Module twisted.protocols.msn
MSNP8 Protocol (client only) - semi-experimental
Stability: unstable.
This module provides support for clients using the MSN Protocol
(MSNP8). There are basically 3 servers involved in any MSN session:
Dispatch server
The DispatchClient class handles connections to the dispatch server,
which basically delegates users to a suitable notification server.
You will want to subclass this and handle the gotNotificationReferral
method appropriately.
Notification Server
The NotificationClient class handles connections to the notification
server, which acts as a session server (state updates, message
negotiation etc...)
Switcboard Server
The SwitchboardClient handles connections to switchboard servers which
are used to conduct conversations with other users.
There are also two classes (FileSend and FileReceive) used for file
transfers.
Clients handle events in two ways.
-
each client request requiring a response will return a Deferred,
the callback for same will be fired when the server sends the
required response
-
Events which are not in response to any client request have
respective methods which should be overridden and handled in an
adequate manner
Most client request callbacks require more than one argument, and
since Deferreds can only pass the callback one result, most of the time
the callback argument will be a tuple of values (documented in the
respective request method). To make reading/writing code easier,
callbacks can be defined in a number of ways to handle this 'cleanly'.
One way would be to define methods like: def callBack(self, (arg1, arg2,
arg)): ... another way would be to do something like:
d.addCallback(lambda result: myCallback(*result)).
If the server sends an error response to a client request, the errback
of the corresponding Deferred will be called, the argument being the
corresponding error code.
NOTE: Due to the lack of an official spec for MSNP8, extra
checking than may be deemed necessary often takes place considering the
server is never 'wrong'. Thus, if gotBadLine (in any of the 3 main
clients) is called, or an MSNProtocolError is raised, it's probably a
good idea to submit a bug report. ;) Use of this module requires that
PyOpenSSL is installed.

Classes |
DispatchClient |
This class provides support for clients connecting to the dispatch
server |
FileReceive |
This class provides support for receiving files from contacts. |
FileSend |
This class provides support for sending files to other contacts. |
MSNContact |
This class represents a contact (user). |
MSNContactList |
This class represents a basic MSN contact list. |
MSNEventBase |
This class provides support for handling / dispatching events and is
the base class of the three main client protocols (DispatchClient,
NotificationClient, SwitchboardClient) |
MSNMessage |
I am the class used to represent an 'instant' message. |
NotificationClient |
This class provides support for clients connecting to the notification
server. |
NotificationFactory |
Factory for the NotificationClient protocol. |
PassportLogin |
This class is used internally to obtain a login ticket from a passport
HTTPS server -- it should not be used directly. |
PassportNexus |
Used to obtain the URL of a valid passport login HTTPS server. |
SwitchboardClient |
This class provides support for clients connecting to a switchboard
server. |
Exceptions |
MSNProtocolError |
This Exception is basically used for debugging purposes, as the
official MSN server should never send anything _wrong_ and nobody in
their right mind would run their own MSN server. |
