一.概述

???????? 接著上篇的WebAppIdentityDemo項目，將自定義用戶數據添加到Identity DB，自定義擴展的用戶數據類應繼承IdentityUser類， 文件名為Areas / Identity / Data / {項目名稱}User.cs。自定義的用戶數據模型屬性需要使用[PersonalData]來修飾，以便自動下載和刪除。使數據能夠下載和刪除有助于滿足GDPR要求。

?

　　1.1 自定義用戶數據類?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; }}

　　　　使用屬性修飾PersonalData特性是：

　　　　　　使用Areas/Identity/Pages/Account/Manage/DeletePersonalData.cshtml 頁調用UserManager.Delete

　　　　　　使用Areas/Identity/Pages/Account/Manage/DownloadPersonalData.cshtml 頁下載用戶數據

?

　　1.2 修改IdentityHostingStartup

　　　　將Startup中有關identity的服務移到該文件中，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 settingsoptions.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 : IdentityDbContextpublic 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 數據庫版本遷移

　　PM> Add-Migration IdentitySchema2PM> Update-Database IdentitySchema2

　　1.5 更新注冊頁面

　　　　在開發中，會員系統要重用修改的頁面，把IdentityUser 改成WebAppIdentityDemoUser。如果沒改將報錯：未解析到服務IdentityUser。紅色部分為修改的代碼

[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 formreturn Page();}}

　　

@page @model RegisterModel @{ViewData["Title"] = "Register"; }<h1>@ViewData["Title"]</h1><div class="row"><div class="col-md-4"><form asp-route-returnUrl="@Model.ReturnUrl" method="post"><h4>Create a new account.</h4><hr /><div asp-validation-summary="All" class="text-danger"></div>

<div class="form-group"><label asp-for="Input.Name"></label><input asp-for="Input.Name" class="form-control" /><span asp-validation-for="Input.Name" class="text-danger"></span></div><div class="form-group"><label asp-for="Input.DOB"></label><input asp-for="Input.DOB" class="form-control" /><span asp-validation-for="Input.DOB" class="text-danger"></span></div>

<div class="form-group"><label asp-for="Input.Email"></label><input asp-for="Input.Email" class="form-control" /><span asp-validation-for="Input.Email" class="text-danger"></span></div><div class="form-group"><label asp-for="Input.Password"></label><input asp-for="Input.Password" class="form-control" /><span asp-validation-for="Input.Password" class="text-danger"></span></div><div class="form-group"><label asp-for="Input.ConfirmPassword"></label><input asp-for="Input.ConfirmPassword" class="form-control" /><span asp-validation-for="Input.ConfirmPassword" class="text-danger"></span></div><button type="submit" class="btn btn-primary">Register</button></form></div> </div>@section Scripts {<partial name="_ValidationScriptsPartial" /> }

　　　　啟動程序，運行注冊頁，保存成功后，查看數據庫，如下所示：

?

　　1.6 其它相關頁修改

　　　　下面這些最基本的頁面，都需要把IdentityUser 改成WebAppIdentityDemoUser。

　　　　　　登錄頁 /Identity/Account/Login

　　　　　　注冊頁 Identity/Account/Register

　　　　　　會員管理后臺主頁 /Identity/Account/Manage/index

　　　　　　個人資料頁 /Identity/Account/Manage/PersonalData

　　　　　　個人資料刪除 /Identity/Account/Manage/DeletePersonalData

　　　　　　個人資料下載/Identity/Account/Manage/ DownloadPersonalData.cshtml

　　　　　　分部頁 _ManageNav.cshtml

　　

　　下面是 Account/Manage/Index.cshtml 頁，已經加上自定義的二個用戶字段信息，具體更新代碼見官網

　　　　下面是/Identity/Account/Manage/PersonalData.cshtml 頁，已經可以下載和刪除用戶數據
