MongoDB部分匹配对象(MongoDB partial match on object)

 我试图在MongoDB中编写一个查询，根据字段是否部分匹配给定对象来提取某些对象。  
 我的MongoDB集合中的对象与此类似：  
  {
    permissions: {
      records: [
        "add",
      ]
    }
  }
 
 我希望能够通过查询给定用户的权限来检索相关对象。  
 例如，如果我查询了以下对象：  
  {
    permissions: {
      records: [
        "add",
        "delete"
      ],
      folders: [
        "delete",
      ]
    }
  }
 
 我想要返回与查询对象部分匹配的集合中的对象，这可能是这样的：  
  {
    permissions: {
      records: [
        "add",
      ]
    }
  },
  {
    permissions: {
      records: [
        "delete",
      ],
      folders: [
        "delete",
      ]
    }
  }
 
 如果有人可以给我任何指导，这将非常感谢！ 

I'm trying to write a query in MongoDB to pull out certain objects based on whether a field partially matches a given object. 
The objects in my MongoDB collection look something similar to this: 
  {
    permissions: {
      records: [
        "add",
      ]
    }
  }
 
I'd like to be able to retrieve the relevant objects by querying on the permissions of a given user. 
For example, if I queried with the following object: 
  {
    permissions: {
      records: [
        "add",
        "delete"
      ],
      folders: [
        "delete",
      ]
    }
  }
 
I'd want to return back the objects from the collection that partially matched the queried object, which would perhaps be these: 
  {
    permissions: {
      records: [
        "add",
      ]
    }
  },
  {
    permissions: {
      records: [
        "delete",
      ],
      folders: [
        "delete",
      ]
    }
  }
 
If anyone could give me any guidance on this, that'd be much appreciated!

 这不是我以前的修复类型，但事情似乎按预期工作，所以此时我只需要发货。  
 首先，事实证明我们的应用程序的旧版本正在请求offline_access。 我不知道。 我进入了我的FB应用程序的设置>高级，并启用了“删除offline_access权限”。 我现在正在取回持续两个月的令牌（ 查看facbeook令牌调试器 ）。  
 现在我已经找回了正确的标记类型，但在取消激活/过期时仍然有问题。 由于我现在正在取回2个月的令牌，因此我迫不及待地要过期，所以我的计划是通过进入我的帐户设置并取消授权来触发OAuthException。  
 在我的appDidBecomeActive中，我把[FBRequestConnection startForMeWithCompletionHandler：nil]简单地触发一个静默请求给FB，当它由于一个无效的会话/令牌而失败时，代码流将通过正确的路径运行，[FBSession renewSystemAuthorization]最终会被调用，这是我最需要的。 下次我通过FB登录到我的应用程序时，iOS允许我做的是，iOS再次提示我，理解我没有有效的标记了。 调用[FBSession renewSystemAuthorization]有效地告诉iOS，当我的应用程序下次请求访问时，打开Facebook并给我一个新的/刷新的令牌。  
 大多数情况下，一切正如预期的那样工作。 

This isn't the type of fix I was after, but things look to be working as expected, so at this point I just need to ship. 
First things first, it turns out that old versions of our app were requesting offline_access. I did not know that. I went in to my FB app's Settings > Advanced, and enabled "Remove offline_access permission." I am now getting back a token that lasts two months (check out the facbeook token debugger). 
Now that I'm getting back the correct kind of token, I still have a problem with getting back a valid token when it has been deactivated/expired. Since I'm now getting back a 2 month token, I can't wait for that to expire, so my plan was to trigger an OAuthException by going into my account's settings and deauthorizing it. 
In my appDidBecomeActive, I put [FBRequestConnection startForMeWithCompletionHandler:nil] to simply trigger a silent request to FB, and when that fails because of an invalid session/token, the code flow runs through the correct path and [FBSession renewSystemAuthorization] ends up getting called, which is ultimately what I was needing. What this allows iOS to do is the next time I go to Log in to my app through FB, iOS prompts me again, understanding I don't have a valid token anymore. Calling [FBSession renewSystemAuthorization] effectively tells iOS that the next time my app requests access, hit facebook and give me back a new/refreshed token. 
For the most part everything is working as expected now.
