Adding `delete` as HTTP method for http_json_read_data

EricGT · May 17, 2023, 4:31pm

Currently http_read_json/2,3 and http_read_json_dict/2,3 does not allow for delete as a valid HTTP method,

SWI-Prolog/packages-http/blob/3040c654f8f8f889084818e6359b8b01340bba4e/http_json.pl#L284-L299


      
          request_to_json(Request, JSON, Options) :-
              option(method(Method), Request),
              option(content_type(Type), Request),
              (   data_method(Method)
              ->  true
              ;   domain_error(method, Method)
              ),
              (   is_json_content_type(Type)
              ->  true
              ;   domain_error(mimetype, Type)
              ),
              http_read_data(Request, JSON, Options).
          
          data_method(post).
          data_method(put).
          data_method(patch).

The documentation notes

domain_error(method, Method) if the request method is not a POST , PUT or PATCH .

Can delete be added for the predicate data_method/1?

For a 3rd party API where delete would be useful

EDIT May 19, 2023

May not need this if SWI-Prolog OpenAPI (Swagger) interface works.
