Logging into Facebook without a Browser
What you are trying to do is not possible. You are going to have to use a browser to get an access token one way or another. You cannot collect username and passwords (a big violation of Facebook's TOS). If you need a script that runs without user interaction you will still need to use a browser to authenticate, but once you have the user's token you can use it without their direct interaction. You must request the "offline_access" permission to gain an access token that does not expire. You can save this token and then use it for however long you need.
I'm working on a script currently that needs to pull information down from a specific user's wall. The only problem is that it requires authentication, and the script needs to be able to run without any human interference. Unfortunately all I can find thus far tells me that I need to register an application, and then do the whole FB Connect dance to pull off what I want. Problem is that requires browser interaction, which I'm trying to avoid.
I figured I could probably just use httplib2, and login this route. I got that to work, only to find that with that method I still don't get an "access_token" in any retrievable method. If I could get that token without launching a browser, I'd be completely set. Surely people are crawling feeds and such without using FB Connect right? Is it just not possible, thus why I'm hitting so many road blocks? Open to any suggestions you all might have.
