createServer();  function createServer(){      var http = nodeRequire("http");     http.createServer(function(request, response) {          let path = request.url;         response.writeHead(200, {"Content-Type": "text/html"});         let fs = nodeRequire("fs");         let data = fs.readFileSync(app_dir+path);         response.write(data.toString());         response.end();      }).listen(8888);  } 

就像这样，输出一个html文件，跟正常访问一样，不过遇到css、js什么都要自己判断。应该有现成的轮子可用了，推荐一个吧？
