不使用Identity的.net core 2.2应用程序的JWT身份验证

Question

我在这里关注这篇文章： https ： //fullstackmark.com/post/13/jwt-authentication-with-aspnet-core-2-web-api-angular-5-net-core-identity-and-facebook-登录 ，我遇到了我的JWT持票人令牌没有授权我的用户的障碍。 我得到一个有效的JWT - 请参见截图：

这是我调用api来检索该令牌的屏幕截图：

这是我在邮递员中获得401的截图。

我已经阅读了有关该文章的所有评论，其他一些人因各种原因获得了401，但我对所有这些问题感到满意并且他们不是我的。

想知道另一组眼睛是否有助于发现正在发生的事情。 从根本上说，我没有使用Identity来登录我的东西。 我更喜欢使用自己的表结构和登录机制，但我不认为这是我的问题的根源。

这是我的startup.cs文件。 这里有人跳出来吗？ 不确定下一步该去哪里。

public class Startup
{
    private const string SecretKey = "iNivDmHLpUA223sqsfhqGbMRdRj1PVkH";
    private readonly SymmetricSecurityKey _signingKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(SecretKey));

    }

        // In production, the Angular files will be served from this directory

        });

        services.AddDbContext<MyHomeBuilderContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("MyHomeBuilderContext"))

我绿化了一个全新的项目，并逐步完成了事情，找到了罪魁祸首。 原来有两个。

1）在VS 2019中，您正在调试授权工作。 对此没有超级兴奋。 我宁愿能够在应用程序运行时进行授权，但不一定要调试 - 如果有解决方法，我很乐意听到它。 2）我的app.UseAuthentication()下面是我在Configure() app.UseAuthentication()中的一些其他声明，显然是订单问题 - 任何人都可以解释一下吗？

我会留下这个以防其他人遇到这个问题，如果有人对我的问题有一些想法 - 请求我喜欢接受教育:)
