Build in AuthenticationStateProviders from project templates #55821

halter73 · 2024-05-21T16:01:45Z

This automatically registers a client AuthenticationStateProvider's similar to the PersistentAuthenticationStateProvider added by the "Individual Auth" option in the Blazor Web project templates.

This feature must be opted in by calling AddAuthenticationStateSerialization() on the server's IRazorComponentsBuilder and AddAuthenticationStateDeserialization() on the client's IServiceCollection. These methods are defined in Microsoft.AspNetCore.Components.WebAssembly.Server and Microsoft.AspNetCore.Components.WebAssembly.Authentication assemblies respectively, so they should only be available to applications using WebAssembly interactivity.

Even if you do opt-in to authentication state serialization/deserialization, you must further opt-in to serializing all claims by setting AuthenticationStateSerializationOptions.SerializeAllClaims or registering a custom SerializationCallback. Otherwise, only the name and role claims will be serialized.

Rather than override the server's AuthenticationStateProvider like the project template's PersistingServerAuthenticationStateProvider, this registers an AuthenticationStateSerializer which does not implement AuthenticationStateProvider. This allows EndpointHtmlRenderer to flow authentication state from a custom server-side AuthenticationStateProvider to the serializer which is registered directly as IHostEnvironmentAuthenticationStateProvider by AddAuthenticationStateSerialization().

In order to increase the consistency of using AddAuthenticationStateSerialization() with and without server interactivity, ServerAuthenticationStateProvider was type forwarded to Microsoft.AspNetCore.Components.Endpoints and registered by default by AddRazorComponents. This is also helpful for auth in completely non-interactive Blazor web projects.

Fixes #52769

- Use JSImports instead of DefaultWebAssemblyJSRuntime - Remove unnecessary exclusions from template.json - Remove UserInfo from the template client template - Remove AddAuthorizationCore from AddRazorComponents

Is this public because of layering?

Or because we want it to be extendable

I mention this in the PR description:

This is also helpful for auth in completely non-interactive Blazor web projects.

This change isn't strictly necessary for this PR, but I do think it helps with the general usability AddRazorComponents without AddInteractiveServerComponents. I could have used an internal AuthenticationStateProvider that's functionally equivalent to the ServerAuthenticationStateProvider without the type forwarding to achieve the same thing, but I figured we might as well reduce duplication.

Isn't this breaking? (For libraries for example).

The [assembly: TypeForwardedTo(typeof(Microsoft.AspNetCore.Components.Server.ServerAuthenticationStateProvider))] should make it non-breaking.

I have some more comments, but I don't want to block on them. I'll chat with you offline

Feel free to reject this but the sentence is too long and difficult to machine translate.

@tdykstra why no rich diff?

I don't know, but your new line 21 is missing one slash at the start.
