I have a Rails Application with websocket-rails gem.
Inside my application there is a Daemon that I launch with rails runner MyDaemon.start
I'm using websocket-rails Synchronization, so my config/initializers/websocket_rails.rb
looks like this:
WebsocketRails.setup do |config|
config.log_internal_events = false
config.standalone = false
config.synchronize = true
end
Inside MyDaemon
, using synchronization, I can trigger event that will reach both my WebsocketRails::BaseController
and my javascript WebSocketRails
.
What I'm trying to do is to find a way to bind to events from my MyDaemon
.
I've tried to implement a plain WebSocket client using both faye-websocket-ruby and websocket-client-simple, but after banging my head on my keyboard for some time, I figured out that there is some kind of "handshake" process using connection_id
from the client_connected
message. Basically none of the solutions provided in this other so question works for me.
I need to understand if inside my MyDaemon
I can subscribe directly to some WebsocketRails
callback, even inside an EventMachine, or how should I implement a Websocket Client in Ruby itself.
My last attempt to have a ruby client can be found in this gist, and this is a sample output:
ruby client.rb ws://localhost:3000/websocket
[:open, {"upgrade"=>"websocket", "connection"=>"Upgrade", "sec-websocket-accept"=>"zNTdGvxFKJeP+1PyGf27T4x2PGo="}]
JSON message is
[["client_connected", {"id"=>nil, "channel"=>nil, "user_id"=>nil, "data"=>{"connection_id"=>"4b7b91001befb160d17b"}, "success"=>nil, "result"=>nil, "token"=>nil, "server_token"=>nil}]]
client id is 4b7b91001befb160d17b
[:message, "[[\"client_connected\",{\"id\":null,\"channel\":null,\"user_id\":null,\"data\":{\"connection_id\":\"4b7b91001befb160d17b\"},\"success\":null,\"result\":null,\"token\":null,\"server_token\":null}]]"]
JSON message is
[["websocket_rails.ping", {"id"=>nil, "channel"=>nil, "user_id"=>nil, "data"=>{}, "success"=>nil, "result"=>nil, "token"=>nil, "server_token"=>nil}]]
Sending ["pong",{}]
[:message, "[[\"websocket_rails.ping\",{\"id\":null,\"channel\":null,\"user_id\":null,\"data\":{},\"success\":null,\"result\":null,\"token\":null,\"server_token\":null}]]"]
[:close, 1006, ""]
While the log of websocket-rails
is:

Probably I'm missing somethig very stupid, so I'm here to ask your help!
