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。

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).
