IIS 10上的OWIN WebApi項目在所有操作上給出404

Question

我有一個OWIN WebAPI項目，該項目可在OwinSelfHost中使用，但在IIS 10上托管時始終會顯示404，唯一起作用的是初始頁面public / index.html。 我在Windows 10計算機上運行IIS 10。 我正在使用Dapper，Npgsql和Postgresql數據庫。

我嘗試了一些通過谷歌搜索閱讀的技巧，到目前為止，還沒有運氣，這是我的Web.config：

Answer 1

您必須將OwinHttpHandler添加到管道中：

<handlers>
       <add name="Owin" verb="*" path="*" type="Microsoft.Owin.Host.SystemWeb.OwinHttpHandler, Microsoft.Owin.Host.SystemWeb" />
 </handlers>
