Question

我正在使用asp.Identity在我的应用程序中执行用户和角色模块。我创建像这样的用户

var user = new ApplicationUser() { UserName = name, Email = email };
IdentityResult result1 = ApplicationUserManager.AppUserManager.Create(user, password);

它创建了用户，问题是在应用程序管理器中它没有检查重复的电子邮件。我的应用程序管理器看起来像这样

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new EntityUserStore<ApplicationUser, Account, ApplicationRole, Role>());

        AppUserManager = manager;

        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };
        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
}

另一个问题是，如果我使用用户名登录它会起作用，但如果我使用emal则返回null。

 ApplicationUser user = UserManager.FindByEmail(email); // this returns null

有谁熟悉这个问题？

您的ApplicationUserManager.AppUserManager.Create不会验证电子邮件，因为您没有引用ApplicationUserManager上下文，如下所示：

var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>(); 
var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>(); 
var user = new ApplicationUser() { UserName = name, Email = email }; 
IdentityResult result = manager.Create(user, password); 
if (result.Succeeded)

以上示例var manager将包含ApplicationUserManager上下文，电子邮件的验证将由RequireUniqueEmail = true完成。
