无限监听 jabber 事件?

问题描述

我正在 Ruby on Rails 上使用 Jabber 编写聊天应用程序.发送消息很容易实现，但循环接收消息是一个很大的挑战.

I am writing a chat application, using Jabber, on Ruby on Rails. Sending messages was quite easy to implement, but receiving messages in a loop is quite a challenge.

我想在不刷新浏览器的情况下从服务器获取回调.为此，我尝试使用 ActionController::Live.

I want to get callbacks from the server without browser refreshes. I tried to use ActionController::Live for this.

在我的客户端，我的代码是:

In my client side, my code is:

var source = new EventSource('/chat/events');
source.addEventListener('refresh', function(event)
{
AddMessage(event.data);
});

我的控制器代码是:

def chat_events
  # SSE expects the `text/event-stream` content type
  response.headers['Content-Type'] = 'text/event-stream'
  sse = Reloader::SSE.new(response.stream)

puts "Starting XMMP call"
 begin
  @xmmpClient = XmppClient.new
  @xmmpClient.loginUsingNameAndPassword(****, ***)
  @xmmpClient.listen_connections sse
 rescue IOError
  puts "Error"
  # When the client disconnects, we'll get an IOError on write
 ensure
  puts "closing stream"
  sse.close
 end
end

而且，我的 XMMP 客户端是:

And, my XMMP client is:

def listen_connections(writer = nil)
 if not @logged_in
    puts "Not logged"
    raise "Not logged"
 end
 @robot.send(Jabber::Presence.new.set_show(nil))
 loop do
  puts "Listening callback"
  @robot.add_message_callback do |message|
    puts "Got message " + message.inspect
    if not writer.nil?
      writer.write({ :message => message.body }, :event => 'refresh')
    end
  end
  sleep 2
end
end

我得到了什么:

1. 控制器的 chat_events 方法大约每秒调用一次.
2. 因此，一次执行多个回调.

3. 当我收到一条消息时，我收到了四五次.

1. The chat_events method of the controller is called every second or so.
2. Because of this, several callbacks are executed at once.

3. When I got a message, I got it four or five times.

{"message":"fffdsfd"}
{"message":"fffdsfd"}
{"message":"fffdsfd"}
{"message":"fffdsfd"}

最糟糕的是 - 我的服务器没有响应其他响应，尽管我使用 Puma 多线程服务器.

And the worst stuff - my server is not responding to other responses, although I use the Puma multi-threaded server.

实现此类功能的正确方法是什么?

What is the correct way to implement functionality like this?

推荐答案

我得到解决方案

  puts "."
  client.add_message_callback do |message|
    if message.type != :error
        arr = message.from.to_s.split('@')
        puts arr[0]
        puts message.body

    end
  end

 while 1
 end
