到“ws://localhost:8001/”的 WebSocket 连接失败：

问题描述

这是一个服务器脚本，用于初始化 Web 套接字服务器并侦听与 8001 端口的客户端连接。我的网站是关于投标的。因此，当有人点击出价按钮时，我想这样做，该特定用户详细信息（用户名和头像）将显示给所有其他出价者。所以这就是我使用带有 PHP Laravel 的网络套接字的原因，它在 localhost 上工作正常，但在实时服务器上出现错误。下面附上错误图片。

composer.json

{
    "autoload": {
        "psr-4": {
            "MyApp\\": "src"
        }
    },"require": {
        "cboden/ratchet": "^0.4"
    }
}

消息组件接口

namespace MyApp;

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 to send messages to later
        $this->clients->attach($conn);
        echo "New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from,$msg)
    {
        $numRecv = count($this->clients) - 1;
        echo sprintf('Connection %d sending message "%s" to %d other connection%s' . "\n",$from->resourceId,$msg,$numRecv,$numRecv == 1 ? '' : 's');

        foreach ($this->clients as $client) {
            if ($from !== $client) {
                // The sender is not the receiver,send to each client connected
                $client->send($msg);
            }
        }
    }

    public function onClose(ConnectionInterface $conn)
    {
        // The connection is closed,remove it,as we can no longer send it messages
        $this->clients->detach($conn);
        echo "Connection {$conn->resourceId} has disconnected\n";
    }

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

另一个 PHP 文件

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;

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

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

$server->run();
