Python web service

In my previous post, I have discussed using Perl (SoapLite) as client to consume a web service implemented using Java(Apache Axis). I am curious to find how it will work out for other lanuages such as Python and Ruby. Here is my try for Python.

The tool I use is ZSI which stands for Zolera SOAP Infrastructure. It provides a tool wsdl2py that can generate Python stub code from a wsdl file. Run the tool on the wsdl file described in my previous post, I get two Python modules: MessageRouter_services_types.py and MessageRouter_services.py. With the help of these two modules, consuming a web service is straight forward. Here is the code:

def sendTo(destination, payload):

 loc = MessageRoutingServiceLocator()
 kw = { 'tracefile' : sys.stdout }
 portType = loc.getMessageRouterPortType(**kw)

 dest = ns1.DestinationType_Def()
 dest._protocol = "http"
 dest._category = "post"
 dest._server = "127.0.0.1"
 dest._port = 80
 dest._target = "/router"

 msg = ns1.MessageBodyType_Def()
 msg._content = "payload"

 req = RouteRequestWrapper()
 req._destination = dest
 req._request = msg

 try:
  response = portType.RouteMessage(req)._response._content
  print "Response message is:\n %s" % response
 except Exception, e:
  response = repr(e)
  print "Failed: ", e
  raise e
