我尝试创建与有线服务器的连接并订阅频道，但出现日志错误：
Started GET "/cable" for 172.20.0.1 at 2017-05-27 08:29:39 +0000
Started GET "/cable/" [WebSocket] for 172.20.0.1 at 2017-05-27 08:29:39 +0000
Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: upgrade, HTTP_UPGRADE: websocket)
WebSocket error occurred: wrong number of arguments (given 2, expected 1)
我的代码：
// order_slots.coffee
jQuery(document).ready ->
//some jquery code that call create_channel function
create_channel = (order_id) ->
App.cable.subscriptions.create {
channel: "OrderSlotsChannel",
order_id: order_id
},
connected: ->
# Called when the subscription is ready for use on the server
disconnected: ->
# Called when the subscription has been terminated by the server
received: (data) ->
# Data received
具体渠道：
//order_slots_channel
class OrderSlotsChannel < ApplicationCable::Channel
def subscribed
stream_from "order_slots_#{params[:order_id]}_channel"
end
def unsubscribed; end
end
和 ActionCable 连接：
# Be sure to restart your server when you modify this file. Action Cable runs in a loop that does not support auto reloading.
module ApplicationCable
class Connection < ActionCable::Connection::Base
identified_by :current_user
def connect
self.current_user = find_verified_user
logger.add_tags 'ActionCable', current_user.email
end
protected
def find_verified_user
verified_user = env['warden'].user
verified_user || reject_unauthorized_connection
end
end
end
ActionCable::Channel::Base - 只是空的。我将不胜感激任何帮助。提前致谢
我解决了这个问题。该项目使用Passenger Phusion 作为应用服务器，5.0.x 版本与rails 5.1 和action cable 的结合不好。您应该将乘客更新到 5.1.x
