有条件禁用ASP.NET MVC控制器 [英] Conditionally disable ASP.NET MVC Controller

问题描述

什么是禁用ASP.NET MVC控制器的最佳方式有条件地？

我想有一个访问控制措施，如果在web.config中的一些值是真和404，如果是假

我应该写我自己的属性？

更新： 寻找更好的解决方案比动作过滤器属性（有能力通过不恒定的参数属性构造）

  [AttributeUsage（AttributeTargets.Class，的AllowMultiple = TRUE，继承=真）
    公共类CloseForSomeSettingAttribute：ActionFilterAttribute
    {
        公众覆盖无效OnActionExecuting（ActionExecutingContext filterContext）
        {
            布尔mySettingValue = MySettingManager.GetMySettingValue（）;

            如果（mySettingValue）
            {
                filterContext.Result =新的HTTPStatus codeResult（404）;
            }
            其他
            {
                base.OnActionExecuting（filterContext）;
            }
        }
    }
 

解决方案

最简单的将可能实现自定义的行为过滤器：

您也可以有条件地添加相匹配的控制器，将导致404返回路线。

What is the best way to disable ASP.NET MVC controller conditionally?

I want to have an access to the controller actions if some value in web.config is "true" and 404 if it's "false"

Should I write my own attribute?

UPDATE: Looking for more elegant solution than action filter attribute (with an ability to pass not constant parameter to attribute constructor)

    [AttributeUsage(AttributeTargets.Class, AllowMultiple = true, Inherited = true)]
    public class CloseForSomeSettingAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            bool mySettingValue = MySettingManager.GetMySettingValue();

            if (mySettingValue)
            {
                filterContext.Result = new HttpStatusCodeResult(404);
            }
            else
            {
                base.OnActionExecuting(filterContext);
            }
        }
    }

解决方案

The easiest would probably be to implement a custom action filter:

You can also conditionally add a route that matches that controller that would result in a 404 being returned.
