怎么了?
似乎它在内部生成了一个下载链接(.../_ layouts/15/download.aspx?UniqueId = ...)，该链接适用于用户名/pwd令牌，但不适用于仅应用"令牌
it seems that internally it generates a download link (.../_layouts/15/download.aspx?UniqueId=...) that works with username / pwd token, but does not work with "app only" token
我还有另一个Office 365订阅，该订阅可以使用仅应用程序"令牌.另一个订阅有一个自定义域，但是我看不到其他配置差异(都将LegacyAuthProtocolsEnabled属性设置为true，相同的共享选项...)
I have another office 365 subscription that works with "app only" token. The other subscription have a custom domain, but I can not see other configuration differences (both have LegacyAuthProtocolsEnabled property set to true, same sharing options...)
:似乎我在星期五测试的示例现在可以正常工作！
It seems that the example I was testing on friday now works!!
推荐答案
该错误于上周三出现，并传播给越来越多的租户.似乎由Graph API/Sharepoint API生成的临时令牌无效.这会影响:
This bug appeared wednesday last week, and is spreading to more and more of our tenants. It appears that temporary tokens generated by the Graph API/Sharepoint API are invalid. This affects:
- 块状文件上传，因为您接收到一个带有临时令牌的URL
- @ microsoft.graph.downloadUrl，因为它包含一个临时令牌
- 内容下载，因为它使用与@ microsoft.graph.downloadUrl完全相同的URL
请尽快解决此问题，因为我的应用程序瘫痪并且客户很生气
Please fix this ASAP, as my application is cripled and the customers are angry
I created a post here too, but no response: Temporary tokens issued by graph api is invalid since wednesday
Also this bug appeared wednesday: Unable to set fileSystemInfo.lastModifiedDateTime on files on Sharepoint Online for some users since wednesday
