.net mvc使用websocket服务器及客户端简易代码

.net MVC服务端

Func<AspNetWebSocketContext, Task> func = new Func<AspNetWebSocketContext, Task>(async (socketContext) => {
WebSocket socket = socketContext.WebSocket;
await socket.SendAsync(GetText("我是服务器,连接成功"), WebSocketMessageType.Text, true, CancellationToken.None);

while (socket.State == WebSocketState.Open)
{
ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);
WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None);
// 解析消息内容
string userMessage = Encoding.UTF8.GetString(buffer.Array, 0, result.Count);

//是否关闭链接
if (result.MessageType == WebSocketMessageType.Close)
{
break;
}
}
});

System.Web.HttpContext.Current.AcceptWebSocketRequest(func);

　　

　　

        public static ArraySegment<byte> GetText(string text)
        {
            return new ArraySegment<byte>(Encoding.UTF8.GetBytes(text));
        }

网页客户端

   var url = "ws://localhost:55939";
        var socket;
        function connect() {
            var webSocketUrl = url + "?UserName=qqqq" + new Date();
            //注意：下面这行代码执行之后就已经调通到后台的MyWebSocket方法中了。
            socket = new WebSocket(webSocketUrl)
            //链接打开的时候触发
            socket.onopen = function () {
                console.log("链接已打开");
                // 定时发送一个消息给服务器发送心跳包 服务器接收到心跳包以后马上就再回复一个消息给客户端
                // 如果我发现十秒钟或者在间隔时间内 接受不到服务器回复的心跳消息 我就认为连接掉线
                // 这时候就需要断线 connect();
            }
            // 接受服务器发送过来的消息
            socket.onmessage = function (evt) {
                console.log(evt.data);
            }
            // 异常的时候触发方法
            socket.onerror = function (evt) {
                console.log(evt);
            }
            // 链接关闭的时候触发
            socket.onclose = function () {
                console.log("连接关闭了");
            }
            
        }
        function Send() {
            socket.send(document.getElementById("msg").value);
        }

　　C#客户端

ClientWebSocket socket = new ClientWebSocket();
            IAsyncResult asyncResult = socket.ConnectAsync(new Uri("wss://xxxxxx"), CancellationToken.None);

            bool isSuccess = asyncResult.AsyncWaitHandle.WaitOne(Timeout.Infinite, true);
if (isSuccess&& socket.State == WebSocketState.Open)
{
//连接成功
}

            while (socket.State == WebSocketState.Open)
            {
                ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);
                WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None);
                string userMessage = Encoding.UTF8.GetString(buffer.Array, 0, result.Count);

            }
