# Story 1.4: Internal API Foundation - COMPLETED
|
||||
|
||||
## Overview
|
||||
Implemented a secure REST API foundation with FastAPI, including HTTP Basic Authentication, role-based access control, and comprehensive test coverage.
|
||||
|
||||
## Story Details
|
||||
**As a developer**, I want to create a basic, secured REST API endpoint, so that the foundation for inter-service communication is established.
|
||||
|
||||
## Acceptance Criteria - ALL MET
|
||||
|
||||
### 1. Basic REST API Created
|
||||
**Status:** COMPLETE
|
||||
|
||||
A FastAPI application is created within the src/api module:
|
||||
- Location: `src/api/main.py`
|
||||
- Framework: FastAPI v0.104.1
|
||||
- Automatic OpenAPI documentation at `/docs` and `/openapi.json`
|
||||
- Clean separation of concerns with modular structure
|
||||
|
||||
### 2. Health Check Endpoint
|
||||
**Status:** COMPLETE
|
||||
|
||||
A simple health check endpoint is available:
|
||||
- Endpoint: `GET /health`
|
||||
- Returns: `{"status": "healthy", "message": "API is running"}`
|
||||
- Status Code: 200 OK
|
||||
- No authentication required (public endpoint)
|
||||
- Useful for monitoring and deployment health checks
|
||||
|
||||
### 3. API Endpoints Require Authentication
|
||||
**Status:** COMPLETE
|
||||
|
||||
All API endpoints (except public `/health`) require authentication:
|
||||
- Authentication Method: HTTP Basic Authentication
|
||||
- Credentials validated against database
|
||||
- Password verification using bcrypt
|
||||
- Returns 401 Unauthorized for invalid credentials
|
||||
- WWW-Authenticate header included in 401 responses
|
||||
|
||||
### 4. API Designed for Extensibility
|
||||
**Status:** COMPLETE
|
||||
|
||||
The API is designed with future growth in mind:
|
||||
- Versioned endpoints (`/api/v1/...`)
|
||||
- Modular structure (main.py, routes.py, schemas.py)
|
||||
- Dependency injection for services
|
||||
- Role-based access control (Admin vs User)
|
||||
- Pydantic schemas for request/response validation
|
||||
- FastAPI dependency system for reusable auth logic
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Files Created/Modified
|
||||
|
||||
#### 1. `src/api/main.py` - NEW
|
||||
```python
|
||||
class FastAPI application with authentication dependencies:
|
||||
- app: FastAPI application instance
|
||||
- security: HTTPBasic security scheme
|
||||
- get_auth_service() -> AuthService: Dependency for auth service
|
||||
- get_current_user() -> User: Dependency for authenticated endpoints
|
||||
- get_current_admin_user() -> User: Dependency for admin-only endpoints
|
||||
```
|
||||
|
||||
**Key Features:**
|
||||
- HTTP Basic Authentication using FastAPI security
|
||||
- Dependency injection for authentication
|
||||
- Clean separation between regular and admin authentication

|
||||
```python
|
||||
API endpoint definitions:
|
||||
Public Endpoints:
|
||||
- GET /health: Health check endpoint
|
||||
|
||||
Authenticated Endpoints:
|
||||
- GET /api/v1/me: Get current user information
|
||||
|
||||
Admin-Only Endpoints:
|
||||
- GET /api/v1/admin/status: Admin status check
|
||||
```
|
||||
|
||||
**Endpoint Features:**
|
||||
- Full OpenAPI documentation
|
||||
- Pydantic response models
|
||||
- Proper HTTP status codes
|
||||
- Security requirements documented

||||
- Tag-based organization
|
||||
|
||||
#### 3. `src/api/schemas.py` - NEW
|
||||
```python
|
||||
Pydantic models for API validation:
|
||||
- LoginRequest: Login credentials
|
||||
- UserResponse: User information response
|
||||
- LoginResponse: Successful login response
|
||||
- ErrorResponse: Error message response
|
||||
- HealthResponse: Health check response
|
||||
```
|
||||
|
||||
**Schema Features:**
|
||||
- Field validation using Pydantic
|
||||
- from_attributes configuration for ORM compatibility
|
||||
- Detailed field descriptions
|
||||
- Type safety
|
||||
|
||||
#### 4. `src/api/__init__.py` - UPDATED
|
||||
- Exports app instance
|
||||
- Imports routes to register them
|
||||
- Includes documentation on running the API
|
||||
|
||||
#### 5. `requirements.txt` - UPDATED
|
||||
- Added `httpx==0.25.2` for FastAPI TestClient support
|
||||
|
||||
### Endpoints
|
||||
|
||||
#### Public Endpoints
|
||||
|
||||
**GET /health**
|
||||
- No authentication required
|
||||
- Returns health status
|
||||
- Response: `{"status": "healthy", "message": "API is running"}`
|
||||
- Use case: Load balancer health checks, monitoring
|
||||
|
||||
#### Authenticated Endpoints
|
||||
|
||||
**GET /api/v1/me**
|
||||
- Requires: HTTP Basic Authentication
|
||||
- Returns: Current user information (id, username, role)
|
||||
- Status: 200 OK on success, 401 on auth failure
|
||||
- Use case: Get information about authenticated user
|
||||
|
||||
#### Admin-Only Endpoints
|
||||
|
||||
**GET /api/v1/admin/status**
|
||||
- Requires: HTTP Basic Authentication + Admin role
|
||||
- Returns: Admin status information
|
||||
- Status: 200 OK for admins, 403 for non-admins, 401 for unauthenticated
|
||||
- Use case: Admin dashboard, system status
|
||||
|
||||
### Authentication Flow
|
||||
|
||||
1. Client sends request with HTTP Basic Auth header
|
||||
2. FastAPI extracts credentials using `HTTPBasic` dependency
|
||||
3. `get_auth_service()` provides AuthService instance
|
||||
4. `get_current_user()` validates credentials against database
|
||||
5. On success: User object passed to endpoint
|
||||
6. On failure: 401 Unauthorized returned
|
||||
|
||||
### Role-Based Access Control
|
||||
|
||||
The API implements two-tier authorization:
|
||||
|
||||
**Regular User Access:**
|
||||
- `get_current_user()` dependency
|
||||
- Validates authentication only
|
||||
- Allows access to user-level endpoints
|
||||
|
||||
**Admin Access:**
|
||||
- `get_current_admin_user()` dependency
|
||||
- Validates authentication AND admin role
|
||||
- Returns 403 Forbidden if user is not admin
|
||||
- Allows access to admin-only endpoints
|
||||
|
||||
### Test Coverage
|
||||
|
||||
#### Unit Tests (`tests/unit/test_api_endpoints.py`)
|
||||
- 16 test cases covering all endpoint scenarios
|
||||
- Tests using mocked dependencies
|
||||

### Running the API
|
||||
|
||||
**Development Server:**
|
||||
```bash
|
||||
uvicorn src.api.main:app --reload --host 0.0.0.0 --port 8000
|
||||
```
|
||||
|
||||
**Production Server:**
|
||||
```bash
|
||||
uvicorn src.api.main:app --host 0.0.0.0 --port 8000 --workers 4
|
||||
```
|
||||
|
||||
**Testing with curl:**
|
||||
```bash
|
||||
# Health check (no auth)
|
||||
curl http://localhost:8000/health
|
||||
|
||||
# Get current user (with auth)
|
||||
curl -u username:password http://localhost:8000/api/v1/me
|
||||
|
||||
# Admin endpoint (with admin auth)
|
||||
curl -u admin:password http://localhost:8000/api/v1/admin/status
|
||||
```
|
||||
|
||||
## Dependencies
|
||||
|
||||
- `fastapi==0.104.1` - Web framework
|
||||
- `uvicorn[standard]==0.24.0` - ASGI server
|
||||
- `httpx==0.25.2` - HTTP client for testing
|
||||
- `pydantic==2.5.0` - Data validation
|
||||
- `passlib[bcrypt]==1.7.4` - Password hashing
|
||||

|
||||
|
||||
## Testing Commands
|
||||
|
||||
```bash
|
||||
# Run all API tests
|
||||
.venv/Scripts/python -m pytest tests/unit/test_api_endpoints.py tests/integration/test_api_integration.py -v
|
||||
|
||||
# Run unit tests only
|
||||
.venv/Scripts/python -m pytest tests/unit/test_api_endpoints.py -v
|
||||
|
||||
# Run integration tests only
|
||||
.venv/Scripts/python -m pytest tests/integration/test_api_integration.py -v
|
||||
|
||||
# Run with coverage
|
||||
.venv/Scripts/python -m pytest tests/unit/test_api_endpoints.py tests/integration/test_api_integration.py --cov=src/api --cov-report=html
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
This API foundation is now ready for:
|
||||
- **Story 1.5**: Command-Line User Management (CLI will use API internally)
|
||||
- **Epic 2**: Content Generation endpoints
|
||||
- **Epic 4**: Job transmission endpoints for link-building machine
|
||||
- Future feature endpoints (content ingestion, interlinking, etc.)
|
||||
|
||||
## Extensibility Examples
|
||||
|
||||
### Adding a New Endpoint
|
||||
|
||||
```python
|
||||
# In src/api/routes.py
|
||||
@app.get("/api/v1/projects", response_model=List[ProjectResponse])
|
||||
async def list_projects(current_user: User = Depends(get_current_user)):
|
||||
"""List all projects for the current user"""
|
||||
# Implementation here
|
||||
pass
|
||||
```
|
||||
|
||||
### Adding Admin-Only Endpoint
|
||||
|
||||
```python
|
||||
# In src/api/routes.py
|
||||
@app.post("/api/v1/admin/users", response_model=UserResponse)
|
||||
async def create_user(
|
||||
user_data: CreateUserRequest,
|
||||
current_admin: User = Depends(get_current_admin_user)
|
||||
):
|
||||
"""Create a new user (admin only)"""
|
||||
# Implementation here
|
||||
pass
|
||||
```
|
||||
|
||||
### Adding Request Validation
|
||||
|
||||
```python
|
||||
# In src/api/schemas.py
|
||||
class CreateProjectRequest(BaseModel):
|
||||
name: str = Field(..., min_length=3, max_length=100)
|
||||
description: Optional[str] = Field(None, max_length=500)
|
||||
tier: str = Field(..., pattern="^(Tier1|Tier2|Tier3)$")
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
- The API uses HTTP Basic Auth for MVP simplicity
|
||||
- Future enhancements could include:
|
||||
- JWT tokens for stateless authentication
|
||||
- OAuth2 for third-party integrations
|
||||
- API keys for machine-to-machine communication
|
||||
- Rate limiting
|
||||
- CORS configuration for web clients
|
||||
- All API responses use Pydantic models for type safety
|
||||
- The dependency injection system makes testing easy
|
||||
- FastAPI's async support enables high performance
|
||||
- OpenAPI documentation makes API self-documenting
|
||||
|
||||
