MVC4 中的双语 404 页面

Question

我关注了this answer 以获得一个正常运行的双语 MVC4 网站。我制作了也是双语的 404 错误页面，但是当我输入错误的链接时，它要么转到英文版，要么显示 MVC 库存 404 页面。我尝试了很多解决方案，包括两种解决方案found here，但似乎没有任何帮助。

Answer 1

Global.asax

protected void Application_Error(object sender, EventArgs e)
        {
            // Do whatever you want to do with the error

            //Show the custom error page...
            Server.ClearError();
            var routeData = new RouteData();
            routeData.Values["controller"] = "Error";

            if ((Context.Server.GetLastError() is HttpException) && ((Context.Server.GetLastError() as HttpException).GetHttpCode() != 404))
            {
                routeData.Values["action"] = "Index";
            }
            else
            {
                // Handle 404 error and response code
                Response.StatusCode = 404;
                routeData.Values["action"] = "NotFound404";
            }
            Response.TrySkipIisCustomErrors = true; // If you are using IIS7, have this line
            IController errorsController = new ErrorController();
            HttpContextWrapper wrapper = new HttpContextWrapper(Context);
            var rc = new System.Web.Routing.RequestContext(wrapper, routeData);
            errorsController.Execute(rc);
        }

只需创建一个 Error 控制器并创建 NotFound404 视图，您在上面输入的任何内容作为您创建的视图

它对我有用。

成功地让它工作。感谢@r.vengadesh 和我在问题中提供的链接。无论如何，这是其中的文件和修改...

Global.asax：

protected void Application_Error(object sender, EventArgs e)
{
    Server.ClearError();
    var routeData = new RouteData();
    HttpContextBase currentContext = new HttpContextWrapper(HttpContext.Current);
    var culture = RouteTable.Routes.GetRouteData(currentContext).Values["culture"];
    routeData.Values["culture"] = culture;
    routeData.Values["controller"] = "Error";

    if ((Context.Server.GetLastError() is HttpException) && ((Context.Server.GetLastError() as HttpException).GetHttpCode() != 404))
    {
        routeData.Values["action"] = "Index";
    }
    else
    {
        Response.StatusCode = 404;
        routeData.Values["action"] = "page404";
    }
    IController errorController = new ErrorController();
    HttpContextWrapper wrapper = new HttpContextWrapper(Context);
    var rc = new System.Web.Routing.RequestContext(wrapper, routeData);
    errorController.Execute(rc);
}

还有 RouteConfig：

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

        routes.MapRoute(
            name: "DefaultWithCulture",
            url: "{culture}/{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            constraints: new { culture = new CultureConstraint(defaultCulture: "en", pattern: "[a-z]{2}") }
        );

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

        // Catch-all route (for routing misses)
        routes.MapRoute(
            name: "Localized-404",
            url: "{culture}/{*url}",
            defaults: new { controller = "Error", action = "page404" },
            constraints: new { culture = new CultureConstraint(defaultCulture: "en", pattern: "[a-z]{2}") }
        );

        routes.MapRoute(
            name: "Default-404",
            url: "{*url}",
            defaults: new { culture = "en", controller = "Error", action = "page404" }
        );
    }
}

当然，你需要有 ErrorController，里面有一个 page404。
