Nice. A minor HTTP protocol glitch though, as there's no self.end_headers() so the response is malformed when served to picky clients (haproxy). ;)

👍

Thanks a lot for the work! I did two adjustments in my fork (at [0]):

• since python 3.3 you need to call self.end_headers() explicitly
• the getheaders semantics has changed and request_headers.get("Content-Length") seems more appropriate
• BaseHTTPServer was replaced by http.server in newer python versions
• My printing statements are more explicit.

Awesome work!!

In Python3.6, keep do this:

self.send_response(200)
self.end_headers()
 self.wfile.write(json.dumps(j_body).encode())

or maybe client cannot get the status code. I have met this problem, so I mark it.

Thank you so much for providing this solution! Saved me what was likely an hour at work to figure out how to do this!
