Getting a 401 response while using Requests package

I am trying to access a server over my internal network under https://prodserver.de/info.
I have the code structure as below:
import requests
from requests.auth import *
username = 'User'
password = 'Hello#123'
resp = requests.get('https://prodserver.de/info/', auth=HTTPBasicAuth(username,password))
print(resp.status_code)
While trying to access this server via browser, it works perfectly fine.
What am I doing wrong?

By default, requests library verifies the SSL certificate for HTTPS requests. If the certificate is not verified, it will raise a SSLError. You check this by disabling the certificate verification by passing verify=False as an argument to the get method, if this is the issue.
import requests
from requests.auth import *
username = 'User'
password = 'Hello#123'
resp = requests.get('https://prodserver.de/info/', auth=HTTPBasicAuth(username,password), verify=False)
print(resp.status_code)

try using requests' generic auth, like this:
resp = requests.get('https://prodserver.de/info/', auth=(username,password)

What am I doing wrong?
I can not be sure without investigating your server, but I suggest checking if assumption (you have made) that server is using Basic authorization, there exist various Authentication schemes, it is also possible that your server use cookie-based solution, rather than headers-based one.
While trying to access this server via browser, it works perfectly
fine.
You might then use developer tools to see what is actually send inside and with request which does result in success.

Python SOAP client with Zeep - authentication

I am trying to use Zeep to implement a SOAP client, as it seems the only maintained library at the moment:
ZSI looked very good but its latest version on pypi dates 2006
suds seemed to be a popular alternative, but the master is unmaintained since 2011 and there are a lot of forks out there but none seems "official" and "recent" enough to be used in a large project.
So, trying to use Zeep, I am stuck with the authentication required by the server to access the WSDL.
Such operation was quite easy with ZSI:
from ZSI.client import Binding
from ZSI.auth import AUTH
b = Binding(url='http://mysite.dom/services/MyWebServices?WSDL')
b.SetAuth(AUTH.httpbasic, 'userid', 'password')
and I can find something similar in __main__.py of Zeep:
from six.moves.urllib.parse import urlparse
from zeep.cache import InMemoryCache, SqliteCache
from zeep.client import Client
from zeep.transports import Transport
cache = SqliteCache() if args.cache else InMemoryCache()
transport_kwargs = {'cache': cache}
result = urlparse(args.wsdl_file)
if result.username or result.password:
transport_kwargs['http_auth'] = (result.username, result.password)
transport = Transport(**transport_kwargs)
client = Client(args.wsdl_file, transport=transport)
but that does not work in my case, I get an error:
Exception: HTTPConnectionPool(host='schemas.xmlsoap.org', port=80): Max retries exceeded with url: /soap/encoding/ (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f3dab9d30b8>: Failed to establish a new connection: [Errno 110] Connection timed out',))

Probably with the newer Version of zeep the older solution does not work anymore. Here is the new way:
from requests.auth import HTTPBasicAuth # or HTTPDigestAuth, or OAuth1, etc.
from requests import Session
from zeep import Client
from zeep.transports import Transport
session = Session()
session.auth = HTTPBasicAuth(user, password)
client = Client('http://my-endpoint.com/production.svc?wsdl',
transport=Transport(session=session))

For Basic Access Authentication you can use the HTTPBasicAuth class from the requests module, as explained on Zeep documentation http://docs.python-zeep.org/en/master/transport.html:
from requests.auth import HTTPBasicAuth # or HTTPDigestAuth, or OAuth1, etc.
from zeep import Client
from zeep.transports import Transport
client = Client('http://my-endpoint.com/production.svc?wsdl',
transport=Transport(http_auth=HTTPBasicAuth(user, password)))

In my case the API I was working with required WS-Security (WSSE) rather than HTTP.
from zeep import Client
from zeep.wsse.username import UsernameToken
client = Client(<wsdl_url>, wsse=UsernameToken(<username>, <password>)

TFS Rest Api authorization issue in Python 2

I am trying to access TFS REST API in Python 2 but getting 401 Authorization Error. I am able to access API url from web-browser using same credentials. Also same credentials is working with .Net code. Tried with urllib2 library as guided in this solution. Any suggestion to access TFS api in Python2?
tfs.py
import requests
from requests.auth import HTTPDigestAuth
username = '<UserName>'
password = '<Password>'
tfsApi = 'https://{myserver}/tfs/collectionName/_apis/projects?api-version=2.0'
tfsResponse = requests.get(tfsApi, auth=(username, password))
if(tfsResponse.ok):
tfsResponse = tfsResponse.json()
print(tfsResponse)
else:
tfsResponse.raise_for_status()
Error:
Traceback (most recent call last):
File "D:\Scripts\tfs.py", line 13, in <module>
tfsResponse.raise_for_status()
File "C:\Python27\lib\site-packages\requests\models.py", line 862, in raise_fo
r_status
raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url: https://{myserver}/tfs/collectionName/_apis/projects?api-version=2.0
.Net Working code:
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", AppConfig.TFS_API_USER, AppConfig.TFS_API_PASS))));

TFS uses NTLM authentication protocol , Hence I have to update my code with HTTP NTLM authentication using the requests library.
Working code:
import requests
from requests_ntlm import HttpNtlmAuth
username = '<DOMAIN>\\<UserName>'
password = '<Password>'
tfsApi = 'https://{myserver}/tfs/collectionName/_apis/projects?api-version=2.0'
tfsResponse = requests.get(tfsApi,auth=HttpNtlmAuth(username,password))
if(tfsResponse.ok):
tfsResponse = tfsResponse.json()
print(tfsResponse)
else:
tfsResponse.raise_for_status()

It seems you want to get a list of team projects with REST API. The API should look like:
-
http://tfsserver:8080/tfs/CollectionName/_apis/projects?api-version=1.0
Make sure you have enabled Basic Auth for your TFS:
check your IIS to see whether the Basic authentication service role
is installed.
go to IIS Manager, select Team Foundation Server -- Authentication
and disable everything other than Basic Authentication. Then do the
same for the tfs node under Team Foundation Server.
restart your IIS.

Authenticate Windows Security with Request library

How can I authenticate in his Windows Security pop-up?
http://imgur.com/1FSkbUF
using requests and python?
from requests import session
with session() as c:
response = c.get('url', auth=('username', 'pass'),)
print(response.headers)
print(response.text)
but it does not work, it still prints error message source code

Ok, started working. It was just a internal server error. After several tries I had to be blocked for a while.

403 Forbidden Error for Python-Suds contacting Sharepoint

I'm using Python's SUDs lib to access Sharepoint web services.
I followed the standard doc from Suds's website.
For the past 2 days, no matter which service I access, the remote service always returns 403 Forbidden.
I'm using Suds 0.4 so it has built-in support for accessing Python NTLM.
Let me know if anyone has a clue about this.
from suds import transport
from suds import client
from suds.transport.https import WindowsHttpAuthenticated
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
ntlm = WindowsHttpAuthenticated(username='USER_ID', password='PASS')
c_lists = client.Client(url='https://SHAREPOINT_URL/_vti_bin/Lists.asmx?WSDL', transport=ntlm)
#c_lists = client.Client(url='https://SHAREPOINT_URL/_vti_bin/spsearch.asmx?WSDL')
#print c_lists
listsCollection = c_lists.service.GetListCollection()

Are you specifying the username as DOMAIN\USER_ID as indicated in examples for the python-ntlm library? (Also see this answer).
