A simple library that implements a pingback client. The library supports version 1.0 of the pingback library, based upon the specification published at http://www.hixie.ch/specs/pingback/pingback.
Pingback can now be implemented by using one of the following functions:
def autoPingback(sourceURI, reST = None, HTML = None): """Scans the input text, which can be in either reStructuredText or HTML format, pings every linked website for auto-discovery-capable pingback servers, and does an appropriate pingback.""" def pingback(sourceURI, targetURI): """Attempts to notify the server of targetURI that sourceURI refers to it.""" ...
Implementing a pingback server is beyond the scope of this library simply because of the very application-specific nature of a server. However, it is also trivially easy to create a pingback server by using Python's SimpleXMLRPCServer module. The following simple framework could be used by a CGI script to implement a pingback server:
def pingback(sourceURI, targetURI): '''Do something interesting!''' return "arbitrary string return value." import SimpleXMLRPCServer handler = SimpleXMLRPCServer.CGIXMLRPCRequestHandler() handler.register_function(pingback, "pingback.ping") handler.handle_request()
It would still be necessary to provide an X-Pingback HTTP header which pointed at the given CGI script.
