Php 使用令牌时Symfony Oauth2访问被拒绝

我跟随go将Oauth添加到我的Symfony Restful API中，问题是在我从服务器获得令牌后，我无法使其工作，只获得401，有人能帮助我吗？项目（上一次测试中的小更改除外）已启用。顺便说一句，我用的是symfony3.1

失败的测试：

  public function testCreate()
  {
      $clientManager = $this->client->getContainer()->get('fos_oauth_server.client_manager.default');
      $client = $clientManager->createClient();
      $client->setRedirectUris(array('http://www.example.com'));
      $client->setAllowedGrantTypes(array('token', 'authorization_code', 'password'));
      $clientManager->updateClient($client);
      $crawler = $this->client->request(
                       'POST',
                       '/oauth/v2/token',
                       array(),
                       array(),
                       array('CONTENT_TYPE' => 'application/json'),
                       '{
                         "grant_type":"password",
                         "client_id":"' . $client->getId() . '_' . $client->getRandomId() . '",
                         "client_secret":"' . $client->getSecret() . '",
                         "username": "Alvaro",
                         "password": "1231251265"
                        }'
                       );
      $this->assertEquals(200, $this->client->getResponse()->getStatusCode());
      $response = json_decode($this->client->getResponse()->getContent(), true);
      $this->assertTrue( strlen($response['access_token']) > 10 );
      $this->assertEquals( 'bearer', $response['token_type'] );
      $this->assertTrue( strlen($response['refresh_token']) > 10 );
      $this->assertEquals( 3600, $response['expires_in'] );
      $crawler = $this->client->request(
                                        'GET',
                                        '/businesses', //@TODO: Move this to a common route
                                        array(),
                                        array(),
                                        array('CONTENT_TYPE' => 'application/json'));
      $this->assertEquals(401, $this->client->getResponse()->getStatusCode());
      $crawler = $this->client->request(
                                        'GET',
                                        '/businesses', //@TODO: Move this to a common route
                                        array(),
                                        array(),
                                        array('CONTENT_TYPE' => 'application/json', 'Authorization:Bearer' => $response['access_token']));
      $this->assertEquals(200, $this->client->getResponse()->getStatusCode()); <-- failing assertion
