Finding the session id in rails 3

Question

How can I get the current session id in rails 3?

I've tried the following with no luck:

session[:session_id]
session['session_id']
session[:id]
session['id']
session.id
session.session_id

Answer 1

您是否尝试过以下方法？

request.session_options[:id]

Answer 2

它还返回会话 ID：

session[:session_id]

Answer 3

If you need to see data written in Session store for given session id from Rails console you can:

a = Rails.application.config.session_store.new(app, Rails.application.config.session_options)
a.class # => ActionDispatch::Session::RedisStore
a.get_session(ENV, '07319b2485be9ac4850664cd47cede38')


# or a.find_session(ENV, '07319b2485be9ac4850664cd47cede38')

app and ENV are set when you start rails console, don't need to set those

you can get the session_id via some a browser plugin dealing with cookies or (cookie inspector, cookies manager, ...)

Answer 4

I can't test it right now but as far as I know the session id variable changed from 'id' to 'session_id' on Rails 3, have you tried that one? Hope it works for you.

Answer 5

Rails 4.0以后应该是：

session.id
