无法使用 fsockopen 连接到 WebSocket 服务器

Can't connect to WebSocket server with fsockopen

请帮助我将 WebSocket 连接到 php。

我尝试了这个代码,但是我收到了 400 Bad Request

$fp = fsockopen("cs.money", 443, $errno, $errstr, 30);

if (!$fp) 
{
    echo "$errstr ($errno)<br />n";
} 
else
{
    $out = "GET / HTTP/1.1rnrn";
    ///Send data
    fwrite($fp, $out);

    ///Receive data - in small chunks :)
    while (!feof($fp)) 
    {
        echo fgets($fp, 128);
    }

    fclose($fp);
}

我用js解决了我的问题

var WebSocket = require('ws');
var ws = new WebSocket('wss://cs.money/ws');
