php - 如何使用 Thruway 在服务器端解析消息

Question

我想将 websocket 用于投票应用程序。有两个部分:一个是聊天 channel ，另一个是命令 channel ，其中有关问题、可用答案、倒计时等的信息将传播。

在客户端，我使用 Autobahn|JS作为图书馆。我可以轻松订阅我的两个 channel (我可以在服务器日志上看到)

在服务器端，我使用 Thruway因为它符合 WAMP v2。

我的问题:我不知道如何在服务器端 Hook 消息以在每个主题上广播它们。看起来很简单，但我可以找到任何解决方案。

我猜是通过使用 InternalClient，但我不太确定……

一些代码:

JS客户端

var ws;

var connection = new autobahn.Connection({
    url: 'ws://dev.test.com:8080/',
    realm: 'com.test.dev'
});

connection.onopen = function (session) {
    ws = session;

    function onevent(args) {
        console.log("Event:", args[0]);
    }

    session.subscribe('chat.test', onevent);
    session.subscribe('cmd.test', onevent);
};

connection.open();

紧接着，我在聊天框上添加了一个监听器:

$('#message').on('keydown', function(event) {
    var keycode = event.keyCode || event.which;

    if(keycode == '13') {
        event.preventDefault();

        ws.publish('chat.test', [{token: token, message: $('#message').val()}]);
        $('#message').val('');
    }
});

PHP服务器

<?php

require 'vendor/autoload.php';

use Thruway\Peer\Router;
use Thruway\Transport\RatchetTransportProvider;

class TestInternalClient extends Thruway\Peer\Client {

    public function __construct() {
        parent::__construct('com.test.dev');
    }

    public function onSessionStart($session, $transport) {
        echo "--------------- Hello from InternalClient ------------\n";

        $session->subscribe('chat.test', [$this, 'chat']);
    }

    public function chat($args, $kwArgs, $options) {
        // Decode chat message here? How to broadcast them?
    }

}

$router = new Router();
$router->addTransportProvider(new RatchetTransportProvider("0.0.0.0", 8080));
$router->addInternalClient(new TestInternalClient());
$router->start();

class TestInternalClient extends Thruway\Peer\Client {

    public function __construct() {
        parent::__construct('com.test.dev');
    }

    public function onSessionStart($session, $transport) {
        echo "--------------- Hello from InternalClient ------------\n";

        $session->subscribe('chat.test', function ($args, $kwArgs, $options) use ($session) {
            // Get message contents
            $token = $args[0]->token;
            $message = $args[0]->message;

            // publish to other people
            $session->publish('some.topic', [[ 'message' => $message ]]);
        });

        //////////////////////////////////////////
        // Subscribe to everything in the system
        $session->subscribe('', function ($args, $argsKw, $details, $publicationId) {
