PHP中的Websocket和Apache上的Ratchet

如何解决PHP中的Websocket和Apache上的Ratchet

我是WebSockets的新手，我有一个运行Apache的PHP host 主机，并在Websocket中使用了Ratchet库。当我尝试连接时，我无法连接到错误。

这是JS代码：

const conn = new WebSocket('wss://example.com/test/test.php');
console.log(conn);

conn.onopen = function () {
    console.log('Connected');
    conn.send(JSON.stringify({ message: 'hello' }));
}

conn.onmessage = function (e) {
    console.log(`New Message ${e.data}`);
}

conn.onclose = function () {
    console.log('Connection Closed');
}

以及JS连接的PHP代码：

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;

require_once $_SERVER['DOCUMENT_ROOT'] . "/lib/vendor/autoload.php";
require_once $_SERVER['DOCUMENT_ROOT'] . "/src/classes/Socket.php";


$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Socket()
        )
    ),8888
);

$server->run();

如果需要Socket（）类，请参见以下代码：

<?php

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Socket implements MessageComponentInterface
{
    protected $connected_users;

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

    public function onCall(ConnectionInterface $conn,$id,$topic,array $params)
    {
        //
    }


    public function onOpen(ConnectionInterface $conn)
    {
        $this->clients->attach($conn);
        $conn->send(json_encode(array("status" => "success")));
    }

    public function onMessage(ConnectionInterface $from,$msg)
    {
        $msg = json_decode($msg);
        // do something with the $msg

    }

    public function onClose(ConnectionInterface $conn)
    {
        $this->clients->detach($conn);
    }

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

        $conn->close();
    }
}
