Chinese parameter garbled characters in the url of the Extjs4.2 ajax request

There is a need to input Chinese parameters in the url today. garbled characters may occur when the results are obtained in the background. I suspect it may be a encoding problem. I searched the information online and tried several methods, it is found that there is a feasible record here for reference.

The url is encoded twice with encodeURI:

Ext. Ajax. request ({url: "updateadminuser. do? "+ Userid +" & uname = "+ encodeURI (uname), success: function (response) {store. load ();}});

Then perform Decoding in the servlet:

String uname = java.net. URLDecoder. decode (request. getParameter ("uname"), "UTF-8 ");

You can!
