1、使用VS2019創建控制台程序
2、使用nuget包管理工具，引用Fleck
3、在Program中寫入以下方法
1 class Program 2 { 3 static void Main(string[] args) 4 { 5 //客戶端url以及其對應的Socket對象字典 6 IDictionary<string, IWebSocketConnection> dic_Sockets = new Dictionary<string, IWebSocketConnection>(); 7 //創建 8 9 WebSocketServer server = new WebSocketServer("ws://你的ip:50000");//監聽本機的地址（此處更換成你自己的IP和端口，此處要和客戶端保持一致） 10 //出錯后進行重啟 11 server.RestartAfterListenError = true; 12 13 //開始監聽 14 server.Start(socket => 15 { 16 socket.OnOpen = () => //連接建立事件 17 { 18 //獲取客戶端網頁的url 19 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 20 dic_Sockets.Add(clientUrl, socket); 21 Console.WriteLine(DateTime.Now.ToString() + "|服務器:和客戶端網頁:" + clientUrl + " 建立WebSock連接！"); 22 }; 23 socket.OnClose = () => //連接關閉事件 24 { 25 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 26 //如果存在這個客戶端,那么對這個socket進行移除 27 if (dic_Sockets.ContainsKey(clientUrl)) 28 { 29 //注:Fleck中有釋放 30 //關閉對象連接 31 //if (dic_Sockets[clientUrl] != null) 32 //{ 33 //dic_Sockets[clientUrl].Close(); 34 //} 35 dic_Sockets.Remove(clientUrl); 36 } 37 Console.WriteLine(DateTime.Now.ToString() + "|服務器:和客戶端網頁:" + clientUrl + " 斷開WebSock連接！"); 38 }; 39 socket.OnMessage = message => //接受客戶端網頁消息事件 40 { 41 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 42 Console.WriteLine(DateTime.Now.ToString() + "|服務器:【收到】來客戶端網頁:" + clientUrl + "的信息：\n" + message); 43 dic_Sockets.ToList().ForEach(s => s.Value.Send("Echo: " + message)); 44 }; 45 }); 46 47 Console.ReadKey(); 48 foreach (var item in dic_Sockets.Values) 49 { 50 if (item.IsAvailable == true) 51 { 52 item.Send("服務器消息：" + DateTime.Now.ToString()); 53 } 54 } 55 Console.ReadKey(); 56 57 //關閉與客戶端的所有的連接 58 foreach (var item in dic_Sockets.Values) 59 { 60 if (item != null) 61 { 62 item.Close(); 63 } 64 } 65 66 Console.ReadKey(); 67 } 68 }
4、運行啟動，查看效果，可以看到websocket服務端已經啟動，接下來是客戶端
5、創建websocket.html文件，並復制下面代碼
1 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 2 <html> 3 <head> 4 <title>websocket client</title> 5 <script type="text/javascript"> 6 var start = function () { 7 var inc = document.getElementById('incomming'); 8 var wsImpl = window.WebSocket || window.MozWebSocket; 9 var form = document.getElementById('sendForm'); 10 var input = document.getElementById('sendText'); 11 12 inc.innerHTML += "connecting to server ..<br/>"; 13 14 // create a new websocket and connect 15 window.ws = new wsImpl('ws://你的IP:50000/'); 16 17 // when data is comming from the server, this metod is called 18 ws.onmessage = function (evt) { 19 inc.innerHTML += evt.data + '<br/>'; 20 }; 21 22 // when the connection is established, this method is called 23 ws.onopen = function () { 24 inc.innerHTML += '.. connection open<br/>'; 25 }; 26 27 // when the connection is closed, this method is called 28 ws.onclose = function () { 29 inc.innerHTML += '.. connection closed<br/>'; 30 } 31 32 form.addEventListener('submit', function (e) { 33 e.preventDefault(); 34 var val = input.value; 35 ws.send(val); 36 input.value = ""; 37 }); 38 39 } 40 window.onload = start; 41 </script> 42 </head> 43 <body> 44 <form id="sendForm"> 45 <input id="sendText" placeholder="Text to send" /> 46 </form> 47 <pre id="incomming"></pre> 48 </body> 49 </html>
6、啟動打開客戶端網頁並發送文字，可以看到服務端接收到了客戶端發送來的消息，並將消息返回給所有的客戶端，一個簡單的websocket例子就完成了。
