  • websocket 学习

    一、服务器端开发,

     public class SocketServer
        {
            static void Main()
            {
                try
                {
                    FleckLog.Level = LogLevel.Debug;
                    var allSockets = new List<IWebSocketConnection>();
              //读取配置文件,值格式 ws://192.168.100.100:1234
    string realNameUrl = Appsettings.app(new string[] { "WebApi", "RealNameUrl" }); var server = new WebSocketServer(realNameUrl); server.Start(socket => { socket.OnOpen = () => { Console.WriteLine("Open!"); allSockets.Add(socket); }; socket.OnClose = () => { Console.WriteLine("Close!"); allSockets.Remove(socket); }; socket.OnMessage = message => { Console.WriteLine(message); allSockets.ToList().ForEach(s => s.Send("Echo: " + message)); }; }); var input = Console.ReadLine(); while (input != "exit") { foreach (var socket in allSockets.ToList()) { socket.Send(input); } input = Console.ReadLine(); } } catch (Exception err) { FleckLog.Error(err.ToString()); } } }

    二、客户端测试。最简单方法:

    打开chrome——>F12——>输入如下代码:——>回车。如果是控制台,这时控制台中会显示出发送的内容:“websocekt测试”

    ws = new WebSocket("ws://192.168.100.100:1234");
    ws.onopen = function() { 
        ws.send('websocekt测试'); 
    };
    ws.onmessage = function(e) {
        alert("收到服务端的消息:" + e.data);
    };

    三、用静态html页面测试,代码如下:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <html>
    <head>
        <title>websocket client</title>
        <script type="text/javascript">
            var start = function () {
                var inc = document.getElementById('incomming');
                var wsImpl = window.WebSocket || window.MozWebSocket;
                var form = document.getElementById('sendForm');
                var input = document.getElementById('sendText');
    
                inc.innerHTML += "connecting to server ..<br/>";
    
                // create a new websocket and connect
                window.ws = new wsImpl('ws://192.168.100.100:1234/');
    
                // when data is comming from the server, this metod is called
                ws.onmessage = function (evt) {
                    inc.innerHTML += evt.data + '<br/>';
                };
    
                // when the connection is established, this method is called
                ws.onopen = function () {
                    inc.innerHTML += '.. connection open<br/>';
                };
    
                // when the connection is closed, this method is called
                ws.onclose = function () {
                    inc.innerHTML += '.. connection closed<br/>';
                }
    
                form.addEventListener('submit', function (e) {
                    e.preventDefault();
                    var val = input.value;
                    ws.send(val);
                    input.value = "";
                });
    
            }
            window.onload = start;
        </script>
    </head>
    <body>
        <form id="sendForm">
            <input id="sendText" placeholder="Text to send" />
        </form>
        <pre id="incomming"></pre>
    </body>
    </html>

     重点分享:

    如果想用域名访问,必须要发布成IIS,如iis的域名为:test.xxxx-zhongguo.com:7890,服务器端启动,还是用IP 如:192.168.100.100:1234

    客户端访问就可以用 test.xxxx-zhongguo.com:1234
