　　需要调用的 Controller类上加上验证类名

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebApplication1.App_Start;

namespace WebApplication1.Controllers
{
    [ControllerValidate]
    public class Test1Controller : Controller
    {
        //
        // GET: /Test1/
        public ActionResult Index()
        {
            return View();
        }
    }
}

using WebApplication1.App_Start;
using System.Net;
using System.Net.Http;
using System.Web.Http;

namespace MvcApplication1.Controllers
{
    [ApiControllerValidate]
    public class TestController : ApiController
    {
        [HttpGet]
        public dynamic Index()
        {
            return Request.CreateResponse(HttpStatusCode.OK, new
            {
                Success = true,
                Message = ""
            });
        }
    }
}
