OAuth2 (With Python)

[Udi]

I am trying to get an OAuth2 token with python. I am using the foloowing code:

payload = {
    "grant_type": "authorization_code",
    "client_id": CLIENT_ID,
    "client_secret": CLIENT_SECRET,
    "code": code,
    "redirect_uri": redirect_uri,
}
r = requests.post("https://www.openstreetmap.org/oauth2/token", data=payload)

(Where code is returned from the first auth part.)

Instead of the token I keep getting HTTP 401 responses with:

{"error":"invalid_client","error_description":"Client authentication failed due to unknown client, no client authentication included, or unsupported authentication method."}

Any help would be appreciated!

Thank you!

have you followed OAuth - OpenStreetMap Wiki ?

Yes. I did. I get a url with code+state params

1. Register an OAuth2 application in OSM with redirect uri ‘http://127.0.0.1:8000’ and store the application id and secret
2. run this code

from requests_oauthlib import OAuth2Session

# Set up your OAuth2 credentials - localhost
client_id = <client-id>
client_secret = <client-secret>
redirect_uri = 'http://127.0.0.1:8000'
scope = ["read_gpx","write_gpx","write_api"]

oauth = OAuth2Session(client_id=client_id, redirect_uri=redirect_uri, scope=scope)

authorization_url, state = oauth.authorization_url('https://www.openstreetmap.org/oauth2/authorize')
print ("Please visit:\n" + authorization_url)
print ("\n\n")
authorization_response = "https://"+input('Enter the redirect url:\n')
token = oauth.fetch_token(
        'https://www.openstreetmap.org/oauth2/token',
        authorization_response=authorization_response,
        client_secret=client_secret)
print ("\n\n")
print ("Access token is:")
print(token["access_token"])

I unfortunately don’t know stuff about Python, haven’t used it in over a year, but have once implemented OpenStreetMap OAuth for @Zverik’s simple-revert:

coolultra1/simple-revert/blob/oauth/simple_revert/osm_auth.py

As this, at least for the time I implemented it, worked, I’d try starting from there.
