ActionCable.server =>‘/cable’仅限于authenticated_rooth_path

Question

考虑以下情况：

1) WebSocket验证连接.

def connect
  self.current_user = find_verified_user
  logger.add_tags "ActionCable", "User #{current_user.id}"
end

( 2)当建立连接时，通知用户

  connected: ->
    $("body").append("<div class='connection ok'>Connected.</div>")

3)当连接丢失时，通知用户

  disconnected: ->
    $("pop-up").append("<div class='connection'>Offline, trying to reconnect...</div>")

4)当用户注销时.

An unauthorized connection attempt was rejected
###User is now informed connection is lost. Which should not happen.

我的问题：如何更改：

  mount ActionCable.server => '/cable'

若要仅在的范围内运行，请执行以下操作：

 authenticated :user do
   root 'users#index', as: :authenticated_root
 end

替代解

未经授权的连接尝试被拒绝。

...happens，当reject_unauthorized_connection在connection.rb中被调用时。

• 这可能是故意的或而不是

- remove `reject_unauthorized_connection` if you want to allow non-signed-users to subscribe to the channel: `current_user` becomes `nil`

    - To be able to still identify the user, you can add another identifier (`:session_id`) : 

模块ApplicationCable类连接< ActionCable:: Connection ::Base identified_by :current_user identified_by :session_id def self.current_user = find_verified_user self.session_id = request.session.id end私有def find_verified_user User.find_by(id: cookies.signed:user_id) end #.

-如果您需要客人和登录用户之间的进一步授权规则，您可能希望在您的*_channel.rb中而不是在connection.rb中写入您自己的授权。

​

- retain `reject_unauthorized_connection` if you only want signed-in users to be able to subscribe to your channels.
