Unable to fetch OAuth2.0 Token from Azure-DevOps , using Python

I am trying to use OAuth2 to access the Azure DevopsAPI, to query work-items.
But I am unable to get the access tokene.
I am using Python and Flask. My approach is based on these resources:
Microsoft documentation , there currently Step 3 is relevant
OAuth Tutorial, which worked fine for Github, but is not working for Azure.
Relevant libraries:
from requests_oauthlib import OAuth2Session
from flask import Flask, request, redirect, session, url_for
Parameters:
client_id = "..."
client_secret = "..."
authorization_base_url = "https://app.vssps.visualstudio.com/oauth2/authorize"
token_url = "https://app.vssps.visualstudio.com/oauth2/token"
callback_url = "..."
Step 1: User Authorization. (works fine)
#app.route("/")
def demo():
azure = OAuth2Session(client_id)
authorization_url, state = azure.authorization_url(authorization_base_url)
session['oauth_state'] = state
authorization_url += "&scope=" + authorized_scopes + "&redirect_uri=" + callback_url
print(authorization_url)
return redirect(authorization_url)
Step 2: Retrieving an access token (generates an error)
#app.route("/callback", methods=["GET"])
def callback():
fetch_body = "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer" \
"&client_assertion=" + client_secret + \
"&grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer" \
"&assertion=" + request.args["code"] + \
"&redirect_uri=" + callback_url
azure = OAuth2Session(client_id, state=session['oauth_state'])
token = azure.fetch_token(token_url=token_url, client_secret=client_secret,
body=fetch_body,
authorization_response=request.url)
azure.request()
session['oauth_token'] = token
return redirect(url_for('.profile'))
The application-registration and adhoc-SSL-certification are working fine (using it just temporary).
When I use the client_assertion in Postman, I get a correct response from Azure:
But when I execute the code, this error is thrown:
oauthlib.oauth2.rfc6749.errors.MissingTokenError: (missing_token) Missing access token parameter.
Which only lets me know, that no token was received.
There is one issue in the generated request body, where the grant_type is added twice:
grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer
grant_type=authorization_code
The first value is expected by Azure, but the second one is generated automatically by the library.
Now when I specify the grant_type in the fetch_token call, like this:
token = azure.fetch_token(token_url=token_url, client_secret=client_secret,
body=fetch_body, grant_type="urn:ietf:params:oauth:grant-type:jwt-bearer",
authorization_response=request.url)
I get this error
TypeError: prepare_token_request() got multiple values for argument 'grant_type'
And the actual request to Azure is not even sent.
I see in the web_application.py that is used by oauth2_session.py, that grant_type ='authorization_code' is set fixed, so I guess this library is generally incompatible with Azure.
Is that the case?
If so, what would be the simplest way to connect to Azure-OAuth with Python (Flask)?
I would be very grateful for any advice and help that point me in the right direction.

I just found the azure.devops library that solves my problem.

eBay Marketplace Account Deletion/Closure Notifications

I am trying to start an eBay API in Python and I can't find a single answer as to how to get an API key with eBay's new requirements of "Account Deletion/Closure Notifications." Here's the link: https://developer.ebay.com/marketplace-account-deletion
Specifically, I am told that "Your Keyset is currently disabled" because I have not completed whatever process is needed for this marketplace account deletion/closure notification.
The problems?
I have no idea if I need this.
I have no idea how to actually do this.
Re: 1. It looks like this is for anyone who stores user data. I don’t think that’s me intentionally because I really just want to get sold data and current listings, but is it actually me?
Re: 2. I don’t understand how to validate it and send back the proper responses. I’ve gotten quite good at python but I’m lost here.
eBay forums are completely useless and I see no one with an answer to this. Any help is greatly appreciated.

Re: 1. Same. Here's my interpretation: In order to use their APIs, you need to provide (and configure) your own API, so they can communicate with you —programatically— and tell you what users have asked to have their accounts/data deleted.
Re: 2. To handle their GET and POST requests, I guess you'll need to configure a website's URL as an API endpoint. In Django, I might use something like this (untested) code:
import hashlib
import json
from django.http import (
HttpResponse,
JsonResponse,
HttpResponseBadRequest
)
def your_api_endpoint(request):
"""
API Endpoint to handle the verification's challenge code and
receive eBay's Marketplace Account Deletion/Closure Notifications.
"""
# STEP 1: Handle verification's challenge code
challengeCode = request.GET.get('challenge_code')
if challengeCode is not None:
# Token needs to be 32-80 characters long
verificationToken = "your-token-012345678901234567890123456789"
# URL needs to use HTTPS protocol
endpoint_url = "https://your-domain.com/your-endpoint"
# Hash elements need to be ordered as follows
m = hashlib.sha256((challengeCode+verificationToken+endpoint_url).encode('utf-8'))
# JSON field needs to be called challengeResponse
return JsonResponse({"challengeResponse": m.hexdigest()}, status=200)
# STEP 2: Handle account deletion/closure notification
elif request.method == 'POST':
notification_details = json.loads(request.body)
# Verify notification is actually from eBay
# ...
# Delete/close account
# ...
# Acknowledge notification reception
return HttpResponse(status=200)
else:
return HttpResponseBadRequest()
If you find the answer to question number one, please do let me know.

Re: 1. You need to comply with eBay's Marketplace Account Deletion/Closure Notification workflow if you are storing user data into your own database. For example, using eBay's Buy APIs, you may get access to what users are selling on eBay (for ex. an eBay feed of products). If those eBay sellers decide they want to remove all of their personal data from eBay's database, eBay is requesting you remove their data from your database as well. If you are NOT storing any eBay user data into your database, you do not need to comply. Here is where you can find more info: https://partnerhelp.ebay.com/helpcenter/s/article/Complying-with-the-eBay-Marketplace-Account-Deletion-Closure-Notification-workflow?language=en_US
Re: 2. To be honest I've spent days trying to figure this out in Python (Django), but I have a solution now and am happy to share it with whoever else comes across this issue. Here's my solution:

I've been trying #José Matías Arévalo code. It works except "STEP 2" branch - Django returns 403 error. This is because of by default Django uses CSRF middleware (Cross Site Request Forgery protection). To avoid 403 error we need to marks a view as being exempt from the protection as described here https://docs.djangoproject.com/en/dev/ref/csrf/#utilities so add couple strings in code:
from django.views.decorators.csrf import csrf_exempt
#csrf_exempt
def your_api_endpoint(request):
And in my case I use url "https://your-domain.com/your-endpoint/" with slash symbol "/" at the end of url. Without this slash eBay doesn't confirm subscription.

I am using Flask and this is the code I have used:
from flask import Flask, request
import hashlib
# Create a random verification token, it needs to be 32-80 characters long
verification_token = 'a94cbd68e463cb9780e2008b1f61986110a5fd0ff8b99c9cba15f1f802ad65f9'
endpoint_url = 'https://dev.example.com'
app = Flask(__name__)
# There will be errors if you just use '/' as the route as it will redirect eBays request
# eBay will send a request to https://dev.example.com?challenge_code=123
# The request will get redirected by Flask to https://dev.example.com/?challenge_code=123 which eBay will not accept
endpoint = endpoint_url + '/test'
# The Content-Type header will be added automatically by Flask as 'application/json'
#app.route('/test')
def test():
code = request.args.get('challenge_code')
print('Requests argument:', code)
code = code + token + endpoint
code = code.encode('utf-8')
code = hashlib.sha256(code)

Update/Add labels to Google Kubernetes Engine Cluster Workloads through Python API

Has anyone tried to add or update the Clusters from Google Kubernetes Engine through Python API?
I managed to do this for Compute instances, but the guide for Kubernetes Engine says its deprecated:
https://cloud.google.com/kubernetes-engine/docs/reference/rest/v1/projects.zones.clusters.nodePools/update
Tried it and it fails saying it does not find "labels":
googleapiclient.errors.HttpError: <HttpError 400 when requesting
https://container.googleapis.com/v1/projects/testingproject/zones/us-east1/clusters/testing-cluster/resourceLabels?alt=json
returned "Invalid JSON payload received. Unknown name "labels": Cannot
find field.". Details: "[{'#type':
'type.googleapis.com/google.rpc.BadRequest', 'fieldViolations':
[{'description': 'Invalid JSON payload received. Unknown name
"labels": Cannot find field.'}]}]">
My code is this:
credentials = GoogleCredentials.get_application_default()
service = discovery.build('container', 'v1', credentials=credentials)
# Deprecated. The Google Developers Console [project ID or project
# number](https://developers.google.com/console/help/new/#projectnumber).

I want to update the Workload named 'matei-testing-2000-gke-ops' inside the cluster 'testing-cluster'.
Any ideas?
Thank you
Update: It does not find the labels because the name is resourceLabels. But I get the following error after:
googleapiclient.errors.HttpError: <HttpError 400 when requesting
https://container.googleapis.com/v1/projects//zones//clusters//resourceLabels?alt=json

I've not now tried this.
But IIUC, you'll need to:
ditch (or use defaults) for e.g. project_id, zone and cluster_id parameters of resourceLabels
add name to your body and it should be of the form: projects/*/locations/*/clusters/*
i.e.

from googleapiclient import discovery
from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials.get_application_default()
service = discovery.build('container', 'v1', credentials=credentials)
PROJECT = os.getenv("PROJECT")
LOCATION = os.getenv("ZONE")
CLUSTER = os.getenv("CLUSTER")
NAME = "projects/{project}/locations/{location}/clusters/{cluster}".format(
project=project_id,
location=zone,
cluster=cluster_id)
# To update `resourceLabels` you must first fingerprint them
# To get the current `labelFingerprint`, you must `get` the cluster
body = {
'name': NAME,
}
request = service.projects().zones().clusters().get(
projectId=project_id,
zone=zone,
clusterId=cluster_id)
response = request.execute()
labelFingerprint = response["labelFingerprint"]
if "resourceLabels" in response:
print("Existing labels")
resourceLabels = response["resourceLabels"]
else:
print("No labels")
resourceLabels = {}
# Add|update a label
resourceLabels["dog"] = "freddie"
# Construct `resourceLabels` request
body = {
'name': NAME,
'resourceLabels': resourceLabels,
'labelFingerprint': labelFingerprint,
}
request = service.projects().zones().clusters().resourceLabels(
projectId=project_id,
zone=zone,
clusterId=cluster_id,
body=body)
# Do something with the `response`
response = request.execute()
clusters.get
`clusters#CLuster
And

Youtube API commentThreads.update return 400 error when replying to topLevelComment

Reporting a possible bug on Youtube Api commentThreads.update
Name of API affected: CommentThreads: update
Issue summary: CommentThreads: update When calling this api to update the topLevelComment returned by CommentThreads.list, I got a 400 error. I was using this API in an internal tool to allow me respond to comments. It was working fine for the last months... and in the last days (~2016-11-07) with no changes on any code on my side, the API started to return a 400 error. I have all my internal comment systems halted right now as I could not figure out how to fix this. Every thing I tried and tested brings me to the 400 error and the message below.
"While this can be a transient error, it usually indicates that the requests input is invalid."
Even using the API console, I got the same errror!
My bet? This is a transient error that I hope Google can fix.
Steps to reproduce issue:
Retrieve "heldForReview" threads using CommentThreads.list
Try to update the returned topLevelComment changing ["topLevelComment"]["snippet"]["textOriginal"] = "some text". Optionally, change the "moderationStatus" to "published". The error is the same.
This behaviour can be easily spotted using the Python API samples, specifically the file comment_threads.py from https://github.com/youtube/api-samples/blob/master/python/comment_threads.py
Expected output: The top level comment from Thread should become visible (after setting the moderationStatus to published) and have the "some text" as the first child comment as its answer.
Actual results:
{
"error": {
"errors": [
{
"domain": "youtube.commentThread",
"reason": "processingFailure",
"message": "The API server failed to successfully process the request. While this can be a transient error, it usually indicates that the requests input is invalid. Check the structure of the \u003ccode\u003ecommentThread\u003c/code\u003e resource in the request body to ensure that it is valid.",
"locationType": "other",

learning python with yelp api

I'm just beginning to learn python/django. I've been teaching myself PHP and now I would like to learn python. I'm having issues integrating yelp's API. I'm getting errors:
Values instance has no attribute 'q'
I have this code:
def search(request):
parser = optparse.OptionParser()
parser.add_option('-c', '--consumer_key', dest='my_consumer_key_goes_here', help='OAuth consumer key (REQUIRED)')
parser.add_option('-s', '--consumer_secret', dest='my_consumer_secret_goes_here', help='OAuth consumer secret (REQUIRED)')
parser.add_option('-t', '--token', dest='my_token_goes_here', help='OAuth token (REQUIRED)')
parser.add_option('-e', '--token_secret', dest='my_token_secret_goes_here', help='OAuth token secret (REQUIRED)')
parser.add_option('-a', '--host', dest='host', help='Host', default='api.yelp.com')
options, args = parser.parse_args()
# search stuff?
if 'q' in request.GET and request.GET['q']:
q = request.GET['q']
parser.add_option('-q', '--term', dest=q, help='Search term')
url_params = {}
if options.q:
url_params['term'] = options.q
# Sign the URL
consumer = oauth2.Consumer(consumer_key, consumer_secret)
oauth_request = oauth2.Request('GET', url, {})
oauth_request.update({'oauth_nonce': oauth2.generate_nonce(),
'oauth_timestamp': oauth2.generate_timestamp(),
'oauth_token': token,
'oauth_consumer_key': consumer_key})
token = oauth2.Token(token, token_secret)
oauth_request.sign_request(oauth2.SignatureMethod_HMAC_SHA1(), consumer, token)
signed_url = oauth_request.to_url()
else:
message = 'You submitted an empty form.'
#return HttpResponse(message)
print 'Signed URL: %s\n' % (signed_url,)
# Connect
try:
conn = urllib2.urlopen(signed_url, None)
try:
response = json.loads(conn.read())
finally:
conn.close()
except urllib2.HTTPError, error:
response = json.loads(error.read())
return response
response = request(options.host, '/v2/search', url_params, options.consumer_key, options.consumer_secret, options.token, options.token_secret)
print json.dumps(response, sort_keys=True, indent=2)
Now as I'm still new to this whole python language, I wonder if I'm also adding the API consumer_key, secret, etc... in the right places? Do I even have this code set correctly? Most of it was from the original yelp api script. I guess the issue lies in the if options.q: area... not sure if I'm doing this correctly?
Thanks

I would say that calling parser.parse_args() before you declared your q option is probably your immediate problem.
But unless I am missing something about what you are trying to do, Django settings [1] are what you need to use for those first 5 options (don't use optparse at all). And then I don't know what you are trying to do with the rest of the function.
