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±ð3brS²ÁÂÑá$ñCDTst¢³&45dÃÒÿÄ������������ÿÄ�-������!1A"Qa¡ðq±ÁÑ2áÿÚ���?�û."

the response headers look like this:
HTTP/1.1 200 OK

I want to get the body content which is my image data and save it to a name.jpeg
file on the server.
How can I do that? I tried using buffers combined with the fs
module, but I am kind of lost.
Thanks
Here's an example, which downloads http://upload.wikimedia.org/wikipedia/commons/1/15/Jagdschloss_Granitz_4.jpg to name.jpeg
var fs=require('fs');
var http=require('http');
var f=fs.createWriteStream('name.jpeg');
var options={
host:'upload.wikimedia.org',
port:80,
path:'/wikipedia/commons/1/15/Jagdschloss_Granitz_4.jpg'
}
http.get(options,function(res){
res.on('data', function (chunk) {
f.write(chunk);
});
res.on('end',function(){
f.end();
});
});
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'));
});
