內容詳盡的說明文件
getAs(contentType)
將此物件內的資料傳回為轉換為指定內容類型的 Blob。這個方法會在檔案名稱中加入適當的副檔名，例如「myfile.pdf」。不過，這會假設檔案名稱中最後一個句點 (如有) 後面的部分是應取代的現有副檔名。因此，「ShoppingList.12.25.2014」會變成「ShoppingList.12.25.pdf」。
如要查看轉換的每日配額，請參閱「Google 服務的配額」。新建立的 Google Workspace 網域可能會暫時受到較嚴格的配額限制。
參數
| 名稱 | 類型 | 說明 |
contentType | String | 要轉換的 MIME 類型。對於大多數 Blob 而言，'application/pdf' 是唯一有效的選項。如果是 BMP、GIF、JPEG 或 PNG 格式的圖片，'image/bmp'、'image/gif'、'image/jpeg' 或 'image/png' 皆可用。如果是 Google 文件，'text/markdown' 也是有效的。 |

However, it\nassumes that the part of the filename that follows the last period (if any) is an existing\nextension that should be replaced. Consequently, \"ShoppingList.12.25.2014\" becomes\n\"ShoppingList.12.25.pdf\".\n\nTo view the daily quotas for conversions, see [Quotas for Google\nServices](https://developers.google.com/apps-script/guides/services/quotas).
