The IIdentityServerInteractionService interface is intended to provide services to be used by the user interface to communicate with IdentityServer, mainly pertaining to user interaction. It is available from the dependency injection system and would normally be injected as a constructor parameter into your MVC controllers for the user interface of IdentityServer.

GetAuthorizationContextAsync

Returns the AuthorizationRequest based on the returnUrl passed to the login or consent pages.

IsValidReturnUrl

Indicates if the returnUrl is a valid URL for redirect after login or consent.

GetErrorContextAsync

Returns the ErrorMessage based on the errorId passed to the error page.

GetLogoutContextAsync

Returns the LogoutRequest based on the logoutId passed to the logout page.

CreateLogoutContextAsync

Used to create a logoutId if there is not one presently. This creates a cookie capturing all the current state needed for signout and the logoutId identifies that cookie. This is typically used when there is no current logoutId and the logout page must capture the current user's state needed for sign-out prior to redirecting to an external identity provider for signout. The newly created logoutId would need to be round-tripped to the external identity provider at signout time, and then used on the signout callback page in the same way it would be on the normal logout page.
