英文:
Preview of single page\slide in sharepoint document with Microsoft Graph Api
问题
在 SharePoint 中，借助 Microsoft Graph API，可以生成完整文件（如 docx、pptx）的预览。但是否有可能获取文档中有多少页/幻灯片的数据，并仅生成到单个页/幻灯片的预览链接（不一定是第一页，而是任何一页，否则我可以使用缩略图）？
英文:
In sharepoint with help of Microsoft Graph Api it's possible to generate preview of full file (like docx, pptx) https://learn.microsoft.com/en-us/graph/api/driveitem-preview?view=graph-rest-1.0
But is there is a possibility to get data about how many pages\slides in document and generate preview link only to a single page\slide (not exactly to 1st, but to any, otherwise I could use thumbnails)?

pptx文档的属性应包含内容部分的Slides属性。您可以通过使用Properties方法的REST API调用检索该值。
以下是这种请求的示例（在Power Automate云流中）。
英文:
The doc properties of a pptx should contain a Slides property in the Content section. You could retrieve that value via a REST API call which uses the Properties method.
Below is an example of such a request (in a Power Automate cloud flow).
