asp.net - Asp.Net Core 3 Web API 身份

Question

我已经存货 3 天了，没有可能的在线解决方案出现此错误

System.AggregateException
  HResult=0x80131500
  Message=Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Microsoft.AspNetCore.Identity.ISecurityStampValidator Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.SecurityStampValidator`1[MyTrBox_WebAPI.Model.User]': Unable to resolve service for type 'Microsoft.AspNetCore.Authentication.ISystemClock' while attempting to activate 'Microsoft.AspNetCore.Identity.SecurityStampValidator`1[MyTrBox_WebAPI.Model.User]'.)

Inner Exception 2:
InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Authentication.ISystemClock' while attempting to activate 'Microsoft.AspNetCore.Identity.SecurityStampValidator`1[MyTrBox_WebAPI.Model.User]'.

这是我在启动时用来添加身份的代码

 var builder = services.AddIdentityCore<User>();
            builder = new IdentityBuilder(
                builder.UserType,
                typeof(UserRole),
                builder.Services);

            builder.AddRoles<UserRole>()
                .AddEntityFrameworkStores<AppDbContext>()
                .AddDefaultTokenProviders()
                .AddSignInManager<SignInManager<User>>();

用户等级：

public class User : IdentityUser<Guid>
    {
        public string Country { get; set; }
        public DateTimeOffset CreatedAt { get; set; }
    }

用户角色类：

public class UserRole : IdentityRole<Guid>
    {
        public UserRole()
            : base() {

        } 
        public UserRole(string roleName)
            : base(roleName) {

        }
    }

当我对 API 服务器进行任何调用时，我总是遇到上述错误提前谢谢

编辑：

.csproj：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <RootNamespace>MyTrBox_WebAPI</RootNamespace>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoMapper" Version="9.0.0" />
    <PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="7.0.0" />

对于自定义 asp.net 核心身份，您可以按照以下步骤操作：

1. .csproj

   <Project Sdk="Microsoft.NET.Sdk.Web">
   
   <PropertyGroup>
       <TargetFramework>netcoreapp3.0</TargetFramework>
   </PropertyGroup>
   
   <ItemGroup>
       <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0" />
       <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.0.0" />
       <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0" />
       <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.0.0">
       <PrivateAssets>all</PrivateAssets>
       <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
       </PackageReference>
       <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="3.0.0" />
       <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.0.0" />
   </ItemGroup>
   
   </Project>
   

2. CoreSecurityContext

   public class CoreSecurityContext : IdentityDbContext<User, UserRole, Guid>
   {
       public CoreSecurityContext(DbContextOptions<CoreSecurityContext> options)
           : base(options)
       {
       }
   
       protected override void OnModelCreating(ModelBuilder builder)
       {
           base.OnModelCreating(builder);
           // Customize the ASP.NET Identity model and override the defaults if needed.
           // For example, you can rename the ASP.NET Identity table names and more.
           // Add your customizations after calling base.OnModelCreating(builder);
       }
   }
   

3. Startup.cs

   services.AddDefaultIdentity<User>()
           .AddRoles<UserRole>()
           .AddEntityFrameworkStores<CoreSecurityContext>();
