How can I list all pubnub channels with active subscribers?

问题

I'd like to list all channels associated with a subscribe key that have active subscribers. Is there a way to do that with pubnub? I am using the JavaScript API if that makes any difference.

回答1:

PubNub Where Now API

Return a list of channels, associated with a subscribe key, where subscribers exist.

PUBNUB.where_now( { uuid : 'optional-uuid' }, function(data) {
    console.log(data);
} );

Note at the time of this posting, where_now() is only available in +3.6 SDK versions.
