#delete_param(k) ⇒ Object

Destructively delete a parameter, whether it’s in GET or POST. Returns the value of the deleted parameter.

If the parameter is in both GET and POST, the POST value takes precedence since that’s how #params works.

env['rack.input'] is not touched.

#form_data?Boolean

Determine whether the request body contains form-data by checking the request Content-Type for one of the media-types: “application/x-www-form-urlencoded” or “multipart/form-data”. The list of form-data media types can be modified through the FORM_DATA_MEDIA_TYPES array.

A request body is also assumed to contain form-data when no Content-Type header is provided and the request_method is POST.

Returns:

  • (Boolean)
