Problem :
I need to get a list of certificates of apps registered under Azure AD and renew the ones which are expiring.
I was able to get the apps related details through Microsoft Graph API > applications. But, the issue is the bearer token refreshes every time in 1 hr. Since I want this task to be automated, I need to create a fresh token always.
I got some reference of Azure SDK for identity-based authentication but the package function is returning a credential, not a token (bearer token) to be used inside the rest API header Authorization
Code:
from azure.identity import DefaultAzureCredential
default_credential = DefaultAzureCredential()
References:
Azure api or sdk to get list of app registrations and the certificates associated with them
Ok after a lot of debugging and surfing the internet, I was able to find the RestAPI way to get the bearer token.
data = {
"client_id":"add your client id",
"scope": "add scope ex: User.read Directory.read.All",
"grant_type": "password", [don't modify this one since you are providing the password]
"username": "your username",
"password": "your password",
"client_secret": "client secret"
}
headers = {
"Host": "login.microsoftonline.com",
"Content-Type": "application/x-www-form-urlencoded"
}
data = requests.post(f'https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/token', data=data, headers=headers)
You will receive a json consisting of access token and related details.
Do remember to provide the permissions in the azure portal> Azure AD > app registrations > your app > API permissions (grant consent)

I'm trying to create a python script which takes a (.csv with access tokens and a file) as input and uploads that file to multiple google drives whose access tokens are in that csv
but after sometime access tokens get expired and I have to get them again...just saw there's something called refresh and it refreshes access token
Is it possible to do this from python script, please explain.
Do refresh token expire?
import json
import requests
import pandas as pd
headers = {}
para = {
"name": "update",
}
files = {
'data': ('metadata', json.dumps(para), 'application/json; charset=UTF-8'),
'file': open("./update.txt", "rb")
}
tokens = pd.read_csv('tokens.csv')
for i in tokens.token:
headers={"Authorization": i}
r = requests.post(
"https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart",
headers=headers,
files=files
)
print(r.text)
In order to be able to get a new access_token programmatically using a refresh_token, you must have set access_type to offline when redirecting the user to Google's OAuth 2.0 server.
If you did that, you can get a new access_token if you do the following POST request to https://oauth2.googleapis.com/token:
POST /token HTTP/1.1
Host: oauth2.googleapis.com
Content-Type: application/x-www-form-urlencoded
client_id=your_client_id&
client_secret=your_client_secret&
refresh_token=refresh_token&
grant_type=refresh_token
The corresponding response would be something like:
{
"access_token": "1/fFAGRNJru1FTz70BzhT3Zg",
"expires_in": 3920,
"scope": "https://www.googleapis.com/auth/drive",
"token_type": "Bearer"
}
Note:
You can find code snippets for several languages in the reference I provide below, including Python, but considering you are not using the Python library, I think the HTTP/REST snippet I provided might be more useful in your situation.

I am deploying a Google Cloud Function from another Cloud Function with Python. See my code below:
import requests
import json
def make_func(request):
# Get the access token from the metadata server
metadata_server_token_url = 'http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token?scopes=https://www.googleapis.com/auth/cloud-platform'
token_request_headers = {'Metadata-Flavor': 'Google'}
token_response = requests.get(metadata_server_token_url, headers=token_request_headers)
token_response_decoded = token_response.content.decode("utf-8")
jwt = json.loads(token_response_decoded)['access_token']
# Use the api to create the function
response = requests.post('https://cloudfunctions.googleapis.com/v1/projects/myproject/locations/us-central1/functions',
json={"name":"projects/my-project/locations/us-central1/functions/funct","runtime":"python37","sourceArchiveUrl":"gs://bucket/main.zip","entryPoint":"hello_world","httpsTrigger": {} },
headers={'Accept': 'application/json',
'Content-Type': 'application/json',
'Authorization': 'Bearer {}'.format(jwt)} )
if response:
return 'Success! Function Created'
else:
return str(response.json())
However this function does not have "allow unauthenticated" on automatically. Thus, no requests from outside are allowed. How can I change my Python code to add this functionality when deploying the new function?
Thanks
You'll need to additionally give the allUsers member the Cloud Functions Invoker role:
from googleapiclient.discovery import build
service = build('cloudfunctions', 'v1')
project_id = ...
location_id = ...
function_id = ...
resource = f'projects/{project_id}/locations/{location_id}/functions/{function_id}'
set_iam_policy_request_body = {
'policy': {
"bindings": [
{
"role": "roles/cloudfunctions.invoker",
"members": ["allUsers"],
},
],
},
}
request = service.projects().locations().functions().setIamPolicy(
resource=resource,
body=set_iam_policy_request_body,
)
response = request.execute()
print(response)
This uses the google-api-python-client package.
In addition of Dustin answer, you have to know that the --allow-unauthenticated is for developer convenience. Under the hood it perform 2 things
Deploy your function in private mode
Add allUsers as member with Cloudfunction.invoker role
gcloud functions add-iam-policy-binding --member=allUsers --role=roles/cloudfunctions.invoker function-1
So, indeed, use the google-cloud-iam library for doing this.
In addition, your current code don't work because you use an access token to reach Cloud Function.
Indeed, you have an authorized error (401) -> You present an authorization header, but it's not authorize.
Without the header, you get a 403 error -> unauthenticated.
Anyway, you need to have a signed identity token. You have description and python code snippet here
I need to get the Instance List of my Google cloud project. So i tried this:
requests.get('https://compute.googleapis.com/compute/v1/projects/clouddeployment-265711/zones/europe-west3-a/instances)
How do i get authorization in python?.

Here is the full documentation on Server to Server authentication which also includes sample codes for every method supported.
In this GCP Github code, you can see multiple ways of authentication that you might choose from depending on your use-case.
For example with this code sample you can use a service account JSON key for authentication:
# [START auth_api_explicit]
def explicit(project):
from google.oauth2 import service_account
import googleapiclient.discovery
# Construct service account credentials using the service account key
# file.
credentials = service_account.Credentials.from_service_account_file(
'service_account.json')
# Explicitly pass the credentials to the client library.
storage_client = googleapiclient.discovery.build(
'storage', 'v1', credentials=credentials)
# Make an authenticated API request
buckets = storage_client.buckets().list(project=project).execute()
print(buckets)
# [END auth_api_explicit]
UPDATE:
If what you want is simply getting the Bearer token and storing it in a python variable to make a simple GET request:
import os
your_key = os.system('gcloud auth print-access-token')
so your_key will now have the Bearer token that you need to include in your request header
Otherwise, please read through this documentation which explains how to authenticate as an end-user.
I'm following the Get access without a user guide to write a Python script that will call Microsoft Graph.
This script will be scheduled from cron so it cannot get admin consent (therefore authorize using Client Credentials). I am able to successfully obtain a token using this call:
request_url = "https://login.microsoftonline.com/mytenant.onmicrosoft.com/oauth2/v2.0/token"
data = {
'Host' : 'login.microsoftonline.com',
'Content-Type' : 'application/x-www-form-urlencoded',
'client_id' : 'my-client-id-1234',
'scope' : 'https://graph.microsoft.com/.default',
'client_secret' : client_secret,
'grant_type' : 'client_credentials'
}
response = requests.post(url = request_url, data = data)
I then try to get a user listing with this call, using the valid token:
request_url = "https://graph.microsoft.com/v1.0/users"
headers = {
'Authorization' : 'Bearer ' + token,
'Host' : 'graph.microsoft.com'
}
response = requests.get(url = request_url, headers = headers)
The problem is that I get an Authorization_IdentityNotFound error:
<Response [401]>
{
"error": {
"code": "Authorization_IdentityNotFound",
"message": "The identity of the calling application could not be established.",
"innerError": {
"request-id": "2257f532-abc4-4465-b19f-f33541787e76",
"date": "2018-03-27T19:11:07"
}
}
}
These are the permissions I've selected:
Any idea how to fix this error?
For others running into this issue, I was also getting this error until found out the documentation omits a very important caveat:
For client credentials, if the app belongs to a work or school (organization) context then for https://login.microsoftonline.com/common/oauth2/token replace common with a tenantId or domain name
See
Authorization_IdentityNotFound on Microsoft Graph API request
First things first, you can go ahead an remove all those Delegated Permission scopes. If you're using the Client Credentials Grant, you will only be using Application Permission scopes.
Second, you need to execute the Admin Consent flow before you can use Client Credentials. This is done by having a Global Admin from the tenant authenticate and accept your scope request:
https://login.microsoftonline.com/common/adminconsent?client_id=[APPLICATION ID]&redirect_uri=[REDIRECT URI]
You can read more about Admin Consent here: v2 Endpoint and Admin Consent
I am trying to generate acces token from refresh token in django.
I am using Oauth2.
I am using oauth2 internal url for generating access token
i.e, 127.0.0.1:8000/o/token/
I am testing this in Rest Console.
My request is:
{ "client_id": "m5JjAzkqOCdH9MC4KV9EAjKuNhdMv2TyNDXgD6T7", "client_secret": "6C495R1BiA0lfXgm7lh0Zvqc6ugB7H6srlwSCLwyVNgoKqK7xGVQbB63Hj97E7fw3tWIgG7tnv9K5nwInaKPaaqSy4FLm8jaBdTPZ8YzlCJMkuiWNbIwc0ltFB7H9cgq",
"username": "lalit198910",
"grant_type": "refresh_token",
"token type" : "Bearer",
"refresh_token": "1svsHogo5tq6UxkiY55iMvMpWnGRsn" }
the error i am getting is:
"error": "unsupported_grant_type"
my content type is :
application/x-www-form-urlencoded
In Custom headers i have :
authorization type: bearer
value :3nKkSW9TEPjusuy2PzKhFxoTkFlqQC(Access token)
I have solved this problem,
I was using RAW BODY to pass my request data instead of using Request Paramters
