[英]Azure Active Directory won't logout using ASP.NET Core 2.1 MVC
[英]Authenticate ASP.NET Core 2.1 Web API with Azure Active Directory and Azure SQL with Entity Framework
我已經在Azure SQL數據庫上實現了Azure AD身份驗證,並想為其編寫使用相同AD身份驗證的Web API,但是我需要將該身份驗證從Web API傳遞到Azure SQL連接。 我們還希望在該項目中使用實體框架。
Web API的Startup類中的UseSqlServer
函數通過帶有身份驗證詳細信息的連接字符串傳遞,因此我想解決此問題的方法是基於Web API身份驗證的用戶以某種方式使連接動態化。
這是我們正在查看的圖形化地圖:
| azure active directory |
|| ||
\/ \/
client ------> | web api | ------> | azure sql |
最好的方法是什么?
您是否考慮過使用令牌進行身份驗證? 您將在此處找到示例應用程序。
