Azure B2C-使用msal获得调用图API的授权
我最近开始与B2C合作。我设法让他们使用MSAL和API与我自己的租户一起工作 现在我想：Azure B2C-使用msal获得调用图API的授权,azure,microsoft-graph-api,azure-ad-b2c,Azure,Microsoft Graph Api,Azure Ad B2c,我最近开始与B2C合作。我设法让他们使用MSAL和API与我自己的租户一起工作 现在我想： 了解如何在不使用API的情况下运行此示例。该示例使用作用域获取对API的读/写访问权。如果我从应用程序中删除对API的引用，它将不再工作。当然，应该有某种方法可以在不需要API的情况下对B2C进行身份验证？这对我的应用程序来说并不重要，但我最想知道的是，作为身份验证过程的一部分，Web服务是否必须存在 与Graph Api（Windows或Microsoft Graph？）通信。MS提供了ADAL和一些控
