Confirmed.  Thanks for observing this case Mike.  Unfortunately, this can't be handled by a simple branch:

if (strcmp (options.MediaType, "application/x-www-form-urlencoded"))
  param = strsplit (varargin{1}, {"=", "&"});

The "backend function" `__restful_service__` requires a Nx2 cell array of key-value string pairs.  WIP.

Octave's webwrite function only allows data to be POSTed in form-encoded key-value pairs. It can't yet be used to send user-defined data such as a XML or JSON blob.

This example should ideally work

options = weboptions ('MediaType', 'text/plain')
response = webwrite ('http://localhost/post', 'This is a test message', options)

and should be the same as

curl -X POST -H 'Content-Type: text/plain' -d 'This is a test message' 'http://localhost/post'

But it instead tries to parse the 'data' argument into key-value pairs and POST as a form anyway.

This is related to the message in weboptions that the MediaType keyword is not yet implemented. If MediaType is not set, then webwrite seems to be working correctly. This is also a Matlab compatibility issue, but since this function is brand new it's fair to consider it a feature request.
