# 🏗 Architectural Specification: OAuth2 Controllers (Phase 6.4)
## 🎯 Design Philosophy
"We are implementing a **Strategy pattern** for OAuth2 grant types (already established in OAuthService) and **Repository-Service-Controller** pattern for clean separation of concerns. The OAuth2 endpoints follow RFC 6749, 7662, 7009, and OpenID Connect Core 1.0 (userinfo). Admin management routes extend the existing admin interface with consistent session-based authentication."
### 🔍 Discovery & Analysis
**Current State**:
- OAuth2 models, repositories, schemas, and services are already implemented.
- RouteManager already validates OAuth2 tokens for endpoints with `requires_oauth=True`.
- Admin interface uses session middleware (`AuthMiddleware`) protecting `/admin/*` routes.
- Existing pattern: controllers define routers, use dependencies for DB sessions, and Jinja2 templates for HTML responses.
**Dependencies**:
- `oauth2/services.py`: `OAuthService`, `TokenService`, `ClientService`, `ScopeService`
- `oauth2/repositories.py`: `OAuthClientRepository`, `OAuthTokenRepository`, `OAuthUserRepository`
- `oauth2/schemas.py`: `OAuthClientCreate`, `OAuthClientResponse`, `OAuthTokenCreate`, `OAuthTokenResponse`, `OAuthUserCreate`, `OAuthUserResponse`
- `oauth2/dependencies.py`: `get_current_token_payload`, `require_scope`, etc.
- `controllers/admin_controller.py`: pattern for admin routes, session handling, pagination.
- `templates/base.html`: Bootstrap 5 layout with sidebar.
**Bottlenecks & Risks**:
1. **Authorization code storage**: Currently not implemented (TODO in `OAuthService.authorize_code_flow`). Need a simple in-memory or database store for authorization codes with expiration.
2. **User consent UI**: Need a simple HTML page for authorization approval.
3. **Password grant**: Not required; can be omitted or implemented later.
4. **Security**: Must validate redirect_uri, client credentials, scopes, and PKCE (optional future enhancement).

### 2. Router Definitions
#### 2.1 OAuth2 Standard Endpoints (`oauth2/controller.py`)
- **Prefix**: `/oauth`
- **Tags**: `["oauth2"]`
- **Dependencies**: `Depends(get_db)` for database session; no session authentication.
- **Endpoints**:
1. `GET /oauth/authorize` – Authorization endpoint (RFC 6749 §4.1)
2. `POST /oauth/authorize` – Authorization submission (user consent)
3. `POST /oauth/token` – Token endpoint (RFC 6749 §4.1.3, 4.3, 4.4, 6)
4. `GET /oauth/userinfo` – UserInfo endpoint (OpenID Connect Core §5.3)
5. `POST /oauth/introspect` – Token introspection (RFC 7662)
6. `POST /oauth/revoke` – Token revocation (RFC 7009)
7. `GET /.well-known/openid-configuration` – OIDC discovery (optional)
#### 2.2 Admin OAuth2 Management (`controllers/admin_controller.py`)
- **Prefix**: `/admin/oauth`
- **Tags**: `["admin-oauth"]`
- **Dependencies**: Existing session authentication (AuthMiddleware) applies automatically.
- **Endpoints**:
1. `GET /admin/oauth/clients` – List OAuth clients with pagination
2. `GET /admin/oauth/clients/new` – Form to create new client
3. `POST /admin/oauth/clients` – Create new client
4. `GET /admin/oauth/clients/{client_id}/edit` – Edit client form
5. `POST /admin/oauth/clients/{client_id}` – Update client
6. `POST /admin/oauth/clients/{client_id}/delete` – Delete client (soft delete via is_active=False)
7. `GET /admin/oauth/tokens` – List OAuth tokens with filtering (client, user, active/expired)
8. `POST /admin/oauth/tokens/{token_id}/revoke` – Revoke token (delete)
9. `GET /admin/oauth/users` – List OAuth users (optional)
10. `POST /admin/oauth/users/{user_id}/toggle` – Toggle user active status
### 3. Endpoint Specifications
#### 3.1 Authorization Endpoint (`GET /oauth/authorize`)
**Purpose**: Display consent screen to resource owner.
**Parameters** (query string):
- `response_type=code` (only authorization code supported)
- `client_id` (required)
- `redirect_uri` (required, must match registered)
- `scope` (optional)
- `state` (recommended)
- `code_challenge`, `code_challenge_method` (PKCE – optional future)
**Flow**:
1. Validate client_id, redirect_uri, scopes (via OAuthService).
2. If user not authenticated, redirect to login page (reuse admin login? Or separate OAuth user login). For simplicity, we can check if admin session exists; if not, redirect to `/admin/login` with return URL.
3. Render `templates/oauth/authorize_consent.html` with client details and requested scopes.
4. Include hidden inputs for all query parameters.
**Response**: HTML consent page.
#### 3.2 Authorization Submission (`POST /oauth/authorize`)
**Purpose**: Process user consent.
**Parameters** (form data):
- `client_id`, `redirect_uri`, `state`, `scope` (hidden fields)
- `action` (allow/deny)
**Flow**:
1. Validate same parameters again.
2. If action=allow, generate authorization code (store with expiration, client_id, redirect_uri, scopes, user_id if authenticated).
3. Redirect to `redirect_uri` with `code` and `state` (if provided).
4. If action=deny, redirect with `error=access_denied`.
**Response**: 302 Redirect to client's redirect_uri.
#### 3.3 Token Endpoint (`POST /oauth/token`)
**Purpose**: Issue tokens for all grant types.
**Content-Type**: `application/x-www-form-urlencoded`
**Parameters** (depending on grant_type):
- `grant_type` (required): `authorization_code`, `client_credentials`, `refresh_token`, `password` (optional)
- `client_id`, `client_secret` (required for confidential clients, except password grant)
- `code`, `redirect_uri` (for authorization_code)
- `refresh_token` (for refresh_token)
- `username`, `password` (for password grant – optional)
- `scope` (optional)
**Flow**:
1. Validate client credentials (if required) via `ClientService`.
2. Route to appropriate method in `OAuthService`:
- `authorization_code`: validate code, redirect_uri, issue access/refresh tokens.
- `client_credentials`: call `client_credentials_flow`.
- `refresh_token`: call `refresh_token_flow`.
- `password`: (optional) validate user credentials, issue tokens.
3. Return JSON response per RFC 6749 §5.1.
**Response**: JSON with `access_token`, `token_type`, `expires_in`, `refresh_token` (if applicable), `scope`.
#### 3.4 UserInfo Endpoint (`GET /oauth/userinfo`)
**Purpose**: Return claims about authenticated user (OpenID Connect).
**Authentication**: Bearer token with `openid` scope (or any scope). Use dependency `get_current_token_payload`.
**Flow**:
1. Extract token payload (contains `sub`, `client_id`, `scopes`).
2. If token has `user_id`, fetch user details from `OAuthUserRepository`.
3. Return JSON with standard claims (sub, name, email, etc.) as available.
**Response**: JSON with user claims.
#### 3.5 Token Introspection (`POST /oauth/introspect`)
**Purpose**: Validate token and return its metadata (RFC 7662).
**Authentication**: Client credentials via HTTP Basic (or bearer token). Use `ClientService`.
**Parameters**: `token` (required), `token_type_hint` (optional).
**Flow**:
1. Validate client credentials (must be confidential client).
2. Look up token in database via `OAuthTokenRepository`.
3. Return active/expired status, scopes, client_id, user_id, etc.
**Response**: JSON per RFC 7662.
#### 3.6 Token Revocation (`POST /oauth/revoke`)
**Purpose**: Revoke a token (RFC 7009).
**Authentication**: Client credentials via HTTP Basic (or bearer token).
**Parameters**: `token` (required), `token_type_hint` (optional).
**Flow**:
1. Validate client credentials.
2. Revoke token (delete from database) via `TokenService.revoke_token`.
3. Return 200 OK regardless of token existence (RFC 7009).
**Response**: 200 with no body.
#### 3.7 OIDC Discovery (`GET /.well-known/openid-configuration`)
**Purpose**: Provide OpenID Connect discovery metadata.
**Response**: JSON with issuer, authorization/token/userinfo endpoints, supported grant types, scopes, etc.
### 4. Admin Management Endpoints
#### 4.1 OAuth Clients CRUD
- **List**: Paginated table with client ID, name, grant types, redirect URIs, active status, actions (edit, delete).
- **Create/Edit Form**: Fields: client_id, client_secret (plaintext), name, redirect_uris (newline separated), grant_types (checkboxes), scopes (newline separated), is_active (checkbox).
- **Validation**: Use `OAuthClientCreate` schema.
- **Password Hashing**: Hash client_secret with bcrypt before storing (already in repository).
#### 4.2 OAuth Tokens Management
- **List**: Table with access token (truncated), client, user, scopes, expires, active (not expired). Filter by client, user, active/expired.
- **Revoke**: Delete token from database (immediate invalidation).
#### 4.3 OAuth Users Management (optional)
- **List**: Username, email, active status.
- **Toggle active**: Prevent user from obtaining new tokens.
### 5. Template Files Needed
**Templates Structure**:
```
templates/admin/
├── oauth_clients.html
├── oauth_client_form.html
├── oauth_tokens.html
└── oauth_users.html
templates/oauth/
└── authorize_consent.html
```
**Design Guidelines**:
- Extend `base.html` (already includes Bootstrap 5, sidebar).
- Use same styling as existing admin pages (cards, tables, buttons).
- For forms, reuse `admin/endpoint_form.html` pattern (field errors, validation).
### 6. 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 → dict (client_id, redirect_uri, scopes, user_id, expires_at). In production, replace with Redis or database table.
**Interface**:
- `store_code(code, data)`
- `get_code(code) -> Optional[dict]`
- `delete_code(code)`
**Integration**: Update `OAuthService.authorize_code_flow` to store code; add `authorization_code_flow` method to exchange code for tokens.
---
## 🔒 Security & Performance
### Security Considerations
1. **Redirect URI validation**: Exact match (including query parameters?) – follow RFC 6749 (exact match of entire URI).
2. **Client secret hashing**: Already implemented via bcrypt in repository.
3. **Token revocation**: Immediate deletion from database.
4. **Scope validation**: Ensure requested scopes are subset of client's allowed scopes.
5. **CSRF protection**: Use `state` parameter; for authorization POST, check session token (optional).
6. **PKCE**: Future enhancement for public clients (SPA).
7. **HTTPS**: Require in production (configurable).
### Performance
- **Token validation**: Each protected endpoint validates token via database lookup. Ensure indexes on `access_token` and `expires_at`.
- **Authorization code storage**: In‑memory store is fast; consider expiration cleanup job (cron or background task).

## 📋 Instructions for @coder
### Step 1: Create Authorization Code Store
- File: `oauth2/auth_code_store.py`
- Implement `AuthorizationCodeStore` class with async methods using `dict` and `asyncio.Lock`.
- Integrate with `OAuthService` (add dependency).
### Step 2: Implement OAuth2 Controller (`oauth2/controller.py`)
- Create router with prefix `/oauth`.
- Implement each endpoint as async function, delegating to `OAuthService`.
- Use `Depends(get_db)` to get database session.
- For token endpoint, parse `x-www-form-urlencoded` data (`fastapi.Form`).
- For introspection/revocation, implement HTTP Basic authentication (or bearer token).
- Add OIDC discovery endpoint returning static JSON.
### Step 3: Extend Admin Controller (`controllers/admin_controller.py`)
- Add new router with prefix `/admin/oauth`.
- Create route functions similar to existing endpoint CRUD.
- Use existing `templates` directory and `Jinja2Templates`.
- Ensure session authentication works (already covered by AuthMiddleware).
### Step 4: Create HTML Templates
- Copy existing `admin/endpoints.html` pattern for listing.
- Create forms with appropriate fields.
- Use Bootstrap 5 classes.
### Step 5: Update Configuration (`config.py`)
- Add OAuth2 settings with sensible defaults.
- Ensure backward compatibility (existing settings unchanged).
### Step 6: Update App (`app.py`)
- Import and include OAuth2 router.
- Optionally add middleware for CORS if needed.
### Step 7: Test
- Use curl or Postman to test grant flows.
- Verify admin pages load and CRUD works.
---
## 🚨 Error Handling & Validation
- Use `HTTPException` with appropriate status codes (400 for client errors, 401/403 for authentication/authorization).
- Log errors with `logger`.
- Return RFC‑compliant error responses for OAuth2 endpoints (e.g., `error`, `error_description`).
- Validate input with Pydantic schemas (already defined).
---
## 📁 Example Imports & Function Signatures
**`oauth2/controller.py`**:
```python
import logging
from typing import Optional, List
from fastapi import APIRouter, Depends, Request, Form, HTTPException, status
from fastapi.responses import RedirectResponse, JSONResponse
from sqlalchemy.ext.asyncio import AsyncSession
from database import get_db
from oauth2.services import OAuthService, TokenService, ClientService
from oauth2.dependencies import get_current_token_payload
from config import settings
logger = logging.getLogger(__name__)
router = APIRouter(prefix="/oauth", tags=["oauth2"])
@router.get("/authorize")
async def authorize(
request: Request,
response_type: str,
client_id: str,
redirect_uri: str,
scope: Optional[str] = None,
state: Optional[str] = None,
db: AsyncSession = Depends(get_db),
):
# ...
```
**`controllers/admin_controller.py` additions**:
```python
# Add after existing endpoint routes
@router.get("/oauth/clients", response_class=HTMLResponse)
async def list_oauth_clients(
request: Request,
page: int = 1,
db: AsyncSession = Depends(get_db),
):
# ...
```
---
## 📈 Future‑Proofing
- **PKCE support**: Add `code_challenge` validation in authorization and token endpoints.
- **JWT access tokens**: Already implemented; consider adding signature algorithm configuration.
- **Multiple token stores**: Could replace in‑memory code store with Redis.
- **OpenID Connect**: Extend userinfo with standard claims, add `id_token` issuance.
---
**FINAL MISSION**: Deliver a clean, maintainable OAuth2 provider that integrates seamlessly with the existing mock API admin interface, follows established patterns, and is ready for Phase 6.5 (Configuration & Integration).

# Configurable Mock API with Admin Interface - Project Plan
## Architecture Decisions (from @architect)
### Technology Stack
- **Framework**: FastAPI (over Flask) for automatic API documentation, async support, type safety.
- **Server**: Waitress as production WSGI server.
- **Database**: SQLite with SQLAlchemy ORM, aiosqlite for async.
- **Template Engine**: Jinja2 with sandboxed environment.
- **Admin UI**: Custom Jinja2 templates with Bootstrap 5 CDN, session-based authentication.
### Database Schema

- Unique constraint on (route, method).
### Application Architecture
- Repository-Service-Controller pattern with Observer pattern for dynamic route updates.
- Modules: database, models, repositories, services, controllers, observers, schemas, middleware, utils.
### Dynamic Route Registration
- RouteManager service registers/unregisters endpoints at runtime via FastAPI's `add_api_route`.
- Observer pattern triggers route refresh on CRUD operations.
### Template Variable Rendering
- Variable sources: path params, query params, request headers, request body, system variables, endpoint defaults.
- Jinja2 with StrictUndefined to prevent silent failures.
### Admin Interface
- Simple credential store (admin username/password hash from env vars).

# Configurable Mock API with Admin Interface
A lightweight, configurable mock API application in Python that allows dynamic endpoint management via an admin interface. The API serves customizable responses stored in a SQLite database with template variable support.
## Features
- **Dynamic Endpoint Configuration**: Create, read, update, and delete API endpoints through a web-based admin interface.
- **Template Variable Support**: Response bodies can include Jinja2 template variables (e.g., `{{ user_id }}`, `{{ timestamp }}`) populated from path parameters, query strings, headers, request body, system variables, and endpoint defaults.
- **Dynamic Route Registration**: Endpoints are registered/unregistered at runtime without restarting the server.
- **Admin Interface**: Secure web UI with session-based authentication for managing endpoints.
- **Production Ready**: Uses Waitress WSGI server, SQLAlchemy async, and FastAPI with proper error handling and security measures.
## Technology Stack
- **Framework**: FastAPI (with automatic OpenAPI documentation)
- **Server**: Waitress (production WSGI server)
- **Database**: SQLite with SQLAlchemy 2.0 async ORM
- **Templating**: Jinja2 with sandboxed environment
- **Authentication**: Session-based with bcrypt password hashing
- **Frontend**: Bootstrap 5 (CDN) for admin UI

```
## Installation
1. **Navigate to project directory**:
```bash
cd ~/GitLab/customer-engineering/mockapi
```
2. **Create a virtual environment** (recommended):
```bash
python3 -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
```
3. **Install dependencies**:
```bash
pip install -r requirements.txt
```
4. **Configure environment variables**:
```bash
cp .env.example .env
# Edit .env with your settings
```
Example `.env`:
```ini
DATABASE_URL=sqlite+aiosqlite:///./mockapi.db
ADMIN_USERNAME=admin
ADMIN_PASSWORD=admin123 # Change this in production!
SECRET_KEY=your-secret-key-here # Change this!
DEBUG=True # Set to False in production
```
5. **Initialize the database** (tables are created automatically on first run).
## Running the Application
### Development (with auto‑reload)
Make sure your virtual environment is activated:
```bash
source venv/bin/activate # Linux/macOS
# venv\Scripts\activate # Windows
```
Then run with auto-reload for development:
```bash
# Using run.py (convenience script)
python run.py
# Or directly with uvicorn
uvicorn app:app --reload --host 0.0.0.0 --port 8000
```
### Production (with Waitress)
For production deployment, use Waitress WSGI server with the provided WSGI adapter (a2wsgi):
```bash
waitress-serve --host=0.0.0.0 --port=8000 --threads=4 wsgi:wsgi_app
```
The server will start on `http://localhost:8000` (or your configured host/port).
**Note:** Waitress is a WSGI server, but FastAPI is an ASGI framework. The `wsgi.py` file uses `a2wsgi` to wrap the ASGI application into a WSGI-compatible interface. Routes are automatically refreshed from the database on server startup.
## Production Deployment Considerations
### 1. **Environment Configuration**
- Set `DEBUG=False` in production
- Use strong, unique values for `ADMIN_PASSWORD` and `SECRET_KEY`
- Consider using a more robust database (PostgreSQL) by changing `DATABASE_URL`
- Store sensitive values in environment variables or a secrets manager
### 2. **Process Management**
Use a process manager like systemd (Linux) or Supervisor to keep the application running:
**Example systemd service (`/etc/systemd/system/mockapi.service`)**:
```ini
[Unit]
Description=Mock API Service
After=network.target
[Service]
User=www-data
Group=www-data
WorkingDirectory=/path/to/mockapi
Environment="PATH=/path/to/mockapi/venv/bin"
ExecStart=/path/to/mockapi/venv/bin/waitress-serve --host=0.0.0.0 --port=8000 wsgi:wsgi_app
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
```
### 3. **Reverse Proxy (Recommended)**
Use Nginx or Apache as a reverse proxy for SSL termination, load balancing, and static file serving:
**Example Nginx configuration**:
```nginx
server {
listen 80;
server_name api.yourdomain.com;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```
### 4. **Database Backups**
For SQLite, regularly backup the `mockapi.db` file. For production, consider migrating to PostgreSQL.
## Usage
### 1. Access the Admin Interface
- Open `http://localhost:8000/admin/login`
- Log in with the credentials set in `.env` (default: `admin` / `admin123`)
### 2. Create a Mock Endpoint
1. Navigate to **Endpoints** → **Create New**.
2. Fill in the form:
- **Route**: `/api/greeting/{name}` (supports path parameters)
- **Method**: GET
- **Response Body**: `{ "message": "Hello, {{ name }}!" }`
- **Response Code**: 200
- **Content-Type**: `application/json`
- **Variables**: `{ "server": "mock-api" }` (optional defaults)
3. Click **Create**.
### 3. Call the Mock Endpoint
```bash
curl http://localhost:8000/api/greeting/World
```
Response:
```json
{ "message": "Hello, World!" }
```
### 4. Template Variables
The following variable sources are available in response templates:
| Source | Example variable | Usage in template |
|--------|------------------|-------------------|
| Path parameters | `{{ name }}` | `/users/{id}` → `{{ id }}` |
| Query parameters | `{{ query.page }}` | `?page=1` → `{{ page }}` |
| Request headers | `{{ header.authorization }}` | `Authorization: Bearer token` |
| Request body | `{{ body.user.email }}` | JSON request body |
| System variables | `{{ timestamp }}`, `{{ request_id }}` | Automatically injected |
| Endpoint defaults | `{{ server }}` | Defined in endpoint variables |
### 5. Admin Functions
- **List endpoints** with pagination and filtering
- **Edit** existing endpoints (changes take effect immediately)
- **Activate/deactivate** endpoints without deletion
- **Delete** endpoints (removes route)
- **Dashboard** with statistics (total endpoints, active routes, etc.)
## Security Considerations
- **Admin authentication**: Uses bcrypt password hashing. Store a strong password hash in production.
- **Session management**: Signed cookies with configurable secret key.
- **Template sandboxing**: Jinja2 environment restricted with `SandboxedEnvironment` and `StrictUndefined`.
- **Request size limits**: Maximum body size of 1MB to prevent DoS.
- **Route validation**: Prevents path traversal (`..`) and other unsafe patterns.
- **SQL injection protection**: All queries use SQLAlchemy ORM.
## Configuration Options
See `config.py` for all available settings. Key environment variables:
| Variable | Default | Description |
|----------|---------|-------------|
| `DATABASE_URL` | `sqlite+aiosqlite:///./mockapi.db` | SQLAlchemy database URL |
| `ADMIN_USERNAME` | `admin` | Admin login username |
| `ADMIN_PASSWORD` | `admin123` | Admin login password (plaintext) |
| `SECRET_KEY` | `your‑secret‑key‑here‑change‑me` | Session signing secret |
| `DEBUG` | `False` | Enable debug mode (more logging, relaxed validation) |
**Warning**: In production (`DEBUG=False`), the default `ADMIN_PASSWORD` and `SECRET_KEY` will cause validation errors. You must set unique values via environment variables.
## API Documentation
FastAPI automatically provides OpenAPI documentation at:
- Swagger UI: `http://localhost:8000/docs`
- ReDoc: `http://localhost:8000/redoc`
The root URL (/) automatically redirects to the Swagger documentation at /docs.
The dynamic mock endpoints are not listed in the OpenAPI schema (they are registered at runtime).
## Development & Testing
### Running Tests
Run tests with pytest:
```bash
pytest tests/
```
The test suite includes:
- Unit tests for repository and service layers
- Integration tests for admin authentication
- Template rendering tests
### Example Integration Test
A ready‑to‑run integration test demonstrates the core functionality:
```bash
# Make the script executable (Linux/macOS)
chmod +x run_example.sh
# Run the example
./run_example.sh
```
Or directly with Python:
```bash
python example_usage.py
```
The example script will:
1. Start the FastAPI app (via TestClient)
2. Log in as admin
3. Create a mock endpoint with template variables
4. Call the endpoint and verify the response
5. Report success or failure
This is a great way to verify that the API is working correctly after installation.
## Troubleshooting
### Common Issues
1. **"no such table: endpoints" error**
- The database hasn't been initialized
- Restart the application - tables are created on first startup
- Or run `python -c "from database import init_db; import asyncio; asyncio.run(init_db())"`
2. **Login fails even with correct credentials**
- Check that `DEBUG=True` is set in `.env` (or provide unique credentials)
- The default credentials only work when `DEBUG=True`
- In production, you must set unique `ADMIN_PASSWORD` and `SECRET_KEY`
3. **Routes not being registered**
- Check that the endpoint is marked as active (`is_active=True`)
- Refresh the page - routes are registered immediately after creation
- Check application logs for errors
4. **Template variables not rendering**
- Ensure you're using double curly braces: `{{ variable }}`
- Check variable names match the context (use path_, query_, header_ prefixes as needed)
- View the rendered template in the admin edit form preview
### Logging
Enable debug logging by setting `DEBUG=True` in `.env`. Check the console output for detailed error messages.
## Limitations & Future Enhancements
- **Current limitations**:
- SQLite only (but can be extended to PostgreSQL via `DATABASE_URL`)
- Single admin user (no multi‑user support)
- No request logging/history
- **Possible extensions**:
- Import/export endpoints as JSON/YAML
- Request logging and analytics
- WebSocket notifications for admin actions
- Multiple admin users with roles
- Rate limiting per endpoint
- CORS configuration

# Technical Specification: OAuth2 Controllers (Phase 6.4)
## Overview
This document provides the implementation blueprint for OAuth2 controllers in the Configurable Mock API application. The implementation follows the existing Repository-Service-Controller pattern and integrates with the admin interface.
## 1. File Structure
### New Files
- `oauth2/controller.py` – OAuth2 standard endpoints (RFC 6749, 7662, 7009, OIDC)
- `oauth2/auth_code_store.py` – In‑memory storage for authorization codes
- `templates/admin/oauth_clients.html` – List OAuth clients
- `templates/admin/oauth_client_form.html` – Create/edit client form
- `templates/admin/oauth_tokens.html` – List OAuth tokens
- `templates/admin/oauth_users.html` – List OAuth users (optional)
- `templates/oauth/authorize_consent.html` – Authorization consent page
### Modified Files
- `controllers/admin_controller.py` – Add admin OAuth2 management routes under `/admin/oauth`
- `config.py` – Add OAuth2 configuration settings
- `app.py` – Include OAuth2 router
## 2. OAuth2 Standard Endpoints
### Router: `/oauth`
| Endpoint | Method | Purpose |
|----------|--------|---------|
| `/oauth/authorize` | GET | Display consent screen |
| `/oauth/authorize` | POST | Process consent |
| `/oauth/token` | POST | Issue tokens (all grant types) |
| `/oauth/userinfo` | GET | Return user claims (OpenID Connect) |
| `/oauth/introspect` | POST | Token introspection (RFC 7662) |
| `/oauth/revoke` | POST | Token revocation (RFC 7009) |
| `/.well-known/openid-configuration` | GET | OIDC discovery metadata |
### Dependencies
- Database session: `Depends(get_db)`
- Token validation: `get_current_token_payload` (for userinfo)
- Client authentication: HTTP Basic for introspection/revocation
## 3. Admin OAuth2 Management Endpoints
### Router: `/admin/oauth`
| Endpoint | Method | Purpose |
|----------|--------|---------|
| `/admin/oauth/clients` | GET | List clients (paginated) |
| `/admin/oauth/clients/new` | GET | Create client form |
| `/admin/oauth/clients` | POST | Create client |
| `/admin/oauth/clients/{client_id}/edit` | GET | Edit client form |
| `/admin/oauth/clients/{client_id}` | POST | Update client |
| `/admin/oauth/clients/{client_id}/delete` | POST | Deactivate client |
| `/admin/oauth/tokens` | GET | List tokens with filters |
| `/admin/oauth/tokens/{token_id}/revoke` | POST | Revoke token |
| `/admin/oauth/users` | GET | List users (optional) |
### Authentication
- Protected by existing `AuthMiddleware` (session‑based).
## 4. Configuration Additions (`config.py`)
```python
# Add to Settings class
oauth2_issuer: str = "http://localhost:8000"
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"
]
```
## 5. 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`.
