Я получаю исключение как на стороне клиента, так и на стороне сервера, когда я запускаю первый пример на http://buildbot.twistedmatrix.com/builds/sphinx-html/291-15849/projects/web/howto/xmlrpc.html. Код сервера, который я использовал, приведен ниже:
from twisted.web import xmlrpc, server
class Example(xmlrpc.XMLRPC):
"""An example object to be published."""
def xmlrpc_echo(self, x):
"""
Return all passed args.
"""
return x
def xmlrpc_add(self, a, b):
"""
Return sum of arguments.
"""
return a + b
def xmlrpc_fault(self):
"""
Raise a Fault indicating that the procedure should not be used.
"""
raise xmlrpc.Fault(123, "The fault procedure is faulty.")
if __name__ == '__main__':
from twisted.internet import reactor
r = Example()
reactor.listenTCP(7080, server.Site(r))
reactor.run()
На стороне клиента ниже:
import xmlrpclib
s = xmlrpclib.Server('http://localhost:7080/')
print s.echo('Hello world')
Исключение на стороне сервера:
