Question

刚开始使用棘轮。当我第一次测试它时，它可以正常使用websockets，获得请求等。但是现在我和我一样做了，但是请求（onOpen）甚至没有得到请求，我得到了这个JS错误：

WebSocket connection to 'ws://localhost:8080/' failed: Error during WebSocket handshake: Unexpected response code: 404

jscode：

var conn = new WebSocket("ws://localhost:8080");
conn.onopen = function(e) {
    console.log("Connected!");
    conn.send("hello server");
};
conn.onmessage = function (e) {
    console.log(e.data);
};

我的源代码：

主档案：

require __DIR__ . "../../library/loader.php";
require __DIR__ . "../../vendor/autoload.php";

error_reporting(E_ALL);

use Ratchet\WebSocket\WsServer,
    Ratchet\Http\HttpServer,
    Ratchet\Server\IoServer;

use bin\library\AsynChatServer;

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

$server->run();

服务器类：

namespace bin\library;

use Ratchet\MessageComponentInterface,
    Ratchet\ConnectionInterface,
    Ratchet\Server\IoConnection;

use bin\library\database\Db;

use bin\library\model\Client,
    bin\library\model\PacketManager;

class AsynChatServer implements MessageComponentInterface {

    private $clients;

    /** @var Db */
    private $database;

    /** @var PacketManager */

    private $packets;

    function __construct()
    {
        $this->clients = array();
        $this->database = new Db();
        $this->packets = new PacketManager($this);

        AsynChatServer::println("Server has started up.");
    }

    /**

     * @param  ConnectionInterface $conn The socket/connection that just connected to your application
     * @throws \Exception
     */

    function onOpen(ConnectionInterface $conn)
    {
        echo "request";
        /** @var $client Client */
        $client = new Client($conn);
        $this->clients[$conn->resourceId] = $client;
        AsynChatServer::println("New client accepted: " + $client->getClient()->getRemoteAddress());
    }

    /**
     * This is called before or after a socket is closed (depends on how it's closed).  SendMessage to $conn will not result in an error if it has already been closed.
     * @param  ConnectionInterface $conn The socket/connection that is closing/closed
     * @throws \Exception
     */
    function onClose(ConnectionInterface $conn)
    {
        // TODO: Implement onClose() method.
    }

    /**

     * the Exception is sent back down the stack, handled by the Server and bubbled back up the application through this method

     * @param  \Exception $e
     * @throws \Exception
     */
    function onError(ConnectionInterface $conn, \Exception $e)
    {
        // TODO: Implement onError() method.
    }

    /**
     * Triggered when a client sends data through the socket
     * @param  \Ratchet\ConnectionInterface $from The socket/connection that sent the message to your application
     * @param  string $msg  The message received
     * @throws \Exception
     */

    function onMessage(ConnectionInterface $from, $msg)
    {
        /** @var $client Client */
        $client = $this->clients[$from->resourceId];
        AsynChatServer::println("Paccket received from: " . $client->getClient()->getRemoteAddress());
        $this->packets->processPacket($client, $msg);
    }

    public static function println($message) {
        echo $message . "\n";
    }

    public function getDB() {
        return $this->database;
    }

}

有什么问题吗？库可能已损坏，所以我需要重新设置它吗？这是我跑步时得到的输出：

c:\xampp1\php>php c:/xampp1/htdocs/AsynChat/bin/AsynChat.php
Server has started up.

连接时没有别的，没有信号错误。

有什么问题？

NETSTAT -A：

  TCP    127.0.0.1:8080         Ben-╧╩:0               LISTENING
  TCP    127.0.0.1:8080         Ben-╧╩:0               LISTENING

我的App.php构造函数：

public function __construct($httpHost = 'localhost', $port = 8080, $address = '127.0.0.1', LoopInterface $loop = null) {
