【问题描述】：

我在登录控制器中收到此错误。

System.InvalidOperationException：尝试激活“UsersAuth.Controllers.AuthenticateController”时，无法解析“Microsoft.AspNetCore.Identity.UserManager`1[UsersAuth.IdentityAuth.UserApplication]”类型的服务。

这里是 Authenticate Controller 构造函数：

public class AuthenticateController : ControllerBase
    
        private readonly UserManager<UserApplication> _userManager;
        private readonly RoleManager<IdentityRole> _roleManager;
        private readonly IConfiguration _configuration;

        public AuthenticateController(UserManager<UserApplication> userManager, RoleManager<IdentityRole> roleManager, IConfiguration configuration)
        
            _userManager = userManager;
            _roleManager = roleManager;
            _configuration = configuration;
        

这里是 startup.cs 中的 ConfigureServices：

public void ConfigureServices(IServiceCollection services)

    services.AddControllers();

    services.AddDbContext<ApplicationDbContext>(options=>options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

    services.AddAuthentication(options =>
    
        options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
     )
     .AddJwtBearer(options =>
     
         options.SaveToken = true;
         options.RequireHttpsMetadata = false;
         options.TokenValidationParameters = new TokenValidationParameters()
         
             ValidateIssuer = true,
             ValidateAudience = true,
             ValidIssuer = Configuration["JWT:ValidIssuer"],
             ValidAudience = Configuration["JWT:ValidAudience"],
             IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["JWT:SecretKey"]))
         ;
     );

【参考方案1】：

您没有为 UserApplication 配置依赖注入。有不同的方法可以做到这一点，例如

services.AddDefaultIdentity<UserApplication>(options =>
   options.SignIn.RequireConfirmedAccount = true)
   .AddEntityFrameworkStores<ApplicationDbContext>();

或者，如果您想要更精细的控制，

services.AddIdentityCore<AppUser>(opt => 
    opt.Password.RequiredLength = 8;
    ...
)
.AddSignInManager()
.AddRoles<IdentityRole>();
