使用AddSignInManager时的ASP.NET Core MVC异常

我正在使用ASP.NET Core MVC 3.0 API项目。我正在使用Microsoft.AspNetCore.Identityv3.0

在Startup.cs，里面的ConfigureServices方法，当我输入下面并运行应用程序，我得到一个异常：

var builder = services.AddIdentityCore<AppUser>();
var identityBuilder = new IdentityBuilder(builder.UserType, builder.Services);
identityBuilder.AddEntityFrameworkStores<DataContext>();
identityBuilder.AddSignInManager<SignInManager<AppUser>>();

该AppUser班是这样的：

using Microsoft.AspNetCore.Identity;

namespace Domain
{
    public class AppUser : IdentityUser
    {
        public string DisplayName { get; set; }
    }
}

我得到的例外是：

未处理的异常。System.AggregateException：某些服务无法构造（验证服务描述符“ ServiceType：Microsoft.AspNetCore.Identity.ISecurityStampValidator的生命周期：范围实现类型：Microsoft.AspNetCore.Identity.SecurityStampValidator`1 [Domain.AppUser]”：尝试激活“ Microsoft.AspNetCore.Identity.SecurityStampValidator`1 [Domain.AppUser]”时，无法解析类型为“ Microsoft.AspNetCore.Authentication.ISystemClock”的服务。）（验证服务描述符“ ServiceType：Microsoft.AspNetCore”时出错.Identity.ITwoFactorSecurityStampValidator寿命：作用域实现类型：Microsoft.AspNetCore.Identity.TwoFactorSecurityStampValidator`1 [Domain.AppUser]'：无法为类型'Microsoft.AspNetCore.Authentication解析服务。

知道我在做什么错吗？

最好使用AddDefaultIdentity来帮助您注册SignInManager。您可以参考以下步骤：

编辑项目文件以安装软件包：

<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>
    </ItemGroup>

</Project>

创建DataContext：

public class DataContext : IdentityDbContext<AppUser>
{
    public DataContext(DbContextOptions<DataContext> 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);
    }
}

Startup.cs：

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

services.AddDefaultIdentity<AppUser>()
.AddEntityFrameworkStores<DataContext>();

注入SignInManager：

private readonly UserManager<AppUser> _userManager;
private readonly SignInManager<AppUser> _signInManager;
private readonly DataContext _context; 

public WeatherForecastController(UserManager<AppUser> userManager,SignInManager<AppUser> signInManager, DataContext dbContext)
{
    _userManager = userManager;
    _signInManager = signInManager;
    _context = dbContext;

}

并使用像：

await _signInManager.SignInAsync(user, isPersistent: false);
