使用python suds连接到Dynamics CRM

使用python suds连接到Dynamics CRM

nim*_*m4n 5 python suds dynamics-crm-2011

我想使用microsoft CRM webservice,我试过这段代码:

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)

我收到此错误:

最后我连接到 crm Web 服务。但是当我执行请求时，出现“400，u'Bad Request'”错误！

我的代码是：

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)
