php - Ratchet - 如何阻止其他网站连接到我的 websocket 服务器？

Question

http://socketo.me/docs/origin中有页面谈论它，但完全不清楚如何实现它。

这是我当前的代码(来自 http://socketo.me/docs/push 的教程):

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

$loop   = React\EventLoop\Factory::create();
$pusher = new MyApp\Pusher;

// Listen for the web server to make a ZeroMQ push after an ajax request
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://127.0.0.1:5555'); // Binding to 127.0.0.1 means the only client that can connect is itself
$pull->on('message', array($pusher, 'onBlogEntry'));

// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server('0.0.0.0:8080', $loop); // Binding to 0.0.0.0 means remotes can connect
$webServer = new Ratchet\Server\IoServer(
    new Ratchet\Http\HttpServer(
        new Ratchet\WebSocket\WsServer(
            new Ratchet\Wamp\WampServer(
                $pusher
            )
        )
    ),
    $webSock
);

$loop->run();

按照 http://socketo.me/docs/origin 上的教程进行操作它说我应该添加变量 $checkedApp到类的构造函数HttpServer 。我检查了souce code此类，并且它仅使用 __constructor() 中的一个参数，正如你所看到的，我已经将一个值传递给这个构造函数，它是类 WsServer 的一个实例。 。还有类MyHttpApp不存在。

之后我在源代码中搜索了一下，发现文件 App.php 位于 https://github.com/ratchetphp/Ratchet/blob/master/src/Ratchet/App.php要实现 OriginChecker，我只需将变量 $webServer 的值更改为以下值:

$webServer = new Ratchet\Server\IoServer(
    new Ratchet\Http\HttpServer(
        new Ratchet\Http\OriginCheck(
            new Ratchet\WebSocket\WsServer(
                new Ratchet\Wamp\WampServer(
                    $pusher
                )
            ),
            array('mydomain.com') //this is the only domain that can connect to the websocket
        )
    ),
    $webSock
);
