Wordpress oauth2令牌在从浏览器中检查时有效，但如果从Android应用程序调用，则响应为＆＃34; Oauth2令牌无效＆＃34;

Question

我正在尝试使用Android应用在我的Wordpress博客上发帖。 我得到了回应 {"Content":"{\"error\":\"invalid_token\",\"message\":\"The OAuth2 token is invalid.\"}","Message":"Bad Request","Length":-1,"Type":"application\/json"}

但是当我在浏览器中使用相同的令牌来获取gettin令牌信息时，响应是

{"client_id":"51388","user_id":"114830097","blog_id":"121719179","scope":""}

表示令牌对使用有效。所以我觉得我的代码可能有些问题。
