如何實現ASP.NET的NoSQL身份提供程序5 MVC 6

Question

根本沒有文檔。

我知道我必須實現我自己的IUser，我自己的IUserSTore，並以某種方式在startup.cs中註冊它們。我刪除了對EntityFramework的所有引用，因爲我想使用NoSQL後端。

只要有文件記錄和公開，「公約」理念是非常好的。

任何提示？

我剛剛做了Identity 2.0的自定義實現，正如您所說，我沒有找到任何有用的文檔。幸運的是，我設法實現了我的目標。

假設您使用的是N層架構，將您的業務邏輯與業務邏輯與數據訪問層隔離，我會回答您的問題。並假設有一個正在使用的依賴注入容器，如Unity。

我會解釋您必須遵守使用Identity框架與定製數據訪問的步驟：

首先，你必須聲明你的域類，實施IUSER，如果你願意，添加自定義屬性，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; } 
} 

然後，在你的業務邏輯層，你應該有一個處理相關的用戶授權，登錄名，密碼恢復，以及其他所有任務的類。該類必須從UserManager繼承。其結果將是什麼如下：

// 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; 
     } 
} 

當從的UserManager繼承，它將提供一系列由身份所使用的方法，它會迫使你的類調用基構造函數傳遞一個信息庫，但沒有任何資料庫，存儲庫必須實現接口：IUserStore，IPasswordStore，具體取決於您的要求。

這是酷的事情發生時。在你的數據訪問層中，你必須有你自定義的存儲庫模式實現，連接到NoSQL數據庫（讓我們假設它是Mongo）。所以，你的ICustomUserMongoRepository應該是這個樣子：

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

和你蒙戈庫應該是這樣的

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 
     } 

     // ... 
} 

然後最後你的控制器會是這個樣子：

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它用於提供基於SOLID原則的高質量軟件。如果您仔細觀察並仔細考慮，您將注意到此接口必須具有所有UserManager的方法才能允許AuthController通過UserManager類的AuthorizationManager調用所有繼承的方法

對不起長的職位。很難用幾行來解釋整個過程。我希望它有幫助。如果您有任何疑問或問題，請評論此答案，我會盡快回復。
