解决方案

不确定如何获取访问令牌，假设您在线使用SharePoint，您可以构建SharePoint加载项或使用用于访问SharePoint数据的加载项令牌。

您可以查看以下youtu.be视频。

你可以查看我的也可以在下面的线程中测试演示。

我建议你用英语解释你的问题，以便我们更清楚地了解你。

解决方案

Hi,

Not sure how you get the access token, suppose you’re using SharePoint online, you could build SharePoint add-in or use add-in token to access SharePoint data.

You could check below youtu.be video.

You could check my test demo in below thread also.

I would suggest you explain your issue in english in furture so we could understand you more clearly.
