我如何阅读和定位我需要在jsoup中输入登录信息的位置才能访问VPN上的网络？我对所涉及的步骤/主题的解释以及使用java的编程方法感兴趣（基本上如何使用jsoup在java中编写代码） . 注意：对于所有重定向，我很难理解在jsoup-login中发生了什么以及如何/何时/在哪里编码 .
到目前为止，这是我的工作流程：
我有一个目标页面，如下所示
[debug] status code 302 : https://centrale.landingnetwork.com/gp/stores/www.landingnetwork.com/gp/home/
相应的 Headers ：

当我在java / jsoup中导航到这个URL时，我得到了各种重定向 . 这是我的重定向的踪迹:(接下来的顺序）
[debug] status code 302 : https://centrale.landingnetwork.com/gp/stores/www.landingnetwork.com/gp/signin/gi-signin.html/123-1234567-1234567?ie=UTF8&landat=%2Fgp%2Fstores%2Fwww.landingnetwork.com%2Fgp%2Fhome%2F123-1234567-1234567&ort=1122334455.98765&rrt=1112223334.12121

以及链接路径中的下一个链接：

相应的 Headers ：

编辑：确定nonce值不需要是显示的确切值，我编辑了一个通用值 . &rrt= 和 &ort= 值的想法相同 . （如果这些对我的任务有重要意义，请解释） .
edit2：在每个链接的相应 Headers 中添加 .
edit2：此外，这是登录表单的 action= 值的值 .
/login?sif_profile=gi_profile_1&clientId=Centrale-prod-na&nonce=867:5309:867:5309:867:5309:867:5309:867:53099&redirect_uri=https://centrale.landingnetwork.com:443/gp/stores/www.landingnetwork.com/gp/signin/gi-landat.html/123-1234567-1234567?landat=/gp/stores/www.landingnetwork.com/gp/home/123-1234567-1234567
现在，我在网络方面没有超级大背景，但如果解释得很好/彻底，我肯定可以跟进 .
我的问题：当我浏览重定向时，我不知道为什么我的用户名/密码的表单发布代码不起作用 .
edit3：以下是导航期间的请求标头信息，如Chrome网络标签中所示：

到目前为止，这是我的代码，（两个类）;

当我打印出 Headers 时，它们看起来相对简单，唯一可能让我感到惊讶的是， 'X-REQUEST-ID1' / 'X-REQUEST-ID2' Headers ，设置cookie会话ID和位置 . 但是我没有在哪里尝试使用jsoup与多个网页上的数据进行交互 .
To reiterate my question ：如何使用java / jsoup以实用方式登录我的网站？如果有人愿意花时间，那么详细/例子/最终代码的详尽解释将是一个光荣的教训！
干杯
