I rewrite a custom authenticator based on
GenericOauthenticator in order to use different
client_id based on the next_url from the login phase.
The login URL is: https://<dummy.com>/hub/login?next=%2Fhub%2Fuser-redirect%2Fapps%2Fapps%2Fquantum-espresso%2Fqe.ipynb
I want read the parameters of next URL and pass it to
authenticate method of my Authenticator class. Is that possible to do this? Thanks for advance if you know how to do this.
