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

Question

更新

请参阅下面的更新。

我问了一个previous Whosebug question very recently, but I face an issue after implementing the suggested solutions from the following 2 places Identity model customization in ASP.NET Core and Custom storage providers for ASP.NET Core Identity。我只是无法使解决方案起作用。我已经按照建议实现了 IdentityUser 的扩展和 IdentityRole 的扩展。我已经为 UserStore 实现了 IUserPasswordStore 和 IUserRoleStore 以及 IUserStore，并且我已经为 RoleStore 实现了 IRoleStore。我还实现了新的 dbContext ApplicationDbContext，它实现了 IdentityDbContext。构造函数不接受参数存在一个问题，所以我实现了一个新的构造函数。我不确定这是否正确。

但这似乎无关紧要，因为我在调用

时在 Program.cs 的 Main 方法中遇到错误

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

而且错误很大。我把它放在最后了。在线搜索错误部分并没有提供关于我在做什么的任何想法，而且由于我是 ASP.NET Core 3 和 Identity 的新手，我很困惑。

这是我目前的代码。

ConfigureServices 方法

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";
        });
    }

ApplicationDbContext - 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();
        });
    }
}

UserViewModel

public class UserViewModel : IdentityUser<int>
{

UserRoleViewModel

public class UserRoleViewModel : IdentityUserRole<int>
{

RoleViewModel

public class RoleViewModel : IdentityRole<int>
{

角色库

public class RoleStore : IRoleStore<RoleViewModel>
{

用户商店

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

An error occurred while starting the application. AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: 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]': Unable to resolve service for type 'TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext' while attempting to activate '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]'.) (Error while validating the service descriptor 'ServiceType: Microsoft.AspNetCore.Identity.IRoleStore1[TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.EntityFrameworkCore.RoleStore3[TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext,System.Int32]': Unable to resolve service for type 'TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext' while attempting to activate 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.RoleStore3[TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext,System.Int32]'.) Microsoft.Extensions.DependencyInjection.ServiceProvider..ctor(IEnumerable serviceDescriptors, ServiceProviderOptions options)

更新

我回到了上一个问题的起点，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>();

但正如我现在所说的那样，我遇到了 Store does not implement IUserRoleStore UserManager.GetUserRoleStore() 错误，这让我回到了原点。

Answer 1

你能不能试着把这个添加到顶部？

services.AddIdentity<UserViewModel,RoleViewModel>().AddUserStore<UserStore>().AddRoleStore<RoleStore>();

Answer 2

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，那您就是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>
{

到这个

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