1. RFC2396Standard

Including HTML 4.01 section 17.13.4, and also RFC 1866 (which is supercededby the website HTML recommendations).

When the contexttype of a form is [x-www-form-urlencoded], the key/value pairs in the form are encoded, the spaces are escaped to +, and the other characters are processed in%hh form according to the [RFC1738] standard.

2. Js UrlEncode

JS to encode the text involves 3 functions: Escape,encodeuri,encodeuricomponent, the corresponding 3 decoding function: unescape,decodeuri,decodeuricomponent

Escape does not encode characters with 69: *,+,-,.,/,@,_,0-9,a-z,a-z

encodeURI does not encode 82 characters:!,#,$,&, ', (,), *,+,,,-,.,/,:,;,=,?,@,_,~,0-9,a-z,a-z

encodeURIComponent does not encode 71 characters:!, ', (,), *,-,.,_,~,0-9,a-z,a-z

3. The solution::

 s =org.Tuckey.Web.Filters.Urlrewrite.Utils.Urlencoder.Encodepathparam("a B", "Utf-8");//a%20%20b

Manual Replace space to%20

Or

used when URL parsing is received

Urldecoder . Decode ("a++b%20c")) ; //a b c
