c# - 使用 ASP.NET Identity 2.2.1 设置简单注入(inject)器

Question

因此，我一直在尝试设置 ASP.NET Identity 2.2.1，但一直遇到障碍。对于应该由框架自动生成的东西来说，配置起来确实很复杂。我想我快到了，但我在使用 Simple Injector 设置 IoC 时仍然遇到问题。

我一直在阅读有关这些问题的其他 StackOverflow 问题和博客。它们中的大多数看起来已经过时了，因为它们处理的是 ASP.NET Identity 1.0。从 2.0 到 2.2.1 甚至有足够多的变化我遇到了一些过时解决方案的问题。或者解决方案涉及其他 IoC 框架，我无法将它们转换为 Simple Injector。我使用过其他 IoC 框架，但我是 Simple Injector 的新手。

更新 - Ric .Net's first link in his comment很有帮助。我已经重新格式化我的工作以适应他的建议，我想我快到了。但我还有一个问题。我已经用下面的代码替换了之前的代码。

1) 我更新了 ApplicationDbContext:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext(string connectionstring)
        : base(connectionstring, throwIfV1Schema: false)
    {
    }
}

2) 我从 ApplicationUserManager 中删除了 Create() 方法，并将其移动到一个初始化我所有简单注入(inject)器代码的类中:

public static class SimpleInjectorInitializer
{
    public static Container Initialize(IAppBuilder app)
    {
        var container = GetInitializeContainer(app);

        container.Verify();

        DependencyResolver.SetResolver(
            new SimpleInjectorDependencyResolver(container));

        return container;
    }

    public static Container GetInitializeContainer(
              IAppBuilder app)
    {
        var container = new Container();

        container.RegisterSingle<IAppBuilder>(app);

        container.RegisterPerWebRequest<
               ApplicationUserManager>();

        container.RegisterPerWebRequest<ApplicationDbContext>(() 
          => new ApplicationDbContext(
           "Your constring goes here"));

        container.RegisterPerWebRequest<IUserStore<
          ApplicationUser>>(() => 
            new UserStore<ApplicationUser>(
              container.GetInstance<ApplicationDbContext>()));

        container.RegisterInitializer<ApplicationUserManager>(
            manager => InitializeUserManager(manager, app));

        container.RegisterMvcControllers(
                Assembly.GetExecutingAssembly());

        return container;
    }

    private static void InitializeUserManager(
        ApplicationUserManager manager, IAppBuilder app)
    {
        manager.UserValidator = 
         new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        //Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator()
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };

        var dataProtectionProvider = 
             app.GetDataProtectionProvider();

        if (dataProtectionProvider != null)
        {
            manager.UserTokenProvider = 
             new DataProtectorTokenProvider<ApplicationUser>(
              dataProtectionProvider.Create("ASP.NET Identity"));
        }
    }
}

3) 我更改了Startup.cs中的配置方法:

public void Configuration(IAppBuilder app)
{
    var container = SimpleInjectorInitializer.Initialize(app);
    ConfigureAuth(app, container);
}

4) 我更新了 Configure.Auth.cs 中的 ConfigureAuth:

public void ConfigureAuth(IAppBuilder app, Container container)
{
    // Configure the db context and user manager to use a single instance per request
    //app.CreatePerOwinContext(ApplicationDbContext.Create);
    app.CreatePerOwinContext(container.GetInstance<ApplicationUserManager>);
    // Rest of code here ...

5) 然后我从 AccountsController 中删除了默认构造函数和 UserManager 属性。

我现在遇到的问题是，自 ASP.NET Identity 2.0 以来，他们添加了参数 ISecureDataFormat<AuthenticationTicket> accessTokenFormat到 AccountsController 构造函数。

public AccountController(ApplicationUserManager userManager, 
    ISecureDataFormat<AuthenticationTicket> accessTokenFormat)

那么现在，如何为 ISecureDataFormat<AuthenticationTicket> 添加 DI在简单注入(inject)器中？

Answer 1

于是求助Ric .Net (我在上面作为问题的一部分发布)和 Lucas Teles answer in another question我终于得到了答案。 Lucas 建议将这些行添加到我的 Simple Injector 设置中:

container.Register<ISecureDataFormat<AuthenticationTicket>,
    SecureDataFormat<AuthenticationTicket>>(Lifestyle.Scoped);
container.Register<ITextEncoder, Base64UrlTextEncoder>(Lifestyle.Scoped);
container.Register<IDataSerializer<AuthenticationTicket>, TicketSerializer>(
    Lifestyle.Scoped);
container.Register<IDataProtector>(
    () => new Microsoft.Owin.Security.DataProtection.DpapiDataProtectionProvider()
        .Create("ASP.NET Identity"),
    Lifestyle.Scoped);

所以现在我的容器构建方法如下所示:

public static Container GetInitializeContainer(IAppBuilder app)
{
    var container = new Container();

    // IoC for ASP.NET Identity
    container.RegisterSingleton<IAppBuilder>(app);
    container.Register<ApplicationUserManager>(Lifestyle.Scoped);
    container.Register<ApplicationDbContext>(
        () => new ApplicationDbContext("Your constring goes here"),
        Lifestyle.Scoped);
    container.Register<IUserStore<ApplicationUser>>(
        () => new UserStore<ApplicationUser>(
            container.GetInstance<ApplicationDbContext>()),
        Lifestyle.Scoped);
    container.RegisterInitializer<ApplicationUserManager>(
        manager => InitializeUserManager(manager, app));
    // Setup for ISecureDataFormat
    container.Register<ISecureDataFormat<AuthenticationTicket>, 
        SecureDataFormat<AuthenticationTicket>>(Lifestyle.Scoped);
    container.Register<ITextEncoder, Base64UrlTextEncoder>(Lifestyle.Scoped);
    container.Register<IDataSerializer<AuthenticationTicket>, 
        TicketSerializer>(Lifestyle.Scoped);
    container.Register<IDataProtector>(
        () => new Microsoft.Owin.Security.DataProtection.DpapiDataProtectionProvider()
            .Create("ASP.NET Identity"),
        Lifestyle.Scoped);

    // Register all controllers
    container.RegisterMvcControllers(Assembly.GetExecutingAssembly());

    return container;
}
