Test code

         String address = "HTTPS Web addresses";         // Bypass HTTPS certificate scheme 1        byte [] resultbytes=httpsutil.doget (address);        String result=new  string (resultbytes);        SYSTEM.OUT.PRINTLN (result);             // as long as no exception occurs during the request, the problem of successfully bypassing the HTTPS certificate is explained, and the Red text section is the key in the example above
