Configuration Additions (`config.py`) + +Add to `Settings` class: +```python +# OAuth2 Settings +oauth2_issuer: str = "http://localhost:8000" # Used for discovery +oauth2_access_token_expire_minutes: int = 30 +oauth2_refresh_token_expire_days: int = 7 +oauth2_authorization_code_expire_minutes: int = 10 +oauth2_supported_grant_types: List[str] = ["authorization_code", "client_credentials", "refresh_token"] +oauth2_supported_scopes: List[str] = ["openid", "profile", "email", "api:read", "api:write"] +oauth2_pkce_required: bool = False # Future enhancement +``` + +### 7. Updates to `app.py` + +Add after admin router inclusion: +```python +from oauth2.controller import router as oauth_router + +# Include OAuth2 router +app.include_router(oauth_router) +``` + +Ensure OAuth2 router is added **before** the dynamic route registration? Order doesn't matter because routes are matched sequentially; OAuth2 routes have specific prefixes. + +### 8. Authorization Code Storage + +Create `oauth2/auth_code_store.py` with a simple in‑memory store (dictionary) mapping code β†’ dict (client_id, redirect_uri, scopes, user_id, expires_at).

Authorization Code Store + +Create `oauth2/auth_code_store.py` with an in‑memory dictionary protected by `asyncio.Lock`. Store authorization codes with expiration (datetime). Provide methods: + +- `store_code(code: str, data: dict)` +- `get_code(code: str) -> Optional[dict]` +- `delete_code(code: str)` + +## 6. Template Requirements + +All admin templates extend `base.html` and use Bootstrap 5 styling. + +- **oauth_clients.html**: Table with columns: Client ID, Name, Grant Types, Redirect URIs, Active, Actions. +- **oauth_client_form.html**: Form fields: client_id, client_secret (plaintext), name, redirect_uris (newline‑separated), grant_types (checkboxes), scopes (newline‑separated), is_active (checkbox). +- **oauth_tokens.html**: Table with columns: Access Token (truncated), Client, User, Scopes, Expires, Active, Revoke button. +- **authorize_consent.html**: Simple page showing client name, requested scopes, Allow/Deny buttons. + +## 7. Integration with Existing Code + +- Use existing `OAuthService`, `TokenService`, `ClientService`, `ScopeService`. +- Use `OAuthClientRepository`, `OAuthTokenRepository`, `OAuthUserRepository`. +- Update `app.py` to include OAuth2 router after admin router. + +## 8. Security Considerations + +- Validate redirect_uri exactly (including query parameters). +- Hash client secrets with bcrypt (already implemented). +- Implement token revocation by deletion from database. +- Use `state` parameter for CSRF protection in authorization flow. +- Log all authentication failures. + +## 9. Implementation Steps for @coder + +1. **Create authorization code store** (`oauth2/auth_code_store.py`). +2. **Implement OAuth2 controller** (`oauth2/controller.py`) with all endpoints. +3. **Extend admin controller** (`controllers/admin_controller.py`) with OAuth2 management routes. +4. **Create HTML templates** in `templates/admin/` and `templates/oauth/`. +5. **Update configuration** (`config.py`) with OAuth2 settings. +6. **Update app** (`app.py`) to include OAuth2 router. +7. **Test** with curl/Postman and verify admin pages. + +## 10. Example Code Snippets + +### OAuth2 Controller Example +```python +# oauth2/controller.py +@router.post("/token") +async def token_endpoint( + grant_type: str = Form(...), + client_id: Optional[str] = Form(None), + client_secret: Optional[str] = Form(None), + code: Optional[str] = Form(None), + redirect_uri: Optional[str] = Form(None), + refresh_token: Optional[str] = Form(None), + scope: Optional[str] = Form(None), + db: AsyncSession = Depends(get_db), +): + oauth_service = OAuthService(db) + if grant_type == "authorization_code": + # validate code, redirect_uri + pass + # ... +``` + +### Admin Controller Example +```python +# controllers/admin_controller.py +@router.get("/oauth/clients", response_class=HTMLResponse) +async def list_oauth_clients( + request: Request, + page: int = 1, + db: AsyncSession = Depends(get_db), +): + repo = OAuthClientRepository(db) + clients = await repo.get_all(skip=(page-1)*PAGE_SIZE, limit=PAGE_SIZE) + # render template +``` + +## 11. Next Steps (Phase 6.5) +- Update `PROJECT_PLAN.md` with completed items. +- Write integration tests for OAuth2 flows. +- Consider adding PKCE support (optional). + +--- +**Approval Required**: Please review this specification before implementation begins. Any changes should be documented in `PROJECT_PLAN.md`. \ No newline at end of file diff --git a/app.py b/app.py new file mode 100644 index 0000000..53ae31b --- /dev/null +++ b/app.py @@ -0,0 +1,98 @@ +import logging +from contextlib import asynccontextmanager + +from fastapi import FastAPI, Request, status +from starlette.middleware.sessions import SessionMiddleware +from fastapi.responses import RedirectResponse +from starlette.staticfiles import StaticFiles + +from config import settings +from database import init_db, AsyncSessionLocal +from repositories.endpoint_repository import EndpointRepository +from services.route_service import RouteManager +from middleware.auth_middleware import AuthMiddleware +from controllers.admin_controller import router as admin_router +from oauth2 import oauth_router + + +logging.basicConfig( + level=logging.DEBUG if settings.debug else logging.INFO, + format="%(asctime)s - %(name)s - %(levelname)s - %(message)s", +) +logger = logging.getLogger(__name__) + + +@asynccontextmanager +async def lifespan(app: FastAPI): + """ + Lifespan context manager for startup and shutdown events. + """ + #

Client Credentials
+

Client ID and secret will be generated automatically upon creation. The secret will be shown only once – store it securely.

+ +
Redirect URIs
+

Must be absolute URIs with scheme http:// or https://. The redirect URI used in authorization requests must match exactly.

+ +
Grant Types
+
    +
  • authorization_code: For web server applications.
    • +
  • client_credentials: For machine‑to‑machine authentication.
    • +
  • password: For trusted first‑party clients (discouraged).
    • +
  • refresh_token: Allows obtaining new access tokens.
    • +
+ +
Security
+

Client secrets are hashed using bcrypt before storage. Never expose secrets in logs or client‑side code.
