Facebooker talk - Mar 2008 - How to get a facebook session for desktop applications (or unit tests?)

Normally, in a rails app, all one would have to do is call
set_facebook_session, or the ensure_* filters to get a valid session.
I''ve been looking through the sessions code to figure out how to get a
valid session for desktop applications (or unit tests)--basically
outside of rails controller.

As far as I can ascertain, you should just be able to do this:

require ''facebooker''

sess = Facebooker::Session.create
sess.secure!

Since secure! calls auth_token to get authentication token on its own
if it hadn''t already.  But instead this throws a
Facebooker::Session::MissingOrInvalidParameter:

=> #<Facebooker::Session:0xb66756e0
@secret_key="829bbe2f0255043cc906b064a9239c07",
@api_key="98519f7e0ed4e6e8ad01bfb2864c1e3c">
>> sess.secure!
Facebooker::Session::MissingOrInvalidParameter: Invalid parameter

/home/wil/proj/3cgworkspace/mobtropolis/vendor/plugins/facebooker/lib/facebooker/session.rb:137:in
`secure!''
        from (irb):14

I think I''m missing something fundamental.  I''ve looked
through the fb
developer docs and the facebooker code, but I"m coming up short.  Can
anyone set me straight?  Thanks.
