参考cnodejs.org上面的静态服务器例子，写了下面的一个nodejs静态服务器例子，里面包含cache,压缩，贴代码如下：
/**
* 静态文件服务器测试例子
* User: xuwm
* Date: 13-5-17
* Time: 上午8:38
* To change this template use File | Settings | File Templates.
*/
var port=3333;
var http = require("http");
var url = require("url");
var fs = require("fs");
var path = require("path");
var mime = require("./mime").types;
var config = require("./config");
var zlib = require("zlib");
//创建http服务端
var server=http.createServer(function(request,response){
var obj= url.parse(request.url);
response.setHeader("Server","Node/V8");
console.log(obj);
var pathname=obj.pathname;
if(pathname.slice(-1)==="/"){
pathname=pathname+config.Welcome.file; //默认取当前默认下的index.html
}
var realPath = path.join("assets", path.normalize(pathname.replace(/../g, "")));
console.log(realPath) ;
var pathHandle=function(realPath){
//用fs.stat方法获取文件
fs.stat(realPath,function(err,stats){
if(err){
response.writeHead(404,"not found",{'Content-Type':'text/plain'});
response.write("the request "+realPath+" is not found");
response.end();
}else{
if(stats.isDirectory()){
}else{
var ext = path.extname(realPath);
ext = ext ? ext.slice(1) : 'unknown';
var contentType = mime[ext] || "text/plain";
response.setHeader("Content-Type", contentType);
var lastModified = stats.mtime.toUTCString();
var ifModifiedSince = "If-Modified-Since".toLowerCase();
response.setHeader("Last-Modified", lastModified);
if (ext.match(config.Expires.fileMatch)) {
var expires = new Date();
expires.setTime(expires.getTime() + config.Expires.maxAge * 1000);
response.setHeader("Expires", expires.toUTCString());
response.setHeader("Cache-Control", "max-age=" + config.Expires.maxAge);
}
if (request.headers[ifModifiedSince] && lastModified == request.headers[ifModifiedSince]) {
console.log("从浏览器cache里取")
response.writeHead(304, "Not Modified");
response.end();
} else {
var raw = fs.createReadStream(realPath);
var acceptEncoding = request.headers['accept-encoding'] || "";
var matched = ext.match(config.Compress.match);
if (matched && acceptEncoding.match(/bgzipb/)) {
response.writeHead(200, "Ok", {'Content-Encoding': 'gzip'});
raw.pipe(zlib.createGzip()).pipe(response);
} else if (matched && acceptEncoding.match(/bdeflateb/)) {
response.writeHead(200, "Ok", {'Content-Encoding': 'deflate'});
raw.pipe(zlib.createDeflate()).pipe(response);
} else {
response.writeHead(200, "Ok");
raw.pipe(response);
}
}
}
}
});
}
pathHandle(realPath);
});
server.listen(port);
console.log("http server run in port:"+port);
首先需要在JS文件里创建一个assets的文件夹，里面放入你要浏览的静态文件，比如，index.html,demo.js等。
运行方式为：在命令行里切换到上面的JS的文件目录，然后输入 node JS文件名
浏览器内输入http://localhost:3333/就会看到效果。
--补上上面代码里缺少的两个模块
