将ASP.NET MVC5身份验证添加到现有项目-Java 学习之路

131

我在网上看到过很多类似的页面，但大多数都使用新项目而不是现有项目，或者没有必要的功能 . 所以，我有一个现有的 MVC 5 项目，并希望集成 ASP.NET MVC5 Identity with log in, email confirmation and password reset 功能 .

除此之外，我还需要在数据库上创建所有 necessary tables ，即用户，角色，组等（我在我的项目中使用EF Code First） . 是否有符合这些需求的文章或样本？任何建议将不胜感激 . 提前致谢...

为现有项目配置标识并不困难 . 您必须安装一些NuGet包并进行一些小配置 .

首先在Package Manager Console中安装这些NuGet包：

PM> Install-Package Microsoft.AspNet.Identity.Owin 
PM> Install-Package Microsoft.AspNet.Identity.EntityFramework
PM> Install-Package Microsoft.Owin.Host.SystemWeb

添加用户类并使用 IdentityUser 继承：

public class AppUser : IdentityUser
{
    //add your custom properties which have not included in IdentityUser before
    public string MyExtraProperty { get; set; }  
}

为角色做同样的事情：

public class AppRole : IdentityRole
{
    public AppRole() : base() { }
    public AppRole(string name) : base(name) { }
    // extra properties here 
}

将您的 DbContext 父表单 DbContext 更改为 IdentityDbContext<AppUser> ，如下所示：

public class MyDbContext : IdentityDbContext<AppUser>
{
    // Other part of codes still same 
    // You don't need to add AppUser and AppRole 
    // since automatically added by inheriting form IdentityDbContext<AppUser>
}

如果使用相同的连接字符串并启用了迁移，EF将为您创建必要的表 .

（可选）您可以扩展 UserManager 以添加所需的配置和自定义：

public class AppUserManager : UserManager<AppUser>
{
    public AppUserManager(IUserStore<AppUser> store)
        : base(store)
    {
    }

    // this method is called by Owin therefore best place to configure your User Manager
    public static AppUserManager Create(
        IdentityFactoryOptions<AppUserManager> options, IOwinContext context)
    {
        var manager = new AppUserManager(
            new UserStore<AppUser>(context.Get<MyDbContext>()));

        // optionally configure your manager
        // ...

        return manager;
    }
}

由于Identity基于OWIN，因此您还需要配置OWIN：

将类添加到 App_Start 文件夹（如果需要，可以添加到其他任何位置） . 该类由OWIN使用

namespace MyAppNamespace
{
    public class IdentityConfig
    {
        public void Configuration(IAppBuilder app)
        {
            app.CreatePerOwinContext(() => new MyDbContext());
            app.CreatePerOwinContext<AppUserManager>(AppUserManager.Create);
            app.CreatePerOwinContext<RoleManager<AppRole>>((options, context) =>
                new RoleManager<AppRole>(
                    new RoleStore<AppRole>(context.Get<MyDbContext>())));

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Home/Login"),
            });
        }
    }
}

几乎只需将这行代码添加到 web.config 文件中，以便OWIN可以找到您的启动类 .

<appSettings>
    <!-- other setting here -->
    <add key="owin:AppStartup" value="MyAppNamespace.IdentityConfig" />
</appSettings>

现在在整个项目中，您可以使用Identity，就像VS已经安装了新项目一样 . 例如，考虑登录操作

[HttpPost]
public ActionResult Login(LoginViewModel login)
{
    if (ModelState.IsValid)
    {
        var userManager = HttpContext.GetOwinContext().GetUserManager<AppUserManager>();
        var authManager = HttpContext.GetOwinContext().Authentication;

        AppUser user = userManager.Find(login.UserName, login.Password);
        if (user != null)
        {
            var ident = userManager.CreateIdentity(user, 
                DefaultAuthenticationTypes.ApplicationCookie);
            //use the instance that has been created. 
            authManager.SignIn(
                new AuthenticationProperties { IsPersistent = false }, ident);
            return Redirect(login.ReturnUrl ?? Url.Action("Index", "Home"));
        }
    }
    ModelState.AddModelError("", "Invalid username or password");
    return View(login);
}

您可以创建角色并添加到您的用户：

public ActionResult CreateRole(string roleName)
{
    var roleManager=HttpContext.GetOwinContext().GetUserManager<RoleManager<AppRole>>();

    if (!roleManager.RoleExists(roleName))
        roleManager.Create(new AppRole(roleName));
    // rest of code
}

您可以向任何用户添加任何角色，如下所示：

UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");

通过使用 Authorize ，您可以保护您的操作或控制器：

[Authorize]
public ActionResult MySecretAction() {}

要么

[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}

您还可以安装其他软件包并配置它们以满足您的要求，例如 Microsoft.Owin.Security.Facebook 或您想要的任何一个 .

Note: 不要忘记在文件中添加相关的命名空间：

using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;

您还可以看到我的其他答案，如this和this，以便高级使用Identity .

这就是我将Identity与现有数据库集成的方法 .

使用MVC模板创建示例MVC项目 . 这包含Identity实现所需的所有代码 - Startup.Auth.cs，IdentityConfig.cs，Account Controller代码，Manage Controller，Models和相关视图 .
为Identity和OWIN安装必要的nuget包 . 通过查看示例项目中的引用和@Sam的答案，您将获得一个想法
将所有这些代码复制到现有项目中 . 请注意，不要忘记为Identity添加“DefaultConnection”连接字符串以映射到您的数据库 . 请检查IdentityModel.cs中的ApplicationDBContext类，您将在其中找到对“DefaultConnection”连接字符串的引用 .
这是我在现有数据库上运行的SQL脚本，用于创建必要的表：

检查并解决任何剩余的错误，您就完成了 . 身份将处理其余的:)

我推荐IdentityServer . 这是一个.NET Foundation项目，涉及许多有关身份验证和授权的问题 .

概述

IdentityServer是一个基于.NET / Katana的框架和托管组件，允许使用OpenID Connect和OAuth2等协议为现代Web应用程序和API实现单点登录和访问控制 . 它支持广泛的客户端，如移动，Web，SPA和桌面应用程序，并且可扩展以允许集成到新的和现有的体系结构中 .

有关详细信息，例如
- 支持MembershipReboot和基于ASP.NET身份的用户存储
- 支持额外的Katana身份验证中间件（例如Google，Twitter，Facebook等）
- 支持基于EntityFramework的持久性配置
- 支持WS-Federation
- 可扩展性
看看documentation和samples .
