自定义错误仅在本地显示，但不在远程服务器上

Question

我为我的 ASP.NET MVC 应用程序创建了自定义错误，由于某种原因，它们只显示在我的本地计算机上，但是当我在远程服务器上部署我的应用程序时，会显示默认的 IIS 错误页面（404 和 500）我想了解为什么会这样。这是我的应用配置：

web.config

<system.web>
    ...
        <customErrors mode="On" defaultRedirect="~/ServerError">
          <error statusCode="404" redirect="~/NotFound" />
        </customErrors>
    ...
</system.web>

路由配置

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

    routes.MapRoute(
        "Error - 404",
        "NotFound",
        new { controller = "Error", action = "NotFound" }
    );

    routes.MapRoute(
        "Error - 500",
        "ServerError",
        new { controller = "Error", action = "ServerError" }
    );

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

错误控制器：

public class ErrorController : Controller
{
    [AllowAnonymous]
    public ActionResult ServerError()
    {
        Response.StatusCode = (int)HttpStatusCode.InternalServerError;

        return View();
    }

    [AllowAnonymous]
    public ActionResult NotFound()
    {
        Response.StatusCode = (int)HttpStatusCode.NotFound;

        return View();
    }
}

Global.asax

protected void Application_Error(object sender, EventArgs e)
{
    Response.TrySkipIisCustomErrors = true;
}

本地机器 IIS 配置和远程 IIS 配置看起来很相似，但也许我遗漏了一些东西，我也必须正确配置它。

感谢您的帮助。

这样就解决了问题：

public class ErrorController : Controller
{
    [AllowAnonymous]
    public ActionResult ServerError()
    {
        Response.StatusCode = (int)HttpStatusCode.InternalServerError;

        Response.TrySkipIisCustomErrors = true;

        return View();
    }

    [AllowAnonymous]
    public ActionResult NotFound()
    {
        Response.StatusCode = (int)HttpStatusCode.NotFound;

        Response.TrySkipIisCustomErrors = true;

        return View();
    }
}
