This decorator implies the following changes: Parameters: HTTPServerRequest.body follow_redirects=None, max_redirects=None, user_agent=None, use_gzip=None, network_interface=None, streaming_callback=None, header_callback=None, prepare_curl_callback=None, proxy_host=None, proxy_port=None request. curl_httpclient only; see not below. streaming_callback (callable [https://docs.python.org/3.5/library/functions.html#callable]) – If set, streaming_callback will be run with each chunk of data

decorator. tornado.web.stream_request_body(cls) Apply to RequestHandler subclasses to enable streaming body support. This decorator implies the following changes: • HTTPServerRequest.body is undefined interface to use for request. curl_httpclient only; see note below. • streaming_callback (collections.abc.Callable) – If set, streaming_callback will be run with each chunk of data as it is received, and HTTPResponse.headers will be empty in the final response. This is most useful in conjunction with streaming_callback, because it’s the only way to get access to header data while the request is in progress
