Tornado integration#

Install#

Install with pip or conda/mamba/micromamba

pip install py-oidc-auth[tornado]
conda install -c conda-forge py-oidc-auth-tornado

Minimal application#

import json

import tornado.ioloop
from py_oidc_auth import TornadoOIDCAuth, IDToken

auth = TornadoOIDCAuth(
    client_id="my-client",
    client_secret="secret",

Reusing database objects for token storage#

When using broker_mode=True the Identity Provider (IdP) tokens will be stored securely in a database. Instead of creating new database instances already existing database objects can be used to create a py_oidc_auth.broker.store.BrokerStore object. The following example uses an existing MongoDB connection:

 from pymongo import AsyncMongoClient
 from py_oidc_auth import MongoDBBrokerStore, TornadoOIDCAuth

 mongo_client = AsyncMongoClient("mongodb://myser:mypass@host")
 auth = TornadoOIDCAuth(
    client_id="my-client",
    client_secret="secret",
    discovery_url="https://idp.example.org/realms/demo/.well-known/openid-configuration",
    scopes="myscope profile email",
    audience="my-aud",
    broker_mode=True,
    broker_store_obj=MongoDBBrokerStore(db=mongo_client["my-app"]),
    broker_audience="myapp-api",
    trusted_issuers=["https://other-instance.example.org"],
)

Standard auth endpoints#

The router created by get_auth_routes() exposes these endpoints by default:

GET /auth/v2/login#

Starts the authorization code flow.

GET /auth/v2/callback#

Receives code and state from the provider.

POST /auth/v2/token#

Exchanges an authorization code or refresh token.

POST /auth/v2/device#

Starts the device authorization flow.

GET /auth/v2/logout#

Redirects to the provider logout endpoint.

GET /auth/v2/userinfo#

Calls the provider userinfo endpoint.

GET /api/auth/v2/.well-known/jwks.json#

Broker public key (broker mode only)

Notes#

The Tornado adapter exposes get_auth_routes which returns a list of (pattern, handler_class, init_kwargs) tuples. Combine them with your own handlers using standard list concatenation.
