How do I authorize a gdata client without using the gdata oauth2 workflow?

Question

I already have an access_token and refresh_token, but I can't figure out a way to create an authorized gdata client without going through the entire token generation workflow in gdata.

Answer 1

So I got this working finally. Here's how I did it:

    client = gdata.contacts.client.ContactsClient()
    credentials = gdata.gauth.OAuth2Token(client_id = 'client_id',
                                          client_secret = 'client_secret',
                                          scope = 'https://www.google.com/m8/feeds/',
                                          user_agent = auth.user_agent, # This is from the headers sent to google when getting your access token (they don't return it)
                                          access_token = auth.access_token,
                                          refresh_token = auth.refresh_token)

    credentials.authorize(client)
    contacts = client.get_contacts()
