ASP.NET Web API Basic Authentication Authorisation Header

I noticed myself that if the Authorization-header only contained the key/token, the request.Headers.Authorization wouldn't be initiated properly because it's looking for a scheme as well in the format <Scheme> <key/token>, i.e. Authorization: Token VXNlcjpQYXNzd29yZA==, then the Authorization wouldn't be null anymore and contain request.Headers.Authorization.Scheme = "Token" and request.Headers.Authorization.Parameter = "VXNlcjpQYXNzd29yZA=="

I've posted my own example of a Basic Authentication Attribute. Maybe this gives you some hints.

I use:

HttpContext.Current.Request.Headers["Authorization"];

And here is the link to the complete solution:

If you get stuck on this, you can get the header using:

var header = request.Headers.FirstOrDefault(h => h.Key.Equals("Authorization"));

But not via

var header = request.Headers.Authorization;

Though, this thread is very old but it might help others if I share how did I resolve it in my case:

Request should contain

Authorization: Basic VXNlcjpQYXNzd29yZA==

instead of:

Authorization: VXNlcjpQYXNzd29yZA==

so following change in request may solve the problem:

client.Headers.Add("Authorization", "Basic VXNlcjpQYXNzd29yZA==");
