原生nodejs使用websocket代码分享

安装：

npm  install  ws

服务端（nodejs）：

var WebSocketServer = require('ws').Server, wss = new WebSocketServer({ port: 8080 }); wss.on('connection', function (ws) { console.log('client connected'); ws.on('message', function (message) { console.log(message); }); });

客户端：

<script> var ws = new WebSocket("ws://localhost:8080"); ws.onopen = function (e) { console.log('Connection to server opened'); sendMessage(); } function sendMessage() { ws.send('hello'); } </script>
