Python tornado AsyncHTTPClient 599

Question

I try to send async PUT request with AsyncHTTPClient, but tornado return HTTP 599 error before request_timeout.

Answer 1

I fix this problem by write body="" to request:

 req = tornado.httpclient.HTTPRequest(url,
                                     method="PUT",
                                     request_timeout=10,
                                     headers=headers,
                                     **body=""**)

Tornado can't send put request with empty body.
