ruby-on-rails - ActionCable 不传输消息

Question

我正在 rails 5 中实现 action cable，它在本地运行良好，但在暂存和生产中，在将消息发送到 action cable rails logger 之后。

[ActionCable] Broadcasting to chats_4: {:id=>"message_97", :message=>"88", :user=>"John", :time=>"15-May-17 06:38 am", :chatroom_id=>4, :file=>nil}

但它没有传输给订阅者，浏览器控制台报错

Firefox can’t establish a connection to the server at wss://demo.xyz.com/cable.
The connection to wss://demo.xyz.com/cable was interrupted while the page was loading.

我的环境配置如下。

 config.action_cable.url = "wss://demo.xyz.com/cable"
 config.action_cable.allowed_request_origins = ['https://demo.xyz.com', 'http://demo.xyz.com']

我在 passenger + nginx 中托管应用程序

location /cable {
          passenger_app_group_name xyz_websocket;
           passenger_force_max_concurrent_requests_per_process 0;
         }

我的 nginx 日志说

2017/05/15 06:43:30 [error] 13412#0: *675 open() "/home/test/apps/xyz/current/public/cable" failed (2: No such file or directory), client: 103.xix.204.xx, server: https://demo.xyz.com, request: "GET /cable HTTP/1.1", host: "demo.xyz.com"

帮我解决这个问题。

可以阅读有关设置的更多信息 here ，但我会确保您单独安装有线服务器 - 这听起来像是“Passenger 实际上坚持将其作为一个单独的进程运行”
