Strophe retrieving info before entering a room

I have a web XMPP client, based on Strophe, which connects to a private instance of Openfire server.

After connection to XMPP server I get all public rooms list.

Now I need a way to retrieve some info of those rooms without entering them.

In particular I need the current number of participants and eventually the list of them.

Solution

  • You can send a disco#items query to a MUC room to retrieve the list of current occupants, see XEP-0045 §6.5.

    The user hag66@shakespeare.lit/pda queries the room coven@chat.shakespeare.lit for its list of participants:

    <iq from='hag66@shakespeare.lit/pda'
    id='kl2fax27'
    to='coven@chat.shakespeare.lit'
    type='get'>
  <query xmlns='http://jabber.org/protocol/disco#items'/>
</iq>

    Room responds:

    <iq from='coven@chat.shakespeare.lit'
    id='kl2fax27'
    to='hag66@shakespeare.lit/pda'
    type='result'>
  <query xmlns='http://jabber.org/protocol/disco#items'>
    <item jid='coven@chat.shakespeare.lit/firstwitch'/>
    <item jid='coven@chat.shakespeare.lit/secondwitch'/>
  </query>
</iq>

    The server may refuse to answer if this information is private.
