.net使用websocket
客户端:
<head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script src="Scripts/jquery-3.4.1.min.js"></script> <script> var ws; $().ready(function () { $('#conn').click(function () { ws = new WebSocket('ws://' + window.location.hostname + ':' + window.location.port + '/Handler1.ashx'); $('#tips').text('正在连接'); ws.onopen = function () { $('#tips').text('已经连接'); } ws.onmessage = function (evt) { $('#tips').html($('#tips').html() + '<br/>' + evt.data); } ws.onerror = function (evt) { $('#tips').text(JSON.stringify(evt)); } ws.onclose = function () { $('#tips').text('已经关闭'); } }); $('#close').click(function () { ws.close(); }); $('#send').click(function () { if (ws.readyState == WebSocket.OPEN) { ws.send($('#content').val()); } else { $('#tips').text('连接已经关闭'); } }); }); </script> </head> <body> <form id="form1" runat="server"> <div> <br /> <input id="conn" type="button" value="连接" /> <input id="close" type="button" value="关闭" /> <span id="tips"></span> <input id="content" type="text" /> <input id="send" type="button" value="发送" /> </div> </form> </body>
服务端(一般处理程序):
using System; using System.Collections.Generic; using System.Linq; using System.Net.WebSockets; using System.Text; using System.Threading; using System.Web; using System.Web.WebSockets; namespace WebApplication1 { /// <summary> /// Handler1 的摘要说明 /// </summary> public class Handler1 : IHttpHandler { public static List<WebSocket> list = new List<WebSocket>(); public void ProcessRequest(HttpContext context) { if (context.IsWebSocketRequest) { context.AcceptWebSocketRequest(ProcessChat); } } private async System.Threading.Tasks.Task ProcessChat(AspNetWebSocketContext context) { WebSocket socket = context.WebSocket; if (!list.Any(x=>x==socket)) { list.Add(socket); } while (true) { ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[2048]); WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None); if (socket.State == WebSocketState.Open) { string userMsg = Encoding.UTF8.GetString(buffer.Array, 0, result.Count); userMsg = "你发送了:" + userMsg + "于" + DateTime.Now.ToLongTimeString(); buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(userMsg)); foreach (var item in list) { if (item==socket) { await item.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None); } } } else { //关闭连接 if (result.MessageType == WebSocketMessageType.Close) { await socket.CloseAsync(WebSocketCloseStatus.Empty, string.Empty, CancellationToken.None);//如果client发起close请求,对client进行ack list.Remove(socket); break; } } } } public bool IsReusable { get { return false; } } } }
