使用simple_form身份验证器的Symfony2 + FOS

标签: php symfony authentication fosuserbundle

我使用FriendsOfSymfony UserBundle。当我将防火墙中的所有内容设置为form_login时,它会起作用,但如果我将其设置为simple_form以使用Custom Authenticator,则即使帐户被锁定或已停用,它也会让我登录。我想检查用户是否来自正确的IP,这就是我创建自定义身份验证器的原因,但似乎来自FOS的某些身份验证不会以这种方式处理。如何在保留FOS UserBundle的完整功能的同时将simple_form与自定义身份验证器一起使用?

除了标准之外,还有其他方法可以实现其他身份验证吗?也许我做错了什么?我知道我可以更正我的身份验证器的代码以检查锁定/启用等,但我想 - 因为它实际上已经在FOS中完成了 - 我为什么要这样做?

编辑:此外,我注意到当我使用simple_form时,类Symfony\Component\Security\Core\User\UserChecker的方法无法被调用。

以下是我的验证码和security.yml代码:

config.yml

    login_authenticator:
        class:     Forex\AlchemyBundle\Security\LoginAuthenticator
        arguments: ["@security.encoder_factory"]

                provider: fos_userbundle
                csrf_provider: form.csrf_provider
            logout:       true
            anonymous:    true

        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/admin/, role: ROLE_ADMIN }
        - { path: ^/.*, roles: ROLE_USER }

LoginAuthenticator

<?php

namespace Forex\AlchemyBundle\Security;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authentication\SimpleFormAuthenticatorInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;

use Symfony\Component\Security\Core\Exception\AuthenticationException;

class LoginAuthenticator implements SimpleFormAuthenticatorInterface
{
    private $encoderFactory;

    public function __construct(EncoderFactoryInterface $encoderFactory)
    {
        $this->encoderFactory = $encoderFactory;
    }

    public function authenticateToken(TokenInterface $token, UserProviderInterface $userProvider, $providerKey)
    {
        try {
            $user = $userProvider->loadUserByUsername($token->getUsername());
        } catch (UsernameNotFoundException $e) {
            throw new AuthenticationException('Invalid username or password');
        }

        $encoder = $this->encoderFactory->getEncoder($user);
        $passwordValid = $encoder->isPasswordValid(
            $user->getPassword(),
            $token->getCredentials(),
            $user->getSalt()
        );

        if ($passwordValid) {

            $request = Request::createFromGlobals();

            $current_ip = $request->server->get('REMOTE_ADDR');

            $user->setLoggedIP($current_ip);

            if (!$user->isValidIP()) {
                throw new AuthenticationException(
                    "You cannot login from your location.",
                    100
                );
            }

            return new UsernamePasswordToken(
                $user,
                $user->getPassword(),
                $providerKey,
                $user->getRoles()
            );
        } else {
            // TODO: Check if there weren't too many tries to login
        }

        throw new AuthenticationException('Invalid username or password');
    }

    public function supportsToken(TokenInterface $token, $providerKey)
    {
        return $token instanceof UsernamePasswordToken
            && $token->getProviderKey() === $providerKey;
    }

    public function createToken(Request $request, $username, $password, $providerKey)
    {
        return new UsernamePasswordToken($username, $password, $providerKey);
    }

}

我遇到了同样的问题。以下是我解决它的方法。

您必须在Authenticator中的authenticateToken()方法中调用UserChecker类的checkPreAuth()和checkPostAuth()方法。

这样做是这样的:

1)配置user_checker服务:

services:
    app.user_checker:
        class: AppBundle\Security\UserChecker

2)将autenticator配置为服务并注入user_checker服务:

services:
    app.my_authenticator:
        class:     AppBundle\Security\MyAuthenticator
        arguments: ["@app.user_checker", "@security.password_encoder"]

3)现在你可以在authenticateToken()上调用checkPreAuth()和checkPostAuth()

无论如何,我认为symfony方法是正确的,因为在我的情况下,你需要在simple_form中执行不同于login_form的检查。
