在python中使用带有SimpleXMLRPCServer的**kwargs

from xmlrpc.server import SimpleXMLRPCServer
from xmlrpc.server import SimpleXMLRPCRequestHandler

from xmlrpclib import ServerProxy

class ArgsSimpleXMLRPCServer(SimpleXMLRPCServer):
    def _dispatch(self, methodname, args, result, **kw):
        if (args and isinstance(args, tuple) and 
            all(isinstance(arg, dict) for arg in args)):
            args = ArgsSimpleXMLRPCServer._unmarshal_kwargs(args)
            
        if kw:
            kw = ArgsSimpleXMLRPCServer._unmarshal_kwargs(kw)
            return self._dispatcher.dispatch(methodname, args, result, **kw)
            
        return self._dispatcher.dispatch(methodname, args, result)

    @staticmethod
    def _unmarshal_kwargs(kwargs):
        return {k: kwargs[k] for k in kwargs if k.startswith(("arg:", "kw:"))}

args_serlved = ArgsSimpleXMLRPCServer(('127.0.0.1', 0), allow_none=True)
args_serlved.register_introspection_functions()

# Register methods here. For example:
# args_serlved.register_function(add, '$add$')

args_serlved.register_function(add, ('arg:num1', 'arg:num2'))
args_serlved.serve_forever()
