Question

根本没有文件。

我知道我必须实现自己的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。

＆＃34;惯例＆＃34;只要记录和公开，哲学就是非常好的。

任何提示？

我刚刚完成了Identity 2.0的自定义实现，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。

我会回答您的问题，假设您使用的是N层架构，将您的业务逻辑和业务逻辑与数据访问层隔离开来。并假设还有一个依赖注入容器，如Unity。

我将解释在使用Identity框架和自定义数据访问时必须遵循的步骤：

首先，您必须声明您的域类，实现IUser，并且如果需要，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，在业务逻辑层中，您应该有一个类来处理与用户授权，登录，密码恢复等相关的所有任务。此类必须从UserManager继承。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;
      }
}

当继承自UserManager时，它将提供Identity使用的一系列方法，它将强制您的类调用基础构造函数来传递存储库，但不是任何存储库，存储库必须实现接口：IUserStore， IPasswordStore，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（让我们假设它是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用于提供基于SOLID原则的高质量软件。如果你仔细观察并深入思考它，你会注意到这个接口必须有所有UserManager的方法，允许AuthController通过UserManager类的AuthorizationManager调用所有继承的方法

对不起，很长的帖子。很难用几行来解释整个过程。我希望它有所帮助。如果您有任何疑问或疑问，请回答此问题，我会尽快回复。
