Fleck是一个开源的使用C#封装的WebSocket服务端工具库。

一、服务端搭建

这里选择在.net core 2.1框架下新建了一个控制台程序

在项目里使用NuGet引入Fleck包

NuGet引入Fleck包

其它方式也可以，最终引入项目里都是Fleck.dll

Fleck.dll

二、服务端实例

Github上的简单例子：

简单例子

简单实例：

using System;

using System.Collections.Generic;

using System.Linq;

using Fleck;

namespace ConsoleApp1

{

class Program

{

static voidMain(string[] args)

{

socketTest()；

}

Public static voidsocketTest()

{

//管理Socket

var allSockets = newList();

//配置地址

var server = newWebSocketServer("ws://127.168.0.100:50000");

//出错后进行重启

server.RestartAfterListenError = true;

//开始监听

server.Start(socket=>

{

//关联连接建立事件

socket.OnOpen= () =>

{

Console.WriteLine("Open!");

allSockets.Add(socket);

};

//关联连接关闭事件

socket.OnClose= () =>

{

Console.WriteLine("Close!");

allSockets.Remove(socket);

};

//接受客户端消息事件

socket.OnMessage = message =>

{

Console.WriteLine(message);

allSockets.ToList().ForEach(s => s.Send("bili: " +message));

};

});

var input =Console.ReadLine();

foreach (varsocket in allSockets.ToList())

{

socket.Send(input);

}

input =Console.ReadLine();

}

}

}

socket

三、客户端测试实例(网上copy)

websocket client

websocket client Test

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 ..
";

// create a new websocket and connect

window.ws = new wsImpl('ws://127.168.0.100:50000‘’);

// when data is comming from the server, this metod is called

ws.onmessage = function (evt) {

inc.innerHTML += evt.data + '
';

};

// when the connection is established, this method is called

ws.onopen = function () {

inc.innerHTML += '.. connection open
';

};

// when the connection is closed, this method is called

ws.onclose = function () {

inc.innerHTML += '.. connection closed
';

}

form.addEventListener('submit', function (e) {

e.preventDefault();

var val = input.value;

ws.send(val);

input.value = "";

});

}

window.onload = start;

test

浏览器打开网页就可以测试了。
