Question

.NET Core 2.2应用程序出现问题。我向我的应用程序添加了身份验证和用户实体，现在我的应用程序在启动时引发异常。当我尝试添加迁移时，会引发另一个异常。

当我尝试添加初始迁移时：

无法添加实体类型“ AppUser”的种子实体，因为为属性“ Id”提供的值不是“ int”类型。考虑使用'DbContextOptionsBuilder.EnableSensitiveDataLogging'来查看涉及的属性值。

当我尝试启动我的应用程序时：

无法添加实体类型“ AppUser”的种子实体，因为为物业提供的值'95ee39c2-a865-4272-8b67-da590fb4b80c' “ Id”不是“ int”类型。

我不知道我做错了什么。我尝试更改了几个小时，但没有成功。

Startup.cs -ConfigureServices方法

    services.AddDbContext<ResumeContext>(options => 
        options
            .UseSqlServer(Configuration.GetConnectionString("ResumeConnection"))
            .EnableSensitiveDataLogging()
        );

    var builder = services.AddIdentityCore<AppUser>(o =>
    {
        o.Password.RequireDigit = false;
        o.Password.RequireLowercase = false;
        o.Password.RequireUppercase = false;
        o.Password.RequireNonAlphanumeric = false;
        o.Password.RequiredUniqueChars = 0;
        o.Password.RequiredLength = 6;
    });

    builder = new IdentityBuilder(builder.UserType, typeof(AppRole), builder.Services);
    builder.AddEntityFrameworkStores<ResumeContext>().AddDefaultTokenProviders();

SeedData.cs

public static class SeedData
{
    public static IWebHost SeedAdminUser(this IWebHost webHost)
    {
        using (var scope = webHost.Services.CreateScope())
        {
            var userManager = scope.ServiceProvider.GetRequiredService<UserManager<AppUser>>();
            var roleManager = scope.ServiceProvider.GetRequiredService<RoleManager<AppRole>>();

            if (userManager.Users.Any(u => u.Email == "admin@domain.com")) return webHost;

            roleManager.CreateAsync(new AppRole { Name = AppRole.Admin }).Wait();

            userManager.CreateAsync(new AppUser { UserName = "Admin", Email = "admin@domain.com" }, "CCZtE2XpqXbSs5B").Wait();

            userManager.AddToRoleAsync(userManager.FindByEmailAsync("admin@domain.com").Result, AppRole.Admin).Wait();
        }

        return webHost;
    }
}

AppUser.cs

public class AppUser : IdentityUser<int>
{
    // TODO: This will be extended in future
}

User.cs

public class User
{
    public int Id { get; set; }

    public int AppUserId { get; set; }

    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string Email { get; set; }

    public string Phone { get; set; }

    public string PostalCode { get; set; } 

    public DateTime CreationDate { get; set; }

    public DateTime? ModifyDate { get; set; }

    public long? FacebookId { get; set; }

    public AppUser AppUser { get; set; }
}

Program.cs

public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args)
            .Build()
            .SeedAdminUser()
            .Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>();
}

Context.cs

public class ResumeContext : IdentityDbContext<AppUser, AppRole, int>
{
    public ResumeContext(DbContextOptions options) : base(options) { }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Configure("Resume.Infrastructure.Data");
    }
}

有人知道我在做什么错吗？以及如何正确配置身份和种子管理员用户？

Answer 1

确保您的ResumeContext继承自使用IdentityDbContext的{{1}}。

您可以在此处找到如何通过基于IdentityUser<int>的{{1}}配置自定义IdentityDbContext的示例：Your Identity based DB context should look like this
