An effective solution for passing Chinese parameters to garbled characters in the background using Ajax

If Ajax is used to pass Chinese parameters, if the parameters are not processed, it will become garbled in the background. The following method can be used after testing.

Here we use the jquery. autocomplete plug-in to obtain the data in the input box and upload it to the background as an example:

Use encodeURI to encode Chinese characters twice.
Copy codeThe Code is as follows:
ExtraParams: {q: function () {return encodeURI ($ ('# keyword'). val ()))}}

Decode twice here.
Copy codeThe Code is as follows:
String key = URLDecoder. decode (URLDecoder. decode (q, "UTF-8"), "tuf-8 ");
