HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>() 得到这个 InvalidOperationException

Question

我使用 ASP.NET Identity 2 来创建注册用户逻辑，但在 HttpContext.GetOwinContext().GetUserManager().

处出现异常

可能是什么问题？感谢您的任何建议。

有注册控制器

public class AccountController : Controller
{
    private ApplicationUserManager UserManager
    {
        get
        {
            return HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
        }
    }

    public ActionResult Register()
    {
        return View();
    }

    [HttpPost]
    public async Task<ActionResult> Register(RegisterUserModel model)
    {
        if (ModelState.IsValid)
        {
            AppUser user = new AppUser { UserName = model.Email, Email = model.Email };
            IdentityResult result = await UserManager.CreateAsync(user);
            if (result.Succeeded)
            {
                return RedirectToAction("Login", "Account");
            }
            else
            {
                foreach (string error in result.Errors)
                {
                    ModelState.AddModelError("", error);
                }
            }
        }
        return View(model);
    }
}

ApplicationUserManager 逻辑

public class ApplicationUserManager : UserManager<AppUser>
{
    public ApplicationUserManager(IUserStore<AppUser> store) 
        : base(store) 
{
    }
    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options,
                                            IOwinContext context)
    {
        IdentificationContext db = context.Get<IdentificationContext>();
        ApplicationUserManager manager = new ApplicationUserManager(new UserStore<AppUser>(db));
        return manager;
    }
}

注册机型

public class RegisterUserModel
{
    [Required]
    [StringLength(255)]
    [RegularExpression(@"[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}")]
    public string Email { get; set; }
    [Required]
    [DataType(DataType.Password)]
    [StringLength(255, MinimumLength = 5)]
    public string Password { get; set; }
    [Required]
    [System.ComponentModel.DataAnnotations.Compare("Password")]
    [DataType(DataType.Password)]
    public string PasswordConfirm { get; set; }
}

继承自 IdentitiyUSer 模型的模型

public class AppUser : IdentityUser
{
    public AppUser() { }
}

启动class

public void Configuration(IAppBuilder app)
    {
        app.CreatePerOwinContext<IdentificationContext>(IdentificationContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
        });
    }

有异常输出

您需要在 web.config

中添加设置 (owin:AutomaticAppStartup)

<add key="owin:AutomaticAppStartup" value="true"/>

如果仍然不起作用，请添加以下设置以指定您的启动 class。这是因为 Startup class 的默认约定是 [AssemblyName].Startup。如果您不再遵循该约定，则需要在 Web.Config.

中指定您的 Startup class 的全名

<add key="owin:AppStartup" value="[Namespace].Startup, [AssemblyName]" />

希望对您有所帮助。
