我正在尝试创建自己的过滤器属性以支持多语言。这个想法很简单。URL 代表语言。
- *http://host.ext/ en /rest_of_the_url* 将以英文打开，并且
- *http://host.ext/ hy /rest_of_the_url* 将以亚美尼亚语打开。
问题是在运行时它说 MultilingualActionFilterAttribute
这是错误文本“给定的过滤器实例必须实现以下一个或多个过滤器接口：IAuthorizationFilter、IActionFilter、IResultFilter、IExceptionFilter。”
在这里，我将其用作全局过滤器。
namespace TIKSN.STOZE.WebApp
{
public class FilterConfig
{
public static void RegisterGlobalFilters(System.Web.Mvc.GlobalFilterCollection filters)
{
filters.Add(new TIKSN.STOZE.Common.MultilingualActionFilterAttribute());
filters.Add(new System.Web.Mvc.HandleErrorAttribute());
}
}
}
我在这里定义它。
namespace TIKSN.STOZE.Common
{
public class MultilingualActionFilterAttribute : System.Web.Mvc.ActionFilterAttribute
{
public override void OnActionExecuting(System.Web.Mvc.ActionExecutingContext filterContext)
{
string language = System.Convert.ToString(filterContext.RouteData.Values["language"]);
System.Diagnostics.Debug.Print("Requested language is '{0}'", language);
language = Helper.PickUpSupportedLanguage(language);
System.Diagnostics.Debug.Print("Supported language is '{0}'", language);
if (language == string.Empty)
{
filterContext.HttpContext.Response.RedirectToRoutePermanent(new { language = Common.Properties.Settings.Default.DefaultLanguageCode });
}
language = Helper.TryToPickUpSupportedLanguage(language);
System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture(language);
System.Threading.Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.GetCultureInfo(language);
}
}
}
