Infinitely listen to jabber events? - ruby-on-rails

Question

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.
I want to get callbacks from the server without browser refreshes. I tried to use ActionController::Live for this.
In my client side, my code is:
var source = new EventSource('/chat/events');
source.addEventListener('refresh', function(event)
{
AddMessage(event.data);
});
My controller code is:
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
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
What I got:
The chat_events method of the controller is called every second or so.
Because of this, several callbacks are executed at once.
When I got a message, I got it four or five times.
{"message":"fffdsfd"}
{"message":"fffdsfd"}
{"message":"fffdsfd"}
{"message":"fffdsfd"}
And the worst stuff - my server is not responding to other responses, although I use the Puma multi-threaded server.
What is the correct way to implement functionality like this?

Answer 1

I get the solution
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
