nodejs write raw image data to jpeg file?

Question

I am getting data from a get request. The data (in the body of the response) looks something like this:

... ÿÀ���\"�ÿÄ��������������ÿÄ�N��!1\"AQa2q¡#BR±ð3brS²ÁÂÑ         


        

Answer 1

A slightly shorter version, which uses Stream.pipe:

var http = require('http'),
    fs = require('fs'),
    imgSource = 'http://upload.wikimedia.org/wikipedia/commons/1/15/Jagdschloss_Granitz_4.jpg';

http.get(imgSource, function(res) {
  res.pipe(fs.createWriteStream('wiki.jpg'));
});
