在Python中通过打开的登录表单保存web会话

from flask import Flask, request, session

app = Flask(__name__)

app.secret_key = 'your_secret_key'

@app.route('/login', methods=['POST'])
def login():
    # 获取表单数据
    username = request.form['username']
    password = request.form['password']
    
    # 验证用户名和密码
    if username == 'admin' and password == 'password':
        # 保存用户的登录状态到会话中
        session['logged_in'] = True
        session['username'] = username
        return 'Login successful'
    else:
        return 'Invalid username or password'

@app.route('/protected')
def protected():
    if 'logged_in' in session and session['logged_in']:
        return 'Protected content'
    else:
        return 'Access denied'

if __name__ == '__main__':
    app.run()
