在 Identity Asp.net core 3 MVC 中创建服务 IUserStore 时出错

Update

请参阅下面的更新。

我问过一个之前的 stackoverflow 问题 https://stackoverflow.com/questions/58654400/store-does-not-implement-iuserrolestoretuser-usermanagertuser-getuserrolesto最近，但在实施以下两个地方建议的解决方案后，我遇到了一个问题ASP.NET Core 中的身份模型自定义 https://learn.microsoft.com/en-us/aspnet/core/security/authentication/customize-identity-model?view=aspnetcore-3.0 and ASP.NET Core Identity 的自定义存储提供程序 https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-custom-storage-providers?view=aspnetcore-3.0。我只是无法让解决方案发挥作用。我已经实现了扩展IdentityUser按照建议并延长IdentityRole。我已经实施了IUserPasswordStore and IUserRoleStore and IUserStore for UserStore我已经实施了IRoleStore for RoleStore。我还实现了新的 dbContextApplicationDbContext它实现了IdentityDbContext。构造函数不接受参数存在问题，因此我实现了一个新的构造函数。我不确定这是否正确。

然而，这似乎无关紧要，因为我在调用时在 Program.cs 的 Main 方法中收到错误

CreateHostBuilder(args).Build().Run(); 

而且误差很大。我把它放在最后了。在线搜索错误的部分并没有提供关于我正在做的事情的任何想法，并且由于我是 ASP.NET Core 3 和 Identity 的新手，所以我被难住了。

这是我到目前为止的代码。

配置服务 method

public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddMvc(options =>
        {
            var policy = new AuthorizationPolicyBuilder().RequireAuthenticatedUser().Build();
            options.Filters.Add(new AuthorizeFilter(policy));
        options.EnableEndpointRouting = false;
        });

        services.AddDbContext<EntitiesModel>(options => options.UseSqlServer(
            Configuration["Data:ConnectionStrings:XXXXDbConnection"]));
        services.AddIdentity<UserViewModel,RoleViewModel>().AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders().AddRoles<RoleViewModel>(); ;
        services.AddTransient<IUserStore<UserViewModel>, UserStore>();
        services.AddTransient<IRoleStore<RoleViewModel>, RoleStore>();
        services.ConfigureApplicationCookie(options =>
        {
            options.LoginPath = "/Login";
            options.LogoutPath = "/Logout";
        });
    }

应用程序数据库上下文- 这些都在同一个命名空间中

public class IdentityDbContext
    : IdentityDbContext<IdentityUser, IdentityRole, string>
{
    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {
    }
}

public class IdentityDbContext<TUser>
    : IdentityDbContext<TUser, IdentityRole, string>
    where TUser : IdentityUser
{
    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {
    }
}

// Uses the built-in Identity types except with custom User and Role types
// The key type is defined by TKey
public class IdentityDbContext<TUser, TRole, TKey> : IdentityDbContext<
    TUser, TRole, TKey, IdentityUserClaim<TKey>, IdentityUserRole<TKey>,
    IdentityUserLogin<TKey>, IdentityRoleClaim<TKey>, IdentityUserToken<TKey>>
    where TUser : IdentityUser<TKey>
    where TRole : IdentityRole<TKey>
    where TKey : IEquatable<TKey>
{
    private DbContextOptions<ApplicationDbContext> options;
    //private string nameOrConnectionString;

    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options)
    {
        this.options = options;
    }

}

public abstract class IdentityDbContext<
        TUser, TRole, TKey, TUserClaim, TUserRole, TUserLogin, TRoleClaim, TUserToken>
    : IdentityUserContext<TUser, TKey>
    where TUser : IdentityUser<TKey>
    where TRole : IdentityRole<TKey>
    where TKey : IEquatable<TKey>
    where TUserRole : IdentityUserRole<TKey>
{

}
public class ApplicationDbContext : IdentityDbContext<UserViewModel,RoleViewModel,int>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

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

        modelBuilder.Entity<UserViewModel>(b =>
        {               
            b.HasMany(e => e.UserRoles)
                .WithOne()
                .HasForeignKey(ur => ur.Id)
                .IsRequired();
        });
        modelBuilder.Entity<UserViewModel>(b =>
        {
            b.ToTable("T_CustomerContacts");
        });
        modelBuilder.Entity<RoleViewModel>(b =>
        {
            b.ToTable("T_LoginRoles");
        });
        modelBuilder.Entity<UserRoleViewModel>(b =>
        {
            b.ToTable("T_CustomerContactRole");
        });         
        modelBuilder.Entity<RoleViewModel>(b =>
        {
            b.HasMany(e => e.UserRoles)
                .WithOne(e => e.Role)
                .HasForeignKey(ur => ur.RoleId)
                .IsRequired();
        });
    }
}

用户视图模型

public class UserViewModel : IdentityUser<int>
{

用户角色视图模型

public class UserRoleViewModel : IdentityUserRole<int>
{

角色视图模型

public class RoleViewModel : IdentityRole<int>
{   

角色库

public class RoleStore : IRoleStore<RoleViewModel>
{

用户存储

public class UserStore : IUserStore<UserViewModel>, IUserPasswordStore<UserViewModel>, IUserRoleStore<UserRoleViewModel>
{

我必须补充一点，这是我尝试过的最终配置。我尝试了很多组合和解决方案。 部分错误如下

启动应用程序时发生错误。 AggregateException：无法构造某些服务（验证服务描述符'ServiceType时出错：Microsoft.AspNetCore.Identity.IUserStore1[TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore4[TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext,System.Int32]'：无法解析类型的服务尝试激活“Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore”时出现“TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext”4[TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext,System.Int32]'.)

Update

我回到了上一个问题的开始位置，但通过颠倒以下顺序解决了上述错误

    services.AddTransient<IUserStore<UserViewModel>, UserStore>();
        services.AddTransient<IRoleStore<RoleViewModel>, TrussCorp.CustomerPortal.Identity.RoleStore>();
        services.AddIdentity<UserViewModel,RoleViewModel>().AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders().AddRoles<RoleViewModel>();

但正如现在所说，我得到了Store 未实现 IUserRoleStore UserManager.GetUserRoleStore() https://stackoverflow.com/questions/58654400/store-does-not-implement-iuserrolestoretuser-usermanagertuser-getuserrolesto错误让我回到了第一个方向。

我对其他开发人员的建议是，如果您在互联网上找不到类似的问题，那么您正在做一些愚蠢而独特的事情。

解决方案是改变这个

public class UserStore : IUserStore<UserViewModel>, IUserPasswordStore<UserViewModel>, IUserRoleStore<UserRoleViewModel>
{

to this

public class UserStore : IUserStore<UserViewModel>, IUserPasswordStore<UserViewModel>, IUserRoleStore<UserViewModel>
{
