由于错误的 web.config 设置，默认文档无法正常工作

Question

我正在处理部署在 IIS 8.5 上的遗留应用程序，它应该自动显示 default.aspx 页面，但它不会显示 404 错误。为了测试，我在同一台机器上添加了一个新网站并上传了一个空的 default.aspx 页面，这有效。当我在新网站再次粘贴 web.config 时，再次出现相同的错误 404。

我尝试在 web.config 中手动添加默认页面，但同样的问题。

所以这看起来像是 web.config 文件中的配置错误，请查看下面的内容 web.config，如果您发现任何问题请告诉我。

上面的代码，我怀疑在线

    <handlers>
      <remove name="ScriptResource" />
      <add name="*.aspx_*" path="Test_*.aspx" verb="*" type="Events.WebFormHandlerFactory" />
      <add name="HTMLHandler" path="*.aspx" verb="GET,HEAD,POST,DEBUG" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.5,bitness32" type="System.Web.UI.PageHandlerFactory" />
    </handlers>

它的 runtimeVersion 是 4.5，这也是目标框架，但 scriptProcessor 有 v4.0.30319，这闻起来像个错误。

非常感谢任何意见。

Answer 1

你能试试只有一个 system.webServer 条目吗？

Answer 2

在 web.config 中没有任何问题，这个问题是在我在现有的 Web 表单应用程序中启用 MVC 位后才出现的。

MVC 应用程序覆盖基于 URL 的现有 Web 表单扩展名，因此当请求没有扩展名 (.aspx) 时，此请求将映射到默认路由，即域。com/Home/Index 因此在我的应用程序中不可用我看到 404 未找到。

现在为了设置或阻止此 MVC 默认值，我们可以使用

routes.IgnoreRoute("");

这里的代码很有魅力。

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    routes.IgnoreRoute("");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

希望这会节省您的时间。
