LegacyClientStream
Handles XMPP-IM client connection stream. Both client and server side of the connection is supported. This class handles client SASL authentication, authorisation and resource binding. This class is not ready for handling of legacy Jabber servers, as it doesn't provide legacy authentication. :Ivariables: - `my_jid`: requested local JID. Please notice that this may differ from `me`, which is actual authorized JID after the resource binding. - `server`: server to use. - `port`: port number to use. - `password`: user's password. - `auth_methods`: allowed authentication methods. :Types: - `my_jid`: `pyxmpp.JID` - `server`: `str` - `port`: `int` - `password`: `str` - `auth_methods`: `list` of `str`

__init__(self,
jid,
password=None,
server=None,
port=None,
auth_methods=('sasl:DIGEST-MD5',),
tls_settings=None,
keepalive=0)
|
accept(self, sock)Accept an incoming client connection. [server only] :Parameters: - `sock`: a listening socket.
|
check_authzid(self, authzid, extra_info=None)Check authorization id provided by the client. [server only] :Parameters: - `authzid`: authorization id provided. - `extra_info`: additional information about the user from the authentication backend. This mapping will usually contain at least 'username' item. :Types: - `authzid`: unicode - `extra_info`: mapping :return: `True` if user is authorized to use that `authzid`. :returntype: `bool` |
choose_realm(self, realm_list)Choose authentication realm from the list provided by the server. [client only] Use domain of the own JID if no realm list was provided or the domain is on the list or the first realm on the list otherwise. :Parameters: - `realm_list`: realm list provided by the server. :Types: - `realm_list`: `list` of `unicode` :return: the realm chosen. :returntype: `unicode` |
connect(self, server=None, port=None)Establish a client connection to a server. [client only] :Parameters: - `server`: name or address of the server to use. Not recommended -- proper value should be derived automatically from the JID. - `port`: port number of the server to use. Not recommended -- proper value should be derived automatically from the JID. :Types: - `server`: `unicode` - `port`: `int`
|
do_bind(self, stanza)Do the resource binding requested by a client connected. [server only] :Parameters: - `stanza`: resource binding request stanza. :Types: - `stanza`: `pyxmpp.Iq` |
fix_in_stanza(self, stanza)Fix an incoming stanza. Ona server replace the sender address with authorized client JID. |
fix_out_stanza(self, stanza)Fix outgoing stanza. On a client clear the sender JID. On a server set the sender address to the own JID if the address is not set yet. |
get_password(self, username, realm=None, acceptable_formats=('plain',))Get a user password for the SASL authentication. :Parameters: - `username`: username used for authentication. - `realm`: realm used for authentication. - `acceptable_formats`: acceptable password encoding formats requested. :Types: - `username`: `unicode` - `realm`: `unicode` - `acceptable_formats`: `list` of `str` :return: The password and the format name ('plain'). :returntype: (`unicode`,`str`) |
get_realms(self)Get realms available for client authentication. [server only] :return: list of realms. :returntype: `list` of `unicode`
|
get_serv_host(self)Get the service host name for SASL authentication. :return: domain of the own JID. |
get_serv_name(self)Get the service name for SASL authentication. :return: domain of the own JID. |
get_serv_type(self)Get the server name for SASL authentication. :return: 'xmpp'. |
