MS访问:跨多个表单事件保持持久会话的方法？

from flask import Flask, request, make_response, session

app = Flask(__name__)
app.secret_key = 'your_secret_key'  # 设置一个安全的密钥

@app.route('/login', methods=['POST'])
def login():
    username = request.form['username']
    password = request.form['password']
    
    # 验证用户名和密码
    if username == 'admin' and password == 'password':
        session['username'] = username  # 创建会话
        response = make_response('Logged in successfully')
        response.set_cookie('session_id', value=session.sid, max_age=3600)  # 设置持久性Cookie
        return response
    else:
        return 'Invalid credentials'

@app.route('/profile')
def profile():
    if 'username' in session:
        return f'Hello, {session["username"]}!'
    else:
        return 'You are not logged in'

@app.route('/logout')
def logout():
    session.pop('username', None)  # 销毁会话
    response = make_response('Logged out successfully')
    response.delete_cookie('session_id')  # 删除Cookie
    return response

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