To implement API authentication and authorization protocols using Auth0, JWT, and Azure API Management, we need to configure the necessary settings, integrate Auth0 for authentication, use JWT for token-based authorization, and set up Azure API Management for security. This involves updating several files to ensure secure authentication and authorization for the APIs.
How to implement
Step 1: Configure Auth0 for Authentication
File: backend-container/flaskapp/config.py
Add the necessary configuration settings for Auth0, including AUTH0_CLIENT_ID, AUTH0_CLIENT_SECRET, and AUTH0_DOMAIN.
import os
from dotenv import load_dotenv
import logging
# Load environment variables from .env file
dotenv_path = os.path.join(os.path.dirname(__file__), '../.env')
load_dotenv(dotenv_path)
class ConfigurationError(Exception):
pass
# Base Configuration
class Config:
DEBUG = False
TESTING = False
connection_string = os.getenv('MONGODB_URL')
if not connection_string:
raise ConfigurationError(
"MONGODB_URL must be set in .env or environment variables")
MONGODB_SETTINGS = {
'db': 'Current_Season',
'host': connection_string,
'maxPoolSize': 50,
'minPoolSize': 5
}
LOGGING_LEVEL = logging.ERROR
# Auth0 Configuration
AUTH0_CLIENT_ID = os.getenv('AUTH0_CLIENT_ID')
AUTH0_CLIENT_SECRET = os.getenv('AUTH0_CLIENT_SECRET')
AUTH0_DOMAIN = os.getenv('AUTH0_DOMAIN')
if not AUTH0_CLIENT_ID or not AUTH0_CLIENT_SECRET or not AUTH0_DOMAIN:
raise ConfigurationError(
"AUTH0_CLIENT_ID, AUTH0_CLIENT_SECRET, and AUTH0_DOMAIN must be set in .env or environment variables")
class DevelopmentConfig(Config):
DEBUG = True
TESTING = True
LOGGING_LEVEL = logging.DEBUG
class ProductionConfig(Config):
DEBUG = False
TESTING = False
LOGGING_LEVEL = logging.WARNINGStep 2: Enhance Logging for Authentication and Authorization
File: backend-container/src/utils/logandcatchexceptions.py
Add specific logging functions for authentication and authorization events.
from functools import wraps
from src.utils.log import be_logger
def log_and_catch_exceptions(func):
@wraps(func)
def func_wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except Exception as e:
be_logger.error(f"Exception in {func.__name__}: {e}")
raise
return func_wrapper
def log_authentication_event(event, user_info=None):
if user_info:
be_logger.info(f"Authentication event: {event} for user: {user_info}")
else:
be_logger.info(f"Authentication event: {event}")
def log_authorization_event(event, user_info=None):
if user_info:
be_logger.info(f"Authorization event: {event} for user: {user_info}")
else:
be_logger.info(f"Authorization event: {event}")
# Example usage in authentication and authorization functions
def authenticate_user(user_credentials):
log_authentication_event("User login attempt", user_credentials.get('username'))
# Authentication logic here
log_authentication_event("User login successful", user_credentials.get('username'))
def authorize_user(user, resource):
log_authorization_event("Authorization check", user.get('username'))
# Authorization logic here
log_authorization_event("Authorization granted", user.get('username'))Step 3: Enhance Error Handling for Authentication and Authorization
File: backend-container/src/utils/errorhandler.py
Add specific error handlers for authentication and authorization errors.
from flask import jsonify
from werkzeug.exceptions import Unauthorized, Forbidden
@app.errorhandler(Exception)
def handle_exception(e):
be_logger.exception("An error occurred: %s", e)
return str(e), 500
@app.errorhandler(Unauthorized)
def handle_unauthorized(e):
be_logger.warning("Unauthorized access attempt: %s", e)
response = jsonify({
"error": "unauthorized",
"message": "You are not authorized to access this resource. Please check your credentials."
})
return response, 401
@app.errorhandler(Forbidden)
def handle_forbidden(e):
be_logger.warning("Forbidden access attempt: %s", e)
response = jsonify({
"error": "forbidden",
"message": "You do not have permission to access this resource."
})
return response, 403
@app.errorhandler(jwt.ExpiredSignatureError)
def handle_expired_token(e):
be_logger.warning("Expired token: %s", e)
response = jsonify({
"error": "token_expired",
"message": "Your session has expired. Please log in again."
})
return response, 401
@app.errorhandler(jwt.InvalidTokenError)
def handle_invalid_token(e):
be_logger.warning("Invalid token: %s", e)
response = jsonify({
"error": "invalid_token",
"message": "The provided token is invalid. Please log in again."
})
return response, 401Step 4: Implement JWT Token Management
File: backend-container/src/utils/jwt.py
Implement functions to create, verify, and manage JWT tokens securely.
import jwt
import datetime
from typing import Dict, Any
# Constants
SECRET_KEY = 'your_secret_key' # Replace with your actual secret key
ALGORITHM = 'HS256'
def create_token(data: Dict[str, Any], expires_in: int = 3600) -> str:
payload = data.copy()
payload['exp'] = datetime.datetime.utcnow() + datetime.timedelta(seconds=expires_in)
token = jwt.encode(payload, SECRET_KEY, algorithm=ALGORITHM)
return token
def verify_token(token: str) -> Dict[str, Any]:
try:
decoded_data = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM])
return decoded_data
except jwt.ExpiredSignatureError:
raise ValueError("Token has expired")
except jwt.InvalidTokenError:
raise ValueError("Invalid token")
def decode_token(token: str) -> Dict[str, Any]:
decoded_data = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM], options={"verify_exp": False})
return decoded_dataStep 5: Implement Auth0 Authentication in Flask
File: backend-container/src/utils/auth.py
Implement the required API authentication and authorization protocols using Auth0.
from flask import Blueprint, redirect, url_for, session
from authlib.integrations.flask_client import OAuth

if ENV_FILE := find_dotenv():
load_dotenv(ENV_FILE)
# Blueprint for authentication routes
auth_blueprint = Blueprint('auth_blueprint', __name__)
auth_blueprint.secret_key = os.getenv("APP_SECRET_KEY")
def init_oauth(app):
global oauth
oauth = OAuth()
oauth.init_app(app)
oauth.register(
"auth0",
client_id=os.getenv("AUTH0_CLIENT_ID"),
client_secret=os.getenv("AUTH0_CLIENT_SECRET"),
client_kwargs={
"scope": "openid profile email",
},
server_metadata_url=f'https://{os.getenv("AUTH0_DOMAIN")}/.well-known/openid-configuration'
)
@auth_blueprint.route("/login")
def login():
return oauth.auth0.authorize_redirect(
redirect_uri=url_for("auth_blueprint.callback", _external=True)
)
@auth_blueprint.route("/callback", methods=["GET", "POST"])
def callback():
token = oauth.auth0.authorize_access_token()
session["user"] = token
return redirect("/")
@auth_blueprint.route("/logout")
def logout():
session.clear()
return redirect(
"https://" + os.getenv("AUTH0_DOMAIN")
+ "/v2/logout?"
+ urlencode(
{
"returnTo": url_for("home", _external=True),
"client_id": os.getenv("AUTH0_CLIENT_ID"),
},
quote_via=quote_plus,
)
)
@auth_blueprint.route("/")

This guide will help you set up the environment using GitHub Codespaces or set it up locally using Docker and Docker Compose. Be aware the application is half built right now. It needs quite a bit of TLC. This is my first project, feel free to criticize and make recommendations as you see fit!
## NFLSTATS Development Environment Setup Guide
Welcome to the NFLSTATS project! This guide will walk you through setting up your development environment to run the application locally. Before diving into the setup process, ensure you have the following prerequisites installed on your machine:
### Prerequisites
- Git: For cloning the repository. Download and install from Git's official site.
- Docker: Required for running the application's containers. Download and install Docker from Docker's official site.
- Docker Compose: For managing multi-container Docker applications. Typically included with Docker Desktop installations.
- Node.js: The runtime environment for the application. Download and install from Node.js's official site.
- npm: Comes with Node.js and is used for managing dependencies.
- Visual Studio Code (Optional): Recommended IDE for editing and debugging the application. Download from Visual Studio Code's official site.
### Environment Setup
#### Clone the Repository
First, clone the NFLSTATS repository to your local machine using Git:
```sh
git clone https://github.com/[your_username]/nflstats.gitReplace [your_username] with your GitHub username if you have forked the repository. Otherwise, use the project's main repository URL.
Docker Environment
Ensure Docker and Docker Compose are installed and running on your machine. The application uses Docker containers for both development (docker-compose.debug.yml) and production (docker-compose.prod.yml) environments.
Node.js and npm Packages
After cloning the repository, navigate to the project directory and install the required npm packages:
cd nflstats
npm installThis command installs all dependencies defined in package.json.
Environment Variables
The application requires several environment variables to be set. These variables can be found and modified in the .env files located in the project root or specific directories for different environments (e.g., .env.development, .env.production). Ensure all necessary variables are set before proceeding.
Running the Application for Development
With all prerequisites installed and environment variables set, you can start the development server using npm scripts defined in package.json:
npm run start:devThis command executes the start:dev script, which builds the application for development and starts the development server. If everything is set up correctly, the application should now be running and accessible.
Accessing the Application
Once the application is running, you can access it by navigating to http://localhost:3000 in your web browser, assuming the default port configuration.
Additional Information
Dockerfiles
If the Dockerfiles are on .dockerignore, ensure to remove them from the ignore list or manually copy them into your project directory. The Dockerfiles are crucial for building the Docker images for both development and production environments.
Scripts
For detailed information on available npm scripts and their purposes, refer to the scripts section in package.json. These scripts provide shortcuts for common tasks such as building the application, starting the development server, and cleaning the build directory.
Contributing
Contributions to the NFLSTATS project are welcome! Please refer to the project's CONTRIBUTING.md file for guidelines on how to contribute.
