雲端硬碟進階服務可讓您在 Apps Script 中使用 Google Drive API。這個 API 與 Apps Script 的內建雲端硬碟服務非常相似,可讓指令碼在 Google 雲端硬碟中建立、尋找及修改檔案和資料夾。在大多數情況下,內建服務的使用方式較為簡單,但這項進階服務提供一些額外功能,包括存取自訂檔案屬性,以及檔案和資料夾的修訂版本。

如要進一步瞭解這項服務,請參閱 Google Drive API 的參考文件。與 Apps Script 中的所有進階服務一樣,進階 Google 雲端硬碟服務會使用與公開 API 相同的物件、方法和參數。詳情請參閱「如何判斷方法簽章」。

列出資料夾
以下程式碼範例說明如何列出使用者 Google 雲端硬碟中的頂層資料夾。請注意,您必須使用網頁權杖才能存取完整的結果清單。
