详细文档
getAs(contentType)
将此对象内的数据作为转换为指定内容类型的 blob 返回。此方法会向文件名添加相应的扩展名，例如“myfile.pdf”。不过，它假定文件名最后一个英文句点（如果有）后面的部分是应替换的现有扩展名。因此，“ShoppingList.12.25.2014”会变为“ShoppingList.12.25.pdf”。
如需查看转化每日配额，请参阅 Google 服务的配额。新创建的 Google Workspace 网域可能会暂时受到更严格的配额限制。
参数
| 名称 | 类型 | 说明 |
contentType | String | 要转换到的 MIME 类型。对于大多数 blob，'application/pdf' 是唯一有效的选项。对于 BMP、GIF、JPEG 或 PNG 格式的图片，'image/bmp'、'image/gif'、'image/jpeg' 或 'image/png' 中的任何一种也有效。对于 Google 文档，'text/markdown' 也有效。 |
返回
Blob - 数据（以 blob 的形式）。
getBlob()
以 blob 的形式返回此对象内的数据。
返回
Blob - 数据（以 blob 的形式）。

此网址会标记为请求者的账号，因此知道此网址的任何人都可以有效地以原始请求者的身份访问图片。如果演示文稿的共享设置发生变化，您可能会失去对图片的访问权限。该网址会在短时间后过期。
返回
String

This\nmethod adds the appropriate extension to the filename---for example, \"myfile.pdf\". 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).
