如何实现ASP.NET的NoSQL身份提供程序5 MVC 6

Question

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。

只要有文件记录和公开，“公约”理念是非常好的。

任何提示？

我刚刚做了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。幸运的是，我设法实现了我的目标。

假设您使用的是N层架构，将您的业务逻辑与业务逻辑与数据访问层隔离，我会回答您的问题。并假设有一个正在使用的依赖注入容器，如Unity。

我会解释您必须遵守使用Identity框架与定制数据访问的步骤：

首先，你必须声明你的域类，实施IUSER，如果你愿意，添加自定义属性，它：

//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，在你的业务逻辑层，你应该有一个处理相关的用户授权，登录名，密码恢复，以及其他所有任务的类。该类必须从UserManager继承。其结果将是什么如下：

// 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; 
     } 
} 

当从的UserManager继承，它将提供一系列由身份所使用的方法，它会迫使你的类调用基构造函数传递一个信息库，但没有任何资料库，存储库必须实现接口：IUserStore，IPasswordStore，具体取决于您的要求。

这是酷的事情发生时。在你的数据访问层中，你必须有你自定义的存储库模式实现，连接到NoSQL数据库（让我们假设它是Mongo）。所以，你的ICustomUserMongoRepository应该是这个样子：

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

和你蒙戈库应该是这样的

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 
     } 

     // ... 
} 

然后最后你的控制器会是这个样子：

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它用于提供基于SOLID原则的高质量软件。如果您仔细观察并仔细考虑，您将注意到此接口必须具有所有UserManager的方法才能允许AuthController通过UserManager类的AuthorizationManager调用所有继承的方法

对不起长的职位。很难用几行来解释整个过程。我希望它有帮助。如果您有任何疑问或问题，请评论此答案，我会尽快回复。
