怎么了?

它似乎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/密码令牌，但不适用于仅限应用"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

我有另一个使用仅限应用"令牌的 Office 365 订阅.另一个订阅有一个自定义域，但我看不到其他配置差异(两者都将 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...)

看来我周五测试的示例现在可以工作了！！

It seems that the example I was testing on friday now works!!

推荐答案

这个错误在上周星期三出现，并且正在蔓延到我们越来越多的租户.Graph API/Sharepoint API 生成的临时令牌似乎无效.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:

• 分块文件上传，当您收到一个使用临时令牌上传到的网址时
• @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 完全相同的网址

请尽快解决这个问题，因为我的应用程序已瘫痪，客户很生气

Please fix this ASAP, as my application is cripled and the customers are angry

我也在这里创建了一个帖子，但没有回复:临时代币由图 api 自周三起无效

I created a post here too, but no response: Temporary tokens issued by graph api is invalid since wednesday

周三也出现了这个错误:自星期三以来，无法为某些用户在 Sharepoint Online 上的文件设置 fileSystemInfo.lastModifiedDateTime

Also this bug appeared wednesday: Unable to set fileSystemInfo.lastModifiedDateTime on files on Sharepoint Online for some users since wednesday

您在 Mark LeFleur 上找到什么了吗?
