c# - 带有 EF Core 的 ASP.NET Core 注册页面上的错误

Question

我正在使用Gill Cleeren 制作的使用 Visual Studio 2017 Pluralsight 构建您的第一个 ASP.NET Core 2.1 MVC 应用程序。

我打开了最后一章，其中包含完整的 Bethany's Pie Shop 应用程序。

在下一步中，我构建了解决方案，在包管理器控制台中键入 update-database 并运行该应用程序。

该应用程序正在运行，并且在我尝试注册用户名之前一直有效。

我不知道究竟是什么错误，但数据未在 AspNetUsers 表中注册。

您可以在下面找到AccountController.cs文件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Identity;
using BethanysPieShop.ViewModels;

// For more information on enabling MVC for empty projects, visit https://go.microsoft.com/fwlink/?LinkID=397860

namespace BethanysPieShop.Controllers
{
    public class AccountController : Controller
    {
        private readonly SignInManager<IdentityUser> _signInManager;
        private readonly UserManager<IdentityUser> _userManager;

        public AccountController(SignInManager<IdentityUser> signInManager, UserManager<IdentityUser> userManager)
        {
            _signInManager = signInManager;
            _userManager = userManager;
        }

        public IActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> Login(LoginViewModel loginViewModel)
        {
            if (!ModelState.IsValid)
                return View(loginViewModel);

            var user = await _userManager.FindByNameAsync(loginViewModel.UserName);

            if (user != null)
            {
                var result = await _signInManager.PasswordSignInAsync(user, loginViewModel.Password, false, false);
                if (result.Succeeded)
                {
                    return RedirectToAction("Index", "Home");
                }
            }

            ModelState.AddModelError("", "User name/password not found");
            return View(loginViewModel);
        }

        public IActionResult Register()
        {
            return View(new LoginViewModel());
        }

        [HttpPost]
        public async Task<IActionResult> Register(LoginViewModel loginViewModel)
        {
            if (ModelState.IsValid)
            {
                var user = new IdentityUser() { UserName = loginViewModel.UserName };
                var result = await _userManager.CreateAsync(user, loginViewModel.Password);

                if (result.Succeeded)
                {
                    return RedirectToAction("Index", "Home");
                }
            }
            return View(loginViewModel);
        }

        [HttpPost]
        public async Task<IActionResult> Logout()
        {
            await _signInManager.SignOutAsync();
            return RedirectToAction("Index", "Home");
        }
    }
}

请让我知道您是否需要其他文件。

你知道我该如何解决这个问题吗？

谢谢。

LE：看来我可以从数据库中检索信息。所以，我认为问题可能来自代码。我还将在Startup.cs文件下面发布：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using BethanysPieShop.Models;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.AspNetCore.Identity;

namespace BethanysPieShop
{
    public class Startup
    {
        public IConfiguration Configuration { get; }

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<AppDbContext>(options =>
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddIdentity<IdentityUser, IdentityRole>().AddEntityFrameworkStores<AppDbContext>();

            //services.AddTransient<IPieRepository, MockPieRepository>();
            services.AddTransient<IPieRepository, PieRepository>();
            services.AddTransient<IFeedbackRepository, FeedbackRepository>();

            services.AddMvc();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseDeveloperExceptionPage();
            app.UseStatusCodePages();
            app.UseStaticFiles();

            app.UseAuthentication();


            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}
