如果我们在应用程序中访问用windows的域用户名，密码保护的TFS会出现401的错误，下述是解决办法。

Install python-ntlm from https://github.com/mullender/python-ntlm, then:

 

import urllib2

from ntlm import HTTPNtlmAuthHandler

import json

 

user = 'domain\\user'

password = 'password'

 

def GetSteps(url,user,pwd):

                passman = urllib2.HTTPPasswordMgrWithDefaultRealm()

                passman.add_password(None, url, user, pwd)

                # create the NTLM authentication handler

                auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)

 

                # create and install the opener

                opener = urllib2.build_opener(auth_NTLM)

                urllib2.install_opener(opener)

 

                res = urllib2.urlopen(url)

                # retrieve the result

                s = json.load(res)

               

                return s

 

if __name__ == '__main__':

                s = GetSteps("http://nlhfd-tfs300:8080/tfs/DefaultCollection/_apis/wit/workitems/128421",user,password)

                print s['fields']['Microsoft.VSTS.TCM.Steps']

以下是Github的描述----------------------------------------

python-ntlm

Python library that provides NTLM support, including an authentication handler for urllib2.

This library allows you to retrieve content from (usually corporate) servers protected with windows authentication (NTLM) using the python urllib2.

Python 3 Support

There is work going on to port the library to python 3, you can find it in the python30 directory. (at this time it seems to work as good as the python 2 library)

Usage

Simple example

import urllib2
from ntlm import HTTPNtlmAuthHandler

user = 'DOMAIN\User'
password = "Password"
url = "http://ntlmprotectedserver/securedfile.html"

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, user, password)
# create the NTLM authentication handler
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)

# create and install the opener
opener = urllib2.build_opener(auth_NTLM)
urllib2.install_opener(opener)

# retrieve the result
response = urllib2.urlopen(url)
print(response.read())

Extended Example

import urllib2
from urlparse import urlparse, urlunparse
from ntlm import HTTPNtlmAuthHandler

user = 'DOMAIN\User'
password = "Password"
url = "http://ntlmprotectedserver/securedfile.html"
# determine a base_uri for which the username and password can be used
parsed_url = urlparse(self.href)
base_uri = urlunparse((parsed_url[0],parsed_url[1],"","","",""))

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, base_uri, user, password)
# create the NTLM authentication handler
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)

# other authentication handlers
auth_basic = urllib2.HTTPBasicAuthHandler(passman)
auth_digest = urllib2.HTTPDigestAuthHandler(passman)

# disable proxies (if you want to stay within the corporate network)
proxy_handler = urllib2.ProxyHandler({})

# create and install the opener
opener = urllib2.build_opener(proxy_handler, auth_NTLM, auth_digest, auth_basic)
urllib2.install_opener(opener)

# retrieve the result    
response = urllib2.urlopen(url)
print(response.read())

Limitations

  • A request using the HTTPNtlmAuthHandler has no HTTP status handling, for example: redirects are not handled by the opener, you must check and handle the response yourself.

Resources

Inspired by

The NTLM Authorization Proxy Server can be used to make applications that do not support NTLM proxies use them anyway: "Opens up IIS Proxy Servers using NTLM to non-Microsoft browsers, etc"

In contrast the python-ntlm library is used to make it possible for python code to retrieve content from an NTLM protected server.
