部署一个最简单的静态服务器

'use strict'; var url = require('url'), fs = require('fs'), http = require('http'), path = require('path'); var server = http.createServer(function (req, res) { var pathname = __dirname + url.parse(req.url).pathname; if (path.extname(pathname) == '') { pathname += '/'; } if (pathname.charAt(pathname.length - 1) == '/') { pathname += 'index.html'; } fs.exists(pathname, function (exists) { if (exists) { switch (path.extname(pathname)) { case '.html': res.writeHead(200, { 'Content-Type': 'text/html' }); break; case '.js': res.writeHead(200, { 'Content-Type': 'text/javascript' }); break; case '.css': res.writeHead(200, { 'Content-Type': 'text/css' }); break; case '.gif': res.writeHead(200, { 'Content-Type': 'text/gif' }); break; case '.jpg': res.writeHead(200, { 'Content-Type': 'text/jpeg' }); break; case '.png': res.writeHead(200, { 'Content-Type': 'text/png' }); break; default: res.writeHead(200, { 'Content-Type': 'application/octet-stream' }); } fs.readFile(pathname, function (err, data) { res.end(data); }); } else { res.writeHead(404, { 'Content-Type': 'text/html' }); res.end('<h1>4040 Not Found</h1>'); } }); }); server.listen(8080); console.log('server is running at http://localhost:8080 ...');

以上。
