Question

目前我正在尝试设置依赖注入并覆盖授权属性。我试图遵循一些例子，虽然我似乎总是出错。

Global.asax中

public class MvcApplication : Ninject.Web.Mvc.NinjectHttpApplication
{
    private class MyModule : NinjectModule
    {
        public override void Load()
        {
            this.BindFilter<SageAdminAuthorizationFilter>(FilterScope.Controller, 0);
            Bind<IAuthentication>().To<CustomAuthenticationService>();
        }
    }

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default",
            "{controller}/{action}/{id}",
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }

    protected override void OnApplicationStarted()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }

    protected override IKernel CreateKernel()
    {
        var modules = new INinjectModule[] {
        new MyModule()
    };
        var kernel = new StandardKernel(modules);

        return kernel;
    }
}

身份验证过滤器

public class CustomAuthenticationService : IAuthentication
{
    public void SignIn(string claimedIdentifier, bool createPersistentCookie)
    {
        //Write Sign in code here
        FormsAuthentication.SetAuthCookie(claimedIdentifier, createPersistentCookie);
    }

    public void SignOut()
    {
        FormsAuthentication.SignOut();
    }

    public bool Authorize(HttpContextBase httpContext)
    {
        //Check here if the user can administer the  admin
        return false;
    }
}

//The Authorization attribute on a controller
public class CustomAdminAuthorizationFilter : IAuthorizationFilter
{
    private readonly IAuthentication _authentication;

    public SageAdminAuthorizationFilter(IAuthentication authentication)
    {
        _authentication = authentication;
    }

    public void OnAuthorization(AuthorizationContext filterContext)
    {
        _authentication.Authorize(filterContext.HttpContext);
    }
}

我总是收到

任何帮助都会受到赞赏。

更新：我仍然收到同样的错误。

调用堆栈如下

我已经从Nuget安装了Ninject和Ninject.MVC3。它看起来虽然它试图找到要调试的文件。是否有人能够向我提供有关为何发生这种情况的任何信息。

我也收到此错误

Answer 1

应使用以下语法注册操作过滤器：

public override void Load()
{
    BindFilter<CustomAdminAuthorizationFilter>(FilterScope.Controller, 0);
    Bind<IAuthentication>().To<CustomAuthenticationService>();
}

您也可以apply the filter conditionally。

备注：无法看到您在问题中显示的NinjectDependencyResolver课程的任何关系。这已经内置到ninject.mvc3中，你不应该手动编写它。
