我正在尝试在类中使用UserManager,但我收到此错误:
Error activating IUserStore{ApplicationUser} No matching bindings are available,and the type is not self-bindable.
我正在使用默认的Startup.cs,它为每个请求设置一个实例:
app.CreatePerOwinContext(ApplicationDbContext.Create); app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
我能够得到ApplicationDbContext实例,我相信它是由Owin注入的(这是真的吗?):
public class GenericRepository<T> : IGenericRepository<T> where T : class { private ApplicationDbContext context; public GenericRepository(ApplicationDbContext context) { this.context = context; } }
但我不能用UserManager做同样的事情(它抛出之前显示的错误):
public class AnunciosService : IAnunciosService { private IGenericRepository<Anuncio> _repo; private ApplicationUserManager _userManager; public AnunciosService(IRepositorioGenerico<Anuncio> repo,ApplicationUserManager userManager) { _repo = repo; _userManager = userManager; } }
控制器像这样使用UserManager:
public ApplicationUserManager UserManager { get { return _userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>(); } private set { _userManager = value; } }
我正在使用ninject注入我的其他类,但是如何使用它的依赖项注入UserManager并避免在我的控制器中使用它?
解决方法
我像这样注射它
kernel.Bind<IUserStore<ApplicationUser>>().To<UserStore<ApplicationUser>>(); kernel.Bind<UserManager<ApplicationUser>>().ToSelf();
而现在它正在发挥作用.
