这是我运行节点js文件系统的代码

    var http = require('http');
    var fs = require('fs');
    http.createServer(function (req, res) {
      //Open a file on the server and return its content:
      fs.readFile('demofile1.html', function(err, data) {
        res.writeHead(200, {'Content-Type': 'text/html'});
        res.write(data);
        return res.end();
     
 });
    }).listen(3000);
