Facebook user integration

I am having a problem in my facebook code. Currently, what I want to do is allow someone to set up a space in my app, and upload a file that can then be viewed by their friends. I cannot find any rea开发者_StackOverflow社区sonable way to do this. Is it currently possible to allow Person A to view Person B's data within my app? Please, any help would be appreciated.

You'll need to store uploaded files on your own server, and associate those files with the uploading Facebook user account. When a friend visits looking for files, you can query Facebook for their friend relationships to determine which files to display to them.
