        // 登陆

        Response res = Jsoup.connect("http://"+SITE+":"+PORT+"/casreport/Login")

                        .referrer("http://"+SITE+":"+PORT+"/casreport/viewList.do")

                        .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0)")

                        .data("encryption", "false", "username", "test", "test", "0000")

                        .method(Method.POST)

                        .timeout(5000000)

                        .execute();



        Map<String, String> cookies = res.cookies();



        cookies = res.cookies();

        System.out.println(cookies);



        // 访问列表

        Response res1 = Jsoup.connect("http://"+SITE+":"+PORT+"/casreport/viewList.do")

                        .referrer("http://"+SITE+":"+PORT+"/casreport/viewList.do")

                        .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0)")

                        .data("beginDate", "2017-05-02", "endDate", "2017-06-02") //, "JSESSIONID", cookies.get("JSESSIONID")

                        .cookie("JSESSIONID", cookies.get("JSESSIONID"))

                        .method(Method.POST)//.cookies(cookies)

                        .execute();

        

        Map<String, String> cookies1 = res1.cookies();

        System.out.println(cookies1);

        System.out.println("============================================================================");

输出结果如下：
cookies:{JSESSIONID=HX6nZ0jb2nMTGzVlJYyfLKwHGyKFvSZSnhb2hQTm6pxppnvXmRTL!126911448}
cookies1:{}
============================================================================

请问各位大神，为什么cookies有值，cookies1没有值了呀。正常用网页登陆后跳转到一个首页，是使用的frameset，不知道和这个有没有关系。
