如何在 ASP.NET Core 3.0 Preview 5 中将声明映射选项传递给 IdentityServerJwt？

Question

受到 an article on custom claims 的启发，我在我的身份服务器登录过程中添加了租户 ID 自定义声明，如下所示：

using System;
using System.Security.Claims;
using System.Threading.Tasks;
using MyNamespace.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.Extensions.Options;
using MyNamespace.Data;
using MyNamespace.Constants;

namespace MyNamespace.Factories
{

    public class TenantClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser>
    {
        public TenantClaimsPrincipalFactory(
            UserManager<ApplicationUser> userManager,
            IOptions<IdentityOptions> optionsAccessor)
            : base(userManager, optionsAccessor) {
        }

        // TODO: Remove hard binding to application db context
        protected override async Task<ClaimsIdentity> GenerateClaimsAsync(ApplicationUser user) {
            var identity = await base.GenerateClaimsAsync(user);
            var tenantId = ApplicationDbContext.DefaultTenantId;
            if (user.TenantId != Guid.Empty) {
                tenantId = user.TenantId;
            }
            identity.AddClaim(new Claim(CustomClaimTypes.TenantId, tenantId.ToString()));
            return identity;
        }
    } 

}

声明生成方法在登录时执行，并将声明添加到身份中，所以这部分看起来没问题。后来我尝试在我的租户提供商服务中读出声明如下

using System;
using MyNamespace.Data;
using Microsoft.AspNetCore.Http;
using System.Security.Claims;
using System.Linq;
using MyNamespace.Constants;

namespace MyNamespace.Services
{

    public interface ITenantProvider
    {
        Guid GetTenantId();
    }

    public class TenantProvider : ITenantProvider
    {
        private IHttpContextAccessor _httpContextAccessor;

        public TenantProvider(IHttpContextAccessor httpContextAccessor
        {
            _httpContextAccessor = httpContextAccessor;
        }

        // TODO: Remove hard binding to application db context
        public Guid GetTenantId()
        {
            var userId = _httpContextAccessor.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier).Value;
            var user = _httpContextAccessor.HttpContext.User;
            var tenantId = _httpContextAccessor.HttpContext.User.FindFirst(CustomClaimTypes.TenantId).Value;    

            Guid tenantGuid = ApplicationDbContext.DefaultTenantId;
            Guid.TryParse(tenantId, out tenantGuid);

            return tenantGuid;
        }
    }

}

然而，据我了解，CustomClaimTypes.TenantId 所确定的声明是 not automatically mapped by the Identity server。我的问题是：如何映射

options.ClaimActions.MapUniqueJsonKey(CustomClaimTypes.TenantId, CustomClaimTypes.TenantId);

从 Startup.cs 开始，我将身份服务器添加到我的依赖项中：

services.AddAuthentication()
            .AddIdentityServerJwt();

所以，最后我得到了一个与我最初寻求的不同的解决方案。我没有像工厂创建的那样映射声明，而是遇到了。基本上，我所做的是以下内容。我实施了以下 ProfileService

namespace MyNamespace.Services
{

    public class ProfileService : IProfileService
    {
        protected UserManager<ApplicationUser> _userManager;

        public ProfileService(UserManager<ApplicationUser> userManager)
        {
            _userManager = userManager;
        }

        public async Task GetProfileDataAsync(ProfileDataRequestContext context)
        {
            var user = await _userManager.GetUserAsync(context.Subject);

            var claims = new List<Claim>
            {
                new Claim(CustomClaimTypes.TenantId, user.TenantId.ToString()),
            };

            context.IssuedClaims.AddRange(claims);
        }

        public async Task IsActiveAsync(IsActiveContext context)
        {
            var user = await _userManager.GetUserAsync(context.Subject);

            context.IsActive = (user != null) && user.IsActive;
        }
    }

}

然后，我在 Configure 的 DI 容器中添加了服务：

services.AddIdentityServer()
                .AddApiAuthorization<ApplicationUser, ApplicationDbContext>()
                .AddProfileService<ProfileService>();

services.AddAuthentication()
                .AddIdentityServerJwt();

所以，我仍然乐于让 AddIdentityServerJwt 设置 IdentityServer4，同时获得我的声明。
