Identity UserManager CreateAsync 不写入数据库

Question

它不会给出任何错误或警告，但不会插入数据库。 好像只有memory。

此外，UserManager 的 FindByNameAsync 无法检查已在数据库中创建的用户，可能出于同样的原因。

这是我的 Controller：

public class AccountController : Controller
    {
        private readonly UserManager<User> _userManager;
        private readonly SignInManager<User> _signInManager;

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

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

        [HttpPost]
        public async Task<IActionResult> Login(User user)
        {
            if (ModelState.IsValid)
            {
                var result = await _userManager.CreateAsync(user, user.Password);

                if (result.Succeeded)
                {
                    Console.WriteLine("OK");
                }

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

                if (username != null)
                {
                    //sign in
                    var signInResult = await _signInManager.PasswordSignInAsync(user.UserName, user.Password, false, false);

                    if (signInResult.Succeeded)
                    {
                        return RedirectToAction("Index", "ProjectCampaign");
                    }
                }
            }
            return View();
        }

        public async Task<IActionResult> Logout()
        {
            await _signInManager.SignOutAsync();

            return RedirectToAction("Login", "Account");
        }
    }

                config.ExpireTimeSpan = TimeSpan.FromMinutes(1);
            });

            services.AddScoped<RandomContext>();

            services.AddControllersWithViews().AddRazorRuntimeCompilation();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {

            }
            else

                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();

                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }

我有类似的问题 - AspNetCore.Identity.UserManager没有抛出任何错误，但没有在CreateAsync(user, password)条目写入数据库。 但是，当我调试UserManager时，我可以看到PasswordValidators数组中只有一个条目。

基本上，输入的密码不够复杂。 更改了密码，一切正常。
