H5WebSocket前后台代碼

1、效果圖

2、后台代碼：

 public void Demo() {
            //return "Hello World";
            HttpContextBase content = this.HttpContext;
            content.AcceptWebSocketRequest(ProcessChat);
            //return "I am a beautiful girl";
        }

        private async Task ProcessChat(AspNetWebSocketContext context)
        {
            //HttpContextBase  content = this.HttpContext;
            WebSocket socket = context.WebSocket;
            while (true)
            {
                if (socket.State == WebSocketState.Open)
                {
                    ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[2048]);
                    WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None);
                    string userMsg = Encoding.UTF8.GetString(buffer.Array, 0, result.Count);
                    userMsg = "你發送了：" + userMsg + "於" + DateTime.Now.ToLongTimeString();
                    buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(userMsg));
                    await socket.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None);
                }
                else
                {
                    break;
                }
            }
        }
    }

3、前端代碼

@{
    ViewBag.Title = "Home Page";
}


    

    <script src="~/Scripts/jquery-1.10.2.min.js"></script>
    <script type="text/javascript">

        var ws;
        $().ready(function () {
            $('#conn').click(function () {
                ws = new WebSocket('ws://' + window.location.hostname + ':' + window.location.port + '/Home/Demo');
                $('#tips').text('正在連接');
                ws.onopen = function () {
                    $('#tips').text('已經連接');
                }
                ws.onmessage = function (evt) {
                    $('#tips').text(evt.data);
                }
                ws.onerror = function (evt) {
                    $('#tips').text(JSON.stringify(evt));
                }
                ws.onclose = function () {
                    $('#tips').text('已經關閉');
                }
            });

            $('#close').click(function () {
                ws.close();
            });

            $('#send').click(function () {
                if (ws.readyState == WebSocket.OPEN) {
                    ws.send($('#content').val());
                }
                else {
                    $('#tips').text('連接已經關閉');
                }
            });

        });
    </script>
<br/>


<div class="row">

    <form id="form1" runat="server">
        <div>

            <input id="conn" type="button" value="連接" />
            <input id="close" type="button" value="關閉" />
            <span id="tips"></span>
            <input id="content" type="text" />
            <input id="send" type="button" value="發送" />
        </div>
    </form>

   
</div>

4、總結：看網上Websocket的實例后台一般都是ashx的樣例，研究了好久才知道mvc的action也可以寫成websocket。非常感謝eleven老師的指導。讓我今天對websocket有了一定的了解，並且有信心堅持下去。也謝謝這位大牛的文章，讓我解決了問題
