为了从我的驱动器下载一个.mp4文件,开始使用Google Drive API与目标CLI工具,需要创建新的证书。
然后,当下载属于一个用户的文件,只发送给我的链接使用谷歌驱动器API。

while done is False:

我得到了以下错误信息
File "C:\Users\tiago\Anaconda3\lib\site-packages\googleapiclient\http.py", line 749, in next_chunk
raise HttpError(resp, content, uri=self._uri)
HttpError: <HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/1ZVFrwYaLClNrIk6TkshJZamHSS-59LLR?alt=media returned "The user has not granted the app 682654872192 read access to the file 1ZVFrwYaLClNrIk6TkshJZamHSS-59LLR.">
这并不是什么新鲜事(尽管它是 可能是一个误导性的错误信息),是 在其文件中描述的 作为
解决一个403错误。用户没有授予应用程序{appId}{verb}访问文件{fileId}的权限。
其中规定
当您的应用程序不在文件的 ACL 中时,会发生 appNotAuthorizedToFile 错误。
...
要修复此错误,请执行以下操作之一。
打开Google Drive采集器 并提示用户打开该文件。
指导用户使用您的应用程序打开文件,使用的是 打开 右键菜单。
您还可以检查文件上的isAppAuthorized字段,查看该文件是否由您的应用程序创建或打开。
