How to create custom Authorization in ASP.NET Core (ASP.NET 5)

Question

I would like to have custom implementation of [Authorize] attribute in controlles.

This is what I did.

1. StartupClass in ConfigureServices

   services.AddAuthorization(options =>
   {    
       options.AddPolicy("Authorize", policy =>
       {   
            policy.AddRequirements(new MyRequirement());
       });
   });
   

2. MyRequirement

   public class MyRequirement : AuthorizationHandler<MyRequirement>, IAuthorizationRequirement
   {
       protected override void Handle(AuthorizationContext context, MyRequirement requirement)
       {
           //some work
           //if shloud be authorized
           context.Succeed(requirement);
       }
   }
   

3. TestController

   [Authorize("Authorize")]
   [Route("api/[controller]")]
   public class TestController : Controller
   {
     ...
   }
   

What I'm I missing? MyRequirement authorizationhader is never called. Thank you.

I believe you are missing this part:

services.AddSingleton<IAuthorizationHandler, MyRequirementHandler>();
