When I try to connect to an MS
CRM web service using suds/python-ntlm, I am getting a timeout
on requests. However, the code that I'm trying to replace -- which calls out to the cURL command line app to do the same call -- succeeds.
Clearly something is different in the way that cURL is sending the command data, but I'll be damned if I know what the difference is. Below are the full details of the various calls. Anyone got any tips?
Here's the code that is making the request, followed by the output. The cURL command code is below that, and its response follows. Hosts, users, and passwords have been changed to protect the innocent, of course.
wsdl_url = 'https://client.service.host/MSCrmServices/2007/MetadataService.asmx?WSDL'
username = r'domain\user.name'
password = 'userpass'
from suds.transport.https import WindowsHttpAuthenticated
from suds.client import Client
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)
ntlmTransport = WindowsHttpAuthenticated(username=username, password=password)
metadata_client = Client(wsdl_url, transport=ntlmTransport)
request = metadata_client.factory.create('RetrieveAttributeRequest')
request.MetadataId = '00000000-0000-0000-0000-000000000000'
request.EntityLogicalName = 'opportunity'
request.LogicalName = 'new_typeofcontact'
request.RetrieveAsIfPublished = 'false'
attr = metadata_client.service.Execute(request)
print attr
Here's the output:
