I am trying to upload a photo via a POST request with the request

I am trying to upload a photo via a POST request with the request module

According to the readme I should just be able to do this

var r = request.post("http://posttestserver.com/post.php", requestCallback)
var form = r.form()
form.append("folder_id", "0");
form.append("filename", fs.createReadStream(path.join(__dirname, "image.png")));

function requestCallback(err, res, body) {
    console.log(body);
}

The problem is, this doesn’t work. I get a reply from the test server saying it dumped 0 post variables.

I have confirmed that the server is in working condition with this little html page

<html>
    <body>
        <form action="http://posttestserver.com/post.php?dir=example" method="post" enctype="multipart/form-data">
            File: <input type="file" name="submitted">
            <input type="hidden" name="someParam" value="someValue"/>
            <input type="submit" value="send">
        </form>
    </body>
</html>

So the question is, what am I doing wrong with the request module? Is there a better way to send multipart/form-data with node?

    After some more research, I decided to use the restler module. It makes the multipart upload really easy.

    fs.stat("image.jpg", function(err, stats) {
    restler.post("http://posttestserver.com/post.php", {
        multipart: true,
        data: {
            "folder_id": "0",
            "filename": restler.file("image.jpg", null, stats.size, null, "image/jpg")
        }
    }).on("complete", function(data) {
        console.log(data);
    });
});
