我正在为我的模型实现一个ACL系统,我想将公共代码提取到一个常见的Helper类中.我找不到任何关于如何正确做这样的事情的例子,但我经常发现有必要这样做.

例如,假设在我的控制器中我有一大块代码(从文档中获取):

      // creating the ACL
      $aclProvider = $this->get('security.acl.provider');
      $objectIdentity = ObjectIdentity::fromDomainObject($asset);
      $acl = $aclProvider->createAcl($objectIdentity);

      // retrieving the security identity of the currently logged-in user
      $securityContext = $this->get('security.context');
      $user = $securityContext->getToken()->getUser();
      $securityIdentity = UserSecurityIdentity::fromAccount($user);

      // grant owner access
      $acl->insertObjectAce($securityIdentity, MaskBuilder::MASK_OWNER);
      $aclProvider->updateAcl($acl); 

我更愿意拥有以下内容:

      $this->get('my_helpers')->bindUserToObject($asset, MaskBuilder::MASK_OWNER);

我应该如何实施'my_helpers'服务？我很确定这将是一项服务,但我仍然觉得"服务"的概念有点令人困惑.
