[semidet,multifile]http:post_data_hook(+Term, +Out, +Options)

Hook to extend the datatypes supported by the post(Data) option of http_open/3. The default implementation supports prolog(Term), sending a Prolog term as application/x-prolog.

[semidet,multifile]http:post_data_hook(+Data, +Out:stream, +HdrExtra)

Hook implementation that allows http_post_data/3 posting JSON objects using one of the forms below.

http_post(URL, json(Term), Reply, Options)
http_post(URL, json(Term, Options), Reply, Options)

If Options are passed, these are handed to json_write/3. In addition, this option is processed:

json_object(As): If As is dict, json_write_dict/3 is used to write the output. This is default if json(Dict) is passed.

To be done: avoid creation of intermediate data using chunked output.
