Unable to access token using gis._con.token

DCWORK_GIS — Tue, 28 Nov 2023 01:31:18 GMT

Hello,
I'm hoping someone can help with this problem I ran into today. I can no longer access the authentication token using the Connect through Built-In account method, or the Connect through Pro method. Both of these methods worked for me up until today, and would return a token string accessed through gis._con.token. I can still get a token through OAuth, but I need to run scheduled scripts, unsupervised. Also, my org doesn't use Named User Authentication, so username/password isn't an option.

// This method still works, and returns a token:

gis = GIS('https:myGisPortal.maps.arcgis.com', client_id='myClientID')
print("Logged in as: " + gis.properties.user.username)
print('token='+str(gis._con.token))

Returns:
Logged in as: myUsername
token=sYzv_5rgSSiElv7...bzoR2oayAHTvuJG8

// But these methods don't work anymore, and do not return a token:

gis = GIS('pro')
print("Logged in as: " + gis.properties.user.username)
print('token='+str(gis._con.token))

Returns:
Logged in as: myUsername
token=None

gis = GIS('home')
print("Logged in as: " + gis.properties.user.username)
print('token='+str(gis._con.token))

Returns:
Logged in as: myUsername
token=None

To add context, I recently upgraded from AG Pro 2.9 to 3.2. Both authentication methods gis = GIS('home') & gis = GIS('pro') would allow access to the authentication token through token=gis._con.token in AG Pro 2.9, but this does not seem to be the case anymore in 3.x. 2 coworkers tested it in their 3.2 machines and it didn't work for them, and one tested it in 3.1.2, and it didn't work there either.

I have the same problem. To clarify, I am attempting to pass Active Directory credentials to GIS() to our enterprise portal.

gis = GIS('https://portalserver.domain.com/arcgis', 'Domain\\username', 'myPassword')

I know the authentication is succeeding because if I intentionally fudge the password the script fails.

Faced the same problem today with GIS("PRO"). The solution when using arcgis pro seems to be using the following code. I also tested GIS() with a URL to arcgis enterprise with a username and password and that also works.

import arcpy token = arcpy.GetSigninToken() if token is not None: print(token['token'])

Looks like this is still an issue in ArcGIS Pro 3.3./Python API 2.3.0. If arcpy is available, @Vincentvd's solution works, but we had a need to find a workaround when arcpy wasn't available.

I've had success using the authenticated session object for REST API and Sharing API calls to secured services instead of passing the token explicitly, like so (only tested on AGOL):

import json from arcgis.gis import GIS gis = GIS("pro") # Use the session from the GIS object session = gis._con._session # Example secured URL, doesn't have to be admin, just an example update_definition_url = "https://services8.arcgis.com/XXXXXXXXXXXXXXXX/arcgis/rest/admin/services/XXXXXXXXXXX/FeatureServer/updateDefinition" # Define some parameters for the update; again, just an example update_def_params = { 'updateDefinition': json.dumps({ "capabilities": "Query,Editing,Create,Update,Delete,Sync" }), 'async': 'false', 'f': 'json' } response = session.post(update_definition_url, data=update_def_params, timeout=10) result = response.json() print(result)

This apparently provides a subclass of a Requests session, so you can use it in place of requests; e.g., session.get, session.post, etc. Your mileage may vary, but this solved the problem for me in a workflow where arcpy wasn't an option.

I haven't tested yet but this looks promising. The ArcPy solution is good too, but if you want to use arcPy in a Notebook on AGOL you have to pay extra. Thanks!
