Sending an image in the body of a POST request and get json returned

Building a straightforward webcam image capture application but the server requirements have changed. Now I am being asked to send the image in the body of a post request and to listen for a json response.

ie to

http://localhost:8008/api/recognize

Assuming the image exists in the following directory

/home/user/webcam/

how might I accomplish this?
