如何为 ASP.NET 5 MVC 6 实施 NoSQL 身份提供程序

How to implement a NoSQL Identity provider for ASP.NET 5 MVC 6

根本没有文档。

我知道我必须实现我自己的 IUser、我自己的 IUserSTore 并以某种方式在 startup.cs 中注册它们。我删除了对 EntityFramework 的所有引用,因为我想使用 NoSQL 后端。

"convention" 哲学非常好,只要它被记录在案并且 public。

有什么提示吗?

我刚刚自定义实现了 Identity 2.0,正如您所说,我没有找到任何有用的文档。但幸运的是,我设法实现了我的目标。

我会假设您使用 N 层架构来回答您的问题,将您的视图与业务逻辑隔离开来,并将业务逻辑与数据访问层隔离开来。并假设还使用了依赖注入容器,例如 Unity。

我将解释使用具有自定义数据访问权限的身份框架必须遵循的步骤:

首先,您必须声明您的域 class,实施 IUser,如果需要,还可以向其添加自定义属性:

//This class is implementing IUser with Guid as type because
//I needed to use Guid as default Id.
public class CustomUser : IUser<Guid>
{
      public string CustomProperty { get; set; }
}

然后,在您的业务逻辑层中,您应该有一个 class 来处理与用户授权、登录、密码恢复等相关的所有任务。这个class 必须继承自UserManager。结果如下:

// Business layer class must inherit from UserManager with
// CustomUser and Guid as types
public AuthorizationManager : UserManager<CustomUser, Guid>, IAuthorizationManager
{
      private readonly ICustomUserMongoRepository repository;
      private readonly ICustomEmailService emailService;
      private readonly ICustomTokenProvider tokenProvider;

      // Parameters being injected by Unity.
      // container.RegisterType<ICustomUserMongoRepository, CustomUserMongoRepository>();
      // ..
      // ..
      public AuthorizationManager(
                   ICustomUserMongoRepository repository,
                   ICustomEmailService emailService,
                   ICustomTokenProvider tokenProvider
                   ) 
                                 // calling base constructor passing
                                 // a repository which implements
                                 // IUserStore, among others.
                                 : base(repository)
      {
            this.repository = repository;

            // this.EmailService is a property of UserManager and
            // it has to be set to send emails by your class
            this.EmailService = emailService;

            // this.UserTokenProvider is a property of UserManager and
            // it has to be set to generate tokens for user password
            // recovery and confirmation tokens
            this.UserTokenProvider = tokenProvider;
      }
}

当从 UserManager 继承时,它会提供 Identity 使用的一系列方法,它会强制你的 class 调用基础构造函数传递一个存储库,但不是任何存储库,存储库必须实现接口:IUserStore、IPasswordStore,具体取决于您的要求。

这是很酷的事情发生的时候。在您的数据访问层中,您必须将存储库模式的自定义实现连接到 NoSQL 数据库(假设它是 Mongo)。因此,您的 ICustomUserMongoRepository 应如下所示:

public interface ICustomUserMongoRepository : IUserPasswordStore<CustomUser, Guid>, IUserEmailStore<CustomUser, Guid>, IUserRoleStore<CustomUser, Guid>
{
}

你的 Mongo 存储库应该是这样的

public CustomUserMongoRepository : MongoRepository<CustomUser>, ICustomUserMongoRepository
{
      // Here you must have your custom implementation (using Mongo) of 
      // ICustomUserRepository which is requesting your class to 
      // implement IUserPasswordStore methods as well

      public Task CreateAsync(CustomUser user)
      {
            //Custom Mongo implementation
      }

      public Task DeleteAsync(CustomUser user)
      {
            //Custom Mongo implementation
      }

      public Task GetEmailAsync(CustomUser user)
      {
            //Custom Mongo implementation
      }

      public Task GetEmailConfirmedAsync(CustomUser user)
      {
            //Custom Mongo implementation
      }

      // ...
}

然后你的控制器看起来像这样:

public class AuthController : Controller
{

    private readonly IAuthorizationManager manager;        

      // Manager being injected by Unity.
      // container.RegisterType<IAuthorizationManager, AuthorizationManager>();
    public AuthController(IAuthorizationManager manager)
    {
          this.manager = manager;
    }

    // Receives a LogInViewModel with all data needed to allow users to log in
    [HttpPost]
    public async Task<ActionResult> LogIn(LogInViewModel viewModel)
    {
         // FindAsync it's a method inherited from UserManager, that's
         // using the Mongo repository passed to the base class 
         // in the AuthorizationManager constructor
         var user = this.manager.FindAsync(viewModel.Email, viewModel.Password);

         if(user != null){ // Log in user and create user session }
         else { // Wrong username or password }

    }
}

重要!

接口 IAuthorizationManager 用于根据 SOLID 原则交付高质量的软件。如果你仔细观察并深入思考,你会注意到这个接口必须具有所有 UserManager 的方法,以允许 AuthController 调用 AuthorizationManager 从 UserManager 继承的所有方法 class
