Facebook javascript v2.0通知应用程式特定使用者编号。 但是如果任何旧用户卸载应用程序,并且在更改应用程序版本后再次重新安装该应用程序会发生什么?
Facebook javascript v2.0 informs app specific user id. But what will happen if any old user uninstall an application and again re install that application after changing the application version?
他们是否会有新的用户ID ?
Will they have new userid?
推荐答案他将获得相同的ID,因此您仍然可以识别返回的用户。我只是用一个应用来测试它,一定要:授权用户,打电话给我,删除应用程序,再次授权用户,打电话给我/我>同一个ID。
He will get the same ID, so you can still identify returning users. I just tested it with an App to be sure: Authorize user, call /me, remove App, authorize user again, call /me > same ID.
编辑:我们刚才在另一个主题中讨论过: Facebook API 2.1 - 关于邀请朋友和应用范围的用户ID
We just discussed this in another thread: Facebook API 2.1 - About Invite Friends And App-scoped User IDs
似乎如果用户可以更改作用域ID经过很长一段时间,您的应用程式已被盗用并获得授权。但是如果用户长时间不使用App - 数据隐私和内容,您将不得不删除用户数据。
It seems that the Scoped ID may change if the user deauthorized your App and authorizes it after a long time. But you would have to delete the user data anyway if the user does not use the App for a long time - data privacy and stuff.
