shim — Stanza Headers and Internet Metadata (XEP-0131)

This module provides support for XEP-0131 stanza headers. The following attributes are added by this module to the existing stanza classes:

aioxmpp.Message.xep0131_headers

A xso.Headers instance or None. Represents the SHIM headers of the stanza.

aioxmpp.Presence.xep0131_headers

A xso.Headers instance or None. Represents the SHIM headers of the stanza.

The attributes are available as soon as aioxmpp.shim is loaded.

class aioxmpp.SHIMService(client, **kwargs)

This service implements XEP-0131 feature advertisement.

It registers the http://jabber.org/protocol/shim node with the DiscoServer. It publishes the supported headers on that node as specified in the XEP.

To announce supported headers, use the register_header() and unregister_header() methods.

register_header(name)

Register support for the SHIM header with the given name.

If the header has already been registered as supported, ValueError is raised.

unregister_header(name)

Unregister support for the SHIM header with the given name.

If the header is currently not registered as supported, KeyError is raised.

Changed in version 0.8: This class was formerly known as aioxmpp.shim.Service. It is still available under that name, but the alias will be removed in 1.0.

class aioxmpp.shim.Service

Alias of SHIMService.

Deprecated since version 0.8: The alias will be removed in 1.0.

class aioxmpp.shim.xso.Headers(*args, **kwargs)

Represent stanza headers. The headers are accessible at the headers attribute.

headers

A multidict.CIMultiDict which provides access to the headers. The keys are the header names and the values are the values of the header. Both must be strings.
