继承Controller,ApiController的拦截继承的接口不一样

webapi的拦截器：（继承System.Web.Http）

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Http.Controllers;using System.Web.Http.Filters;using System.Configuration;namespace Rongzi.Mi.Mvc{     public class IosApproveFilterAttribute : System.Web.Http.Filters.ActionFilterAttribute    {        private readonly bool IosApprove = Convert.ToBoolean(ConfigurationManager.AppSettings["IOSApprove"] == null ? "0" : ConfigurationManager.AppSettings["IOSApprove"]);        public override void OnActionExecuting(HttpActionContext actionContext)        {            base.OnActionExecuting(actionContext);        }        public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)        {            if (IosApprove)            {                actionExecutedContext.ActionContext.Response.Headers.Add("IOSApprove", "true");            }            base.OnActionExecuted(actionExecutedContext);        }    }}

Controller的拦截：（继承System.Web.Mvc）

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Http.Controllers;using System.Configuration;using System.Web.Mvc;namespace Rongzi.Mi.Mvc{    public class IosApproveFilterAttribute : System.Web.Mvc.ActionFilterAttribute    {        private readonly bool IosApprove = ConfigurationManager.AppSettings["IOSApprove"] == "1" ? true : false;        public override void OnActionExecuting(ActionExecutingContext actionContext)        {            base.OnActionExecuting(actionContext);                    }        public override void OnActionExecuted(ActionExecutedContext actionExecutedContext)        {            if (IosApprove)            {                actionExecutedContext.HttpContext.Response.Headers.Add("IOSApprove", "true");            }            base.OnActionExecuted(actionExecutedContext);        }    }}

可以发现他们的继承抽象类都不一样，虽然名称一样，但是是不同的命名空间。
