[Solution] ASP.NET Identity(2) 空的项目使用

在本节中，我将说明将ASP.NET Identity添加到现有的项目或者一个空项目。我将介绍你需要添加的Nuget和Class。此示例中，会使用LocalDB。

新建项目

新建1个MVC项目或者一个空的WebForm项目都可以，在这里我使用MVC5（with no authentication）。

using System.Linq;
using System.Web;
using EmptyMVC.Models.Account;
using System.Web.Mvc;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin.Security;

namespace EmptyMVC.Controllers
{
public class AccountController : Controller
{
public ActionResult Index()
{
return View(User);
}

public ActionResult LogOff()
{
var authenticationManager = HttpContext.GetOwinContext().Authentication;
authenticationManager.SignOut();
return Redirect("Login");
}

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

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model)
{
if (ModelState.IsValid)
{
var userStore = new UserStore<IdentityUser>();
var userManager = new UserManager<IdentityUser>(userStore);
var user = userManager.Find(model.Name, model.Pwd);
if (user != null)
{
var authenticationManager = HttpContext.GetOwinContext().Authentication;
var userIdentity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
authenticationManager.SignIn(userIdentity);
return LoginRedirect();
}
}
return View(model);
}

//
// GET: /Account/
public ActionResult Register()
{
return View();
}

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Register(RegisterModel model)
{
if (ModelState.IsValid)
{
// UserStore 默认构造函数会使用默认连接字符串: DefaultConnection
var userStore = new UserStore<IdentityUser>();
var manager = new UserManager<IdentityUser>(userStore);
var user = new IdentityUser() { UserName = model.Name };
var result = manager.Create(user, model.Pwd);
if (result.Succeeded)
{
var authenticationManager = HttpContext.GetOwinContext().Authentication;
var userIdentity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
authenticationManager.SignIn(new AuthenticationProperties() { }, userIdentity);
return LoginRedirect();
}
var erro = result.Errors.FirstOrDefault();
ModelState.AddModelError("", erro);
}
return View(model);
}

private ActionResult LoginRedirect()
{
var url = HttpContext.Request["returnurl"];
if (string.IsNullOrEmpty(url))
return Redirect(Url.Action("Index"));
return Redirect(url);
}
}
}

AccountController
这里需要一个LoginModel

public class LoginModel
{
[Required]
[Display(Name = "用户名")]
public string Name { get; set; }

[Required]
[StringLength(100, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "密码")]
public string Pwd { get; set; }
}

添加View

Login

@model EmptyMVC.Models.Account.LoginModel

@{
ViewBag.Title = "Login";
}

<h2>Login</h2>

@using (Html.BeginForm())
{
@Html.AntiForgeryToken()

<div class="form-horizontal">
<h4>LoginModel</h4>
<hr />
@Html.ValidationSummary(true)

<div class="form-group">
@Html.LabelFor(model => model.Name, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
</div>

<div class="form-group">
@Html.LabelFor(model => model.Pwd, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Pwd)
@Html.ValidationMessageFor(model => model.Pwd)
</div>
</div>

<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="登录" class="btn btn-default" />
</div>
</div>
</div>
}

<div>
@Html.ActionLink("回到首页", "Index")
</div>

@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

Index

@using Microsoft.AspNet.Identity
@model System.Security.Principal.IPrincipal
@{
ViewBag.Title = "Index";
}

<h2>Index</h2>
@if (Model.Identity.IsAuthenticated)
{
<h3>Hello @Model.Identity.GetUserName() ！</h3>
using (Html.BeginForm("LogOff","Account"))
{
Html.AntiForgeryToken();
<input type="submit" value="退出"/>
}
}
else
{
<ul class="nav navbar-nav navbar-right">
<li>@Html.ActionLink("注册", "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li>
<li>@Html.ActionLink("登录", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li>
</ul>
}
