Welcome to our Betting Web Service API assignment! In this assignment, we'll be developing a web service API for a betting platform that allows users to place bets on various games. This assignment will assess the ability to design and implement a RESTful API using Rust and the Axum web framework. Please read the instructions below to get started.
To complete this assignment, you will need the following:
- Rust programming language installed on your machine.
- Basic understanding of JSON for data serialization.
- Familiarity with web development concepts, RESTful APIs, and HTTP protocols.
Your task is to design and implement a RESTful API for a betting platform. You are required to implement the following endpoints:
POST /api/users- Create a new user account.POST /api/authenticate- Authenticate a user and retrieve an access token.GET /api/games- Retrieve the list of available games.POST /api/bets- Place a bet on a game.GET /api/bets- Retrieve the details of a user's bets.GET /api/games/:game_id/results- Retrieve the results of a specific game.GET /api/leaderboard- Retrieve the leaderboard of top users.GET /api/users/:user_id: Retrieves the details of a specific user based on their userId.GET /api/profile: Retrieves the details the current user.PUT /api/profile: Updates the user's information, such as username, password, or other profile details.DELETE /api/profile: Deletes the user's account and associated data from the system.GET /api/games/:game_id/bets: Retrieves the list of bets placed on a specific game.PUT /api/bets/:bet_id: Updates an existing bet, allowing users to modify the amount or other details.DELETE /api/bets/:bet_id: Cancels a specific bet made by a user.GET /api/games/:game_id/participants: Retrieves the list of participants involved in a specific game.POST /api/games/:game_id/results: Sets the results of a specific game, allowing authorized users to declare the outcome or winner.
