Facebook API:如何获取FB登录用户的唯一ID?API 中的 ID 与 v2.0 中的“真实"用户 ID 不匹配 [英] Facebook API: How to get the FB login user's unique ID? ID from API doesn't match 'real' user ID in v2.0

问题描述

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user 
{
    self.profilePictureView.profileID = user.objectID;
    self.nameLabel.text = user.name;
    NSLog(@"My ID:%@", user.objectID);
}

我尝试使用上述代码打印用户 ID.我得到的是3176144783XXXXX.

I have tried to print the user id using the above code. And what I get is 3176144783XXXXX.

但是，我使用这个在线工具 http://findmyfacebookid.com/ 得到了另一个.结果是1000042591XXXXX.

However, I got a different one using this online tool http://findmyfacebookid.com/. The result is 1000042591XXXXX.

有人知道区别吗?为什么我的应用和findmyfacebookid.com"会收到同一用户的不同用户 ID?

Does anyone know the difference? Why do my app and 'findmyfacebookid.com' receive a different user ID for the same user?

注意:我的移动应用程序需要使用 FB 唯一 ID 来创建我自己的用户数据库.所以这就是我需要唯一 ID 的原因.

Note: My mobile app need to use the FB unique ID to create my own user database. So this is the reason I need a unique ID.

推荐答案

自 Facebook API v2.0 起，返回到您的应用的用户 ID 的范围仅限于您的应用(即，每个应用接收任何给定用户的不同标识符)- 您无法将该网站告诉您的内容与您调用 user.objectID 时您的应用收到的内容进行比较，因为它们是故意不同的字符串

Since v2.0 of the Facebook API the user IDs returned to your app are scoped to your app (i.e each app receives a different identifier for any given user) - you can't compare what that site is telling you to what your app received when you called user.objectID because they're intentionally different strings

使用返回到您的应用程序的 ID 作为您应用程序中用户的标识符 - 无需尝试查找真实"或旧"用户 ID - 您没有理由需要使用给定的用户 ID到任何其他应用 ID

Use the ID returned to your app as the identifier for users in your app - there's no need to try and find the 'real' or 'old' user ID - there's no reason for you to need to use the user ID given to any other app ID

And the app-scoped IDs are specifically discussed here, including a way for developers with multiple apps to corelate the IDs for users who use more than one of their apps : https://developers.facebook.com/docs/apps/upgrading#upgrading_v2_0_user_ids
