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')
