使用多个路由的本地化ViewEngine

Question

我正在尝试制作一个简单的多语言网站。重写FindView以获得基于语言的文件很容易，我的问题出现在路由部分。

我想做的是：(有一个有两种语言的网站-pt-br和en-us，缩写为onlu pt和en-默认为pt)

用户类型www.mysite.com->会在用户头请求中找到语言，如果用户没有任何语言，他将被重定向到默认PT，因此最终结果将是葡萄牙语的www.mysite.com。如果他有en，他将被重定向到www.mysite.com/en/，结果将是英文视图。

如果用户键入www.mysite.com/pt/->，我会检查他是否想要默认值，并用葡萄牙语重定向到www.mysite.com。

我做了一个自定义引擎来获得基于该语言的正确视图。但由于路由问题，它不能100%工作。

就我而言，我正在尝试使用进行路由

routes.MapRoute(
"Localization", // Route name
"{lang}/{controller}/{action}", // URL with parameters
new { lang = "pt", controller = "Home", action = "Index" } //defaults
);

但这样一来，当有人键入/pt/时，就不会重定向到网站的根目录。

路线的另一个问题是，我不想让任何人输入控制器名称，我只想操作，我的网站只有一个主控制器，几乎没有操作。

另一个问题是，我想要一个不同的操作名称，比如英语的CONTACT和葡萄牙语的CONTATO，它们应该出现在地址栏上，比如www.mysite.com/CONTATO或www.mysite.com.cn/CONTACT

Mu Engine我确实基于这个解决方案http://www.counity.at/blog/2012/asp-net-mvc3-localization-using-culture-dependent-views/由Guido Breitenhuber

这是经过一些调整的代码(它还没有100%工作)

经过一段时间的努力，我找到了一个更容易、更快实现的解决方案。

刚刚在global.asax中一个接一个地映射了我想要的路由。如果你只有几个页面和语言，这会很有效，而且实现起来很快。

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute("Default-BR", "", new { controller = "Home", action = "Index" });
routes.MapRoute("Default-EN", "en", new { controller = "Home", action = "IndexEN" });
routes.MapRoute("HotelBR", "Hotel", new { controller = "Home", action = "Index" });
routes.MapRoute("HotelEN", "en/Hotel", new { controller = "Home", action = "IndexEN" });
routes.MapRoute("Apartamento", "Apartamento", new { controller = "Home", action = "Apartamentos" });
routes.MapRoute("Apartamentos", "Apartamentos", new { controller = "Home", action = "Apartamentos" });
routes.MapRoute("Apartments", "en/Apartments", new { controller = "Home", action = "ApartamentosEN" });
routes.MapRoute("Localizacao", "Localizacao", new { controller = "Home", action = "Localizacao" });
routes.MapRoute("Location", "en/Location", new { controller = "Home", action = "LocalizacaoEN" });
routes.MapRoute("Tarifa", "Tarifa", new { controller = "Home", action = "Tarifas" });
routes.MapRoute("Tarifas", "Tarifas", new { controller = "Home", action = "Tarifas" });
routes.MapRoute("Rates", "en/Rates", new { controller = "Home", action = "TarifasEN" });
routes.MapRoute("Reserva", "Reserva", new { controller = "Home", action = "Reservas" });
routes.MapRoute("Reservas", "Reservas", new { controller = "Home", action = "Reservas" });
routes.MapRoute("Booking", "en/Booking", new { controller = "Home", action = "ReservasEN" });
routes.MapRoute("Contato", "Contato", new { controller = "Home", action = "Contato" });
routes.MapRoute("Contact", "en/Contact", new { controller = "Home", action = "ContatoEN" });
