项目,并希望将 ASP.NET MVC5身份与登录,电子邮件确认和密码重置功能集成。
除此之外,我还需要在数据库上创建所有必要的表,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。提前谢谢......

为现有项目配置身份并不困难。您必须安装一些NuGet包并进行一些小配置。
首先使用软件包管理器控制台安装这些NuGet软件包:
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
家长从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>
}
如果您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格。
或者,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 this is the 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,您还需要配置OWIN:
将一个类添加到App_Start
文件夹(或任何其他地方,如果需要)。该类由OWIN使用。这将是你的初创班。
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"),
});
}
}
}
几乎只需将此行代码添加到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已经安装的任何新项目一样。考虑登录操作,例如
[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
}
您还可以向用户添加角色,如下所示:
UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");
使用Authorize
你可以保护你的行动或控制者:
[Authorize]
public ActionResult MySecretAction() {}
或
[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}
您还可以安装其他软件包并对其进行配置,以满足Microsoft.Owin.Security.Facebook
或您想要的任何要求。
注意: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;

这是我将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
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错误,您就完成了。身份将处理其余部分:)

我建议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。
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。

好吧,我知道我可能为时已晚。
这适用于那些已经做过一次或多次迁移的人。那些项目完美运行的人,那些在数据库中有 AspNet 表,但没有与这些相关的控制器、模型和视图的人。
我也遇到了同样的问题。我在开始时没有激活身份验证就开始了我的项目。然后我意识到我没有用于身份验证的所有元素(Views 文件夹中的 Account 和 Manage,控制器中的 accountController 和 ManageControler,以及模型中的 AccountViewModel 和 ManageViewModel)。
我刚刚创建了其他具有类似设置、名称的项目,并在创建该项目时激活了身份验证。
然后我设法将丢失的文件复制到我的初始项目中。
之后,我经历了每一次更改命名空间并导入到我的项目的命名空间
