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?

You can try
你可以试试
public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
{
string username = HttpContext.Current.User.Identity.Name;
}
Check for authenticated user first:
首先检查认证用户：
string userName = null;
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
userName = HttpContext.Current.User.Identity.Name;
}
Try to use
尝试使用
HttpContext.Current.User.Identity.Name
Hope it works for you
希望这对你有用

Perhaps not the prettiest solution, but for Web API ActionFilter you can do the following:
也许不是最漂亮的解决方案，但对于 Web API ActionFilter，您可以执行以下操作：
var controller = (actionContext.ControllerContext.Controller as ApiController);
var principal = controller.User;
Of course, this only applies if your controllers actually inherit from ApiController.
当然，这仅适用于您的控制器实际上是从 ApiController 继承的。

Bit late for an answer but this is best solution if you are using HttpActionContext in your filter You can always use it as mentioned here:-
答案有点晚，但如果您在过滤器中使用 HttpActionContext，这是最好的解决方案您可以随时使用它，如下所述：-
public override Task OnActionExecutingAsync(HttpActionContext actionContext, CancellationToken cancellationToken)
{
if (actionContext.RequestContext.Principal.Identity.IsAuthenticated)
{
var userName = actionContext.RequestContext.Principal.Identity.Name;
}
}
