C# Fleck的WebSocket使用
（1）. Web网页端代码
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"><head> <meta charset="utf-8" /> <title>WebSocket测试</title> <style> .div1 { height:88px; width:173px; border:1px solid blue; margin:auto; } h4 { margin:auto; } </style> <script> var webSocket = {}; //创建websockt function CreateWebSocket() { webSocket = new WebSocket("ws://127.0.0.1:30000"); webSocket.onopen = WebSokectOnOpen; webSocket.onmessage = WebSocketOnMessage; webSocket.onclose = WebSocketOnClose; }; //建立连接事件 function WebSokectOnOpen() { alert("已经打开连接！"); webSocket.Send("WebSocketCreate Success!"); }; //监听事件 function WebSocketOnMessage(event) { //监听来自客户端的数据 alert(event.data); }; function WebSocketOnClose() { //监听来自客户端的数据 alert('和服务器断开连接'); }; //发送事件 function WebSocketSendMsg() { //获取text中的值 var text = document.getElementById("Text1").value; //发送到服务器 webSocket.send(text); }; </script></head><body οnlοad="CreateWebSocket()"> <div class="div1"> <h4>CSDN博客</h4> <h4>By:LoveMiw</h4> <input type="text" id="Text1" /> <input type="button" οnclick="WebSocketSendMsg()" value="发送数据" /> </div></body></html>
（2）. 服务端C#代码
//上面是程序生成的using
using Fleck; namespace WebSocketTest{ class Program { static void Main(string[] args) { //客户端url以及其对应的Socket对象字典 IDictionary<string, IWebSocketConnection> dic_Sockets = new Dictionary<string, IWebSocketConnection>(); //创建 WebSocketServer server = new WebSocketServer("ws://0.0.0.0:30000");//监听所有的的地址 //出错后进行重启 server.RestartAfterListenError = true; //开始监听 server.Start(socket => { socket.OnOpen = () => //连接建立事件 { //获取客户端网页的url string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; dic_Sockets.Add(clientUrl, socket); Console.WriteLine(DateTime.Now.ToString() + "|服务器:和客户端网页:" + clientUrl + " 建立WebSock连接！"); }; socket.OnClose = () => //连接关闭事件 { string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; //如果存在这个客户端,那么对这个socket进行移除 if (dic_Sockets.ContainsKey(clientUrl)) { //注:Fleck中有释放 //关闭对象连接 //if (dic_Sockets[clientUrl] != null) //{ //dic_Sockets[clientUrl].Close(); //} dic_Sockets.Remove(clientUrl); } Console.WriteLine(DateTime.Now.ToString() + "|服务器:和客户端网页:" + clientUrl + " 断开WebSock连接！"); }; socket.OnMessage = message => //接受客户端网页消息事件 { string clientUrl = socket.ConnectionInfo.ClientIpAddress + ":" + socket.ConnectionInfo.ClientPort; Console.WriteLine(DateTime.Now.ToString() + "|服务器:【收到】来客户端网页:" + clientUrl + "的信息：\n" + message); }; }); Console.ReadKey(); foreach (var item in dic_Sockets.Values) { if (item.IsAvailable == true) { item.Send("服务器消息：" + DateTime.Now.ToString()); } } Console.ReadKey(); //关闭与客户端的所有的连接 foreach (var item in dic_Sockets.Values) { if (item != null) { item.Close(); } } Console.ReadKey(); } }}
