Android Facebook 应用程序与 GAE 的集成

Question

我在思考如何解决下一个问题:

1. An Android App which I want to connect to facebook, and to a Server backend(Srv).
2. Server backend(Srv) which I want to connect to facebook.
3. The server will run a task that will Get all the Friends of the user(on fb), and the user Statuses(on Fb), and store them on it.

基本假设:

1. I use android as a Mobile device
2. Server is GAE
3. Entity key in GAE is the user’s FB-id
4. User Entity contains:
   1. User fb_id
   2. User verified list(FB_ID String)=> friends of the user that have the app) // maybe use HT?
   3. User statuses list(Status text, date, url)=> whatever I can get from a Status of a user in facebook..

主要问题:

1. Is the Data representation thought out? can it be better?
2. How do I handle a situation where two users which are connected to one another add the app at the same time- how can I avoid overlapping?
3. Should the device Authenticate itself, also with the GAE server?
4. How to Authenticate GAE with FB

算法:

安卓端:

 User login and get access token from FB
 Posting to my server(Srv) FB Token & myUserFBId // Should I use REST protocol or HTTP

发布？

服务器端:

  A Servlet handles the POST   
  {
    Query FB ->for the user's friends ids(into friendList = arrayList<FBItem))
    foreach FBItem item in friendList
    {
    //check which FB-ids are in my DB
      friendEntity = getKey(item.fb_id) 
      if(friendEntity != null)
      {
      // friend exists
         verifiedFriendsList.add(item.fb_id)  //verifiedFriendsList is ArrayList<String>
         friendEntity.getVerifiedFriendList().add(myUserFBId) 
      }
    }
    Query FB ->for the user's statuses(into statuses = arrayList<StatusItem))
    add new FBEntity(myUserFBId, verifiedFriendsList, statuses) to DB    }

谢谢

我没有做过这样的事情，但我认为你需要做

1. 要求用户验证您的应用程序以使用 FB- 阅读有关 Facebook 的 OAuth Api
2. 一旦您的应用通过足够权限的身份验证，您就可以根据您的要求获取用户数据。
3. 一旦获得数据，您就可以对其进行处理。

FB 上的 Oauth 就是您正在寻找的..
