ruby-on-rails – 用于websocket-rails gem的Ruby websocket客户端

我正在开发一个rails网页,需要使用websocket功能与外部 ruby客户端进行通信.为了做到这一点,我在rails服务器中使用websocket-rails gem,定义client_connected client_disconnected事件以及从客户端接收消息的特定操作(new_messagE).

在客户端,我尝试使用不同的ruby宝石,如faye-websocket-ruby和websocket-client-simple,但是当我尝试发送消息时总是会出错.在服务器上,我找不到处理这些消息的方法.两个gems都有一个Send方法,只接受一个字符串(不能指定事件的名称)

我一直在使用的代码如下：

服务器端

应用程序/控制器/ chat_controller.rb

class ChatController < WebsockeTrails::BaseController
  def new_message
    puts ')'*40
  end

  def client_connected
    puts '-'*40
  end

  def client_disconnected
    puts '&'*40
  end
end

配置/ events.rb

WebsockeTrails::EventMap.describe do
  subscribe :client_connected,:to => ChatController,:with_method => :client_connected

  subscribe :message,:with_method => :new_message

  subscribe :client_disconnected,:with_method => :client_disconnected
end

配置/初始化/ websocket_rails.rb

WebsockeTrails.setup do |config|
  config.log_path = "#{Rails.root}/log/websocket_rails.log"
  config.log_internal_events = true
  config.synchronize = false
end

客户端

WebSocket的客户端,简单

require 'rubygems'
require 'websocket-client-simple'

ws = WebSocket::Client::Simple.connect 'ws://localhost:3000/websocket'

ws.on :message do |msg|
  puts msg.data
end

ws.on :new_message do
  hash = { chAnnel: 'example' }
  ws.send hash
end

ws.on :close do |e|
  p e
  exit 1
end

ws.on :error do |e|
  p e
end

hash = { chAnnel: 'Example',message: 'Example' }
ws.send 'new_message',hash

loop do
  ws.send STDIN.gets.Strip
end

王菲-的WebSocket

require 'faye/websocket'
require 'eventmachine'

Em.run {
  ws = Faye::WebSocket::Client.new('ws://localhost:3000/websocket')

  ws.on :open do |event|
    p [:open]
  end

  ws.on :message do |event|
    p [:message,event.data]
  end

  ws.on :close do |event|
    p [:close,event.code,event.reason]
    ws = nil
  end

  ws.send( 'Example Text' )
}

提前致谢.问候.
