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>
