node.js write http response to stream

Question

i'm fetching some binary data over http. My code looks like:

var writeStream = fs.createWriteStream(fileName);
request(url, function(err, res) {
    res.socket.pipe(writeStream);
});

now the output file is created but the filesize is 0. The url is correct though, i verified that with wget.

Thanks in advance & best regards

Answer 1

The callback for http.request only supplies one argument, which is a reference to the response of the request. Try

http.request(url, function(res) {
    res.pipe(writeStream);
});

Also note that the ClientResponse implements ReadableStream , so you should use .pipe rather than .socket.pipe .

Answer 2

I'm assuming that here request is from mikeal's request library rather than being an instance of http.request . In that case you can simply do request(url).pipe(writeStream);

Remember that for debugging purposes, you can always pipe to process.stdout .

Answer 3

 var readStream = fs.createReadStream(fileName); request(url, function(err, res) { readStream.pipe(res); readStream.on('end', function() { //res.end({"status":"Completed"}); }); });
