将身份验证从 dotnet core 1.1 迁移到 dotnet core 2.0

Question

我们刚刚将身份验证中间件从 .net core 1.1 迁移到 .net core 2.0，遵循答案中的示例。但是，当我尝试发出请求时（即使尝试访问 Swagger UI），一切都会构建并运行，我在名为 UserAuthHandler 的自定义 AuthenticationHandler 上收到以下异常： System.InvalidOperationException: A suitable constructor for type 'BrokerAPI.AuthMiddleware.UserAuthHandler' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.
来自 UserAuthHandler 的代码：

public class UserAuthHandler : AuthenticationHandler<UserAuthAuthenticationOptions>    
{
    protected UserAuthHandler(IOptionsMonitor<UserAuthAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock) : base(options, logger, encoder, clock)
    {
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync()
    {
        //handle authentication
        var ticket = new AuthenticationTicket(new ClaimsPrincipal(identity),
           new AuthenticationProperties(), "UserAuth");

        return Task.FromResult(AuthenticateResult.Success(ticket));
    }
}

来自 UserAuthExtensions 的代码：

public static class UserAuthExtensions
{
    public static AuthenticationBuilder AddCustomAuth(this AuthenticationBuilder builder, Action<UserAuthAuthenticationOptions> configureOptions)
    { 
        return builder.AddScheme<UserAuthAuthenticationOptions, UserAuthHandler>("UserAuth", "UserAuth", configureOptions);
    }
}

我如何调用 Startup.cs 中的所有内容：

public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(options =>
            {
                options.DefaultScheme = "UserAuth";
            }).AddCustomAuth(o => { });
    }
public void Configure()
    {
        app.UseAuthentication();
    }

我搜索了 Google 示例和有类似问题的人，但无济于事。

我是否遗漏了与我的 DI 容器相关的内容？或者它通常与 .net core 2 中的身份验证有关？

提前致谢。

异常消息实际上非常清楚：您的处理程序有一个受保护的构造函数，不能被依赖注入系统使用。使其成为 public，它应该可以工作：

public class UserAuthHandler : AuthenticationHandler<UserAuthAuthenticationOptions>    
{
    public UserAuthHandler(IOptionsMonitor<UserAuthAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock) : base(options, logger, encoder, clock)
    {
    }
}
