ASP.NET MVC3 IAuthorisationfilter Ninject依赖项

Question

目前，我正在尝试设置依赖项注入，并覆盖授权属性。我试着效仿一些例子，尽管我似乎总是会犯错误。

Global.asax

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;
    }
}

认证过滤器

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

序列不包含任何元素。

任何帮助都将不胜感激。

更新:我仍然收到相同的错误。

调用堆栈如下所示

我已经安装了Ninject和Ninject.MVC3从Nuget。虽然它正在试图查找要调试的文件，但它看起来是这样的。有没有人能告诉我为什么会发生这种事。

我也收到了这个错误。

Answer 1

应使用以下语法注册操作筛选器：

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

你也可以apply the filter conditionally。

备注:在您的问题中看不到与NinjectDependencyResolver类的任何关系。这已经内置在ninject.mvc3中了，您不应该手动编写它。

通过取消选中“要求源文件与原始版本完全匹配”旁边的复选框解决问题。
