Symfony 2自定义身份验证未使用正确的提供程序

我正在使用FOSRestBundle创建一个REST API。对于身份验证，我使用了一个标头，它随每个请求一起发送。它与这本食谱条目非常相似。

听众工作良好。一旦它调用了以下行，我就看不到任何调试或错误日志条目，它只是抛出一个AuthenticationError异常：$returnValue = $this->authenticationManager->authenticate($token);

我怀疑被调用的提供程序是main，而不是我添加的名为api的提供程序。

security.yml是唯一一个与食谱条目有很大偏差的配置文件：

security:
    encoders:
        Keobi'ModelBundle'Entity'User:
            algorithm: sha512
            iterations: 5000
            encode_as_base64: true
    role_hierarchy:
        ROLE_ADMIN:       [ROLE_USER, ROLE_ALLOWED_TO_SWITCH]
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]
    providers:
        main:
            entity: { class: KeobiModelBundle:User, property: email }
        api:
            entity: { class: KeobiModelBundle:Api, property: key }
    factories:
        - "%kernel.root_dir%/../src/Keobi/SecurityBundle/Resources/config/secrity_factories.yml"
    firewalls:
        dev:
            pattern:  ^/(_(profiler|wdt)|css|images|js)/
            security: false
        login:
            pattern:  ^/security/login$
            security: false
        api: # <- this is the firewall for my custom auth
            pattern: ^/api/
            #security: false
            api: true
            provider: api
        secured_area:
            pattern:    ^/(keobi|customer|security)/.*$
            form_login:
                check_path: /security/login_check
                login_path: /security/login
                success_handler: keobi_security.handler.authentication
                failure_handler: keobi_security.handler.authentication
                default_target_path: /
                target_path_parameter: _target_path
            logout:
                path:   /security/logout
                target: /security/login
                handlers: [keobi_security.handler.authentication]
            switch_user: { role: ROLE_ADMIN }
    access_control:
        - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/, roles: ROLE_ADMIN }

这是我的ApiListener.php文件：

<?php

  const SIGN_HEADER = 'x-keobi-signature';
  public function __construct(SecurityContextInterface $securityContext, AuthenticationManagerInterface $authenticationManager, Logger $logger, 'AppKernel $kernel)
  {
    $this->securityContext = $securityContext;
    $this->authenticationManager = $authenticationManager;
    $this->logger = $logger;
    $this->kernel = $kernel;
  }
  public function handle(GetResponseEvent $event)
  {
    $request = $event->getRequest();
    $kernel = $event->getKernel();
    if ($this->kernel->isDebug() && $request->query->has('_apikey') && $request->query->has('_apisecret') && $request->query->has('_ipaddress'))
    {
      $this->logger->debug('Debug key and secret used.');
      $token = new ApiToken();
      $created = time();
      $hash = hash('sha256', $request->query->get('_apikey') . $request->query->get('_apisecret') . strval($created));
      $token->key = $request->query->get('_apikey');
      $token->created = $created;
      $token->hash = $hash;
      $token->ipaddress = $request->query->get('_ipaddress');
    }
    elseif ($request->headers->has(self::AUTH_HEADER))
    {
      if (preg_match(self::AUTH_PATTERN, $request->headers->get(self::AUTH_HEADER), $matches))
      {
        $token = new ApiToken();
        $token->key = $matches['key'];
        $token->created = $matches['created'];
        $token->hash = $matches['hash'];
        $token->ipaddress = $request->getClientIp();
      }
    }
    if (isset($token))
    {
      $this->logger->debug($request->headers->get(self::AUTH_HEADER));
      try
      {
        $this->logger->debug(get_class($this->authenticationManager));
        $returnValue = $this->authenticationManager->authenticate($token);
        if ($returnValue instanceof TokenInterface)
          return $this->securityContext->setToken($returnValue);
        elseif ($returnValue instanceof Response)
          return $event->setResponse($returnValue);
      }
      catch (AuthenticationException $e)
      {
        $this->logger->err('Server failed to authenticate');
      }
    }
    # could not authenticate
    $response = new Response();
    $response->setStatusCode(403);
    $response->setContent('Could not be authenticated.');
    $event->setResponse($response);
  }
}

由于我发布了侦听器，侦听器是生成日志条目的对象，因此以下是尝试身份验证时发生的日志条目：
