'Dictionary-like object representing the POST body.
Most values are encoded strings, or unicode strings when
``charset`` is set. There may also be FieldStorage objects
representing file uploads. If this is not a POST request, or the
body is not encoded fields (e.g., an XMLRPC request) then this
will be empty.
This will consume wsgi.input when first accessed if applicable,
but the raw version will be put in
environ[\'paste.parsed_formvars\'].
Returns a ``MultiDict`` container or a ``UnicodeMultiDict`` when
``charset`` is set.'

def POST(self):

    params = self._POST()
    if self.charset:
        params = UnicodeMultiDict(params, encoding=self.charset, errors=self.errors, decode_keys=self.decode_param_names)
    return params
