是否可以获取使用我的应用程序的每个人的用户信息

Question

If we didn't capture the information at signup is there a way to see who our users are?

Or if I have partial info on a user can I get more info they agreed to share?

Answer 1

When user signs up in your website via facebook,he gives you pemission to access basic info(and all other info for which you took pemission).

Facebook is all about pemissions.You ask the user to grant permission to access user data.In other words,You can access any data for which you have permission.

You can access the basic info like User name,Location,etc.(Which come under basic info) at any time(even if you didn't capture the information at signup ) with a valid access token and a user reference like user ID.

You can get the offline_access permission to publish or get user data even when user is offline.
