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。
[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();
}
}
@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" />
}
启动程序，运行注册页，保存成功后，查看数据库，如下所示：
1.6 其它相关页修改
下面这些最基本的页面，都需要把IdentityUser 改成WebAppIdentityDemoUser。
登录页 /Identity/Account/Login
注册页 Identity/Account/Register
会员管理后台主页 /Identity/Account/Manage/index
个人资料页 /Identity/Account/Manage/PersonalData
个人资料删除 /Identity/Account/Manage/DeletePersonalData
个人资料下载/Identity/Account/Manage/ DownloadPersonalData.cshtml
分部页 _ManageNav.cshtml
下面是 Account/Manage/Index.cshtml 页，已经加上自定义的二个用户字段信息，具体更新代码见官网
下面是/Identity/Account/Manage/PersonalData.cshtml 页，已经可以下载和删除用户数据
