将自定义 UserManager 注入 Controller Net Core 2.1

Question

我在尝试将我的 UserManager 注入我的控制器时遇到问题。

这是我的自定义用户管理器：

  public class ApplicationUserManager : UserManager<ApplicationUser>
    {

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

            }


        public async Task<ApplicationUser> FindAsync(string id, string password)
        {
            ApplicationUser user = await FindByIdAsync(id);
            if (user == null)
            {
                return null;
            }
            return await CheckPasswordAsync(user, password) ? user : null;
        }
    }

这是我的Startup.cs

public IServiceProvider ConfigureServices(IServiceCollection services)
        {
            services.ConfigureCors();
            services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(options =>
                {
                    options.TokenValidationParameters = new TokenValidationParameters
                    {
                        ValidateIssuer = true,
                        ValidateAudience = true,
                        ValidateLifetime = true,
                        ValidateIssuerSigningKey = true,
                        ValidIssuer = Configuration["Jwt:Issuer"],
                        ValidAudience = Configuration["Jwt:Issuer"],
                        IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"]))
                    };
                });
            // Add framework services.
            services.AddMvc();
            services.AddScoped<ApplicationUserManager>();

            var builder = new ContainerBuilder();
            builder.Populate(services);

            // Registering MongoContext. 
            builder.RegisterType<MongoContext>().AsImplementedInterfaces<MongoContext, ConcreteReflectionActivatorData>().SingleInstance();
            //builder.RegisterType<MongoContext>().As<IMongoContext>();

            //Registering ApplicationUserManager. 

   builder.RegisterType<ApplicationUserManager>().As<UserManager<ApplicationUser>>().SingleInstance();
        //builder.RegisterType<ApplicationUserManager>().As<ApplicationUserManager>().SingleInstance();

重要的两行是：
builder.RegisterType ApplicationUserManager ().As UserManager ApplicationUser ().SingleInstance();
builder.RegisterType ApplicationUserManager ().As ApplicationUserManager ().SingleInstance;

我的控制器：（我用这两个构造函数测试了它，得到了同样的错误）

 public AccountController(ApplicationUserManager applicationUserManager)
        {
            this.applicationUserManager = applicationUserManager;
        }
        public AccountController(UserManager<ApplicationUser> userManager)
        {
            this.userManager = userManager;
        }

最后是错误：

Autofac.Core.DependencyResolutionException: None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'VotNetMon.ApplicationUserManager' can be invoked with the available services and parameters: Cannot resolve parameter 'Microsoft.AspNetCore.Identity.IUserStore1[VotNetMon.Entities.ApplicationUser] store' of constructor 'Void .ctor(Microsoft.AspNetCore.Identity.IUserStore1[VotNetMon.Entities.ApplicationUser], Microsoft.Extensions.Options.IOptions1[Microsoft.AspNetCore.Identity.IdentityOptions], Microsoft.AspNetCore.Identity.IPasswordHasher1[VotNetMon.Entities.ApplicationUser], System.Collections.Generic.IEnumerable1[Microsoft.AspNetCore.Identity.IUserValidator1[VotNetMon.Entities.ApplicationUser]], System.Collections.Generic.IEnumerable1[Microsoft.AspNetCore.Identity.IPasswordValidator1[VotNetMon.Entities.ApplicationUser]], Microsoft.AspNetCore.Identity.ILookupNormalizer, Microsoft.AspNetCore.Identity.IdentityErrorDescriber, System.IServiceProvider, Microsoft.Extensions.Logging.ILogger1[Microsoft.AspNetCore.Identity.UserManager1[VotNetMon.Entities.ApplicationUser]])'. at Autofac.Core.Activators.Reflection.ReflectionActivator.GetValidConstructorBindings(IComponentContext context, IEnumerable1 parameters) at Autofac.Core.Activators.Reflection.ReflectionActivator.ActivateInstance(IComponentContext context, IEnumerable1 parameters) at Autofac.Core.Resolving.InstanceLookup.Activate(IEnumerable`1 parameters)

正如错误所说，您必须注册 IUserStore 和通常由 AspNetIdentity 的扩展方法注册的其他依赖项。

services.AddIdentity<ApplicationUser, IdentityRole>();

请注意，这还会添加 cookie 身份验证，因为这是 asp.net identity does. If you persist on doing it with autofac, what is totally legit, you should look here 必须注册的类。

如果您想一起使用 identity 和 jwt，here 是一个很好的教程，可以指导您完成它。

不直接相关：

请始终使用接口，不要注入实现，因此不要配置容器来解析实现。
有一种新方法可以结合使用 autofac 和微软的 ioc，这是首选。你可以找到一个例子 here。这是 asp.net core >= 2.0.
