I'm trying to run the demo on Docker (Windows) with php7.2 but I can't get past this issue. Maybe I'm missing something simple, I'd appreciate your input.

I just did the following:

1. Clone the repository
2. cd WebSocketAppDemo
3. composer install
4. symfony server:start, it's running on port 8000
5. Open a new tab of my terminal
6. php bin/console gos:websocket:server
7. Open Safari, go to https://127.0.0.1:8000

I get the following error:

It seems the variables required in the homepage template (line 12) are not set in Symfony. Did I do something wrong?

I set up a websockets server locally running via wss and I can connect to it successfully:

websocket.on("socket/connect", function(session){
        console.log('connected');
}

works as expected.

However, once I try

session.subscribe("chat", function(uri, payload){
    console.log("Received message", payload.msg);
 });

I am immediately disconnected. In Firefox the message is "Disconnected: Connection lost - scheduled 1th reconnect to occur in 5 second(s). With code 6"

From the server side the log display as follows:

17:36:15 DEBUG     [websocket] INSERT CLIENT 897 ["user" => "s:36:"anon-8148039825a8aeeef50fab594866255";"] []
17:36:15 INFO      [websocket] anon-8148039825a8aeeef50fab594866255 connected ["connection_id" => 897,"session_id" => "8148039825a8aeeef50fab594866255","storage_id" => 897] []
17:36:15 DEBUG     [websocket] GET CLIENT 897 [] []
17:36:15 INFO      [websocket] anon-8148039825a8aeeef50fab594866255 subscribe to chat [] []
17:36:20 DEBUG     [websocket] INSERT CLIENT 894 ["user" => "s:37:"anon-12065318285a8aeeea4b641205203743";"] []

I added the respective topic with a name "chat" and registered it as a service with the correct tag.

Is there something I am missing here? Could it be that this problem is related to usage via SSL?

I have setup websocket in my project and follow Installation Instructions as you mention.
your demo is working nice but, when i tried to implement it on my project, I'm getting

rpc handler acme.rpc not exists, only [ ] are available
error.

I'm attaching code which i did.
config.yml
gos_web_socket: server: port: 8081 #The port the socket server will listen on host: 192.168.1.32 #The host ip to bind to router: resources: - '@SlideshowSocketBundle/Resources/config/pubsub/routing.yml'

pubsub_routing.yml
acme_rpc: channel: api/{method} handler: callback: 'acme.rpc' #related to the getName() or your RPC service requirements: method: pattern: "[a-z_]+"

AcmeRpc.php
`<?php
/**

  */

namespace Slideshow\SocketBundle\RPC;

use Ratchet\ConnectionInterface;
use Gos\Bundle\WebSocketBundle\RPC\RpcInterface;
use Gos\Bundle\WebSocketBundle\Router\WampRequest;

class AcmeRpc implements RpcInterface
{
/**
* Adds the params together
*
* Note: $conn isnt used here, but contains the connection of the person making this request.
*
* @param ConnectionInterface $connection
* @param WampRequest $request
* @param array $params
* @return int
*/
public function sum(ConnectionInterface $connection, WampRequest $request, $params)
{
return array("result" => array_sum($params));
}

/**
 * Name of RPC, use for pubsub router (see step3)
 *
 * @return string
 */
public function getName()
{
    return 'acme.rpc';
}

}`

It's just a reminder for all people who try to run this project with docker-compose. I got errors

• WebSocket connection to 'ws://127.0.0.1:1337/' failed: Connection closed before receiving a handshake response
• Disconnected for Connection could not be established. with code 3

Solution: you should specify HOST=0.0.0.0 instead of 127.0.0.1.

Here is a sample docker-compose file:

version: '3.2'

services:
    web:
        build: app/docker/php
        ports:
            - 9000:9000
            - 1337:1337
        volumes:
            - ./:/var/www/html
        environment:
            SYMFONY_ENV: dev
        entrypoint: app/docker/php/docker-entrypoint.sh
    nginx:
        image: nginx:latest
        ports:
            - 80:80
        environment:
            - NGINX_PORT=80
            - WWW_DIR=/var/www/html/public
        volumes:
            - ./app/docker/nginx:/etc/nginx/conf.d
            - ./:/var/www/html
            - ./var/logs/nginx:/var/log/nginx
        command: /bin/bash -c "exec nginx -g 'daemon off;'"

I could provide files that I have in "app/docker" folder if needed. Or could create a Pull request if you'd like.

Hi,

I'm unable to run the demo because this error:

[Symfony\Component\Debug\Exception\ContextErrorException]
  Catchable Fatal Error: Argument 1 passed to Ratchet\Wamp\TopicManager::__construct() must implement interface Ratchet\Wamp\WampServerInterface, none given, called in /WebsocketAppDemo/app/cache/dev/appDevDebugProjectContainer.php on line 2060 and defined

This I guess is because both cboden/ratchet and gos/ratchet libs are required as deps. The code seems wrote for gos/ratchet but the problem is that the two libs have the same namespace with different constructors.

Can you fix it?

Fatal error: Class 'Symfony\Component\Debug\Debug' not found in /WebsocketAppDemo/web/app_dev.php on line 21

Tried to install manually symfony/debug, no luck

Attempted to call an undefined method named "loadClassCache" of class "AppKernel".

Hello,

Your demo is nicely working on localhost.
But, When i move to live, it is not working. Getting the following error.

_An exception has been thrown during the compilation of a template ("Unable to find file "@GosWebSocketBundle/Resources/public/js/vendor/autobahn.min.js".") in "GosWebSocketBundle::client.html.twig".

Here is the screen shot of error page.
