Providing a custom endpoint for OAuthBearerAuthenticationOptions

Jul 2, 2014 at 9:39 PM
Hi Folks,

I am trying to get an access token from an OAuth2 server and hoping to use UseOAuthBearerAuthentication extension method on IAppBuilder. What is the best way to provide a custom endpoint for retrieving the token?

I think you're looking for OAuthBearerAuthenticationOptions.AccessTokenProvider, which may be a AuthenticationTokenProvider (See AuthenticationTokenProvider.OnReceiveAsync).

Hi Tratcher,

Can you elaborate a bit more? ReceiveAsync takes AuthenticationTokenReceiveContext, which takes IOwinContext and has Token and AuthenticationTicket with AuthenticationProperties. AuthenticationProperties only allow RedirectUri to be set. I couldn't find any relevant properties or methods in IOwinContext either.

My intent is to have my client get an access token from an OAuth server, but haven't yet found anywhere I can provide either the URL or parameters to construct the URL.

You implement OnReceiveAsync to make the HTTP request yourself for the access token, and then return the result. There's nowhere you can supply a URL and ask someone else to make the request for you.
