function getCredentials()
{
return '';
}
public function getRoles()
{
if ($this->getUser()) {
return $this->getUser()->getRoles();
} else {
return array();
}
}
public function isLdapAuthenticated()
{
return true; // Left as an exercise
}
}
次に、リスナーでそのトークンを作成する必要があります。たとえば、次のようになります。
<?php
namespace Acme\ApiBundle\Security\Firewall;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpKernel\Event\FilterResponseEvent;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Http\Firewall\ListenerInterface;
use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Core\SecurityContextInterface;
use Symfony\Component\Security\Core\Authentication\AuthenticationManagerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\EventDispatcher\EventDispatcher;
use Acme\DemoBundle\Security\Authentication\Token\LdapToken;
use Symfony\Component\HttpFoundation\Session\Attribute\AttributeBag;
/**
* Class that will listen for log ins and then authorize the user.
*/
class LdapListener implements ListenerInterface
{
/**
* A security context
* @var SecurityContextInterface
*/
protected $securityContext;
/**
* A authentication manager that we will be able to authenticate against
* @var AuthenticationManagerInterface
*/
protected $authenticationManager;
/**
* Constructor
*
* @param SecurityContextInterface $securityContext
* @param AuthenticationManagerInterface $authenticationManager
*/
public function __construct(SecurityContextInterface $securityContext,
AuthenticationManagerInterface $authenticationManager
) {
$this->securityContext = $securityContext;
$this->authenticationManager = $authenticationManager;
}
/**
* This function is handling the authentication part.
*
* @param GetResponseEvent $event
* @return
*/
public function handle(GetResponseEvent $event)
{
$request = $event->getRequest();
$token = new LdapToken();
// now populate it with whatever information you need, username, password...
try {
$returnValue = $this->authenticationManager->authenticate($token);
if ($returnValue instanceof TokenInterface) {
if ($token->needsAuthentication) {
if ($event->hasResponse()) {
$response = $event->getResponse();
} else {
$response = new Response();
$event->setResponse($response);
}
}
return $this->securityContext->setToken($returnValue);
} elseif ($returnValue instanceof Response) {
return $event->setResponse($response);
}
} catch (AuthenticationException $e) {
// Do nothing in this case. We are returning a 401 below
}
$response = new Response('UNAUTHORIZED');
$response->setStatusCode(HTTPCodes::HTTP_UNAUTHORIZED);
$event->setResponse($response);
}
}
そしてそれをサービスとしても登録します(XMLを使用):
<service id="ldap.security.authentication.listener"
class="Acme\DemoBundle\Security\Firewall\RestListener" public="false">
<argument type="service" id="security.context"/>
<argument type="service" id="security.authentication.manager" />
</service>
またはYAML:
ldap.security.authentication.listener:
class: Acme\DemoBundle\Security\Firewall\RestListener
public: false
arguments:
- "@security.context"
- "@security.authentication.manager"
それがあなたを始めることを願っています!
