尝试通过API（v3）在Google云端硬盘上创建文件夹时权限不足

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，并且创建了一个脚本，该脚本可获取每日报告，并希望通过API创建一个文件夹，并将这些文件每天上传到该文件夹。

要进行设置，我已经按照文档的快速入门指南创建了一个项目。我的设置看上去与该样板基本相同，只是其读取了Drive中文件的功能。但是，当尝试使用docs中给出的示例进行上传时，出现错误：Insufficient

Permission。

浏览项目界面中的权限，有很多角色可供选择。目前，我已将我的项目分配为文件夹管理员（以及其他几个角色），这应该

给我权限，但仍然遇到此错误。也许我需要重新生成client_secret.json文件以反映我更新的权限，但是我该怎么做？我已经在谷歌上搜索并在界面上闲逛了一段时间，但是看不到重新生成此文件的方法。

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-只是为了看到它可以工作：

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);
        }
      });
    }

任何帮助表示赞赏。

更新错误：

回答：

我认为您的脚本有效。那么您可以再次确认以下几点吗？

关于范围。
- 在快速入门中，默认范围为var SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];。但是为了使用drive.files.create，https://www.googleapis.com/auth/drive必须将其添加到范围。
- 如果您修改了范围，请删除的文件drive-nodejs-quickstart.json。并运行脚本。这样，将运行授权，并将添加的作用域反映到刷新令牌和访问令牌。

关于googleapis的版本
- 最近，据报道v27.0.0，v26.0.1和v25.0.0的googleapi存在一些错误。因此，请确认您的版本，以防万一。我使用v24.0.0。

是否在API控制台上启用了Drive API。
- 关于这一点，我认为从您的问题来看，您可能已经启用了它。

如果这些对您没有用，对不起。
