I’m writing a bot in node.js using node-xmpp. So far it’s pretty straight forward except I’m having an issue with figuring out how google Talk handles it’s user authorization (when dealing with requesting to chat with someone NOT on your roster).
I’m catching all stanzas coming through and logging them to the console but there is no data coming from the user that is requesting authorization.
Any explanations of what I should be looking for or if this event even happens over the jabber protocol.
[appended] I know that technically when a subscription request is made a presence stanza is sent with the subscription request. I can’t see these coming over the wire using node-xmpp for some reason. Also, I need to find out a way to determine what presence requests are “pending” when my bot logs in. I thought (innacurrately) that they would be listed in the roster with some sort of flag, but that’s not correct.
Any help with finding out where to go from here would be useful.
Ok, I finally figured out how to get the subscription requests after they have been made. There isn’t much info on it out there so I’ll put together a blog post, but I feel that answering it here might be good as well.
I found that if I did a google roster query based on the below information:

example stanza:
The server would respond first with your pending server subscription “presence” stanzas
ex:
and then the rest of your roster’s “presence” stanzas. It’s important to note that your subscription “presence” stanzas don’t get sent to you from the server unless you do a roster query. I’m not sure why this is and why it’s not documented somewhere is beyond me. Anyways, at least I can get the list of people trying to get access to my bot now.
