impossible to execute POST using body

[lsimone]

I want to send POST requests using the request body and the Content-Type: application/json header.
Restful.js always populate the request form and the http client request executes the request as a application/x-www-form-urlencoded so I receive an error. It seems impossible to cover this use case with restful.js.

In order to solve this issue, I temporally modified the code in my fork, but I guess that a parameter to choose if using body or form would be better.
Is that a viable solution?
