拦截动作控制器，带有 mvc 5 中的参数，具有注入拦截功能

Question

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

无法将类型为"System.Object[]"的对象转换为类型"System.Web.Mvc.CustomModelBinderAttribute[]"。 说明：执行当前 Web 请求期间发生未经处理的异常。请查看堆栈跟踪，了解有关错误及其在代码中起源位置的详细信息。

异常详细信息：System.InvalidCastException：无法将类型为"System.Object[]"的对象转换为类型"System.Web.Mvc.CustomModelBinderAttribute[]"。

源错误：

在执行当前 Web 请求期间生成了未经处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常来源和位置的信息。

我的代码是(我不插入视图，因为毫无意义(：

// 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;
}
}
}

希望有人能引导我走正确的路。
