使用WPF应用程序使用图连接到Azure AD api

Question

我试图用图来连接到wpf应用程序中的天蓝色AD。身份验证似乎很顺利，我得到一个访问令牌返回。我也可以使用这个令牌来获得关于我自己的基本信息。然而，当我试图从目录要求的东西我得到的错误：

Code":"JWT10315 Signature validation failed. Keys tried:

然后一大堆其他的东西。一切似乎都没问题。该应用程序在Azure中注册。我设置了正确的访问权限。我无能为力。任何人都可以帮助我？我的代码如下。

Answer 1

string url = " https://graph.windows.net/mydomain.com/activities/signinEvents?api-version=beta& `$filter=userPrincipalName eq '[email protected]'";

根据你的描述，你正在访问Azure Active Directory sign-in activity report API。我跟着这个tutorial来检查这个问题。我同时检查了仅限应用程序范围（应用程序作为没有登录用户的服务运行）和委托范围（委托登录用户的权限）与Directory.Read.All范围，我也可以检索用户的信息。

但是，当我通过邮递员使用访问令牌访问登录活动API Endpoint时，我收到响应并提示我将租户升级到Azure AD Premium层，然后选取我的目录并通过激活试用在Azure门户点击“公司品牌推广>免费赠送试用版”。一旦升级，我可以取回登入活动如下：

此外，我遇到了类似的问题如下：

在一般情况下，你可以利用jwt.io解码您的访问令牌并确保相关属性已被正确包含。
