Question

我有使用客户操作过滤器属性的操作方法＆＃34; FeatureAuthenticationAttribute＆＃34;，我想将标志值传递给过滤器;

如果传递标志值为false，则应重定向到FeatureDenied Action Method。为此：

[FeatureAuthenticationAttribute(flagvalue)]
public ActionResult Jobs()
{
    return View();
}

public ActionResult FeatureDenied()
{
    return View();
}

对于过滤器：

[AttributeUsage(AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
public class FeatureAuthenticationAttribute : FilterAttribute, IAuthorizationFilter
{
    public override void OnAuthorization (AuthorizationContext filterContext,bool flagvalue)
    {
        if (flagvalue== false) // I want to check here
        {
            string redirectURL = @"~/Employer/FeatureDenied";// Redirect to Action Method 

            filterContext.Result = new RedirectResult(redirectURL);
        }
    }
}

有可能像上面那样吗？如果是这样，我正在使用Filter属性来实现或执行此操作。请帮帮我。

你可以在Controller中制作这样的routedata：

RouteData.Values.Add("flag", true/false);

过滤：

 [AttributeUsage(AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
 public class FeatureAuthenticationAttribute : FilterAttribute, IAuthorizationFilter
 {
  public override void OnAuthorization (AuthorizationContext filterContext,bool flagvalue)
   {
        if (filterContext.RouteData.Values["flag"]== false) // I want to check here
        {

            string redirectURL = @"~/Employer/FeatureDenied";// Redirect to Action Method 

            filterContext.Result = new RedirectResult(redirectURL);

        }

    }
 }
