Python 2中的TFS Rest Api授权问题

Question

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()

1. 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

2. 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.
