AuthenticationManager HttpContext is Null

本文关键字：Null is HttpContext AuthenticationManager | 更新日期: 2023-09-27 18:11:21

我想在我的控制器中使用这段代码:

IAccountManagementService<User> _service;
public AccountController(IAccountManagementService<User> service)
{
    _service = service;
    _service.AuthenticationManager = HttpContext.GetOwinContext().Authentication;
    _service.UserManager = new UserManager<User>(new UserStore<User>(new DefaultContext()));
}

并且它稍微适应了ASP模板的原始样板代码。. NET MVC 5

它是通过Ninject注入的，Ninject使用依赖解析器和模块加载器:

var kernel = new StandardKernel(new ModuleLoader());
DependencyResolver.SetResolver(new NinjectDependencyResolver(kernel));

所以我不知道这是不是把上下文搞乱了

服务只是将原始代码抽象到其中，服务看起来像这样:

IRepository _repository;
public AccountManagementService(IRepository repository)
{
    _repository = repository;
}
public UserManager<User> UserManager { get; set; }
public IAuthenticationManager AuthenticationManager { get; set; }
public RoleManager<IdentityRole> RoleManager { get; set; }

原始代码看起来像这样:

public AccountController()
            : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext())))
{
}
public AccountController(UserManager<ApplicationUser> userManager)
{
    UserManager = userManager;
}
public UserManager<ApplicationUser> UserManager { get; private set; }
private IAuthenticationManager AuthenticationManager
{
    get
    {
        return HttpContext.GetOwinContext().Authentication;
    }
}

我可能会注射IAuthenticationManager，但还没有真正研究过。

我只是不确定当我加载我的网站，我点击登录，它带我到控制器的构造函数，并指向行开始:_service.AuthenticationManager，并告诉我，HttpContext是空的。

AuthenticationManager HttpContext is Null

我通过重新做所有的Ninject依赖注入来修复这个问题。我现在遵循Ninject的约定MVC 5

我为ASP添加了这些绑定。NET身份:

//<----- ACCOUNT STUFF ----->''
kernel.Bind<IUserStore<EbpUser>>().To<UserStore<EbpUser>>().WithConstructorArgument("context", context => kernel.Get<DefaultContext>());
kernel.Bind<IRoleStore<IdentityRole, string>>().To<RoleStore<IdentityRole, string, IdentityUserRole>>().WithConstructorArgument("context", context => kernel.Get<DefaultContext>());

为了得到HttpContext，我绑定了AuthenticationManager:

kernel.Bind<IAuthenticationManager>().ToMethod(c => HttpContext.Current.GetOwinContext().Authentication).InRequestScope();

在我的AccountManagementService中，我现在这样做:

IRepository _repository;
IAuthenticationManager _authManager;
UserManager<EbpUser> _userManager;
RoleManager<IdentityRole> _roleManager;
public AccountManagementService(IRepository repository, IUserStore<EbpUser> userStore, IRoleStore<IdentityRole, string> roleStore, IAuthenticationManager authManager)
{
    _repository = repository;
    _authManager = authManager;
    _userManager = new UserManager<EbpUser>(userStore);
    _roleManager = new RoleManager<IdentityRole>(roleStore);
}

所以现在一切都注入正确，它看起来整洁多了
