会话在本地主机上的两个Flask应用之间共享 [英] Session is shared between two Flask apps on localhost

问题描述

因此，我有两个在本地主机上运行的Flask应用程序，一个在端口5001上运行，另一个在端口5003上运行，显然两者都使用相同的会话.如果我登录一个应用程序，则退出另一个应用程序.例如，最近，如果我在一个应用程序上使用电子邮件登录，它也会在另一个应用程序上登录我的帐户，因为我有用户在两个应用程序上都使用该电子邮件，并且我将电子邮件用作用户标识，但是当我为用户使用另一个ID时，这种情况就停止了.

So, I have two Flask apps running on localhost, one on the port 5001, and the other one on the port 5003, and apparently both are using the same session. If I log in on one app, it logs out on the other. And for example, recently, if I logged in using my email on one app, it would also log in my account on the other app, since I have users using that email on both apps, and I was using the email as an user identifier, but that stop happening when I used another id for the users.

我正在使用Flask-Login和Google Chrome(在Edge中也是如此).

I'm using Flask-Login, and Google Chrome (the same thing happens in Edge).

我不确定这是否还会在生产环境中发生，我们可能会在两个应用程序中使用相同的主机，所以这将是一个问题.如果这仅与本地主机相关，则可以，但我认为不是这种情况.

I'm not really sure if this could also happen in production, we'll probably use the same host for both apps, so that would be a problem. If this is something related only to localhost, then it's ok, but I don't think that's the case.

有什么想法在这里发生吗?

Any idea of what could be happening here?

谢谢.

推荐答案

我有一个类似的问题，我认为原因是两个实例在浏览器中将使用相同的会话cookie".

I had a similar problem, and I think the cause is that both instances would use the same "session cookie" in the browser.

为我修复的解决方案是重命名默认为session的SESSION_COOKIE_NAME.

The solution that fixed it for me was renaming the SESSION_COOKIE_NAME which is session by default.

app.config.update(SESSION_COOKIE_NAME=<new_session_name>)
