尝试通过 API（v3）在 Google Drive 上创建文件夹时权限不足

Question

我正在尝试通过 API 在我的 Google Drive 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 创建一个文件夹并将这些文件每天上传到它。

为了进行设置，我根据文档的quick start guide 创建了一个项目。我的设置看起来与样板基本相同，但减去了读取 Drive 中文件的功能。但是，在尝试上传 using the example given in the docs 时出现错误：Insufficient Permission。

通过项目界面中的权限，有一堆角色可供选择。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），应该授予我权限，但我仍然遇到此错误。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，但我该怎么做呢？我一直在谷歌搜索和浏览界面很长一段时间，但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 - 只是为了看看它是否有效：

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。

更新错误：

我认为您的脚本有效。那么您能否再次确认以下几点？

1. 关于范围。
   • 在快速入门中，默认范围是 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添加到作用域中。
   • 如果您修改了范围，请删除drive-nodejs-quickstart.json 的文件。并运行脚本。这样，授权就会运行，并且添加的范围会反映到刷新令牌和访问令牌中。
2. 关于googleapis的版本
   • 最近有报道称，v27.0.0、v26.0.1、v25.0.0的googleapis存在一些bug。因此，请确认您的版本以防万一。我使用 v24.0.0。
3. 是否在 API 控制台启用了 Drive API。
   • 关于这个，我认为从你的问题来看，你可能已经启用了。

如果这些对你没有用，我很抱歉。
