Class UrlEncoded

java.lang.Object

org.eclipse.jetty.util.UrlEncoded

public class UrlEncoded
extends Object

Handles coding of MIME "x-www-form-urlencoded".

This class handles the encoding and decoding for either the query string of a URL or the _content of a POST HTTP request.

Notes

The UTF-8 charset is assumed, unless otherwise defined by either passing a parameter or setting the "org.eclipse.jetty.util.UrlEncoding.charset" System property.

ENCODING

public static final Charset ENCODING

Method Details

encode

public static String encode(MultiMap<String> map,
 Charset charset,
 boolean equalsForNullValue)

Encode MultiMap with % encoding.

Parameters:

map - the map to encode

charset - the charset to use for encoding (uses default encoding if null)

equalsForNullValue - if True, then an '=' is always used, even for parameters without a value. e.g. "blah?a=&b=&c=".

Returns:

the MultiMap as a string encoded with % encodings.
