WebSocketBundle | Websocket server for Symfony applications | Websocket library

I'm building an application where I can see realtime changes within the logs This application is build with the Symfony v4.1. There is this bundle that has a Web Socket server and client based on Ratchet and Autobahn.js

I've setup all the requirements to make it work according to the documentation.

• There's a Topic class:

• pubsub routing is configured

• The server runs

• Client runs in javascript when page is loaded

The script to connect works fine, until I subscribe to a channel/topic. The connection is immediately closed on the client side, without the server detecting it. Does anyone know how to solve this? Also, I'm curious what this responsecode WS-1007 means.

Javascript:

I have enabled the PDO Periodic Pings for GOS:WebSocketBundle, I'm still getting this error from time to time:

Quite fascinating fact I just found out while messing up with WebSocket application I am now building using Symfony 4.1 and https://github.com/GeniusesOfSymfony/WebSocketBundle (which is built upon PHP Ratchet).

I wanted to fetch the newest data periodically from the MySQL database for testing purpose using $repository->find(2); but it always returned the same result even though I was changing data while being subscribed to the WebSocket channel.

After quite a lot of hours of messing with the code and crying, I found out that for some reason Doctrine is caching results (or that is what I think it does).

To test my theory, I created a service that handles fetching from the database with the following code:

Context

I am new to websockets, and trying to implement a notifications pusher on Symfony with the help of the WebsocketBundle, following this tutorial.

The bundle is implementing 3 different pushers :

• I tried using the zmq pusher and it just does not seem to fit with Windows (I am getting the exact same symptoms as in the linked post)

• I then tried WebSocketPusher and when I run the WSServer the port I configured in config.yml is not even opening. Same symptom as this open issue

• So, finally, I tried to use AMQP pusher and this time I cannot even install it, but as my google searches do not end up in github open issues, I think that I'm probably the one missing something here, and thus I'm posting here.

Problem

I installed the php extension and it does seem to work as it appears in my php extensions and does not give any errors.

When I run the following command from the tutorial : composer require gos/react-amqp I am getting the following response :

using GeniusesOfSymfony/WebSocketBundle with

I'm implementing sockets on my app, so I did these steps:

1. Create the topic handler service, like this but with an Entity Manager on his __construct method.

   ...

I'm using Dropwizard for a REST server and dropwizard-websocket-jee7-bundle to enable websockets.
For the websocket server I used this example.
Testing the websocket server standalone works fine, but in combination with Dropwizard, when a client tries to connect (to ws://localhost:port/actions) it gets a 500 Internal Server Error (Error log below).
I'm guessing there is some bad or missing configuration, but I can't figure our where.

ServerExample:

I used this plugin GeniusesOfSymfony/WebSocketBundle to integrate websockets in my application.

However through the documentation I didn't find how to push data into the channel once we've subscribed to it, from outide the "socket/connect" event:

I'm working on a Symfony2 application with WebSocketBundle.
https://github.com/GeniusesOfSymfony/WebSocketBundle.
The installation of the bundle has been done successfully.
So, I run a websocket server (port 8080 in local) with simple command : "php app/console gos:websocket:server" while my symfony server is running (port 8000 in local).

I setup a simple client javascript to use WebSocketBundle following official tutorial which is on the github of the bundle.

When I come to a page on my website, I am correctly connected to the websocket server.
The problem comes when I want to use functions subscribe() and publish() that allow a user to subscribe to a channel, when anybody publish something on this channel, the message is received by the subscriber.

In my case, the message is not sent or received, I don't really know why because no revelant error is shown, I tried to follow as accurately as possible the official tutorial here :
https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/TopicSetup.md
But, unfortunately, I can't manage to make this works. That's why I solicit you to help me.

I share you below the most revelant piece of code to show how the setup takes place :
