当我尝试使用 suds/python-ntlm 连接到 MS CRM Web 服务时，我的请求超时。但是，我试图替换的代码——调用 cURL 命令行应用程序来执行相同的调用——成功了。
显然，cURL 发送命令数据的方式有所不同，但如果我知道有什么区别，我会被诅咒的。以下是各种电话的完整详细信息。有人有任何提示吗？
这是发出请求的代码，然后是输出。cURL 命令代码在其下方，其响应如下。当然，主机、用户和密码已更改以保护无辜者。
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
这是输出：
