1 //客戶端url以及其對應的Socket物件字典
2 IDictionary<string, IWebSocketConnection> dic_Sockets = new Dictionary<string, IWebSocketConnection>();
3 //建立
4
5 WebSocketServer server = new WebSocketServer("ws://0.0.0.0:30000");//監聽所有的的地址
6 //出錯後進行重啟
7 server.RestartAfterListenError = true;
8
9 //開始監聽
10 server.Start(socket =>
11 {
12 socket.OnOpen = () => //連線建立事件
13 {
14 //獲取客戶端網頁的url
15 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort;
16 dic_Sockets.Add(clientUrl, socket);
17 Console.WriteLine(DateTime.Now.ToString() + "|伺服器:和客戶端網頁:" + clientUrl + " 建立WebSock連線！");
18 };
19 socket.OnClose = () => //連線關閉事件
20 {
21 string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort;
22 //如果存在這個客戶端,那麼對這個socket進行移除
23 if (dic_Sockets.ContainsKey(clientUrl))
24 {
25 //注:Fleck中有釋放
26 //關閉物件連線
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() + "|伺服器:和客戶端網頁:" + clientUrl + " 斷開WebSock連線！");
34 };
35 socket.OnMessage = message => //接受客戶端網頁訊息事件

39 };
40 });

42 Console.ReadKey();
43 foreach (var item in dic_Sockets.Values)
44 {
45 if (item.IsAvailable == true)
46 {
47 item.Send("伺服器訊息：" + DateTime.Now.ToString());
48 }
