Personal Fitness ChatBot (Version 1) 2 | 3 | ## Description 4 | 5 | This project is a FastAPI-based web application. It is designed to provide a secure conversation platform for registered users. The main functionality of this version is to authenticate the user and return a static conversation message. 6 | 7 | ## Setup 8 | 9 | This project uses FastAPI and SQLAlchemy, and it requires Python 3.7+. 10 | 11 | To start the application, navigate to the project folder and execute the command: 12 | 13 | python main.py 14 | 15 | The application will be available at `http://localhost:5555`. 16 | 17 | ## Key Features 18 | 19 | - User registration and authentication system with OAuth2. 20 | - Secure conversation endpoint that returns a static message and the authenticated user's username. 21 | - SQLite database for user data persistence. 22 | 23 | ## Environment Variables 24 | 25 | To run this project, you will need to add the following environment variable: 26 | 27 | - `SECRET_KEY`: Your secret key for encoding and decoding the JWT tokens. 28 | 29 | Please use a `.env` file for setting this environment variable. The `.env` file is ignored by git to ensure sensitive items are not accidentally published. 30 | -------------------------------------------------------------------------------- /app/__init__.py:
