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.
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:
