Python里面有个简单的命令python -m SimpleHTTPServer，但不支持目录访问，所以自己捣鼓了一个。用了很久了，放这儿存档。

var http = require('http'),  url = require('url'),  path = require('path'),  fs = require('fs'),  util = require('util'),  querystring = require('querystring');var rootpath = process.cwd();var MIMETYPES = {  'css' : 'text/css',  'htm' : 'text/html',  'html': 'text/html',  'js'  : 'application/javascript',  'ico' : 'image/x-icon',  'jpg' : 'image/jpeg',  'png' : 'image/png',  'mp3' : 'audio/mp3',  'ogg' : 'audio/ogg',  'plist':'text/xml'};http.createServer(function(req, res) {  if (req.method !== 'GET') {    console.log(req.method, req.url);    req.setEncoding("utf8");    req.addListener("data", function (postDataChunk) {      //console.log(postDataChunk);      console.log(querystring.parse(postDataChunk));    });    req.addListener("end", function () {      res.writeHead(400);      res.write('GET Only.');      res.end();    });    return;  }  if (req.url === '/favicon.ico') {    console.log(req.headers);    res.write('');    res.end();    return;  }  var request_time = process.hrtime()[1];  var filename = decodeURIComponent(path.join(rootpath, url.parse(req.url).pathname));  //console.log(req.url, url.parse(req.url), filename, rootpath);  if ('/jsonp' === req.url.slice(0, 6)) {    var callback = url.parse(req.url).search.split('jsonp=')[1];    res.write(callback + '({abc:123})');    res.end();    return;  }  fs.stat(filename,function(err,fstats){    if (err) {      if ('.map' !== req.url.slice(-4)) {        var rurl = url.parse(req.url);        console.log('404', rurl.pathname);        rurl.search && console.log(querystring.parse(rurl.search.slice(1)));      }      res.writeHead(404);      res.write('Not Found');      res.end();      return;    }    if(fstats.isFile() && filename.indexOf(rootpath) == 0){      var ext = path.extname(filename).toLowerCase().slice(1);      console.log("sending file %s ",filename, ext);      res.writeHead(200, {'Content-Type': MIMETYPES[ext] || "application/octet-stream"});      fs.createReadStream(filename).pipe(res);    }else{      res.writeHead(200, {'Content-Type': 'text/html'});      res.write("
