Question

我正在用php构建一个简单的聊天工具，而websocket是聊天应用程序的最佳方法之一

我完全是websocket的初学者，我为websocket连接编写了一个简单的代码，但出现了错误

WebSocket connection to 'ws://localhost:8080/htdocs/chat.php' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

这是我到目前为止编写的完整代码

<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script>
function showMessage(messageHTML) {
        $('#chat-box').append(messageHTML);
    }

    $(document).ready(function(){

        var websocket = new WebSocket("ws://localhost:8080/htdocs/chat.php"); 
        websocket.onopen = function(event) { 
            showMessage("<div class='chat-connection-ack'>Connection is established!</div>");       
        }
        websocket.onmessage = function(event) {
            var Data = JSON.parse(event.data);
            showMessage("<div class='"+Data.message_type+"'>"+Data.message+"</div>");
            $('#chat-message').val('');
        };

        websocket.onerror = function(event){
            showMessage("<div class='error'>Problem due to some Error</div>");
            console.log(event.data);
        };
        websocket.onclose = function(event){
            showMessage("<div class='chat-connection-ack'>Connection Closed</div>");
        }; 
    });
</script>
</head>
<body>

<div id="chat-box">
</div>

</body>
</html>

我签入了php.ini文件，websocket没有被注释掉

Websocket连接错误-ERR_CONNECTION_REFUSED
