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

复制代码
 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！");

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

42             Console.ReadKey();
