我在 mac 機器上使用 asp.net 核心，我試圖為我的 asp.net mvc web 應用程序創建一個自定義的 ApplicationUser，它與基本 IdentityUser 一起工作得非常好。盡管遵循 Microsoft 的本指南：https://docs.microsoft.com/en-us/aspnet/core/security/authentication/add-user-data?view=aspnetcore-2.1&tabs=visual-studio我面臨這個錯誤：{"error":"沒有注冊'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]'類型的服務。"}以下是我的代碼片段：啟動文件 public void ConfigureServices(IServiceCollection services) { services.Configure<CookiePolicyOptions>(options => { // [...] services.AddDbContext<ApplicationDbContext>( options => options.UseSqlServer(identityDbContextConnection)); // Relevant part: influences the error services.AddIdentity<ApplicationUser, IdentityRole>() .AddEntityFrameworkStores<ApplicationDbContext>() .AddDefaultTokenProviders(); services.AddMvc(config => { var policy = new AuthorizationPolicyBuilder() .RequireAuthenticatedUser() .Build(); config.Filters.Add(new AuthorizeFilter(policy)); }); }應用程序用戶.cs // Add profile data for application users by adding properties to the ApplicationUser classpublic class ApplicationUser : IdentityUser{ [Required] public string DrivingLicense { get; set; }}注冊.cshtml.cspublic class RegisterModel : PageModel{ private readonly SignInManager<ApplicationUser> _signInManager; private readonly UserManager<ApplicationUser> _userManager; private readonly ILogger<RegisterModel> _logger; private readonly IServiceProvider _services; public RegisterModel( UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager, ILogger<RegisterModel> logger, IServiceProvider services ) { _userManager = userManager; _signInManager = signInManager; _logger = logger; _services = services; }

問題出在“_LoginPartial.cshtml”中
刪除這個
@using Microsoft.AspNetCore.Identity
@inject SignInManager<IdentityUser> SignInManager
@inject UserManager<IdentityUser> UserManager
添加這個
@using Microsoft.AspNetCore.Identity
@inject SignInManager<ApplicationUser> SignInManager
@inject UserManager<ApplicationUser> UserManager

在 dotnet core 2.1 中，我遇到了同樣的問題，以下步驟解決了我的問題
1 ) 擴展 IdentityUser 或 IdentityRole
public class ApplicationUser : IdentityUser<Guid>
{
public DateTime JoinTime { get; set; } = DateTime.Now;
public DateTime DOB { get; set; } = Convert.ToDateTime("01-Jan-1900");
}
public class ApplicationRole : IdentityRole<Guid>
{
public string Description { get; set; }
}
2）更新ApplicationDbContext類
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, Guid>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
{
}
}
3) 更新 Stratup.cs 配置服務
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>, AppClaimsPrincipalFactory>();
services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, ApplicationRole>().AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultUI()
.AddDefaultTokenProviders();
}
更新 _LoginPartial.cshtml（共享 --> 查看）
@inject SignInManager<ApplicationUser> SignInManager
@inject UserManager<ApplicationUser> UserManager

核心2有同樣的問題。
你需要檢查一個更大的面積是在文件_ManageNav.cshtml有你有更新的訂單@inject SignInManager<IdentityUser> SignInManager有@inject SignInManager<YOURCUSTOMMODEL> SignInManager。
希望有幫助
