自定义语言处理EPiServer

Question

我有必要根据具体的规则来设置当前的语言。我需要访问当前页面和当前用户来做出决定。我查看了文档和上面写着，以便在PageBase上使用InitializeCulture方法。我的项目是使用MVC而不是WebForms，什么是InitializeCulture在MVC中的等价物？

您可以实现IAuthorizationFilter并在OnAuthorization中进行检查。在IActionFilter中也可以这样做，但OnAuthorization更早地被调用。您可以访问当前的HttpContext，从那里您可以获得当前的页面数据。

public class LanguageSelectionFilter : IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        // access to HttpContext
        var httpContext = filterContext.HttpContext;

        // the request's current page
        var currentPage = filterContext.RequestContext.GetRoutedData<PageData>();

        // TODO: decide which language to use and set them like below
        ContentLanguage.Instance.SetCulture("en");
        UserInterfaceLanguage.Instance.SetCulture("en");
    }
}

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        // register the filter in your FilterConfig file.
        filters.Add(new LanguageSelectionFilter());
    }
}
