Hello community,
maybe one of you can help me out with a question regarding the
transfer of objects betwen client an server:
I have three files:
####### ClassA.py #######
class ClassA:
def setA(self, newA):
self.a = newA
def getA(self):
return self.a
####### client.py #######
import xmlrpclib
from ClassA import *
a = ClassA()
a.setA(4711)
server = xmlrpclib.ServerProxy("http://localhost:8888")
print server.getA(a) # <= here I would like to hand over an
object
####### server.py #######
import SimpleXMLRPCServer
from ClassA import *
class Handler:
def getA(self, aClass):
return aClass.getA() # <- XMLRPC only transports simple types and
dictionaries, but no objects
handler_object = Handler()
server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost" , 8888))
server.register_instance(handler_object)
print "Listening on port 8888"
server.serve_forever()
The problem is, that though I hand a ClassA object to the XMLRPC
server, the server only receives a dictionary (only transfering simple
objects is a XMLRPC feature: http://docs.python.org/lib/module-xmlrpclib.html)
Since XMLRPC has limited features: Is there any other server/client
technique to transfer objects (not strings, or dictionaries, but self
defined object types) ?
Regards
Bernd
