Ruby on Rails：如何在服务器端从Redis获取所有会话数据？

Question

I need to get all active sessions' data from my Rails application. I am using Redis for session store.

I tried REDIS.keys and then REDIS.get("SESSION_KEY") but it seems like encrypted data .

Is there any painless solution to get live sessions' data on Rails?

Thanks.

Answer 1

Decrypt the Rails session data from Redis

Ruby on Rails using Marshal method for saving objects to cache. For example:
https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/http/rack_cache.rb#L17

You can unmarshalling this data as follows:

Marshal.load(REDIS.get("SESSION_KEY"))
