microsoft-graph-api - 如何将 SimpleProvider 与我自己的 MSAL C# 代码一起使用

Question

我正在尝试使用我自己的 MSAL 代码一起工作。使用 .NET Core 5 MVC 开发。我在下面的链接中发现了类似的问题。但我只是不知道如何使它与建议的答案一起工作。或者换句话说，我仍然对这种集成是如何完成的感到困惑。

我也读过以下文章：[简单提供程序示例] https://github.com/microsoftgraph/microsoft-graph-toolkit/blob/main/samples/examples/simple-provider.html

是否有人可以向我指出有关如何存档的更多详细信息。

有人可以在下面的回复中进一步解释。怎么做。我应该在哪里放置代码以及如何将 AccessToken 返回给 SimpleProvider？

编辑：

除了问题之外，更新我的问题以更准确地表达我想要的内容。下面是我在 Startup.cs 中使用的代码，用于在用户使用 Web 应用程序时自动触发弹出屏幕。使用提供的示例时，始终无法获取接收到的访问令牌或用户 ID 数据。问题 2：如何将收到的令牌保存或存储在内存或缓存或 cookie 中以供 ProxyController 及其类以后使用。

Answer 1

Finally, I have discovered how to do my last mile bridging for these two technology.

Following are the lines of the code that I have made the changes. Since I'm using new development method as oppose by MSAL.NET, a lot of implementation has been simplified, so many of examples or article out there, may not really able to use it directly.

Besides using links shared by @Nikola and me above, you also can try to use below https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/master/ to consolidate to become your very own solution. Below are the changes I have made to make it worked.

Change in Startup.cs class

// Add application services. services.AddSingleton<IGraphAuthProvider, GraphAuthProvider>(); //services.AddSingleton<IGraphServiceClientFactory, GraphServiceClientFactory>();

Change in ProxyController.cs class

private readonly GraphServiceClient _graphClient; 

public ProxyController(IWebHostEnvironment hostingEnvironment, GraphServiceClient graphclient)
    {
        _env = hostingEnvironment;
        //_graphServiceClientFactory = graphServiceClientFactory;
        _graphClient = graphclient;
    }

Change in ProcessRequestAsync method under ProxyController.cs

 //var graphClient = _graphServiceClientFactory.GetAuthenticatedGraphClient((ClaimsIdentity)User.Identity);
       
        var qs = HttpContext.Request.QueryString;
        var url = $"{GetBaseUrlWithoutVersion(_graphClient)}/{all}{qs.ToUriComponent()}";

        var request = new BaseRequest(url, _graphClient, null)
        {
            Method = method,
            ContentType = HttpContext.Request.ContentType,
        };
