extract webid from session

[scenaristeur]

hi @Otto-AA
hi i'm trying to extract the web id from the session, like in js session.info.webid . Do you you an idea how to do that ?

Hi, how are you using this library?

If I remember correctly, client credentials are created for a specific web Id. So usually you should know the webId already, simply because you know for whom you created the client credentials.

Otherwise, it likely depends on the implementation details.

For the CSS version used in my integration tests, you can decode it and use the webid field:

import jwt # pyjwt or something similar

token_provider = DpopTokenProvider(
    issuer_url=issuer,
    client_id=credentials.client_id,
    client_secret=credentials.client_secret,
)
access_token = token_provider.get_uptodate_access_token()
data = jwt.api_jwt.decode_complete(access_token, options={'verify_signature': False})
webid = data['payload']['webid']
print(webid)

The access token looks similar to this: eyJhbGciOiJFUzI1NiIsInR5cCI6ImF0K2p3dCIsImtpZCI6ImRxbmRxN3JYNFhhNDQtYlZGZmRGbmw4VHZMbG1NenpVNWs4clFDMW5Ma1EifQ.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.0x0FkvZBDVBOHMCiNVhVWVDMKwd5UK98L5947Fgu5eGACyxOMNRC9NRkcPH4mW-uLq_VqNb_3tisshUwYr9Qlg (see https://jwt.io for decoding).
