How to acquire a token with Azure AD and MSAL in ASP.NET

问题

I'm trying to authenticate a token using Azure AD. In a console application, I have no problem with this thanks to IConfidentialClientApplication:

static void Main(string[] args)
{
    Console.WriteLine("Making the call...");
    RunAsync().GetAwaiter().GetResult();
}

private static async Task RunAsync()
{
    AuthConfig config = AuthConfig.ReadJsonFromFile("appsettings.json");

    IConfidentialClientApplication app;

    app = ConfidentialClientApplicationBuilder.Create(config.ClientId)
        .WithClientSecret(config.ClientSecret)
        .WithAuthority(new Uri(config.Authority))
        .Build();

    string[] ResourceIds = new string[] { config.ResourceId };

    AuthenticationResult result = null;

    try
    {
        result = await app.AcquireTokenForClient(ResourceIds).ExecuteAsync();
    }
    ...
}

But in a Startup for an ASP.NET Core application, the app uses the standard IApplicationBuilder and the Configure(...) method can't take an IConfidentialClientApplicationBuilder as it doesn't exist.

In Microsoft's documentation, they create a PublicClientApplicationBuilder, but I don't want to start creating entirely new applications in my configuration.

Here is a sample of Startup for ASP.NET Core application for your reference. But as far as I know we can't get token directly in the Startup for ASP.NET Core application with "IApplicationBuilder". "IApplicationBuilder" and "IConfidentialClientApplicationBuilder" are two different concepts.

For your requirement, you can just import modules for msal and use the code you provided above or the code you mentioned in the Microsoft's documentation to get the token.
