Blazor - Check User Authorization for a Blazor Page based on URL

[JaKuBisz]

What I aim to achieve:

I want to check if the current user has access rights to a specific page (Blazor component) in my Blazor application based on the page URL (or Type of Page for that matter).

Ideally, I'd like to do something like this:

var state = await AuthenticationStateProvider.GetAuthenticationStateAsync();
var hasAccess = (await AuthorizationService.AuthorizeAsync(state.User, "/myPage")).Succeeded;

Is there an existing framework feature or a recommended pattern to handle this scenario or should I implement my custom logic for matching URLs to Page types and then extract the page policy using reflection from the attributes?

My Blazor Page (Component) example:

@page "/myPage"
@attribute [Authorize(Policies.MyPolicy)]

Could you please advise if there's an existing method to achieve this within ASP.NET Core, or I will need to develop a custom solution?
