Node.js Download File Using Content Disposition as Filename

Question

I\'m using the Request module to download files, but I\'m not quite sure how to pipe the response to an output stream when the filename must come from the \'Content-Disposition\

Answer 1

I'm reqesting a image from yahoo and it isn't using the content-disposition header but I am extracting the date and content-type headers to construct a filename. This seems close enough to what you're trying to do...

var request = require('request'),
fs = require('fs');

var url2 = 'http://l4.yimg.com/nn/fp/rsz/112113/images/smush/aaroncarter_635x250_1385060042.jpg';

var r = request(url2);

r.on('response',  function (res) {
  res.pipe(fs.createWriteStream('./' + res.headers.date + '.' + res.headers['content-type'].split('/')[1]));

});

Ignore my image choice please :)
