Question

我正在使用棘轮系统尝试为应用设置Websocket服务器。每次出现此错误时，我的连接都出现问题：

与'ws：//：8080'的WebSocket连接失败：在执行期间出错 WebSocket握手：意外的响应代码：403

这是共享主机的文件夹中托管的代码。我将脚本命名为index.php

是否可以解决此问题？也许我需要检查我的php脚本？

<?php
 require __DIR__.'/vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Chat implements MessageComponentInterface {

protected $clients;

public function __construct() {
    $this->clients = new \SplObjectStorage;
}

public function onOpen(ConnectionInterface $conn) {
    //store the new connection
    $this->clients->attach($conn);

    echo "someone connected\n";
}

public function onMessage(ConnectionInterface $from, $msg) {
    //send the message to all the other clients except the one who sent.
    foreach ($this->clients as $client) {
        if ($from !== $client) {
            $client->send($msg);
        }
    }
}

public function onClose(ConnectionInterface $conn) {
    $this->clients->detach($conn);
    echo "someone has disconnected";
}

public function onError(ConnectionInterface $conn, \Exception $e) {
    echo "An error has occurred: {$e->getMessage()}\n";
    $conn->close();
}


}

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

$server->run();
