so I'm new to the Graph API, and the one thing I'm not understanding is how the auth tokens work. The test app I want to write is a simple ruby program that can make HTTP requests to facebook to do things, like perhaps post messages from a message queue I have generated. I don't want to have a front-end or anything like that. I don't see any way to just hit an endpoint with my facebook username and password and get an authorization token back. Is that not a supported functionality? How might I accomplish what I want, which is essentially automated control of my facebook account via a ruby app.
I see I can generate a token via the API Explorer, but that token is short lived.
