Hi,
Is it possible to get in a notebook the email address (=Google user principal) of the currently logged in user when using the GoogleOAuthenticator?

It looks like the email address is included by default in

github.com

jupyterhub/oauthenticator/blob/af9b395b5e6ec6a0ef3731142b16e4f1899cadfd/oauthenticator/google.py#L135-L220


      
          async def authenticate(self, handler, data=None, google_groups=None):
              code = handler.get_argument("code")
              body = urllib.parse.urlencode(
                  dict(
                      code=code,
                      redirect_uri=self.get_callback_url(handler),
                      client_id=self.client_id,
                      client_secret=self.client_secret,
                      grant_type="authorization_code",
                  )
              )
          
          
    req = HTTPRequest(
                  self.token_url,
                  method="POST",
                  headers={"Content-Type": "application/x-www-form-urlencoded"},
                  body=body,
              )
              user = await self.fetch(req, "completing oauth")
              access_token = str(user['access_token'])

To access it you’ll need to turn on auth_state, and configure the spawner to pass the email to the spawned container as an environment variable (or some other method).

Oh thanks! I had only skimmed over that part of the documentation…

Let me see if I can wrap my head around it and understand how to make it work.
Seems relatively straight forward.
