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)
