ASP.NET MVC请求特殊静态文件返回404 Not Found

今天在请求静态的json档案以及woff2档案，会返回404错误，需要在Web.Config里修改：

  <system.webServer>
     <modules>
       <remove name="FormsAuthentication" />
     </modules>
     <handlers>
       <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
     </handlers>
     <staticContent>
       <mimeMap fileExtension=".json" mimeType="application/json; charset=UTF-8" />
       <mimeMap fileExtension=".woff2" mimeType="application/font-woff2" />
     </staticContent>
   </system.webServer>
