fast-sso

fastsso is a Python package that facilitates the integration of Keycloak authentication in applications built with the FastAPI web framework.

Features 🎁

• Authentication with bearer JWT tokens.
• JWT token validation.
• Authorization based on roles, groups and the user's email verification state in Keycloak.
• Provides information about the validated user.
• Handy tools for checking roles, groups and other user attributes.

Usage 💡

Middleware

Use KeycloakFastSSOMiddleware to protect your API routes. You must first configure the connection to Keycloak with the appropriate parameters.

from fastapi import FastAPI
from keycloakfastsso.middleware import KeycloakFastSSOMiddleware

app = FastAPI()
app.add_middleware( KeycloakFastSSOMiddleware,
                    server_url="https://my-keycloak-url/auth/",
                    client_id="my-client-id",
                    realm_name="my-realm-name",
                    client_secret_key="my-client-secret-key")

Decorators

These decorators can be used to restrict access to routes based on user roles or groups.

from keycloakfastsso.decorators import require_role, require_group, require_scope, require_email_verified, require_active_user, require_token_type, require_resource_access, require_allowed_origin

@app.get("/require_role")
@require_role(["admin"])
def require_role_endpoint(): 
    return {"Hello": "World"}

@app.get("/require_group")
@require_group(["my_group"])
def require_group_endpoint(): 
    return {"Hello": "World"}

# other routes continue the same way 

Utilities

The utilities allow you to retrieve specific information about the currently authenticated user.

from keycloakfastsso.utils import KeycloakUtils

# In your route
@app.get("/whoami")
def who_am_i(request: Request):
    return {"user_id": KeycloakUtils.get_user_id(request)}
