Get User Name on Action Filter

Question

I use MVC4 web application with Web API. I want to create an action filter, and I want to know which user (a logged-in user) made the action. How can I do it?

public class ModelActionLog : ActionFilterAttribute
{
    public override void OnActionExecuting(SHttpActionContext actionContext)
    {
       string username = ??
    }

    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
       ??
    }
}

You can try

public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
        {
           string username = HttpContext.Current.User.Identity.Name;
        }

Check for authenticated user first:

string userName = null;
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
    userName = HttpContext.Current.User.Identity.Name;
}

Try to use

HttpContext.Current.User.Identity.Name

Hope it works for you
