尝试激活“AuthController"时无法解析“Microsoft.AspNetCore.Identity.UserManager"类型的服务 [英] Unable to resolve service for type 'Microsoft.AspNetCore.Identity.UserManager` while attempting to activate 'AuthController'

问题描述

我在登录控制器中收到此错误.

I'm getting this error in Login Controller.

InvalidOperationException:在尝试激活Automobile.Server.Controllers.AuthController"时无法解析Microsoft.AspNetCore.Identity.UserManager`1[Automobile.Models.Account]"类型的服务.

InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Automobile.Models.Account]' while attempting to activate 'Automobile.Server.Controllers.AuthController'.

这里是身份验证控制器构造函数:

here is Auth Controller constructor:

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 startup.cs 中的 ConfigureServices:

and here is ConfigureServices in startup.cs:

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;
        });

    }

推荐答案

您需要在 SignInManager、UserManager 和 services.AddIdentity 中使用相同的用户数据模型.如果您使用自己的自定义应用程序角色模型类，同样的原则也是如此.

You need to use the same user data model in SignInManager, UserManager and services.AddIdentity. Same principal is true if you are using your own custom application role model class.

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();
