Mediarq.Authorization

ASP.NET Core policy-based authorization as a pipeline behavior: mark a command/query as IAuthorizedRequest, and it is checked before its handler runs — no authenticated user short-circuits with a 401, a failed policy short-circuits with a 403, both as a typed Result failure your handler never has to think about.

dotnet add package Mediarq.Authorization

Usage

builder.Services.AddAuthorization(); // ASP.NET Core's own registration
builder.Services.AddHttpContextAccessor();
builder.Services.AddMediarqAuthorization();

public record DeleteOrder(Guid OrderId) : ICommand, IAuthorizedRequest
{
    public string? PolicyName => "OrdersAdmin";
}
  • PolicyName set → evaluated via IAuthorizationService.AuthorizeAsync(user, request, policyName), so a custom IAuthorizationHandler can inspect the request itself (e.g. checking OrderId ownership), not just the policy name.
  • PolicyName set to null → only requires an authenticated user, no specific policy.
  • Not authenticated → Result.Failure(ResultError.Unauthorized(...)) (maps to HTTP 401 via Mediarq.AspNetCore).
  • Authenticated but the policy fails → Result.Failure(ResultError.Forbidden(...)) (HTTP 403).
  • Requests that don't implement IAuthorizedRequest pass straight through — this behavior costs nothing for them (IConditionalPipelineBehavior.IsActive is false for their closed type, so the pipeline never even resolves it into the chain).

Response type

The handler's response type must be Result or Result<T> — the behavior needs some way to represent an authorization failure as a value. Result is handled without reflection; Result<T> uses a one-time-per-T reflection fallback (cached afterwards), so it is not on the Native AOT-safe path — the same trade-off the core ValidationBehavior makes for its own Result<T> fallback.
