application and actioncable won't share cookie

[bassie97]

I am using devise for authentication, but when I implemented your method I got "An unauthorized connection attempt was rejected"

After hours of searching I found out that:

   cookies.signed['user.id']

returns nil. In the following code block.

    def find_verified_user
      if verified_user = User.find_by(id: cookies.signed['user.id'])
        verified_user
      else
        reject_unauthorized_connection
      end
    end

I checked and there is definitely a cookie but it does not contain the cookie data set by Devise.

To check if the 'user.id' actually is set I raise it in the view. This, as excepted, return the user id

Signed in as @#{cookies.signed[:username]}.
- raise(cookies.signed['user.id'].inspect)
%br/
%br/
#messages
%br/
%br/
= form_for :message, url: messages_path, remote: true, id: 'messages-form' do |f|
  = f.label :body, 'Enter a message:'
  %br/
  = f.text_field :body
  %br/
  = f.submit 'Send message'

My question/issue: It seems like the cookie is not available at the actioncable server. Is there a way to share the cookie set by Devise with the cable server?

Hi, the devise cookie should be available but the plumbing required to make it available in cookies.signed is not done by actioncable automatically. I haven't tried this, but http://www.rubytutorial.io/actioncable-devise-authentication/ might be a solution for your issue.
Sorry for the late reply.

What about in the case where you have an SSO situation? For example, you have an SSO auth server which is running ActionCable, and a suite of children apps that point their ActionCable to the location of the SSO ActionCable endpoint? I've been trying this lately to add a warden hook to share the cookies, changing session_store.rb to add domain: 'lvh.me', tld_length: 2. I notice if I do a binding.pry in the controller for the SSO app and a binding.pry in the dashboard controller for the child app that the cookies are set indeed, but ActionCable still doesn't pick it up. Any ideas?
