我一直在使用asp.net和一些javascript制作聊天系统的一些教程,但我遇到了问题。该项目工作正常,直到它尝试创建websocket。而不是创建它并继续前进只是给了我错误:
失败:连接建立错误:net:ERR_CONNECTION_REFUSED
我现在一直试图解决这个问题大约3个小时,但我没有运气。我尝试过使用xampp并运行apache,但它还没有工作。这是我的代码: 的index.html:
<!doctype html>
<html>
<head>
<script src="Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var name = prompt('what is your name?:');
var url = 'ws://' + window.location.hostname + window.location.pathname.replace('index.html', 'ws.ashx') + '?name=' + name;
alert('Connecting to: ' + url);
ws = new WebSocket(url);
ws.onopen = function () {
$('#messages').prepend('Connected <br/>');
$('#cmdSend').click(function () {
ws.send($('#txtMessage').val());
$('#txtMessage').val('');
});
};
ws.onmessage = function (e) {
$('#chatMessages').prepend(e.data + '<br/>');
};
$('#cmdLeave').click(function () {
ws.close();
});
ws.onclose = function () {
$('#chatMessages').prepend('Closed <br/>');
};
ws.onerror = function (e) {
$('#chatMessages').prepend('Oops something went wront <br/>');
};
});
</script>
</head>
<body>
<input id="txtMessage" />
<input id="cmdSend" type="button" value="Send" />
<input id="cmdLeave" type="button" value="Leave" />
<br />
<div id="chatMessages" />
</body>
</html>
ws.ashx:
public class WSHttpHandler:IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
if (context.IsWebSocketRequest)
context.AcceptWebSocketRequest(new TestWebSocketHandler());
}
public bool IsReusable
{
get
{
return false;
}
}
}
和TestWebSocketHandler.cs:
public class TestWebSocketHandler : WebSocketHandler
{
private static WebSocketCollection clients = new WebSocketCollection();
private string name;
public override void OnOpen()
{
this.name = this.WebSocketContext.QueryString["name"];
clients.Add(this);
clients.Broadcast(name + " has connected.");
}
public override void OnMessage(string message)
{
clients.Broadcast(string.Format("{0} said: {1}", name, message));
}
public override void OnClose()
{
clients.Remove(this);
clients.Broadcast(string.Format("{0} has gone away.", name));
}
}
