encode_www_form

Generate URL-encoded form data from given enum.

This generates application/x-www-form-urlencoded data defined in HTML5 from given an Enumerable object.

This internally uses URI.encode_www_form_component(str).

This doesn’t convert encodings of give items, so convert them before call this method if you want to send data as other than original encoding or mixed encoding data. (strings which is encoded in HTML5 ASCII incompatible encoding is converted to UTF-8)

This doesn’t treat files. When you send a file, use multipart/form-data.

This refers http://www.w3.org/TR/html5/forms.html#url-encoded-form-data
