使用 lightinject 拦截在 mvc 5 中使用参数拦截动作控制器

Question

我无法拦截带参数的控制器操作。我正在使用 Asp.Net MVC 5 与 LightInject 和 LightInject.Interception。我收到以下错误：

Unable to cast object of type 'System.Object[]' to type 'System.Web.Mvc.CustomModelBinderAttribute[]'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Unable to cast object of type 'System.Object[]' to type 'System.Web.Mvc.CustomModelBinderAttribute[]'.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

我的代码是（我没有插入视图，因为它们没有意义）：

// Global.asax
namespace TestMVCInjection
{
    using System;
    using System.Diagnostics;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    using System.Web.Routing;
    using LightInject;
    using LightInject.Interception;

    using TestMVCInjection.Controllers;

    public class MvcApplication : HttpApplication
    {
        public void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            //FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            GlobalFilters.Filters.Add(new HandleErrorAttribute());
            //RouteConfig.RegisterRoutes(RouteTable.Routes);
            RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            RouteTable.Routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

            RegisterLightInject();
        }

        private void RegisterLightInject()
        {
            var container = new ServiceContainer();
            container.RegisterControllers();
            container.EnableMvc();
            container.Intercept((ServiceRegistration c) => c.ServiceType == typeof(HomeController), (IServiceFactory c) => (IInterceptor)new DebugInterceptor());
        }
    }

    public class DebugInterceptor : IInterceptor
    {
        public object Invoke(IInvocationInfo invocationInfo)
        {
            object returnValue = null;
            // Verifico se devo intercettare il metodo
            var mi = invocationInfo.Method;
            var sw = Stopwatch.StartNew();
            string timestamp = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ss.fff \"GMT\"zzz");
            string method = $"{invocationInfo.Method.DeclaringType.Name}.{invocationInfo.Method.Name}";
            try
            {
                var parNames = invocationInfo.Method.GetParameters().Select(d => $"{d.Name}: {d.ParameterType}").ToList();
                var parValues = invocationInfo.Arguments.Select(c => $"{c}").ToList();
                string parameters = string.Join(Environment.NewLine, parNames.Select((n, i) => $"{parNames[i]} = {parValues[i]}"));
                string message = $"{nameof(timestamp).ToUpper()}={timestamp}{Environment.NewLine}{nameof(method).ToUpper()}={method}{Environment.NewLine}{nameof(parameters).ToUpper()}{Environment.NewLine}{parameters}";
                Debug.WriteLine(message);
                returnValue = invocationInfo.Proceed();
                message = $"TOOK {nameof(sw.ElapsedMilliseconds)} = {sw.ElapsedMilliseconds} for returning {returnValue} for method {method}";
                Debug.WriteLine(message);
                return returnValue;
            }
            catch (Exception)
            {
                string message = $"Took {nameof(sw.ElapsedMilliseconds)} = {sw.ElapsedMilliseconds} for throwing an exception method {method}";
                Debug.WriteLine(message);
                throw;
            }
        }
    }
}

我的控制器是：

namespace TestMVCInjection.Controllers
{
    using System.Diagnostics;
    using System.Web.Mvc;

    public class HomeController : Controller
    {
        public virtual ActionResult Index(string id)
        {
            Debug.WriteLine("-----> INDEX START <-----");
            var response = View((object)id);
            Debug.WriteLine("-----> INDEX END <-----");
            return response;
        }
    }
}

希望有人能指导我正确的方法。

在 github 存储库上发布了一个问题。几个小时前已更正 (LightInject.Inteception 2.0.1)。
