Asp.Net MVC 5使用Identity之简单的注册和登陆

来源：互联网发布：中国大学生网络党课编辑：程序博客网时间：2024/05/22 16:07

由于.Net MVC 5登陆和注册方式有很多种，但是Identity方式去实现或许会更简单更容易理解

首先新建一个项目

其次如下选择Empty和MVC的选项

然后打开NuGet包管理器分别安装几个包

EntityFramework
Microsoft.AspNet.Identity.Core
Microsoft.AspNet.Identity.EntityFramework
Microsoft.AspNet.Identity.Owin
Modernizr
Microsoft.Owin.Host.SystemWeb
Bootstrap

然后往Models文件夹里面添加ApplicationUser类，SignInModel类，SignUpModel类，ApplicationDbContext类，当然ApplicationDbContext类你也可以分到DbContext到另一个类库，我这是做演示用的，分层不用么这么明确

----------------------------------------------------------------------

ApplicationUser类

ApplicationDbContext类

SignInModel类

SignUpModel类

然后往App_Start文件夹里面添加ApplicationSignInManager类，ApplicationUserManager类，ApplicationUserStore类

---------------------------------------------------------------------

ApplicationUserManager类

ApplicationSignInManager类

ApplicationUserStore类

然后往Controller文件夹里面添加HomeController控制器，AccountController控制器

先往HomeController控制器里添加index视图

index视图代码

@using Microsoft.AspNet.Identity@{    ViewBag.Title = "Index";}<h2>Index</h2>@if (Request.IsAuthenticated){    using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))    {        @Html.AntiForgeryToken()        <p>Hello @User.Identity.GetUserName()</p>        <ul>            <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li>        </ul>    }}else{    <ul>        <li>            @Html.ActionLink("Login", "Login", "Account")        </li>        <li>            @Html.ActionLink("Register", "Register", "Account")        </li>    </ul>}

然后AccountController控制器代码

private ApplicationSignInManager signInManager;        private ApplicationUserManager userManager;        public ApplicationSignInManager SignInManager        {            get            {                return signInManager ?? HttpContext.GetOwinContext().Get<ApplicationSignInManager>();            }            private set            {                signInManager = value;            }        }        public ApplicationUserManager UserManager        {            get { return userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>(); }            private set            {                userManager = value;            }        }        [AllowAnonymous]        public ActionResult Login(string returnUrl)        {            ViewBag.ReturnUrl = returnUrl;            return View();        }        [HttpPost]        [AllowAnonymous]        [ValidateAntiForgeryToken]        public async Task<ActionResult> Login(SignInModel model, string returnUrl)        {            if (!ModelState.IsValid)            {                return View(model);            }            var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);            switch (result)            {                case SignInStatus.Success:                    return RedirectToLocal(returnUrl);                case SignInStatus.Failure:                default:                    ModelState.AddModelError("", "登陆无效");                    return View(model);            }        }        [AllowAnonymous]        public ActionResult Register()        {            return View();        }        [HttpPost]        [AllowAnonymous]        [ValidateAntiForgeryToken]        public async Task<ActionResult> Register(SignUpModel model)        {            if (ModelState.IsValid)            {                var user = new ApplicationUser { UserName = model.Email, Email = model.Email };                var result = await UserManager.CreateAsync(user, model.Password);                if (result.Succeeded)                {                    await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);                    return RedirectToAction("Index", "Home");                }                AddErrors(result);            }            return View(model);        }        [HttpPost]        [ValidateAntiForgeryToken]        public ActionResult LogOff()        {            AuthenticationManager.SignOut();            return RedirectToAction("Index", "Home");        }        private void AddErrors(IdentityResult result)        {            foreach (var error in result.Errors)            {                ModelState.AddModelError("", error);            }        }        private ActionResult RedirectToLocal(string returnUrl)        {            if (Url.IsLocalUrl(returnUrl))            {                return Redirect(returnUrl);            }            return RedirectToAction("Index", "Home");        }        private IAuthenticationManager AuthenticationManager        {            get { return HttpContext.GetOwinContext().Authentication; }        }

然后分别添加生成Login和Register页面

Login页面代码

@model IdentityDemo.Models.SignInModel@{    ViewBag.Title = "Login";}<h2>Login</h2>@using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post)){    @Html.AntiForgeryToken()        <div class="form-horizontal">        <h4>SignInModel</h4>        <hr />        @Html.ValidationSummary(true, "", new { @class = "text-danger" })        <div class="form-group">            @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.TextBoxFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })            </div>        </div>        <div class="form-group">            @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.PasswordFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })            </div>        </div>        <div class="form-group">            @Html.LabelFor(model => model.RememberMe, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                <div class="checkbox">                    @Html.CheckBoxFor(model => model.RememberMe)                    @Html.ValidationMessageFor(model => model.RememberMe, "", new { @class = "text-danger" })                </div>            </div>        </div>        <div class="form-group">            <div class="col-md-offset-2 col-md-10">                <input type="submit" value="SignIn" class="btn btn-default" />            </div>        </div>    </div>}<div>    @Html.ActionLink("注册", "Register")</div>

Register页面代码

@model IdentityDemo.Models.SignUpModel@{    ViewBag.Title = "Register";}<h2>Register</h2>@using (Html.BeginForm("Register", "Account", FormMethod.Post)){    @Html.AntiForgeryToken()        <div class="form-horizontal">        <h4>SignUpModel</h4>        <hr />        @Html.ValidationSummary(true, "", new { @class = "text-danger" })        <div class="form-group">            @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.TextBoxFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })                            </div>        </div>        <div class="form-group">            @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.PasswordFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })                            </div>        </div>        <div class="form-group">            @Html.LabelFor(model => model.ConfirmPassword, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.PasswordFor(model => model.ConfirmPassword, new { htmlAttributes = new { @class = "form-control" } })                            </div>        </div>        <div class="form-group">            <div class="col-md-offset-2 col-md-10">                <input type="submit" value="SignUp" class="btn btn-default" />            </div>        </div>    </div>}

然后往项目的根目录添加Startup类

然后修改根目录的Web.Config文件

最后我们来测试一下看看效果怎么样，如下图
