我正在尝试将电子表格文件从我的云端硬盘下载到我的计算机上。 我能够成功地进行身份验证,获取文件列表,甚至成功获取元数据。 但当我尝试下载文件时,出现以下错误:
downloading file starts
An error occurred: <HttpError 400 when requesting https://www.googleapis.com/dri
ve/v2/files/1vJetI_p8YEYiKvPVl0LtXGS5uIAx1eRGUupsXoh7UbI?alt=media returned "The
specified file does not support the requested alternate representation.">
downloading file ends
我在stackoverflow上没有找到任何相关的问题或疑问,而且stackoverflow上提供的其他方法和解决方案已经过时。这些方法已被Google弃用。
以下是我用于下载文件的代码:
