聊天室架构

所有连接的客户全部转发（类似广播）

点对点的那种就把connection存起来，大多数使用redis存起来，用的时候取出对应的connection

客户端: client.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div id="msg"></div>
    <input type="text" id="text">
    <input type="submit" value="发送" onclick="send()">

    <script>
        var websocket = new WebSocket('ws://localhost:8080');
        // ws ---> http
        // wss ---> https

        websocket.readyState
        // 0 链接还没有建立
        // 1 连接建立成功
        // 2 连接正在关闭
        // 3 连接已经关闭
        websocket.onopen = function () {
            console.log(websocket.readyState)
        }
        
        function send() {
            var text = document.getElementById('text').value
            websocket.send(text)
        }

        websocket.onmessage = function (backMsg){
            console.log(backMsg.data)
        }
    </script>

</body>
</html>

服务端： server.js

var WebSocket = require('websocket').server
var http = require('http')

// 创建httpServer
var httpServer = http.createServer().listen(8080,function (){
    console.log('http://127.0.0.1:8080')
})

// 创建webSocketServer
var wsServer = new WebSocket({
    httpServer:httpServer,
    autoAcceptConnections:false
})

var connectionArr = []


wsServer.on('request',function (request){
    var connection = request.accept()
    // 将connection信息添加到列表中存起来
    connectionArr.push(connection)

    connection.on('message',function (msg){
        console.log(msg)

        // 发送给客户端
        for (let i = 0; i < connectionArr.length; i++) {
            connectionArr[i].send(msg.utf8Data)
        }

    })
})
