.Net Core 3.1身份自定义UserManager FindByIdAsync方法

如何解决.Net Core 3.1身份自定义UserManager FindByIdAsync方法

我一直在尝试使用UserManager和RoleManager。我实现了具有 int主键的身份类。

例如，当我想使用UserManager FindByIdAsync方法时，它仍然是必需的字符串userId参数，但是我想使用int参数。我该如何更改？实际上，我之前没有自定义UserManager或UserStore。

除了所有这些，我还使用LinqToDB.Identity。

 var appUser = _userService.FindByIdAsync(); //must be used an int parameter

这是我的AppUser类。

public class AppUser : IdentityUser<int>,IEntity
{
   [required,Identity]
   [Key]
   public override int Id { get => base.Id; set => base.Id = value; }
   public DateTime CreatedDate { get; set; }
   public DateTime? ModifiedDate { get; set; }

   public int? CreatedBy { get; set; }
   public int? ModifiedBy { get; set; }
   public int? StatusId { get; set; }
}

这是我的AddLinqToDBStores实现。

/// <summary>
/// Adds authentication service
/// </summary>
/// <param name="services">Collection of service descriptors</param>
public static void AddDevPlatformAuthentication(this IServiceCollection services,IConfiguration configuration)
{
    services.AddIdentity<AppUser,AppRole>(options =>
    {
        options.Password.requiredigit = true;
        options.Password.requiredLength = 4;
        options.Password.RequireNonAlphanumeric = false;
        options.Password.RequireUppercase = true;
        options.Password.RequireLowercase = false;

        options.User.RequireUniqueEmail = true;
        options.SignIn.RequireConfirmedEmail = false;

        //Todo
        //options.User.RequireUniqueEmail = true; 
        //options.Lockout.MaxFailedAccessAttempts = 5;
        //options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(3);

    }).AddLinqToDBStores<int,AppUserClaim,AppUserRole,AppUserLogin,AppUserToken,AppRoleClaim>(new
    IdentityConnectionFactory(new sqlServerDataProvider(ProviderName.sqlServer,sqlServerVersion.v2017),"sqlServerIdentity",DataSettingsManager.LoadSettings().ConnectionString))
    .AddUserStore<LinqToDB.Identity.UserStore<int,AppUser,AppRole,AppUserToken>>()
    .AddUserManager<UserManager<AppUser>>()
    .AddRoleManager<RoleManager<AppRole>>()
        .AddDefaultTokenProviders();

    services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();

    // Uncomment the following lines to enable logging in with third party login providers

    JwtTokenDeFinitions.LoadFromConfiguration(configuration);
    services.ConfigureJwtAuthentication();
    services.ConfigureJwtAuthorization();
}

_userManager.FindByIdAsync（）如我所说，我需要对所有userManager和roleManager方法使用 int参数。

我该如何处理？
