中止/取消从ActionFilter行动最好的办法

Best way to abort/cancel action from ActionFilter

我这有 ActionFilter ，它的假设立即断开连接并返回401 Unauthroized：

I've got this ActionFilter, and it's suppose to end the connection immediately and return a 401 Unauthroized:

public class SignInRequired : ActionFilterAttribute 
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // User is verified, continue executing action

        if (Acme.Web.CurrentUser != null)
        {
            return;
        }

        // End response with 401 Unauthorized

        var response = HttpContext.Current.Response;
        response.StatusCode = (int)HttpStatusCode.Unauthorized;
        response.End();

        // Prevent the action from actually being executed

        filterContext.Result = new EmptyResult();
    }
}

我学会了如何你可以通过设置'context.Result =新EmptyResult（）`的这里，但我不知道这是冲洗反应和关闭连接的最佳方式。

I learned how you can cancel the action from executing by setting 'context.Result = new EmptyResult()` here, but I'm not sure if this is the best way to flush the response and close the connection.

推荐答案

设置响应将意味着动作不会被调用。

Setting the response will mean the action doesn't get called.

public override void OnActionExecuting(HttpActionContext actionContext)    
{ 
    actionContext.Response = new HttpResponseMessage(HttpStatusCode.Unauthorized);
}

至于其他的答案说，虽然，验证应与AuthorizeAttribute（文档的为Web.API 或的为MVC ）。
