如何通过会话 ID 找到设备用户? [英] How can I find a devise user by it's session id?

问题描述

给定session["session_id"] 是否可以找到该会话所属的登录User?

Given session["session_id"] is it possible to find the logged in User to which that session belongs to?

推荐答案

至少在我的系统上(rails 3.2，devise 2.0.4)，你可以这样做:

At least on my system (rails 3.2, devise 2.0.4), you can do it like this:

session 是:

{"session_id"=>"be02f27d504672bab3408a0ccf5c1db5", "_csrf_token"=>"DKaCNX3/DMloaCHbVSNq33NJjYIg51X0z/p2T1VRzfY=", "warden.user.user.key"=>["User", [3], "$2a$10$5HFWNuz5p6fT3Z4ZvJfQq."]}

session["warden.user.user.key"][1][0]，然后是3.

所以，我认为它是:

User.find(session["warden.user.user.key"][1][0])
