Android，Rest api发布错误-访问被拒绝

我是初学者。这是我的第一个Android应用程序。我在从Android向Drupal服务器发布数据时遇到问题。我正在使用RESTAPI

我可以作为Drupal管理员用户登录，我得到会话id、会话名称和令牌。我的问题是发布数据。我认为问题在于发布时的身份验证。我不知道该怎么做那部分

INTERNET和ACCESS_NETWORK_状态都在清单中声明

登录部分（工作）

发布部分，不工作。
在第二个活动中，我想发布一些数据。 这就是我的问题所在。我一直收到拒绝访问的消息。

如何使用result（intent.putExtra（“My_result”，result）-来自登录页面）中的会话id、会话名称或令牌发布内容？这真的是正确的方法吗？如果有更好的办法，请告诉我
