当用户登录时，会为他创建一个 session ，但如果他转到另一台计算机并登录，则会为他的帐户创建第二个 session 。我想做到这一点，以便用户不能超过一个有效 session 。有没有办法通过user.steamId把session存在redis中，这样他的第一个session就失效了？

任何帮助都将非常感谢!

最佳答案

你能用这个吗:https://www.npmjs.com/package/redis-sessions ？

有一个名为 soid 的方法，它可以获取单个 ID 的所有 session 。您可以在用户登录时查询他们的 ID。然后从该 ID 获取所有 session 。如果 soid 返回空，您可以安全地假设用户没有 session 。如果它返回时里面有东西，那么用户就有了 session 。

这是我目前最好的尝试。

祝你好运。
