IIRC, when a component sends an IQ without TO, ejabberd assumes the TO is the component himself.

Putting the user as the "to" address does create a item in the roster, but with N set for all fields (ignores the ask and subscription fields).

I don't see where that N comes from.

Some components (like transports) add contacts. You could install one of those, sniff the traffic they send to ejabberd, and reproduce it with your component.

There is an option that may be useful, look in the ejabberd Guide: service_check_from

Was this ever solved? Sending

error code 400

Yermo — Tue, 24 Mar 2009 02:15:01 +0000

I've got the external module going and I've set service_check_from in ejabberd.cfg.

I'm sending:

<iq type='set' id='add_f34827f1739e4af9580e5a209796b0da' from='yml@host'>
        <query xmlns='jabber:iq:roster'>
                <item jid='yermo@host'><group>Friends</group>
</item>
        </query>
</iq>

I'm getting an error:

<iq type='error' to='yml@host' id='add_f34827f1739e4af9580e5a209796b0da'>
        <query xmlns='jabber:iq:roster'>
                <item jid='yermo@host'><group>Friends</group>
</item>
        </query>
<error code='400' type='modify'><bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error></iq>

I'm sorry if this is a faq, but is there a list of error codes and their meanings somewhere I can refer to?

thanks,

thanks!

Cool, that's exactly what I needed to know.

I'll use that from my external component and see how it goes.

thanks!

Example stanza

Maybe.

2.3. Adding a Roster Item

In the account user@localhost add the contact tom@localhost. The client sends:

<iq from='user@localhost/Tka' type='set'>
     <query xmlns='jabber:iq:roster'>
       <item jid='tom@localhost' name='Tom'>
         <group>Friends</group>
       </item>
     </query>
   </iq>

Or, sending the stanza directly inside ejabberd:

ejabberd_router:route(
  {jid,"user","localhost","","user","localhost",""},
  {jid,"user","localhost","","user","localhost",""},
  {xmlelement,"iq",
    [{"type","set"}],
    [{xmlelement,"query",
         [{"xmlns","jabber:iq:roster"}],
         [{xmlelement,"item",
              [{"jid","tom@localhost"},{"name","Tom"}],
              [{xmlelement,"group",[],[{xmlcdata,"Friends"}]}]}]}]}).

If you send the stanza from an external component, you may be interested in the option service_check_from:
Component should be allowed to send packets on behalf of users

How to add items to mod_roster_odbc

Yermo — Wed, 14 Jan 2009 22:21:15 +0000

Is there a mechanism for adding roster items from an external source? (i.e. PHP script?) I'm assuming modifying the database directly is A Very Bad Thing(tm).

I was looking at mod_xmlrpc but it seems that's currently a hack.

Can I add items to a roster using a stanza from an external module? (I'm going to be writing one to intercept mod_service_log messages anyways)

Basically I want to be able to add roster items from a webpage.

Not implemented

mfoss — Wed, 14 Jan 2009 12:09:09 +0000

The roster management part of Web Admin is implemented in mod_roster and mod_roster_odbc.

However, mod_ctlextra (and the successor mod_admin_extra) implements only support for internal Mnesia storage (used by mod_roster).

I don't have any short term plan to implement that.
