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

 

步骤:

1、连接socket。并带参数。

2、socket接受到连接信息请求,可以记录下对应IP和port,根据定义进行解析参数。 还可以把所有的连接信息(如机器识别码),进行缓存

3、连接成功后,可以通过IP和port向指定客户端发送信息。

4、其他接口向socket直接发送信息(如下)。

5、接受到信息,可以对缓存连接信息进行过滤,向对应(根据机器识别码)的客户端推送及时信息。

其他使用:

 

  private  readonly ClientWebSocket webSocket = new ClientWebSocket();
        private readonly CancellationToken _cancellation = new CancellationToken();

        /// <summary>
        /// 发送连接
        /// 支持中文
        /// </summary>
        /// <param name="serverIP">目标IP</param>
        /// <param name="message">发送信息</param>
        /// <param name="port">目标端口</param>
        public  async Task tcpSendText(string serverIP, int port, object message)
        {
            await webSocket.ConnectAsync(new Uri("ws://"+ serverIP + ":"+ port ), _cancellation);
            var sendBytes = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(message));//发送的数据
            var bsend = new ArraySegment<byte>(sendBytes);
            await webSocket.SendAsync(bsend, WebSocketMessageType.Text, true, _cancellation);
            await webSocket.CloseAsync(WebSocketCloseStatus.NormalClosure, "1", _cancellation);
            webSocket.Dispose();
        }
