1、web页面
1 <html lang="en" xmlns="http://www.w3.org/1999/xhtml"> 2 <head> 3 <meta charset="utf-8" /> 4 <title>WebSocket测试</title> 5 <style> 6 .div1 7 { 8 height:200px; 9 width:200px; 10 border:1px solid blue; 11 margin:auto; 12 } 13 h4 14 { 15 margin:auto; 16 } 17 </style> 18 <script> 19 var webSocket = {}; 20 //创建websockt 21 function CreateWebSocket() { 22 webSocket = new WebSocket("ws://127.0.0.1:30000"); 23 webSocket.onopen = WebSokectOnOpen; 24 webSocket.onmessage = WebSocketOnMessage; 25 webSocket.onclose = WebSocketOnClose; 26 }; 27 28 //建立连接事件 29 function WebSokectOnOpen() { 30 alert("已经打开连接！"); 31 webSocket.Send("WebSocketCreate Success!"); 32 }; 33 34 //监听事件 35 function WebSocketOnMessage(event) { 36 //监听来自客户端的数据 37 alert(event.data); 38 }; 39 40 function WebSocketOnClose() { 41 //监听来自客户端的数据 42 alert('和服务器断开连接'); 43 }; 44 45 //发送事件 46 function WebSocketSendMsg() { 47 //获取text中的值 48 var text = document.getElementById("Text1").value; 49 //发送到服务器 50 webSocket.send(text); 51 }; 52 </script> 53 </head> 54 <body οnlοad="CreateWebSocket()"> 55 <div class="div1"> 56 <h4>CSDN博客</h4> 57 <h4>By:LoveMiw</h4> 58 <input type="text" id="Text1" /> 59 <input type="button" οnclick="WebSocketSendMsg()" value="发送数据" /> 60 </div> 61 </body> 62 </html>
2、服务端C#代码 Nuget添加Fleck的引用，可以创建一个web应用程序
1 //客户端url以及其对应的Socket对象字典 2 IDictionary<string, IWebSocketConnection> dic_Sockets = new Dictionary<string, IWebSocketConnection>(); 3 //创建 4 5 WebSocketServer server = new WebSocketServer("ws://0.0.0.0:30000");//监听所有的的地址 6 //出错后进行重启 7 server.RestartAfterListenError = true; 8 9 //开始监听 10 server.Start(socket => 11 { 12 socket.OnOpen = () => //连接建立事件 13 { 14 //获取客户端网页的url 15 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 16 dic_Sockets.Add(clientUrl, socket); 17 Console.WriteLine(DateTime.Now.ToString() + "|服务器:和客户端网页:" + clientUrl + " 建立WebSock连接！"); 18 }; 19 socket.OnClose = () => //连接关闭事件 20 { 21 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 22 //如果存在这个客户端,那么对这个socket进行移除 23 if (dic_Sockets.ContainsKey(clientUrl)) 24 { 25 //注:Fleck中有释放 26 //关闭对象连接 27 //if (dic_Sockets[clientUrl] != null) 28 //{ 29 //dic_Sockets[clientUrl].Close(); 30 //} 31 dic_Sockets.Remove(clientUrl); 32 } 33 Console.WriteLine(DateTime.Now.ToString() + "|服务器:和客户端网页:" + clientUrl + " 断开WebSock连接！"); 34 }; 35 socket.OnMessage = message => //接受客户端网页消息事件 36 { 37 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; 38 Console.WriteLine(DateTime.Now.ToString() + "|服务器:【收到】来客户端网页:" + clientUrl + "的信息：\n" + message); 39 }; 40 }); 41 42 Console.ReadKey(); 43 foreach (var item in dic_Sockets.Values) 44 { 45 if (item.IsAvailable == true) 46 { 47 item.Send("服务器消息：" + DateTime.Now.ToString()); 48 } 49 } 50 Console.ReadKey(); 51 52 //关闭与客户端的所有的连接 53 foreach (var item in dic_Sockets.Values) 54 { 55 if (item != null) 56 { 57 item.Close(); 58 } 59 } 60 61 Console.ReadKey();
