AnyEvent::XMPP::Ext::Registration - Handles all tasks of in band registration


   my $con = AnyEvent::XMPP::Connection->new (...);

   $con->reg_cb (stream_pre_authentication => sub {
      my ($con) = @_;
      my $reg = AnyEvent::XMPP::Ext::Registration->new (connection => $con);

      $reg->send_registration_request (sub {
         my ($reg, $form, $error) = @_;

         if ($error) {
            # error handling

         } else {
            my $af = $form->try_fillout_registration ("tester", "secret");

            $reg->submit_form ($af, sub {
               my ($reg, $ok, $error, $form) = @_;

               if ($ok) { # registered successfully!

               } else {   # error
                  if ($form) { # we got an alternative form!
                     # fill it out and submit it with C<submit_form> again



This module handles all tasks of in band registration that are possible and specified by XEP-0077. It's mainly a helper class that eases some tasks such as submitting and retrieving a form.


new (%args)

This is the constructor for a registration object.


This must be a AnyEvent::XMPP::Connection (or some other subclass of that) object.

This argument is required.

send_registration_request ($cb)

This method sends a register form request. $cb will be called when either the form arrived or an error occured.

The first argument of $cb is always $self. If the form arrived the second argument of $cb will be a AnyEvent::XMPP::Ext::RegisterForm object. If an error occured the second argument will be undef and the third argument will be a AnyEvent::XMPP::Error::Register object.

For hints how AnyEvent::XMPP::Ext::RegisterForm should be filled out look in XEP-0077. Either you have legacy form fields, out of band data or a data form.

See also try_fillout_registration in AnyEvent::XMPP::Ext::RegisterForm.

send_unregistration_request ($cb)

This method sends an unregistration request.

For description of the semantics of the callback in $cb plase look in the description of the submit_form method below.

send_password_change_request ($username, $password, $cb)

This method sends a password change request for the user $username with the new password $password.

For description of the semantics of the callback in $cb plase look in the description of the submit_form method below.

submit_form ($form, $cb)

This method submits the $form which should be of type AnyEvent::XMPP::Ext::RegisterForm and should be an answer form.

$con is the connection on which to send this form.

$cb is the callback that will be called once the form has been submitted and either an error or success was received. The first argument to the callback will be the AnyEvent::XMPP::Ext::Registration object, the second will be a boolean value that is true when the form was successfully transmitted and everything is fine. If the second argument is false then the third argument is a AnyEvent::XMPP::Error::Register object. If the error contained a data form which is required to successfully make the request then the fourth argument will be a AnyEvent::XMPP::Ext::RegisterForm which you should fill out and send again with submit_form.

For the semantics of such an error form see also XEP-0077.
