How to redirect to an ASP.net MVC action for url with hash parameter

问题

I am using ASP.Net core 2.2. I redirect to an identity server instance, which then redirects back to my MVC app. The redirect back url is of the form:

http://localhost:8081/home/fetchtokenresponse#id_token=longtokenvalue&token_type=Bearer&expires_in=3600&scope=myscopes&session_state=jizlw_6DiGhYvkGk6fKRKkhZQoFlYKJ5v1_2Lwd-caI.MN0g0HwpGuulkwKleHtJCg

In my action I want to be able to read the parameters like

public IActionResult FetchTokenResponse(string id_token)

What I have tried

I tried adding a new route with a has tag, but this appears to be illegal:

routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}#{id?}");

Is there another way to intercept the path and redirect to my action?

You will need to modify your authentication request to IdentityServer to use response_mode=form_post or response_mode=query.

Fragments are not sent to the server, as defined in: https://blog.httpwatch.com/2011/03/01/6-things-you-should-know-about-fragment-urls/. Fragment response mode is used when you want your front-end JavaScript to grab the tokens.
