在.Net Core 中设置 UserTokenProvider

Question

我正在将现有的 Mvc 应用程序转换为.Net Core，问题是初始化

DataProtectorTokenProvider

在 Mvc 应用程序中它属于

Microsoft.Owin.Security.DataProtection.IDataProtector

下面的代码用于在 Mvc 中生成UserTokenProvider

public void ConfigureAuth(IAppBuilder app)
{
    app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
}

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
{
    var manager = new ApplicationUserManager(new MySqlUserStore<ApplicationUser>());
    //var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
    // Configure validation logic for usernames
    manager.UserValidator = new UserValidator<ApplicationUser>(manager)
    {
        AllowOnlyAlphanumericUserNames = false,
        // RequireUniqueEmail = false
    };

    // Configure validation logic for passwords
    manager.PasswordValidator = new PasswordValidator
    {
        RequiredLength = 2,
        RequireNonLetterOrDigit = false,
        RequireDigit = false,
        RequireLowercase = false,
        RequireUppercase = false
    };

    // Configure user lockout defaults
    manager.UserLockoutEnabledByDefault = true;
    manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(50);
    manager.MaxFailedAccessAttemptsBeforeLockout = 5;

    // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
    // You can write your own provider and plug it in here.
    manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser>
    {
        MessageFormat = "Your security code is {0}"
    });
    manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
    {
        Subject = "Security Code",
        BodyFormat = "Your security code is {0}"
    });
    manager.EmailService = new EmailService();
    manager.SmsService = new SmsService();
    var dataProtectionProvider = options.DataProtectionProvider;
    if (dataProtectionProvider != null)
    {
        manager.UserTokenProvider = 
            new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
    }
    return manager;
}

这会自动初始化DataProtectorTokenProvider

但不再使用 In.Net Core Owin。

现在请告诉我如何初始化

在 .net 内核中不使用 Owin？

Answer 1

您必须使用TokenOptions.ProviderMap 属性并使用您自己的 TokenProvider 并像这样注册它。

services.AddIdentity<User, Role>(options => {
options.Tokens.ProviderMap.Add("ASP.NET Identity", new TokenProviderDescriptor(typeof(MyTokenProvider)));
})
.AddTokenProvider<MyTokenProvider>(nameof(MyTokenProvider));

以及 ConfigureServices 中的可选配置：

services.Configure<DataProtectionTokenProviderOptions>(o =>
    {
        o.Name = "ASP.NET Identity";
        o.TokenLifespan = TimeSpan.FromHours(1);
    });

检查此线程以获取更多信息：

但是， 也有人评论说添加.AddDefaultTokenProviders()也可能会解决问题，因此您可以先尝试一下。

 services.AddIdentity<User, UserRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

Answer 2

这个答案能回答你的问题吗？

它指出，要配置您的 UserTokenProvider，您可以在ConfigureServices(IServiceCollection services)方法的StartUp class 中添加此代码：

services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddDefaultTokenProviders();
