Blob/Stream/Buffer request support?

How to request with a binary body directly, I cannot find this in document?

For example:

// node stream
const file = fs.createReadStream('./example.png')
// node buffer
const file = fs.readFileSync('./example.png')
// browser
const file = document.querySelector('input[type=file]').files[0]

request
  .post('/proxy')
  .set('Content-Type', 'application/octet-stream')
  .send(file)
  // attach a blob/stream/buffer directly to request body like node node core http module
  .end()

Thanks. I couldn’t get attach() to work, and actually ended up using send(), which to my surprise worked fine

The buffer was created with:

const buffer = Buffer.from(base64Data, 'base64'); 
const response = await request
        .post('<URL>')
        .send(buffer)
        .set('SubscriptionKey', '<XYZ>')
        .set('Content-Type', 'application/octet-stream')
        .set('Accept', 'application/json');

how did you used ‘application/octet-stream’ to uploading?
