After further test verification, the "getQuery" for chinese is fine 
but special characters like "%23" that will decode to "#".  the 
"getRawQuery" is opposite. 


maybe use "uribuilder.replaceParam" is better, but the "NettyHttpClientPlugin" 
can not support this.


I think if combining parameters manually is an option.

Hi，
When arguments contain special characters, the original "DividePlugin" 
implementation uses "getQuery" which decode the arguments("decodeQuery" in 
picture), to escape those special characters. 


eg: GET http://localhost:9195/http/test/divide/raw?name=divide&amp;address=%23


see "getquery.png"


The result: see "getquery-ret.png"


But the "getRawQuery" will use the origin arguments("query" in picture).


the result: see "getrawquery-ret.png"




So if the arguments contain special characters, "getRawQuery" is better choice. 


The other way, user can encode arguments by self.
