JAXL is an open source Jabber XMPP Client library written in PHP. It provides a self titled class JAXL which implements XMPP protocol. It can be extended to write custom event handler for every message or presence received. Developers are using JAXL for developing real time applications.

However one thing which goes un-noticed is that JAXL can also be used to import Gtalk contacts of any user. This is infact one of the very first thing which JAXL class do, after successful authentication with the Gtalk servers i.e. import the authenticated user contact list. In this blog post I will demo a sample script to import any user contact list from google servers.

Importing Gtalk contacts using JAXL

  1. Download and extract jaxl-1.0.4.rar
  2. Edit config.ini.php and update credentials of the user whose contact list we are trying to import: 
      $key = array("prod"=>array("user"=>"mailsforabhinav",
                             "pass"=>"xxxxxx",
                             "host"=>"talk.google.com",
                             "port"=>5222,
                             "domain"=>"gmail.com"
                            ),
  3. Open jaxl.class.php and modify the code as below: 
        function setStatus() {
      // Set a custom status or use $this->status
      $this->sendStatus($this->status);
      print "Setting Status...\n";
      print_r($this->rosterlist); // Print the contact list on the console
      print "Done\n";
      exit;
    }
  4. Finally run from command line to retrieve gtalk contacts of the authenticated user. 
    php index.php

One can easily modify the above code to save user contacts in a database.
Also one can echo json_encode($this->rosterlist) in response to an Ajax call from the browser.
