带有授权属性的帐户控制器中的UNITY MVC容器捕获空值

如何解决带有授权属性的帐户控制器中的UNITY MVC容器捕获空值

我有一个问题。我是UnityContainer的新手。我将Unity用于DI。

我的ASP.NET MVC Web应用程序具有一个AccountController属性的[Authorize]（由ASP.NET Identity自动生成）。

[Authorize]
public class AccountController : Controller
{
    private ApplicationSignInManager _signInManager;
    private ApplicationUserManager _userManager;

    [InjectionConstructor]
    public AccountController() { }

    public AccountController(ApplicationUserManager userManager,ApplicationSignInManager signInManager)
    {
        UserManager = userManager;
        SignInManager = signInManager;
    }

    public ApplicationSignInManager SignInManager
    {
        get
        {
            return _signInManager ?? HttpContext.GetOwinContext().Get<ApplicationSignInManager>();
        }
        private set
        {
            _signInManager = value;
        }
    }

    public ApplicationUserManager UserManager
    {
        get { return _userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>(); }
        private set { _userManager = value; }
    }

    [AllowAnonymous]
    public ActionResult Login(string returnUrl) { ViewBag.returnUrl = returnUrl; return View(); }

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginViewModel model) 
    {
       //My code
       return RedictToAction("Index","Home");
    }
   
    //Some Methods
    
}

查看我的完整代码：My simple AccountController was auto-generated by VS - Identity

我尝试为AccountController注入构造函数。

我的代码在App_Start > UnityConfig.cs中：

public static class UnityConfig
{
    public static IUnityContainer Container;

    public static void RegisterComponents()
    {
        var container = new UnityContainer();

        //register all my components with the container here            

        container.RegisterType<IUserStore<ApplicationUser>,UserStore<ApplicationUser>>();
        container.RegisterType<DbContext,ApplicationDbContext>(new PerRequestLifetimeManager());
        container.RegisterType<UserManager<ApplicationUser>>();
        container.RegisterType<ApplicationUserManager>();
        container.RegisterType<AccountController>(new InjectionConstructor());            
        
        DependencyResolver.SetResolver(new Unity.AspNet.Mvc.UnityDependencyResolver(container));
    }
}

My UnityConfig

当我开始运行应用程序并在AccountController上调用方法时，会显示以下错误消息：

值不能为null。参数名称：容器

请单击下面的链接查看错误消息：

The Exception was thrown. Url's localhost:xxxxx/Account/Login

我发现删除[Authorize]和[ValidateAntiForgeryToken]属性后，一切正常。

但是当我添加[Authorize]或[ValidateAntiForgeryToken]属性时，就会引发异常。

请帮助我修复它。

我真的很感激！

解决方法

我找到了答案。 在Application_Start

protected void Application_Start()
{
       AreaRegistration.RegisterAllAreas();
       FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
       RouteConfig.RegisterRoutes(RouteTable.Routes);
       BundleConfig.RegisterBundles(BundleTable.Bundles);
       UnityConfig.RegisterComponents(); //<--- Incorrect
}

我调整了

protected void Application_Start()
{
       AreaRegistration.RegisterAllAreas();
       UnityConfig.RegisterComponents(); //<========
       FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
       RouteConfig.RegisterRoutes(RouteTable.Routes);
       BundleConfig.RegisterBundles(BundleTable.Bundles);
}
