How to design a system that supports learning games and competition rankings in online quizzes

With the development of network technology, online learning has become an increasingly Universal learning styles. As one of the forms, online question answering makes learning more flexible and interesting. In order to stimulate students' interest in learning and awareness of competition, it is necessary to design a system that supports learning games and competition rankings in online quizzes. This article describes how to design such a system and provides some concrete code examples.

1. System requirements analysis

Before starting the system design, it is necessary to conduct a requirements analysis to clarify the system functions and user requirements. According to the system of online quiz learning games and competition rankings, we can list the following main functional requirements:

• User registration and login: Users need to register an account first and log in to the system through the account.
• Personal information management: Users can manage their personal information, such as changing passwords, updating personal information, etc.
• Learning games: The system provides a certain number of learning games, and users can choose to practice according to their own learning needs.
• Competition ranking: Users can participate in competitions in the system and check their position in the rankings.
• Points and rewards: The system gives different points and rewards based on the user’s academic performance and participation.

2. System design and code examples

2.1 User registration and login

User registration and login are the basic functions of the system. The following is a simple registration and Login code example (using Python and Flask framework):

from flask import Flask, request, redirect, render_template
from werkzeug.security import generate_password_hash, check_password_hash

app = Flask(__name__)

# 用户信息存储（可以使用数据库或者其他持久化存储方式）
users = []

# 用户注册
@app.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        # 对密码进行加密存储
        password_hash = generate_password_hash(password)
        
        # 将用户信息保存到数据库中
        users.append({'username': username, 'password_hash': password_hash})
        
        return redirect('/login')
    return render_template('register.html')

# 用户登录
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        
        # 根据用户名从数据库中获取用户信息
        user = next((u for u in users if u['username'] == username), None)
        
        # 检查密码是否正确
        if user and check_password_hash(user['password_hash'], password):
            return redirect('/')
        
        return render_template('login.html', error='Invalid username or password')
    
    return render_template('login.html')
