Question

我正在尝试制作一个简单的多语言网站。重写FindView以根据语言获取文件很容易，我的问题出现在路由部分。

我想做的是:(有一个网站有2种语言 - pt-br和en-us，让缩写为onlu pt和en - 默认为PT）

用户类型www.mysite.com - ＆gt;会在用户标头请求中找到这些语言，如果用户没有这些语言，他将被重定向到默认的PT，因此最终结果将是葡萄牙语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。

如果用户输入www.mysite.com/pt/ - ＆gt;我会检查他是否想要默认值，并将用葡萄牙语重定向到www.mysite.com。

我做了一个自定义引擎，以根据语言获得正确的视图。但由于路由问题，它不能100％工作。

在我的情况下，我试图用

路由

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

但是有了这个，当有人输入/ pt /不会重定向到网站的根目录时。

该路线的另一个问题是我不想让任何人输入控制器名称，我只想要动作，我的网站只有一个家庭控制器，几乎没有动作。

另一个问题是，我需要一个不同的动作名称，例如英语的CONTACT和葡萄牙语的CONTATO，它们应该出现在地址栏上，如www.mysite.com/Contato或www.mysite.com/en/Contact

我根据http://www.counity.at/blog/2012/asp-net-mvc3-localization-using-culture-dependent-views/

这是带有一些调整的代码（它还没有100％工作）

好吧，经过一段时间尝试以最佳方式完成后，我发现一种解决方案更容易，更快速地实施。

只是在global.asax中逐一映射我想要的路由。如果您只有很少的页面和语言，这将有效，并且可以快速实施。

    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" });

使用多个路由的本地化ViewEngines
