无法解析类型为“Microsoft”的服务。AspNetCore。身份UserManager`试图激活“AuthController”

Question

登录控制器中出现此错误。

无效操作异常：在尝试激活“汽车。服务器。控制器。AuthController”时，无法解析类型为“Microsoft. AspNetCore。身份。UserManager'1[汽车。模型。帐户]”的服务。

这是Auth Controller构造函数：

private SignInManager<Automobile.Models.Account> _signManager;
    private UserManager<Automobile.Models.Account> _userManager;

    public AuthController(UserManager<Models.Account> userManager,
                          SignInManager<Automobile.Models.Account> signManager)
    {
        this._userManager = userManager;
        this._signManager = signManager;
    }

这里是启动中的ConfigureServices。反恐精英：

public void ConfigureServices(IServiceCollection services)
    {
        // Add framework services.
        services.AddApplicationInsightsTelemetry(Configuration);
        services.Configure<AppConfig>(Configuration.GetSection("AppSettings"));

        //var provider = HttpContext.ApplicationServices;
        //var someService = provider.GetService(typeof(ISomeService));


        services.AddDbContext<Providers.Database.EFProvider.DataContext>(options => options
            .UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
                 b => b.MigrationsAssembly("Automobile.Server")
            ));


        services.AddIdentity<IdentityUser, IdentityRole>(options =>
        {
            options.User.RequireUniqueEmail = false;
        })
        .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
        .AddDefaultTokenProviders(); 
        //services.AddScoped<SignInManager<Automobile.Models.Account>, SignInManager<Automobile.Models.Account>>();
        //services.AddScoped<UserManager<Automobile.Models.Account>, UserManager<Automobile.Models.Account>>();

        services.AddMvc();
        App.Service = services.BuildServiceProvider();

        // Adds a default in-memory implementation of IDistributedCache.
        services.AddDistributedMemoryCache();

        services.AddSession(options =>
        {
            // Set a short timeout for easy testing.
            options.IdleTimeout = TimeSpan.FromSeconds(10);
            options.CookieHttpOnly = true;
        });

    }

这与原始帖子有点无关，但由于Google将您带到这里......如果您收到此错误并正在使用：

services.AddIdentityCore<YourAppUser>()

然后，您需要手动注册AddIdentity所做的工作，可以在此处找到：https://github.com/aspnet/Identity/blob/feedcb5c53444f716ef5121d3add56e11c7b71e5/src/Identity/IdentityServiceCollectionExtensions.cs#L79

        services.AddHttpContextAccessor();
        // Identity services
        services.TryAddScoped<IUserValidator<TUser>, UserValidator<TUser>>();
        services.TryAddScoped<IPasswordValidator<TUser>, PasswordValidator<TUser>>();
        services.TryAddScoped<IPasswordHasher<TUser>, PasswordHasher<TUser>>();
        services.TryAddScoped<ILookupNormalizer, UpperInvariantLookupNormalizer>();
        services.TryAddScoped<IRoleValidator<TRole>, RoleValidator<TRole>>();
        // No interface for the error describer so we can add errors without rev'ing the interface
        services.TryAddScoped<IdentityErrorDescriber>();
        services.TryAddScoped<ISecurityStampValidator, SecurityStampValidator<TUser>>();
        services.TryAddScoped<ITwoFactorSecurityStampValidator, TwoFactorSecurityStampValidator<TUser>>();
        services.TryAddScoped<IUserClaimsPrincipalFactory<TUser>, UserClaimsPrincipalFactory<TUser, TRole>>();
        services.TryAddScoped<UserManager<TUser>>();
        services.TryAddScoped<SignInManager<TUser>>();
        services.TryAddScoped<RoleManager<TRole>>();

您需要用这些工具的实现来替换TUser和TRole，或者使用默认的IdentityUser、IdentityRole

Answer 2

只是想弄清楚答案：

如果在启动时使用类ApplicationUser。cs：服务。额外性

然后，在注入控制器时，必须在控制器中使用相同的类：

public AccountController(UserManager<ApplicationUser> userManager)

如果使用其他类，例如：

public AccountController(UserManager<IdentityUser> userManager)

然后您将得到以下错误：

无效操作异常：无法解析类型为“Microsoft”的服务。AspNetCore。身份。UserManager'1[标识用户]'

因为您在启动时使用了Application ationUser，而不是IdtyUser，所以此类型未在注入系统中注册。

Answer 3

您需要在SignInManager、UserManager和services中使用相同的用户数据模型。额外性。如果您使用自己的自定义应用程序角色模型类，则相同的主体为真。

所以，改变

services.AddIdentity<IdentityUser, IdentityRole>(options =>
    {
        options.User.RequireUniqueEmail = false;
    })
    .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
    .AddDefaultTokenProviders();

到

services.AddIdentity<Automobile.Models.Account, IdentityRole>(options =>
    {
        options.User.RequireUniqueEmail = false;
    })
    .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
    .AddDefaultTokenProviders();
