node.js服务端
先要安装ws模块的支持
npm install ws
服务端（server.js）
var gws;var WebSocketServer = require(‘ws‘).Server, ???wss = new WebSocketServer({ port: 9000 });wss.on(‘connection‘, function (ws) { ???gws = ws; ???console.log(‘client connected‘); ???ws.on(‘message‘, function (message) { ???????console.log(message); ???????setInterval(show,5000);//每隔5秒 服务端向浏览器 推送消息 ???});});function show(){ ???gws.send(1122);}shell> node server.js
浏览器客户端
<script> ???if (window.WebSocket) ???{ ???????console.log("支持"); ???}else ???{ ???????console.log("不支持"); ???} ???var ws = new WebSocket(‘ws://localhost:9000‘); ???ws.onopen = function() ???????{ ?console.log("open"); ???????????ws.send("hello"); ???????}; ???ws.onmessage = function(evt) ???{ ???????console.log(evt.data) ???}; ???ws.onclose = function(evt) ???{ ???????console.log("WebSocketClosed!"); ???}; ???ws.onerror = function(evt) ???{ ???????console.log("WebSocketError!"); ???};</script>我写的websocket推送例子，每隔5秒服务器向客户端浏览器发送消息(node.js和浏览器)
