最终结构为：
var express = require('express'), url = require('url');var app = express();app.use(function(req, res, next) { console.log('%s %s', req.method, req.url); next();});app.configure(function() { var pub_dir = __dirname + '/public'; app.set('port', process.env.PORT || 8080); app.engine('.html', require('ejs').__express); app.set('views', __dirname + '/views'); app.set('view engine', 'html'); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(express.cookieParser()); app.use(express.static(pub_dir)); app.use(app.router);});app.get('/*', function(req, res) { if (req.xhr) { var pathname = url.parse(req.url).pathname; res.sendfile('index.html', {root: __dirname + '/public' + pathname}); } else { res.render('index'); }});app.listen(app.get('port'));感谢大家。PD：使用模块ejs渲染html
