I want to get url2 from url1 by code..Then decode url2 to can open in web How must I do?

Answer 1

i think your url1 is not a valid url. Can not decode to a valid url neither by utf8 nor GB

Answer 2

You URL1 is not a valid URL. URLDecoder.decode(string url) is deprecated. You should use URLDecode.decode(String url, String enc) where enc is the character encoding.

Also % must be encoded as %25

public class DecodeTest
{
   public static void main(String[] args)
   {

      String url="http://bitake.com/params/?attribute=3";

      String url1="http://search.bitake.com/params/?attr=48%25e6%2599%2582%25e9%2596%2593%25e3%2582%25";

      try
      {
         System.out.println(URLDecoder.decode(url,"UTF-8"));
         System.out.println(URLDecoder.decode(url1, "UTF-8"));
      }
      catch (UnsupportedEncodingException e)
      {
         e.printStackTrace();
      }
   }
}
