Python을 사용하여 CMS 시스템의 사용자 로그인 및 등록 기능을 구현하는 방법

from flask import Flask, render_template, request, redirect

app = Flask(__name__)

# 用户信息存储
users = []

@app.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        
        # 检查用户名是否已存在
        for user in users:
            if user['username'] == username:
                return '该用户名已存在'
        
        # 创建新用户
        new_user = {
            'username': username,
            'password': password
        }
        users.append(new_user)
        
        return '注册成功'
    
    return render_template('register.html')
