asp.net core系列 47 Identity 自定义用户数据

一.概述

接着上篇的WebAppIdentityDemo项目，将自定义用户数据添加到Identity DB，自定义扩展的用户数据类应继承IdentityUser类，文件名为Areas / Identity / Data / {项目名称}User.cs。自定义的用户数据模型属性需要使用[PersonalData]来修饰，以便自动下载和删除。使数据能够下载和删除有助于满足GDPR要求。

　　1.1 自定义用户数据类 WebAppIdentityDemo.Areas.Identity.Data。

    public class WebAppIdentityDemoUser:IdentityUser
    {
        /// <summary>
        /// Full name
        /// </summary>
        [PersonalData]
        public string Name { get; set; }

        /// <summary>
        /// Birth Date
        /// </summary>
        [PersonalData]
        public DateTime DOB { get; set; }
    }

　　　　使用属性修饰PersonalData特性是：

　　　　　　使用Areas/Identity/Pages/Account/Manage/DeletePersonalData.cshtml 页调用UserManager.Delete

　　　　　　使用Areas/Identity/Pages/Account/Manage/DownloadPersonalData.cshtml 页下载用户数据

　　1.2 修改IdentityHostingStartup

　　　　将Startup中有关identity的服务移到该文件中，好集中管理。

   public class IdentityHostingStartup : IHostingStartup
    {
        public void Configure(IWebHostBuilder builder)
        {
            builder.ConfigureServices((context, services) => {
                services.AddDbContext<ApplicationDbContext>(options =>
                    options.UseSqlServer(
                        context.Configuration.GetConnectionString("DefaultConnection")));

                services.AddDefaultIdentity<WebAppIdentityDemoUser>()
                   .AddDefaultUI()
                   .AddEntityFrameworkStores<ApplicationDbContext>();

                services.Configure<IdentityOptions>(options =>
                {
                    // Password settings.
                    options.Password.RequireDigit = true;
                    options.Password.RequireLowercase = true;
                    options.Password.RequireNonAlphanumeric = true;
                    options.Password.RequireUppercase = true;
                    options.Password.RequiredLength = 6;
                    options.Password.RequiredUniqueChars = 1;

                    // Lockout settings.
                    options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(5);
                    options.Lockout.MaxFailedAccessAttempts = 5;
                    options.Lockout.AllowedForNewUsers = true;

                    // User settings.
                    options.User.AllowedUserNameCharacters =
                    "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+";
                    options.User.RequireUniqueEmail = false;
                });

                services.ConfigureApplicationCookie(options =>
                {
                    // Cookie settings
                    options.Cookie.HttpOnly = true;
                    options.ExpireTimeSpan = TimeSpan.FromMinutes(5);

                    options.LoginPath = $"/Identity/Account/Login";
                    options.LogoutPath = $"/Identity/Account/Logout";
                    options.AccessDeniedPath = $"/Identity/Account/AccessDenied";
                });
            });
        }
    }

　　1.3 修改DbContext上下文

    // public class ApplicationDbContext : IdentityDbContext
    public class ApplicationDbContext : IdentityDbContext<WebAppIdentityDemoUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }
        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            // Customize the ASP.NET Core Identity model and override the defaults if needed.
            // For example, you can rename the ASP.NET Core Identity table names and more.
            // Add your customizations after calling base.OnModelCreating(builder);
        }
    }

　　1.4 数据库版本迁移

　　PM> Add-Migration IdentitySchema2
　　PM> Update-Database IdentitySchema2

　　1.5 更新注册页面

　　　　在开发中，会员系统要重用修改的页面，把IdentityUser 改成WebAppIdentityDemoUser。如果没改将报错：未解析到服务IdentityUser。红色部分为修改的代码

    [AllowAnonymous]
    public class RegisterModel : PageModel
    {
        // private readonly SignInManager<IdentityUser> _signInManager;
        //private readonly UserManager<IdentityUser> _userManager;
        private readonly SignInManager<WebAppIdentityDemoUser> _signInManager;
        private readonly UserManager<WebAppIdentityDemoUser> _userManager;

        private readonly ILogger<RegisterModel> _logger;
        private readonly IEmailSender _emailSender;

        public RegisterModel(
            UserManager<WebAppIdentityDemoUser> userManager,
            SignInManager<WebAppIdentityDemoUser> signInManager,
            ILogger<RegisterModel> logger,
            IEmailSender emailSender)
        {
            _userManager = userManager;
            _signInManager = signInManager;
            _logger = logger;
            _emailSender = emailSender;
        }

        [BindProperty]
        public InputModel Input { get; set; }

        public string ReturnUrl { get; set; }

        public class InputModel
        {
            [Required]
            [DataType(DataType.Text)]
            [Display(Name = "Full name")]
            public string Name { get; set; }

            [Required]
            [Display(Name = "Birth Date")]
            [DataType(DataType.Date)]
            public DateTime DOB { get; set; }


            [Required]
            [EmailAddress]
            [Display(Name = "Email")]
            public string Email { get; set; }

            [Required]
            [StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
            [DataType(DataType.Password)]
            [Display(Name = "Password")]
            public string Password { get; set; }

            [DataType(DataType.Password)]
            [Display(Name = "Confirm password")]
            [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
            public string ConfirmPassword { get; set; }
        }

        public void OnGet(string returnUrl = null)
        {
            ReturnUrl = returnUrl;
        }

        public async Task<IActionResult> OnPostAsync(string returnUrl = null)
        {
            returnUrl = returnUrl ?? Url.Content("~/");
            if (ModelState.IsValid)
            {
                // var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
                var user = new WebAppIdentityDemoUser
                {
                    UserName = Input.Email,
                    Email = Input.Email,
                    Name = Input.Name,
                    DOB = Input.DOB
                };
                var result = await _userManager.CreateAsync(user, Input.Password);
                if (result.Succeeded)
                {
                    _logger.LogInformation("User created a new account with password.");

                    var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
                    var callbackUrl = Url.Page(
                        "/Account/ConfirmEmail",
                        pageHandler: null,
                        values: new { userId = user.Id, code = code },
                        protocol: Request.Scheme);

                    await _emailSender.SendEmailAsync(Input.Email, "Confirm your email",
                        $"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");

                    await _signInManager.SignInAsync(user, isPersistent: false);
                    return LocalRedirect(returnUrl);
                }
                foreach (var error in result.Errors)
                {
                    ModelState.AddModelError(string.Empty, error.Description);
                }
            }

            // If we got this far, something failed, redisplay form
            return Page();
