当解析zh_desc的中文值时，显示为控制，而解析code、en_desc是对的。
var JSon_Root :TlkJSONobject; var Rlt_Str Rlt_Str :String;
Rlt_Str :='{"error_response":{"code":"22","zh_desc":"授权者不是商家","en_desc":"the franchisor not businessmen"}}'
JSon :=TlkJSON.ParseText(Rlt_Str) as TlkJSONobject;
if JSon.Field['error_response'] <>nil then begin
JSon_Root :=JSon.Field['error_response'] as TlkJSONobject;
with JSon_Root do begin
ShowMessage(getString('code'), ); //22
ShowMessage(getString('en_desc')); //the franchisor not businessmen
ShowMessage(Field['zh_desc'].Value); //为什么是空值，而不是授权者不是商家
end;
end;
