engine.io是一个socket.io的抽象实现，作为socket.io的服务器和浏览器之间交换的数据的传输层。它不会取代Socket.IO，它只是抽象出固有的复杂性，支持多种浏览器，设备和网络的实时数据交换。Server
(A) Listening on a port
var engine = require('engine.io') , server = engine.listen(80) server.on('connection', function (socket) { socket.send('utf 8 string'); });(B) Intercepting requests for a http.Server
var engine = require('engine.io') , http = require('http').createServer().listen(3000) , server = engine.attach(http) server.on('connection', function (socket) { socket.on('message', function () { }); socket.on('close', function () { }); });(C) Passing in requests
var engine = require('engine.io') , server = new engine.Server() server.on('connection', function (socket) { socket.send('hi'); }); // … httpServer.on('upgrade', function (req, socket, head) { server.handleUpgrade(req, socket, head); }); httpServer.on('request', function (req, res) { server.handleRequest(req, res); });Client
<script src="/path/to/engine.io.js"></script> <script> var socket = new eio.Socket('ws://localhost/'); socket.on('open', function () { socket.on('message', function (data) { }); socket.on('close', function () { }); }); </script>
