问题：
如果用户在网页中闲置几分钟并访问网页中的任何link，系统显示
`{"error_description":"Invalid JWT token. The token is expired."}` instead of word editor embedded in `iframe`
官方文档说的很清楚：
This action allows you to obtain short-lived embeddable URLs for
an item in order to render a temporary preview.
If you want to obtain long-lived embeddable links, use the
createLink API instead.
此端点仅提供一个短暂的可嵌入 URL。
我们可以发现返回的link中有一个access_token(getUrl):
https://tenant-my.sharepoint.com/personal/allenwu_tenant_onmicrosoft_com/_layouts/15/embed.aspx?uniqueId=ef*****c-e100-4dcd-a47c-f9c2c*****88&access_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJ***
如果你在https://jwt.io, you will get the exp claim which means the expiration time of the access token. Copy the value of exp and convert it to date in this link: https://timestamp.online/中解码它。然后我们可以看到这个access token的实际生命周期是5分钟左右。
因此用户保持空闲，然后出现 Invalid JWT token. The token is expired. 错误。符合预期。
如果您想获得长期可嵌入links，请按照文档建议使用createLink API。
