SuperWebSocket实现服务端和WebSocket4Net实现客户端具体实现如下：
SuperWebSocket实现服务端
注：本作者是基于vs2019 enterprise版本，所有项目均为.Net Framwork4.7版本(因为WebSocket需求是.Net Framwork4.0以上版本）
1、新建控制台项目ConsoleAppWebsocketServer，作为服务端，选择项目右键管理Nuget程序包，搜索 SuperWebSocket ，选择SuperWebSocketNETServer，点击右侧 安装，
等待安装完成，安装完成以后，项目会多出很多引用库，如下
，
项目的Program.cs内容如下：
using SuperWebSocket;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
namespace ConsoleAppWebsocketServer
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("服务端");
WebSocketServer webSocketServer = new WebSocketServer();
webSocketServer.NewSessionConnected += WebSocketServer_NewSessionConnected;
webSocketServer.NewMessageReceived += WebSocketServer_NewMessageReceived;
webSocketServer.SessionClosed += WebSocketServer_SessionClosed;
if (!webSocketServer.Setup("127.0.0.1", 1234))
{
Console.WriteLine("设置服务监听失败！");
}
if (!webSocketServer.Start())
{
Console.WriteLine("启动服务监听失败！");
}
Console.WriteLine("启动服务监听成功！");
Console.WriteLine("按任意键结束。。。");
Console.ReadKey();
webSocketServer.Dispose();
}
private static void WebSocketServer_NewSessionConnected(WebSocketSession session)
{
string msg = $"{DateTime.Now.ToString("HH:mm:ss")} 客户端：{GetwebSocketSessionName(session)} 加入";
Console.WriteLine($"{msg}");
SendToAll(session, msg);
}
private static void WebSocketServer_NewMessageReceived(WebSocketSession session, string value)
{
string msg = $"{DateTime.Now.ToString("HH:mm:ss")} 服务端收到客户端：{GetwebSocketSessionName(session)}发送数据：{value}";
Console.WriteLine($"{msg}");
SendToAll(session, value);
}
private static void WebSocketServer_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)
{
string msg = $"{DateTime.Now.ToString("HH:mm:ss")} 客户端：{GetwebSocketSessionName(session)}关闭，原因：{value}";
Console.WriteLine($"{msg}");
SendToAll(session, msg);
}
/// <summary>
/// 获取webSocketSession的名称
/// </summary>
/// <param name="webSocketSession"></param>
public static string GetwebSocketSessionName(WebSocketSession webSocketSession)
{
return HttpUtility.UrlDecode(webSocketSession.SessionID);
}
/// <summary>
/// 广播，同步推送消息给所有的客户端
/// </summary>
/// <param name="webSocketSession"></param>
/// <param name="msg"></param>
public static void SendToAll(WebSocketSession webSocketSession, string msg)
{
foreach (var item in webSocketSession.AppServer.GetAllSessions())
{
item.Send(msg);
}
}
}
}
WebSocket4Net实现客户端
2、新建控制台项目ConsoleAppWebsocketClient，作为客户端，选择项目右键管理Nuget程序包，为了测试SuperWebSocket作为服务端的功能，本文客户端使用了WebSocket4Net，同样也可以使用 SuperWebSocket ，本项目选择WebSocket4Net，点击右侧 安装，等待安装完成，安装完成之后，同样项目下会多一些引用库，如下：
项目的Program.cs内容如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WebSocket4Net;
using System.Threading;
namespace ConsoleAppWebsocketClient
{
class Program
{
public static WebSocket webSocket4Net = null;
static void Main(string[] args)
{
Console.WriteLine("客户端");
webSocket4Net = new WebSocket("ws://127.0.0.1:1234");
webSocket4Net.Opened += WebSocket4Net_Opened;
webSocket4Net.MessageReceived += WebSocket4Net_MessageReceived;
webSocket4Net.Open();
Console.WriteLine("客户端连接成功！");
Thread thread = new Thread(ClientSendMsgToServer);
thread.IsBackground = true;
thread.Start();
Console.WriteLine("按任意键结束。。。");
Console.ReadKey();
webSocket4Net.Dispose();
}
public static void ClientSendMsgToServer()
{
int i = 88;
while (true)
{
//Console.WriteLine($"客户端发送数据{i++}");
webSocket4Net.Send($"{i++}");
Thread.Sleep(TimeSpan.FromSeconds(5));
}
}
private static void WebSocket4Net_MessageReceived(object sender, MessageReceivedEventArgs e)
{
Console.WriteLine($"服务端回复数据:{e.Message}！");
}
private static void WebSocket4Net_Opened(object sender, EventArgs e)
{
webSocket4Net.Send($"客户端准备发送数据！");
}
}
}
3、测试
为了更好的看到测试效果，又多使用了js客户端来测试，添加html文件，命名websockettest.html，内容如下：
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="content-type" content="text/html" />
<meta name="author" content="https://www.baidu.com" />
<title>websocket test</title>
<script>
var socket;
function Connect(){
try{
socket=new WebSocket('ws://127.0.0.1:1234');
}catch(e){
alert('error');
return;
}
socket.onopen = sOpen;
socket.onerror = sError;
socket.onmessage= sMessage;
socket.onclose= sClose;
}
function sOpen(){
alert('connect success!');
}
function sError(e){
alert("error " + e);
}
function sMessage(msg){
document.getElementById("msgrecv").value = msg.data;
}
function sClose(e){
alert("connect closed:" + e.code);
}
function Send(){
socket.send(document.getElementById("msg").value);
}
function Close(){
socket.close();
}
</script>
</head>
<body>
<input id="msg" type="text" size = "200" >
<input id="msgrecv" type="text" size = "200">
<button id="connect" onclick="Connect();">Connect</button>
<button id="send" onclick="Send();">Send</button>
<button id="close" onclick="Close();">Close</button>
</body>
</html>
4、运行结果
到此位置所有的准备工作都完成了，一个服务端ConsoleAppWebsocketServer，两个客户端(ConsoleAppWebsocketClient，websockettest.html)，那么接下来运行项目
解决方案 右键，属性，设置启动项目如下：
启动服务端ConsoleAppWebsocketServer，客户端ConsoleAppWebsocketClient之后，再去手动点击websockettest.html，
运行效果：
