How to upload file using restify

Question

I'm trying to upload image file to Rest server(Confluence to be more specific) using Restify module but getting Assertion error. I'm not sure if I'm using right approach for file upload to REST server. Could anyone point me to the right direction?

This is my attempt -

var restify = require('restify');
var header = {'Authorization': 'Basic xxxxx', 'content-type': 'multipart/form-data'};
var client = restify.createJsonClient({
   url: 'http://www.testsite.com',
   version: '*',
   headers: header
});
var image = "c:\\Users\\abc\\Documents\\bbb.jpg";           
var fileStream = fs.createReadStream(image);
var stat = fs.statSync(image);
var size = stat["size"];
var param = "?pageId=123&filename=mynewimage&mimeType=image%2Fjpeg&size=" + size;       
fileStream.pipe(
    client.post("/plugins/drag-and-drop/upload.action"+param, function(err, req, res, obj) {
        if (err) {
            return err;
        }

    })
);  

UPDATE:

This is an assertion error I'm getting assert.js:86

throw new assert.AssertionError({
        ^
AssertionError: body

To send multipart/form-data, you will have to use a library other than restify because it doesn't support that Content-Type.

You could use request which does have support for multipart/form-data http requests built-in.
