在试图保存凭据时，使用Google Drive API库并使用Java冻结/锁定应用程序
我正在使用Java的Play Framework应用程序中使用Google Drive API库/代码。我在API部分的GCP项目中正确设置了凭据。我仍然在学习这些谷歌库和我使用的代码是如何从我找到的一些帖子中获得的，所以我不明白为什么它会冻结，也不知道如何修复它 我的代码在本地运行应用程序时运行良好（在试图保存凭据时，使用Google Drive API库并使用Java冻结/锁定应用程序,java,playframework,google-drive-api,playframework-2.0,Java,Playframework,Google Drive Api,Playframework 2.0,我正在使用Java的Play Framework应用程序中使用Google Drive API库/代码。我在API部分的GCP项目中正确设置了凭据。我仍然在学习这些谷歌库和我使用的代码是如何从我找到的一些帖子中获得的，所以我不明白为什么它会冻结，也不知道如何修复它 我的代码在本地运行应用程序时运行良好（http://localhost:9000）。但是，当我在服务器上运行时，当它试图保存凭据时，它会冻结/锁定-它从不返回错误或消息。我已经等了15分钟没有回应。以下是代码行： credential
