This looks like a Cross-Origin Resource Sharing (CORS) preflight request issue.

I would recommend adding a do_OPTIONS method to your class:

def do_OPTIONS(self):           
    self.send_response(200, "ok")       
    self.send_header('Access-Control-Allow-Origin', '*')                
    self.send_header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS')
    self.send_header("Access-Control-Allow-Headers", "X-Requested-With")

This will tell your browser that the POST request has Access-Control.
