Question

我正在构建一个完全自定义的AspNetCore.Identity实现，因为我希望TKey全面System.Guid。尊敬的是，我已经为...派生了类型。

Role : IdentityRole<Guid, UserRole, RoleClaim>
RoleClaim : IdentityRoleClaim<Guid>
User : IdentityUser<Guid, UserClaim, UserRole, UserLogin>
UserClaim : IdentityUserClaim<Guid>
UserLogin : IdentityUserLogin<Guid>
UserRole : IdentityUserRole<Guid>
UserToken : IdentityUserToken<Guid>
ApplicationDbContext : IdentityDbContext<User, Role, Guid, UserClaim, UserRole, UserLogin, RoleClaim, UserToken>
ApplicationRoleManager : RoleManager<Role>
ApplicationRoleStore : RoleStore<Role, ApplicationDbContext, Guid, UserRole, RoleClaim>
ApplicationSignInManager : SignInManager<User>
ApplicationUserManager : UserManager<User>
**ApplicationUserStore** : UserStore<User, Role, ApplicationDbContext, Guid, UserClaim, UserRole, UserLogin, UserToken>

ApplicationUserStore是问题儿童！

实施

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class Role : IdentityRole<Guid, UserRole, RoleClaim>
    {
    }
}

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class UserRole : IdentityUserRole<Guid>
    {
    }
}

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class RoleClaim : IdentityRoleClaim<Guid>
    {
    }
}

// The problem is here...

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity;
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;
    using System.Security.Claims;

    public sealed class ApplicationUserStore : UserStore<User, Role, ApplicationDbContext, Guid, UserClaim, UserRole, UserLogin, UserToken>
    {
    }
}

错误

类型＆＃39; NewCo.Identity.Role＆＃39;不能用作类型参数＆＃39; TRole＆＃39;在通用类型或方法＆＃39; UserStore＆＃39;。那里没有隐含的参考转换来自＆＃39; NewCo.Identity.Role＆＃39;至＆＃39;＆Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityRole GT;＆＃39;

据我所知，除非这是一些（co / contra / in）差异问题，否则所有代码都会检查出来......我出了什么问题？

您的ApplicationUserStore最后也需要RoleClaim（不要忘记更新相关的NuGet包，否则您无法使用这些新添加内容）：

    ApplicationUserStore : UserStore<
            User, Role, ApplicationDbContext, 
            Guid, UserClaim, UserRole, 
            UserLogin, UserToken, RoleClaim>

另外，您的ApplicationRoleStore应提供如何创建RoleClaim，

protected override RoleClaim CreateRoleClaim(Role role, Claim claim)
{
    return new RoleClaim
    {
        RoleId = role.Id,
        ClaimType = claim.Type,
        ClaimValue = claim.Value
    };
}

ApplicationUserStore也应提供这些映射：

protected override UserClaim CreateUserClaim(User user, Claim claim)
{
    var userClaim = new UserClaim { UserId = user.Id };
    userClaim.InitializeFromClaim(claim);
    return userClaim;
}

protected override UserLogin CreateUserLogin(User user, UserLoginInfo login)
{
    return new UserLogin
    {
        UserId = user.Id,
        ProviderKey = login.ProviderKey,
        LoginProvider = login.LoginProvider,
        ProviderDisplayName = login.ProviderDisplayName
    };
}

protected override UserRole CreateUserRole(User user, Role role)
{
    return new UserRole
    {
        UserId = user.Id,
        RoleId = role.Id
    };
}

protected override UserToken CreateUserToken(User user, string loginProvider, string name, string value)
{
    return new UserToken
    {
        UserId = user.Id,
        LoginProvider = loginProvider,
        Name = name,
        Value = value
    };
}

然后将内置服务重定向到您的自定义服务：

services.AddScoped<UserStore<User, Role, ApplicationDbContext, int, UserClaim, UserRole, UserLogin, UserToken, RoleClaim>, ApplicationUserStore>();
services.AddScoped<UserManager<User>, ApplicationUserManager>();
services.AddScoped<RoleManager<Role>, ApplicationRoleManager>();
services.AddScoped<SignInManager<User>, ApplicationSignInManager>();
services.AddScoped<RoleStore<Role, ApplicationDbContext, int, UserRole, RoleClaim>, ApplicationRoleStore>();
services.AddScoped<IEmailSender, AuthMessageSender>();
services.AddScoped<ISmsSender, AuthMessageSender>();

现在介绍您的自定义服务：

services.AddIdentity<User, Role>(identityOptions =>
            {
             // ...
            }).AddUserStore<ApplicationUserStore>()
              .AddUserManager<ApplicationUserManager>()
              .AddRoleStore<ApplicationRoleStore>()
              .AddRoleManager<ApplicationRoleManager>()
              .AddSignInManager<ApplicationSignInManager>()
              // You **cannot** use .AddEntityFrameworkStores() when you customize everything
              //.AddEntityFrameworkStores<ApplicationDbContext, int>()
              .AddDefaultTokenProviders();

ASP.NET核心 - 自定义AspNetCore.Identity实现不起作用
