title: How to handle JSON body using Tornado w/ python3
body: <p>Tornado 4.5.2 using Python3 represents the request body as a byte object instead of a native dictionary.  This presents a problem for methods like <code>RequestHandler.get_body_argument()</code> which will not access the field correctly.  </p>
  
  <p>My question is how to correctly have tornado parse these bodies into more useable dictionaries so the standard library will work.  I've looked throughout tornado's documentation and there's next to nothing on even the existence of this problem.  </p>
  
  <p>Am I missing something here or will I need to re-implement those methods myself? </p>
