File downloaded on windows have no extension

[pdavid0]

Not tested on UNIX, but on Windows 8.1 /download returns a file named 'download'.

By adding correct headers I download a more comprehensible file : 'd411b07f-ef8c-437d-910e-b4b48db8e878.mp4'

  download: function (req, res) {
    var path = '.tmp\\uploads\\'+req.param('path');
    console.log(path);
    var mime = require('mime');
    var mimetype = mime.lookup(path);

    res.setHeader('Content-disposition', 'attachment; filename=' + path);
    res.setHeader('Content-type', mimetype);

    require('fs').createReadStream(path)
    .on('error', function (err) {
      return res.serverError(err);
    })
    .pipe(res);
  }
};

Edit : removing "Content-disposition" streams the file to the browser.
