如何在 ASP.NET Core 中为 React SPA 自定义身份控制器？

Question

我关注了官方tutorial 以获取 Microsoft SPA 的身份。但是现在我的用户表中需要更多数据。所以我关注了customise identity tutorial，但那是针对剃须刀页面的。现在，当我打开我的脚手架反应应用程序时，我看不到任何要自定义的控制器。我可以从模型中添加新数据，但是如何在 react SPA 中自定义控制器以供用户注册？

您需要自定义现有的Identity接口：

例如：

using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.WebUtilities;
using Microsoft.Extensions.Configuration;
using Microsoft.IdentityModel.Tokens;
using shadow.Models;
using shadow.Shared;
using System;
using System.IdentityModel.Tokens.Jwt;
using System.Linq;
using System.Security.Claims;
using System.Text;
using System.Threading.Tasks;

namespace shadow.Services
{

    public interface IUserService
    {

        Task<UserManagerResponse> RegisterUserAsync(RegisterViewModel model);
        Task<UserManagerResponse> LoginUserAsync(LoginViewModel model);
        Task<UserManagerResponse> LogoutUserAsync(LoginViewModel model);
        Task<UserManagerResponse> ConfirmEmailAsync(string userId, string token);
        Task<UserManagerResponse> ForgetPasswordAsync(string email);
        Task<UserManagerResponse> ResetPasswordAsync(ResetPasswordViewModel model);
    }

    public class UserService : IUserService
    {
        private UserManager<ApplicationUser> _userManger;
        private IConfiguration _configuration;
        private IMailService _mailService;

        public UserService(UserManager<ApplicationUser> userManager, IConfiguration configuration, IMailService mailService)
        {
            _userManger = userManager;
            _configuration = configuration;
            _mailService = mailService;
        }
