python-ntlm认证

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
