javascript - Ratchet Websocket Apache2 SSL 无法连接到 PHP websocket

Question

一直在研究 Ratchet over SSL 的问题，并一直试图通过启用 proxy.load 和 proxy_wstunnel.load mods 来让我的 Apache2 服务器配置工作。

/etc/apache2/mods-enabled:
     proxy.conf -> ../mods-available/proxy.conf
     proxy.load -> ../mods-available/proxy.load
     proxy_wstunnel.load -> ../mods-available/proxy_wstunnel.load

我在 apache2.conf 的末尾添加了以下行:
ProxyPass /wss2/ ws://domain.com:8080
PHP socket-server.php 文件:

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use Websocket\SocketControl;
use Ratchet\Session\SessionProvider;
use Symfony\Component\HttpFoundation\Session\Storage\Handler;

    require dirname(__DIR__) . '/vendor/autoload.php';

    $memcache = new Memcache;
    $memcache->connect('localhost', 11211);

    $session = new SessionProvider(
        new SocketControl,
        new Handler\MemcacheSessionHandler($memcache)
    );

    $server = IoServer::factory(
        new HttpServer(
            new WsServer(
                $session
            )
        ),
        8080
    );

    $server->run();

尝试连接socket服务器的相关JS代码:

var websocket = {
    wsUri:"wss://domain.com/wss2/NNN",
    socket:null,
    cryptKey:null,
    init:function(){
        try {
            if (typeof MozWebSocket == "function")
                WebSocket = MozWebSocket;
            if ( websocket.socket && websocket.socket.readyState == 1 )
                websocket.socket.close();

            websocket.socket = new WebSocket( websocket.wsUri );
            websocket.socket.onopen = websocket.onopen.bind();
            websocket.socket.onclose = websocket.onclose.bind();
            websocket.socket.onmessage = websocket.onmessage.bind();
            websocket.socket.onerror = websocket.onerror.bind();

        } catch (exception) {
            console.log("ERROR: " + exception);
        }
    },

尝试连接时收到的错误:
WebSocket connection to 'wss://domain.com/wss2/NNN' failed: Error during WebSocket handshake: Unexpected response code: 502

我想我发布这个帖子晚了，但我在这里也有一个带有路由的工作示例。根据最新的 Ratchet 版本，代码运行良好。

<?php
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
require __DIR__ . '/vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use Psr\Http\Message\RequestInterface;
use Ratchet\Http\Router;
use Ratchet\Http\HttpServerInterface;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\HttpFoundation\Request;

$routes = new RouteCollection;
$loop = React\EventLoop\Factory::create();

$decorated = new WsServer(new ChatRoom);
$decorated->enableKeepAlive($loop);
$routes->add('chat-room', new Route('/chat-room', array('_controller' => $decorated), array('Origin' => $GLOBALS['Address']), 
    array(), $GLOBALS['Address'], array(), array('GET')));

$decorated = new WsServer(new SingleChat);
$decorated->enableKeepAlive($loop);
$routes->add('single-chat', new Route('/single-chat', array('_controller' => $decorated), array('Origin' => $GLOBALS['Address']), 
    array(), $GLOBALS['Address'], array(), array('GET')));

$decorated = new WsServer(new Ratchet\Server\EchoServer);
$decorated->enableKeepAlive($loop);
$routes->add('echo', new Route('/echo', array('_controller' => $decorated), array('Origin' => $GLOBALS['Address']), 
    array(), $GLOBALS['Address'], array(), array('GET')));


$app = new HttpServer(new Router(new UrlMatcher($routes, new RequestContext)));

$secure_websockets = new \React\Socket\Server('0.0.0.0:8091', $loop);
$secure_websockets = new \React\Socket\SecureServer($secure_websockets, $loop, [
    'local_cert' => 'path/to/certificate.crt',
    'local_pk' => '/path/to/your-key.key',
    'verify_peer' => false
]);

$secure_websockets_server = new \Ratchet\Server\IoServer($app, $secure_websockets, $loop);
$secure_websockets_server->run();
