Question

我正在使用在pythonanywhere.com上托管的Flask在网上构建聊天机器人应用程序但是，当不止一个人同时与机器人聊天时，他们的问题会相互干扰并且机器人在上下文中回答最近的一个问题。

我尝试使用Flask中的会话分离相关数据，但我看到了同样的问题。我阅读了文档并看过许多使用用户名或电子邮件的示例，但在我的情况下，我想随机生成会话ID，然后让该用户的所有相关数据仅与其实例相关。

我知道我需要来自this question的密钥我对文档和other questions的一般用法有基本的了解我知道最好远离这些类型的应用程序的全局变量from this question

我认为每个浏览器请求会自动分隔会话及其数据，但我必须遗漏一些东西。我在这里发布了代码的主要部分。如果我的问题解释不清楚，您可以通过与不同浏览器的机器人聊天，在youngblksocrates.pythonanywhere.com看到问题。非常感谢！

感谢您的时间和抱歉这个罗嗦的问题！

Answer 1

我四处询问并发现如果文件的顶层有变量，那么每次请求都会覆盖它们。

由于数据存储在currentProfile和learnBoutClass变量中，我从顶层删除了这些变量，并将其替换为会话字典中的变量：session['profiledata']和session['scriptdata']

这解决了最初的问题。

跨客户端的Python Flask会话数据不是分开的
