如何在浏览器上运行棘轮的shell脚本，同时在cmd上运行talnet

Telnet localhost 8080工作正常，但之后当我在localhost上创建shell脚本时，它在firefox和chrome中显示错误，请参阅下面的

Firefox can't establish a connection to the server at ws://localhost:8080/. var conn = new WebSocket('ws://localhost:8080');

这是我的外壳脚本

   <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
   </script>
   <script>
   jQuery(document).ready(function(){
     var conn = new WebSocket('ws://localhost:8080');
    conn.onopen = function(e) {
     console.log("Connection established!");
    };
   conn.onmessage = function(e) {
    console.log(e.data);
     };
     });
   </script>

这是我的chat-server.php代码'

   require dirname(__DIR__) . '/vendor/autoload.php';
   $server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Chat()
        )
    ),
    8080
    );
   $server->run();'

shell脚本保存在根目录的info.php中，chat-server.php保存在root/bin/目录中，但总是显示相同的错误，我不知道如何在localhost.please help上运行棘轮shell脚本！
