Subscribing to all messages #237

Open johngeorgewright opened 8 years ago

johngeorgewright commented 8 years ago

Is there a way to listen to all messages? The reason I ask is because I'd like to make a monitoring tool for a WAMP setup. I've tried:

session.subscribe('', () => {}, {match: 'prefix'})

and...

session.subscribe('.', () => {}, {match: 'wildcard'})

Neither work.

The first one should work. The router has to allow that though, and the client needs to be authorized to receive the respective events.

Actually, if this is with Crossbar.io, then this might be a bug there: when you do a subscribe as above, this will include meta events under "wamp." (and "crossbar."), like "on_create_subscription", but since the subscription is only being setup right now, these meta events arrive at the client before the subscription request can even return successfully. AutobahnJS|Python will kill the connection ("protocol error") upon receiving an event with a subscription ID that it doesn't know about. I have a fix for that on a dev branch.
