11.21.1 SimpleXMLRPCServer Objects

The SimpleXMLRPCServer class provides two methods that an application can use to register functions that can be called via the XML-RPC protocol via the request handler.

register_function(function[, name])

Register a function that can respond to XML-RPC requests. The function must be callable with a single parameter which will be the return value of xmlrpclib.loads() when called with the payload of the request. If name is given, it will be the method name associated with function, otherwise function.__name__ will be used. name can be either a normal or Unicode string, and may contain characters not legal in Python identifiers, including the period character.

register_instance(instance)

Register an object which is used to expose method names which have not been registered using register_function(). If instance contains a _dispatch() method, it is called with the requested method name and the parameters from the request; the return value is returned to the client as the result. If instance does not have a _dispatch() method, it is searched for an attribute matching the name of the requested method; if the requested method name contains periods, each component of the method name is searched for individually, with the effect that a simple hierarchical search is performed. The value found from this search is then called with the parameters from the request, and the return value is passed back to the client.
