flask_rp does not substitute {host} an {port} in configuration

[NubiaNetworks]

The configuration contains variables {host} and {port} to be substituted by the configured settings, however the names are procesdes ad verbatim by the oicrp services and generate invalid URLs. E.g:

2022-03-03 18:30:18,773 werkzeug INFO 127.0.0.1 - - [03/Mar/2022 18:30:18] "GET /authorization?redirect_uri=https%3A%2F%2F%7Bdomain%7D%3A%7Bport%7D%2Fauthz_cb%2Flocal&scope=openid+profile+email+address+phone&response_type=code&nonce=l88iJfCO4BZLDQkXYnUhgqFR&claims=%7B%22id_token%22%3A+%7B%22acr%22%3A+%7B%22value%22%3A+%22https%3A%2F%2Frefeds.org%2Fprofile%2Fmfa%22%7D%7D%7D&state=P9uak9aZ80hdofThXcjn7smnpPa5MDho&code_challenge=_yJm92poIHyUup6Wj3Gqcax9sJnyHSTZtb7l4PK380E&code_challenge_method=S256&client_id=fNHcM2Y5_NspBddQ8PDS5g HTTP/1.1" 400 -

I'd like to see the configuration file you're using.

[NubiaNetworks]

I'm using the default config.json files from oid-cop 'flask_op' and JWTConnect-Python-OidcRP's flask_rp

On the flask_op side I'm getting:

2022-03-04 08:49:30,205 oidcmsg.configure INFO request: {'application_type': 'web', 'response_types': ['code'], 'contacts': ['ops@example.com'], 'token_endpoint_auth_method': 'client_secret_basic', 'backchannel_logout_uri': 'https://{domain}:{port}/bc_logout/local', 'frontchannel_logout_uri': 'https://{domain}:{port}/fc_logout/local', 'redirect_uris': ['https://{domain}:{port}/authz_cb/local'], 'jwks_uri': 'https://127.0.0.1:8090/static/jwks.json', 'post_logout_redirect_uri': 'https://{domain}:{port}/session_logout/local', 'frontchannel_logout_session_required': True, 'grant_types': ['authorization_code']}

On the flask_rp side:

Which versions of OidcRP and oidc-op ?

[NubiaNetworks]

Both the git default branches.

I noticed that the actual substitution is supposed to happen in the Base class in the oidcmsg package which is version 1.6.0

Let me get back to you later today or tomorrow. A bit busy right now.

In #64 I created a test case to demonstrate the issue
It turned out to be a bug regarding an omitted 'uris' variable in RPConfigure.
Fix in the same pull request
