Connect to Dynamics CRM with python suds

Question

I want to use microsoft CRM webservice, I tried this code:

wsdl_url = 'http://crm-test:5555/CRMDeveleopment/XRMServices/2011/Organization.svc?wsdl'
username = 'user'
password = 'pass'

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, cache=None)

and I get this error:

Traceback (most recent call last):
  File "crm.py", line 15, in <module>
    metadata_client = Client(wsdl_url, transport=ntlmTransport)
  File "/usr/lib/python2.7/site-packages/suds/client.py", line 112, in __init__

    raise TypeNotFound(self.ref)

Answer 1

It looks like you are configured to use SOAP 1.2. Can you try your request with Soap 1.1?

I say this because I'm looking at this walk through: http://msdn.microsoft.com/en-us/library/gg594434.aspx

The request mentioned there conforms to the earlier standard (as indicated by the mime type.)

As far as how to do this with the suds library: After reading through the documentation a bit, I was inclined to rip my own eyes out. (Just kidding, I'm just used to reading a different type of documentation I suppose.) I'm sure you're far more used to browsing it than I am, and would be able to figure it out very quickly: http://jortel.fedorapeople.org/suds/doc/

Answer 2

finnally I connect to crm web service.but I get ""400, u'Bad Request'"" error when I execute my reques!

my code is:

from suds import WebFault
from suds.client import *
from suds.transport.https import WindowsHttpAuthenticated
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.transport.http').setLevel(logging.DEBUG)
user = r'domain\username'
password = "pass"
url = "http://domain:5555/XRMServices/2011/Discovery.svc?wsdl"

ntlm = WindowsHttpAuthenticated(username = user, password = password)
client = Client(url, transport=ntlm)
print client
req = client.factory.create('ns3:RetrieveOrganizationsRequest')

accessTypes = client.factory.create('ns3:EndpointAccessType')
orgRel = client.factory.create('ns3:OrganizationRelease')

req.AccessType = accessTypes.Default
req.Release = orgRel.Current

headers = dict()
headers['Content-Type'] = 'application/soap+xml'
client.set_options(headers=headers)
resp = client.service.Execute(req)

the output of print client:

$ python newcrm.py
