我在登录控制器中收到此错误。
InvalidOperationException:尝试激活'Automobile.Server.Controllers.AuthController'时,无法解析类型'Microsoft.AspNetCore.Identity.UserManager`1 [Automobile.Models.Account]'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;
}
这是startup.cs中的ConfigureServices:
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;
});
}

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,则同样的原则。
所以,改变
browser.PrintToPdfAsync(@"C:\out.pdf", new PdfPrintSettings
{
BackgroundsEnabled = true,
HeaderFooterEnabled = false,
Landscape = false,
MarginType = CefPdfPrintMarginType.Custom,
MarginBottom = 0,
MarginTop = 0,
MarginLeft = 0,
MarginRight = 0,
PageWidth = 210000,
PageHeight = 297000
});
到
services.AddIdentity<IdentityUser, IdentityRole>(options =>
{
options.User.RequireUniqueEmail = false;
})
.AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
.AddDefaultTokenProviders();

要明确答案:
如果您在startup.cs中使用课程ApplicationUser
:services.AddIdentity<ApplicationUser, IdentityRole>()
然后在注入时必须在控制器中使用相同的类:
public AccountController(UserManager<ApplicationUser> userManager)
如果您使用其他类,例如:
public AccountController(UserManager<IdentityUser> userManager)
然后你会收到这个错误:
InvalidOperationException:无法解析类型'Microsoft.AspNetCore.Identity.UserManager`1 [IdentityUser]'
的服务
因为你在启动时使用ApplicationUser
而不是IdentityUser
所以这种类型没有在注射系统中注册。

您可以在Startup类内部的ConfigureServices中分别设置IdentityUser和IdentityRole,如下所示:
services.AddDefaultIdentity<IdentityUser>()
.AddRoles<IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>();
OR
您可以直接在AddIdentity中进行配置:
services.AddIdentity<IdentityUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>();

这与原始帖子有点无关,但是由于Google将您带到这里...如果您遇到此错误并正在使用:
services.AddIdentityCore<YourAppUser>()
然后,您将需要手动注册AddIdentity
所做的工作,可以在这里找到:
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>>();
您需要将TUser
和TRole
替换为您的实现,或默认的IdentityUser
,IdentityRole
答案 4 :(得分:1)
不要忘记在ConfigureServices中添加角色管理器
services.AddDefaultIdentity<IdentityUser>()
.AddRoles<IdentityRole>() // <--------
.AddDefaultUI(UIFramework.Bootstrap4)
.AddEntityFrameworkStores<ApplicationDbContext>();

如果您使用的是“ IdentityServer”,则IdentityServer会对用户进行身份验证并授权客户端。默认情况下,IdentityServer实际上与用户管理无关。但是对asp.net Identity
有一些支持因此您需要添加:
services.AddIdentityServer()
.AddAspNetIdentity<ApplicationUser>();
答案 6 :(得分:0)
您需要使用以下内容更新Statup.cs类
services.AddIdentity
这里:ApplicationUser是我的自定义模型类。
