尝试激活 Identity.IdentityUserManager 时无法解析类型 Identity.IdentityUserStore 的服务

Question

我正在尝试在一个项目中使用 ASP.NET Core Identity 3.0，该项目的现有数据库未使用 Identity。因此我需要做一些定制，因为我想做一些更复杂的操作。

这是使用 .NET Core 3.1 完成的

但是当我运行现在的解决方案时，我得到了这两个例外：

InvalidOperationException：验证服务描述符时出错 'ServiceType: Microsoft.AspNetCore.Identity.ISecurityStampValidator Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.SecurityStampValidator`1[ForumProject.Data.Identity.IdentityForumUser]'：尝试激活 'ForumProject.Data.Identity.IdentityUserManager'. 时无法解析类型 'ForumProject.Data.Identity.IdentityUserStore' 的服务

InvalidOperationException：尝试激活 'ForumProject.Data.Identity.IdentityUserManager'.

时无法解析类型 'ForumProject.Data.Identity.IdentityUserStore' 的服务

我不知道我做错了什么，在我添加 UserStore 之前它一直在工作，所以我一定是创建错误，但到目前为止我找不到问题所在。

我在 startup.cs 的 ConfigureServices 中设置了这个：

public void ConfigureServices(IServiceCollection services)
{
    services.AddScoped<IPasswordHasher<IdentityForumUser>, IdentityPasswordHasher>();

    services.AddDbContext<DatabaseContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("ForumDatabase")));
    services.AddDbContext<IdentityDatabaseContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("ForumDatabase")));
    //services.AddIdentity<AppUser, IdentityRole>().AddEntityFrameworkStores<AppIdentityDbContext>().AddDefaultTokenProviders();
    services.AddIdentity<IdentityForumUser, IdentityForumRole>(options =>
        {
            options.SignIn.RequireConfirmedAccount = false;
            options.Password.RequiredLength = 2;
            options.Password.RequireDigit = false;
            options.Password.RequireLowercase = false;
            options.Password.RequiredUniqueChars = 0;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = false;
        })
        //.AddRoles<IdentityForumRole>()
        .AddUserStore<IdentityUserStore>()
        .AddUserManager<IdentityUserManager>()
        //.AddSignInManager<IdentitySignInManager>()
        .AddEntityFrameworkStores<IdentityDatabaseContext>();

    services.AddMvc();
    services.AddControllersWithViews();
    services.AddRazorPages();
}

这是 IdentityForumUser、IdentityForumRole、IdentityDatabaseContext：

public class IdentityForumUser : IdentityUser<int>
{
    [Column("Username")]
    public override string UserName { get; set; }

    [Column("Password")]
    public override string PasswordHash { get; set; }

    public int ThemeId { get; set; } = 1; /// TODO: Make it set to the picked default one

    public int ChatStatus { get; set; } = 0;

    public DateTime RegistrationDate { get; set; } = DateTime.UtcNow;

    public bool DynamicMode { get; set; } = false;

    public DateTime LastActivity { get; set; } = DateTime.UtcNow;
}

public class IdentityForumRole : IdentityRole<int>
{
}

public class IdentityDatabaseContext : IdentityDbContext<IdentityForumUser, IdentityForumRole, int>
{
    public IdentityDatabaseContext(DbContextOptions<IdentityDatabaseContext> options)
        : base(options)
    {
    }

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

        builder.Entity<IdentityForumUser>()
            .Ignore(c => c.LockoutEnd)
            .Ignore(c => c.TwoFactorEnabled)
            .Ignore(c => c.PhoneNumberConfirmed)
            .Ignore(c => c.PhoneNumber)
            .Ignore(c => c.ConcurrencyStamp)
            .Ignore(c => c.EmailConfirmed)
            .Ignore(c => c.NormalizedEmail)
            //.Ignore(c => c.NormalizedUserName)
            .Ignore(c => c.LockoutEnabled)
            .Ignore(c => c.AccessFailedCount)
            .ToTable("Users");
        builder.Entity<IdentityForumRole>()
            .Ignore(c => c.ConcurrencyStamp)
            .ToTable("Roles");
    }
}

这里是 IdentityUserStore，IdentityUserManager：

public class IdentityUserStore : UserStore<IdentityForumUser, IdentityForumRole, IdentityDatabaseContext, int>
{
    public IdentityUserStore(IdentityDatabaseContext context, IdentityErrorDescriber describer = null) : base(context, describer)
    {
    }
}

public class IdentityUserManager : UserManager<IdentityForumUser>
{
    public IdentityUserManager(IdentityUserStore store, IOptions<IdentityOptions> optionsAccessor,
        IPasswordHasher<IdentityForumUser> passwordHasher, IEnumerable<IUserValidator<IdentityForumUser>> userValidators,
        IEnumerable<IPasswordValidator<IdentityForumUser>> passwordValidators, ILookupNormalizer keyNormalizer,
        IdentityErrorDescriber errors, IServiceProvider services, ILogger<IdentityUserManager> logger)
        : base(store, optionsAccessor, passwordHasher, userValidators, passwordValidators, keyNormalizer, errors, services, logger)
    {
    }

    public override bool SupportsUserClaim
    {
        get
        {
            ThrowIfDisposed();
            return false;
        }
    }
}

这是 IdentityPasswordHasher，但只是其中的一部分，我将注释掉逻辑本身，我不确定这是否相关：

public class IdentityPasswordHasher : PasswordHasher<IdentityForumUser>
{
    private readonly PasswordHasherCompatibilityMode _compatibilityMode;

    public IdentityPasswordHasher(IOptions<PasswordHasherOptions> optionsAccessor = null)
        : base(optionsAccessor)
    {
        var options = optionsAccessor?.Value ?? new PasswordHasherOptions();

        _compatibilityMode = options.CompatibilityMode;
    }

    public override string HashPassword(IdentityForumUser user, string password)
    {
        // custom hashing code
    }

    public override PasswordVerificationResult VerifyHashedPassword(IdentityForumUser user, string hashedPassword, string providedPassword)
    {
        // custom verification code
    }
}

Answer 1

在 IdentityUserManager 的构造函数中，我将其更改为使用 IUserStore<IdentityForumUser> store，而不是 IdentityUserStore store（我的自定义 class）。

这使它工作并且仍然使用我的自定义商店 class。但是，我不高兴我不能明确，因为它使代码更容易理解。如果有明确的方法，也请回答。
