本文共 18430 字，大约阅读时间需要 61 分钟。

本文是简述了Websocket的服务端和客户端的实时通讯过程，Websocket的服务端和客户端的具体使用使用了2种Websocket的服务端和2种客户端。

以下代码使用的是Visual Studio 2019 Enterprise版本，控制台项目使用的是 .NETFramework,Version=v4.7.2，同时为了调试方便，做了log4net日志处理，log4net日志的使用可以百度

 

Websocket服务端

1、新建项目ConsoleWebsocketServer

 

2、项目右键 管理Nuget程序包，，搜索  SuperWebSocketNETServer，添加即可

3、新建文件夹ServerEntities，然后再该文件夹下添加HttpAndWebsocket和ConsoleAppWebsocketServer这两个类，代码如下

HttpAndWebsocket类

 

using System;

using System.Net;
using System.Net.WebSockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleWebsocketServer.ServerEntities

{
public class HttpAndWebsocket
{
public async void Start(string url)
{
string url1 = "http://+:80/";
int Port = 1234;
HttpListener httpListener = new HttpListener();
httpListener.Prefixes.Add("http://+:" + Port + "/");
httpListener.Start();
while (true)
{
try
{
HttpListenerContext httpListenerContext = await httpListener.GetContextAsync();
try
{
if (httpListenerContext.Request.IsWebSocketRequest)
{
ProcessRequest(httpListenerContext);
}
}
catch (Exception)
{
httpListenerContext.Response.StatusCode = 400;
httpListenerContext.Response.Close();
}
}
catch (Exception)
{
throw;
}
}
}

private async void ProcessRequest(HttpListenerContext listenerContext)

{
HttpListenerWebSocketContext httpListenerWebSocket;

try

{
httpListenerWebSocket = await listenerContext.AcceptWebSocketAsync(null);
}
catch (Exception)
{
listenerContext.Response.StatusCode = 500;
listenerContext.Response.Close();
return;
}
WebSocket webSocket = httpListenerWebSocket.WebSocket;
try
{

while (webSocket.State == WebSocketState.Open)

{
byte[] returnBytes = new byte[10240];
WebSocketReceiveResult webSocketReceiveResult = await webSocket.ReceiveAsync(new ArraySegment<byte>(returnBytes), CancellationToken.None);
string ReceivesData = Encoding.UTF8.GetString(returnBytes, 0, webSocketReceiveResult.Count);
ReceivesData = $"我已经收到数据：{ReceivesData}";
returnBytes = Encoding.UTF8.GetBytes(ReceivesData);
await webSocket.SendAsync(new ArraySegment<byte>(returnBytes), WebSocketMessageType.Text, true, CancellationToken.None);
await Task.Delay(TimeSpan.FromSeconds(3));
}
}
catch (Exception)
{

throw;

}
finally
{
if (webSocket != null)
{
webSocket.Dispose();
}
}
}
}
}

 

ConsoleAppWebsocketServer类

 

using SuperWebSocket;

using System;
using System.Web;

namespace ConsoleWebsocketServer.ServerEntities

{
/// <summary>
/// SuperWebSocket服务端
/// </summary>
public class ConsoleAppWebsocketServer
{
public static WebSocketServer ws = null;

public void Start()

{
ws = new WebSocketServer();
ws.NewSessionConnected += Ws_NewSessionConnected;
ws.NewMessageReceived += Ws_NewMessageReceived;
ws.SessionClosed += Ws_SessionClosed;
if (!ws.Setup("127.0.0.1", 1234))
{
Console.WriteLine("ChatWebSocket 设置WebSocket服务侦听地址失败");
return;
}

if (!ws.Start())

{
Console.WriteLine("ChatWebSocket 启动WebSocket服务侦听失败");
return;
}
while (true)
{

}

}

public void Ws_NewSessionConnected(WebSocketSession session)

{
Console.WriteLine("{0:HH:MM:ss} 与客户端:{1}创建新会话", DateTime.Now, GetSessionName(session));
var msg = string.Format("{0:HH:MM:ss} {1} 进入聊天室", DateTime.Now, GetSessionName(session));

SendToAll(session, msg);

}

private void Ws_NewMessageReceived(WebSocketSession session, string value)

{
var msg = string.Format("{0:HH:MM:ss} {1} 说: {2}", DateTime.Now, GetSessionName(session), value);
Console.WriteLine($"{msg}");
SendToAll(session, msg);
}

public void Ws_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)

{
Console.WriteLine("{0:HH:MM:ss} 与客户端:{1}的会话被关闭 原因：{2}", DateTime.Now, GetSessionName(session), value);
var msg = string.Format("{0:HH:MM:ss} {1} 离开聊天室", DateTime.Now, GetSessionName(session));
SendToAll(session, msg);
}

/// <summary>

/// </summary>
/// <returns></returns>
public void StartWebsocket()
{
if (!ws.Setup("127.0.0.1", 1234))
{
Console.WriteLine("ChatWebSocket 设置WebSocket服务侦听地址失败");
return;
}

if (!ws.Start())

{
Console.WriteLine("ChatWebSocket 启动WebSocket服务侦听失败");
return;
}

Console.WriteLine("ChatWebSocket 启动服务成功");

}

/// <summary>

/// 停止侦听服务
/// </summary>
public void Stop()
{

if (ws != null)

{
ws.Stop();
}
}

public string GetSessionName(WebSocketSession session)

{
return HttpUtility.UrlDecode(session.Path.TrimStart('/'));
}

public void SendToAll(WebSocketSession session, string msg)

{
foreach (var sendSession in session.AppServer.GetAllSessions())
{
sendSession.Send(msg);
}
}
}
}

 

4、ConsoleWebsocketServer的Program.cs 代码如下

 

using ConsoleWebsocketServer.ServerEntities;

using SuperWebSocket;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;

namespace ConsoleWebsocketServer

{
class Program
{
public static WebSocketServer ws = null;
static void Main(string[] args)
{
#region 启动http服务接受websocket请求
Console.WriteLine("启动http服务的WebSocket服务");
HttpAndWebsocket httpAndWebsocket = new HttpAndWebsocket();
httpAndWebsocket.Start("ws://127.0.0.1:1234");
Console.WriteLine("ChatWebSocket 启动服务成功");
Console.WriteLine("按 Enter 退出...");
Console.ReadKey();
#endregion

#region 启动websocket服务接受websocket请求

// return;
//}

//Console.WriteLine("ChatWebSocket 启动服务成功");

//Console.WriteLine("按 Enter 推出...");
//Console.ReadKey();
//ws.Stop();
#endregion
}

public static void Ws_NewSessionConnected(WebSocketSession session)

{
Console.WriteLine("{0:HH:MM:ss} 与客户端:{1}创建新会话", DateTime.Now, GetSessionName(session));
var msg = string.Format("{0:HH:MM:ss} {1} 进入聊天室", DateTime.Now, GetSessionName(session));

SendToAll(session, msg);

}

}

public static void Ws_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)

{

{
Console.WriteLine("ChatWebSocket 启动WebSocket服务侦听失败");
return;
}

Console.WriteLine("ChatWebSocket 启动服务成功");

 

}

/// <summary>

public static void Stop()
{

if (ws != null)

{
ws.Stop();
}
}

public static string GetSessionName(WebSocketSession session)

}

public static void SendToAll(WebSocketSession session, string msg)

{
foreach (var sendSession in session.AppServer.GetAllSessions())
{
sendSession.Send(msg);
}
}
}
}

 

 

Websocket客户端

 

1、新建项目ConsoleWebsocketClient

 

 

2、项目右键 管理Nuget程序包，，搜索  log4net，WebSocket4NET，添加即可

 

3、新建文件夹ClientEntities，然后再该文件夹下添加ClientWebsocketEntity和ConsoleAppWebsocketClient这两个类，代码如下

ConsoleAppWebsocketClient类

 

using System;

using System.Collections.Generic;
using System.Text;
using System.Threading;

namespace ConsoleWebsocketClient.ClientEntities

{

4、ConsoleWebsocketClient的Program.cs 代码如下

 

using ConsoleWebsocketClient.ClientEntities;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleWebsocketClient

{

//Thread thread = new Thread(WebSocketSendmessage);
//thread.IsBackground = true;
//thread.Start();
//Console.ReadKey();
#endregion

}

public static void Addlog(string sss)

{
Console.WriteLine(sss);
}

public static void WebSocketSendmessage()

{
int s = 88;
while (true)
{
webSocket4Net.Send(s.ToString());
s++;
Thread.Sleep(TimeSpan.FromSeconds(3));

}

}

private static void WebSocket4Net_Error(object sender, SuperSocket.ClientEngine.ErrorEventArgs e)

{
//throw new NotImplementedException();
}

private static void WebSocket4Net_Opened(object sender, EventArgs e)

{
Console.WriteLine($"begin#123456");
byte[] bytess = Encoding.Default.GetBytes($"begin#123456");
IList<ArraySegment<byte>> list = new List<ArraySegment<byte>>();
list.Add(new ArraySegment<byte>(bytess));
webSocket4Net.Send(list);
}

private static void WebSocket4Net_MessageReceived(object sender, WebSocket4Net.MessageReceivedEventArgs e)

{
try
{
string returnMessage = e.Message;
if (string.IsNullOrEmpty(returnMessage))
{
return;
}
Console.WriteLine(returnMessage);
}
catch (Exception ex)
{

}

finally
{

}

}
}
}

 

5、ConsoleWebsocketClient的App.config 代码如下

<?xml version="1.0" encoding="utf-8" ?>

<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Log\Log.txt" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="100" />
<param name="MaximumFileSize" value="2MB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-15p %d [%c] %m %n" />
</layout>
</appender>
<root>
<level value="all" />
<appender-ref ref="RollingLogFileAppender" />
</root>
</log4net>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
</startup>
</configuration>

 

 

5、为了测试方便添加了HTML文件websockettest.html

<!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" οnclick="Connect();">Connect</button>
<button id="send" οnclick="Send();">Send</button>
<button id="close" οnclick="Close();">Close</button>

</body>

</html>

 

 

以上ConsoleWebsocketServer项目和ConsoleWebsocketClient项目都建好了，就可以运行了，其中可以设置两种Websocket服务端和Websocket客户端（websockettest.html网页端，也是客户端）

 服务端

 

客户端

 

 

 运行结果
