How to get the incoming access token in ASP.NET API

Question

I need to run some logic in an ASP.NET API action using the claims in the passed in access token. How do I get the access token? And later how do I get the claim value in the access token?

[HttpGet]
[Authorize(Policy = "PaidMember")]
[Route("GetVideos")]
public async Task<IEnumerable<VideoModel>> GetVideos(string topicId)
{
    var accessToken = ... // TODO: Get the access token here

    // Then something like the following
    var type = accessToken.GetValue("membershiptype") // This line is made up
    return await _service.GetVideos(topicId, type );
}

You can get the claims with :

HttpContext.User.Claims

See here for get a specific claim : Extract values from HttpContext.User.Claims

I suggest you to use the ASP pipeline with Authorization middlware if you want to check claims. See Microsoft Docs - ASP.NET Core Middleware.

You can get the claim value like this:

(User.Identity as ClaimsIdentity).FindFirst("membershiptype").Value

With this you do not need to get the original token
