c# - Asp.Net Core 2.1 Identity - UserStore 依赖注入

问题描述

我正在尝试UserStore为我的身份模型实现自定义；但是，我在应用程序启动时收到此运行时错误：

InvalidOperationException：尝试激活“[Project].Models.Identity.ApplicationUserManager”时，无法解析“[Project].Models.Identity.ApplicationUserStore”类型的服务。

我的UserStore实现：

public class ApplicationUserStore : IUserStore<Employee>,
                     IUserClaimStore<Employee>,
                     IUserLoginStore<Employee>,
                     IUserRoleStore<Employee>,
                     IUserPasswordStore<Employee>,
                     IUserSecurityStampStore<Employee>
{
    #region Constructor signatures I tried for dependency injection
    public ApplicationUserStore(ApplicationDbContext context, IdentityErrorDescriber describer = null)
    {

    }
    public ApplicationUserStore(ApplicationDbContext context)
    {

    }
    public ApplicationUserStore()
    {

    }
    public ApplicationUserStore(DbContext context)
    {

    }
    #endregion
    ...

我的UserManager实现：

public class ApplicationUserManager : UserManager<Employee>
{
    public ApplicationUserManager(ApplicationUserStore store, IOptions<IdentityOptions> optionsAccessor, IPasswordHasher<Employee> passwordHasher, IEnumerable<IUserValidator<Employee>> userValidators, IEnumerable<IPasswordValidator<Employee>> passwordValidators, ILookupNormalizer keyNormalizer, IdentityErrorDescriber errors, IServiceProvider services, ILogger<UserManager<Employee>> logger)
        : base(store, optionsAccessor, passwordHasher, userValidators, passwordValidators, keyNormalizer, errors, services, logger)
    {
    }
}

我的SignInManager实现：

public class ApplicationSignInManager : SignInManager<Employee>
{
    public ApplicationSignInManager(ApplicationUserManager userManager, IHttpContextAccessor contextAccessor, IUserClaimsPrincipalFactory<Employee> claimsFactory, IOptions<IdentityOptions> optionsAccessor, ILogger<SignInManager<Employee>> logger, IAuthenticationSchemeProvider schemes)
        : base(userManager, contextAccessor, claimsFactory, optionsAccessor, logger, schemes)
    {
    }
}

并且，在Startup.ConfigureServices：

        ...
        services.AddIdentityCore<Employee>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddUserStore<ApplicationUserStore>()
            .AddUserManager<ApplicationUserManager>()
            .AddSignInManager<ApplicationSignInManager>()
            .AddDefaultTokenProviders();

        services.AddTransient<IUserStore<Employee>, ApplicationUserStore>();
        ...

我需要知道是什么导致了问题，如何解决它，以及是否在任何地方都有关于 Asp.Net Core 2.1 依赖注入激活器签名的文档。

解决方案

在查看了此处和此处的开源实现之后，我想出了可能是什么问题的线索——我猜对了。UserStore需要通过以下行注册Startup.ConfigureServices：

    services.AddScoped<ApplicationUserStore>();

所以，我的最终方法是：

    ...
    services.AddIdentityCore<Employee>()
        .AddUserManager<ApplicationUserManager>()
        .AddSignInManager<ApplicationSignInManager>()
        .AddDefaultTokenProviders();

    services.AddScoped<IUserStore<Employee>, ApplicationUserStore>();
    services.AddScoped<ApplicationUserStore>();
    ...

尽管如此，它在没有：

    services.AddScoped<IUserStore<Employee>, ApplicationUserStore>();
