Nancy.Owin 对比 Nancy.Hosting.Self 与顶架

Question

1) 使用这两种不同的软件包进行设置有什么区别？一个比另一个更受支持吗？

我有一个使用 Nancy.Hosting.Self 的项目，但没有找到任何关于如何设置 windows 身份验证的文章，而我确实找到了 Nancy.Owin 作为中间件的文章。我现在已经切换到 Nancy.owin.

这里有几个不同的问题。

2) jsonformatter 可以在 nancy 引导程序中配置，也可以在 owin 端点 topshelf 中配置。我应该在哪里配置格式化程序？如果在 topshelf owin 端点中配置，这是否也会应用于 nancy 引导程序？

3) 对于 topshelf 中的 nancy 端点，可以选择设置防火墙规则和 url 保留。我在 owin 端点找不到这个。
