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

以下代码用于在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

但在 .Net Core Owin 中不再使用。

现在请告诉我如何初始化

UserTokenProvider

在 .net Core 中不使用 Owin？

您必须使用 TokenOptions.ProviderMap Property 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 this thread 了解更多信息：

但是 someone also commented 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();

在 .Net Core 中设置 UserTokenProvider
