我正在尝试通过API在Google云端硬盘上创建一个文件夹。我正在使用Node，并创建了一个脚本来获取每日报告，并希望通过API创建一个文件夹并每天将这些文件上传到它。
要进行设置，我已根据文档quick start guide创建了一个项目。我的设置看起来基本上与样板文件相同，减去了读取Drive中文件的功能。但是，在尝试上传using the example given in the docs时，我收到错误：Insufficient Permission。
通过项目界面中的权限，有许多角色可供选择。目前我已将我的项目指定为文件夹管理员（以及其他几个角色），应该给我权限但我仍然面临此错误。也许我需要重新生成我的client_secret.json文件以反映我更新的权限，但我该怎么做？我一直在谷歌上搜索和浏览界面很长一段时间，但看不到再生这个文件的方法。
我用来创建文件夹的代码看起来像这样，非常接近文档中给出的样板 - 只是为了看它的工作原理：
const drive = google.drive('v3')
function createFolder (auth) {
console.log('auth:', auth)
const fileMetadata = {
'name': 'daily-report',
'mimeType': 'application/vnd.google-apps.folder',
'parents': ['1P924MEzU_1VoL6OOvWPHSo6vb1u9u0a9'],
}
drive.files.create({
auth: auth,
resource: fileMetadata,
fields: 'id'
}, function (err, file) {
if (err) {
// Handle error
console.error(err.message);
} else {
console.log('Folder Id: ', file.id);
}
});
}
感谢任何帮助。

我认为你的脚本有效。那么你能再次确认以下几点吗？
var SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];。但是，为了使用drive.files.create，需要将https://www.googleapis.com/auth/drive添加到范围中。drive-nodejs-quickstart.json的文件。并运行脚本。这样，就会运行授权，并将添加的范围反映到刷新令牌和访问令牌。如果这些对你没用，我很抱歉。
