Question

我确实按照cookbook来实现自定义身份验证提供程序，但authenticate（）不会从WsseProvider执行。

我检查了supports（）函数，它可以正常工作。

PHP Storm使用authenticate函数给出以下错误：

声明必须与AuthenticationManagerInterface-＆gt; authenticate兼容（令牌：\ Symfony \ Component \ Security \ Core \ Authentication \ TokenInterface）

但是我已经按照食谱中的说明导入了TokenInterface：

use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;

所以PHP Storm要求我改为：

use Symfony\Component\Security\Core\Authentication\TokenInterface;

但是使用这个supports（）并不执行。

任何人都知道我为什么会收到此错误，和/或为什么验证不执行？我按照烹饪书中的说明完全按照步骤进行操作。

以下是代码：

<?php

namespace AppBundle\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; //Using this authenticate doesnt work
//use Symfony\Component\Security\Core\Authentication\TokenInterface; //Using this supports doesnt work
use AppBundle\Security\Authentication\Token\WsseUserToken;
use Symfony\Component\Security\Core\Util\StringUtils;

class WsseProvider implements  AuthenticationProviderInterface
{
    private $userProvider;
    private $cacheDir;

    public function __construct(UserProviderInterface $userProvider, $cacheDir)
    {
        $this->userProvider = $userProvider;
        $this->cacheDir     = $cacheDir;
    }

    public function supports(TokenInterface $token)
    {
        return $token instanceof WsseUserToken;
    }

    public function authenticate(TokenInterface $token)
    {
        die('authenticate is executed'); //This doesnt fire

        $user = $this->userProvider->loadUserByUsername($token->getUsername());

        if ($user && $this->validateDigest($token->digest, $token->nonce, $token->created, $user->getPassword())) {
            $authenticatedToken = new WsseUserToken($user->getRoles());
            $authenticatedToken->setUser($user);

            return $authenticatedToken;
        }

        throw new AuthenticationException('The WSSE authentication failed.');
    }

    /**
     * This function is specific to Wsse authentication and is only used to help this example

     */
    protected function validateDigest($digest, $nonce, $created, $secret)
    {
        // Check created time is not in the future
        if (strtotime($created) > time()) {
            return false;
        }

        // Expire timestamp after 5 minutes
        if (time() - strtotime($created) > 300) {
            return false;
        }

        // Validate that the nonce is *not* used in the last 5 minutes
        // if it has, this could be a replay attack
        if (file_exists($this->cacheDir.'/'.$nonce) && file_get_contents($this->cacheDir.'/'.$nonce) + 300 > time()) {
            throw new NonceExpiredException('Previously used nonce detected');
        }
        // If cache directory does not exist we create it
        if (!is_dir($this->cacheDir)) {
            mkdir($this->cacheDir, 0777, true);
        }
        file_put_contents($this->cacheDir.'/'.$nonce, time());

        // Validate Secret
        $expected = base64_encode(sha1(base64_decode($nonce).$created.$secret, true));

        return StringUtils::equals($expected, $digest);
    }

}

不执行Symfony2身份验证
