REDIS中密钥过期时如何获取回调 [英] How to get callback when key expires in REDIS

问题描述

我正在使用Bottle开发应用程序.在我的注册表中，我要通过邮件确认带有唯一密钥的电子邮件.我将此密钥存储在REDIS中，有效期为4天.如果用户未在4天内确认电子邮件，则密钥将过期.为此，我想从数据库(mongoDB)中永久删除用户条目.

I'm developing application using Bottle. In my registration form, I'm confirming email by mail with a unique key. I'm storing this key in REDIS with expiry of 4 days. If user does not confirm email within 4 days, key gets expired. for this, I want to permanently delete the user entry from my database(mongoDB).

当然，我不需要对我的Redis服务器进行连续轮询来检查密钥是否存在.

Ofcourse I dont require continous polling to my redis server to check whether key exists or not.

有什么方法可以从Redis中获取回调吗?

Is there any way to get a callback from Redis??

或者还有其他有效的方法吗?
