我在任务队列中有一个 Google App Engine 任务，对我的应用最近上传到 Google Drive 帐户的文件和通过调整原始文件大小创建的新文件执行以下四个步骤。

1- file = service.files().get(fileId=googleDriveFileId).execute()

2- resizedImage = resizeImage(theImage,currentWidth,currentHeight,135,90);
   newImage = putGoogleDriveFile(user,resizedImage,imageName,'image/jpeg',None,"image")

3- service.permissions().insert(fileId=file_id, body=new_permission).execute()

4- service.files().delete(fileId=googleDriveFileId).execute()

所有步骤都有效，所有文件都在它们应该具有正确权限的位置，等等。

但是，我的日志文件显示每一步都刷新了 access_token。

这是我应该期待的吗？在我看来，在一个循环中运行的四个操作的一个 access_token 就足够了。

谢谢，克里斯

一个典型的 access_token 持续一小时。我的猜测是每个请求仍在使用过期的令牌而不是闪亮的新令牌。
