Real Usage Examples

Authentication Methods

Basic Authentication

import base64  
from flask import Flask, request, jsonify

app = Flask(__name__)

# Function to check user credentials for Basic Authentication

def check_auth(username, password):
    return username == 'admin' and password == 'secret'

@app.route('/secure-data')
def secured_endpoint():
    auth = request.authorization
    if not auth or not check_auth(auth.username, auth.password):
        return jsonify({'message': 'Authentication required!'}), 401
    return jsonify({'message': 'Secure data accessible'})  # Example response

Additional Information

Make sure to implement HTTPS for secure communication and consider various authentication methods suitable for your architecture, such as OAuth or JWT.
