Getting User Feed From Facebook Without User Login

we are working on a web site that getting users' friends and users' feeds. Users can register via facebook connect. but 开发者_开发知识库we want to take user's feeds at any time. is that possible ? can we take feed information from facebook without user login.

You will have to take the permission from user for offline_access, only then you can get his feeds.

This would be very bad. There are users that have their feed on public, but generally, the user has to give explicit confirmation to allow you to use their feed.
