本實例可通過web網頁端進行測試，下面直接上代碼。
首先要在NuGet導入“Fleck”包，需 .NET Framework 4.5及以上。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
namespace Fleck.Samples.ConsoleApp
{
class Server
{
static void Main()
{
FleckLog.Level = LogLevel.Debug;
var allSockets = new List<IWebSocketConnection>();
var server = new WebSocketServer("ws://10.10.10.99:50000");
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();
}
}
}
}
接下來就是測試階段，首先運行窗體程序。
測試方法1：打開瀏覽器，F12進入調試模式，在Console中輸入測試代碼。（我使用的是谷歌瀏覽器）
ws = new WebSocket("ws://10.10.10.99:50001");
ws.onopen = function() {
ws.send('websocekt測試');
};
ws.onmessage = function(e) {
alert("收到服務端的消息：" + e.data);
};
輸入完畢后按回車執行，這時就可以在命令行中看到傳過來的數據了。
測試方法2：寫html腳本進行通信。
<!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://10.10.10.99:50000/');
// 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>
到這里就結束了，哪里說得不明確希望大家加以補充。
