XMPP iPhone的用户个人资料

Question

I am using XMPP for chatting in my iPhone application, I need to retrieve the profile of every user in buddy list, like phone number, street address etc.

How can I get started?

Answer 1

While XEP-54 can be used for this purpose, PLEASE do not spam the network by making vcard-temp requests for everyone on your roster every time your client logs in. Since you haven't told us what client library you're using, all we can do is provide you with the protocol you need to send:

<iq id='v1'
    type='get'>
  <vCard xmlns='vcard-temp'/>
</iq>

Note that XEP-54 is about to be obsoleted by XEP-292 , but it will take several years for that transition to take place.
