c# - Alternative to use HttpContext in System.Web for Owin

Question

ASP.NET authentication is now based on OWIN middleware that can be used on any OWIN-based host. ASP.NET Identity does not have any dependency on System.Web.

I have an AuthorizeAttribute filter where I need to get the current user and add some properties to be retrieved later by action controllers.

The problem is that I have to use the HttpContext which belongs to System.Web. Is there any alternative of HttpContext for Owin?

public class WebApiAuthorizeAttribute : AuthorizeAttribute 
{
    public override async Task OnAuthorizationAsync(HttpActionContext actionContext, CancellationToken cancellationToken)
    {
        base.OnAuthorization(actionContext);

        Guid userId = new Guid(HttpContext.Current.User.Identity.GetUserId());

        ApplicationUserManager manager = new ApplicationUserManager(new ApplicationUserStore(new ApplicationDbContext())) { PasswordHasher = new CustomPasswordHasher() };
        ApplicationUser user = await manager.FindByIdAsync(userId);

        actionContext.Request.Properties.Add("userId", user.LegacyUserId);
    }
}

Note: I found this question, which seems a duplicate, but asks for a solution working for NancyFx project, which is not valid for me.

Answer 1

You can use OwinRequestScopeContext. Which is doing exactly what you are looking for.
