AbstractValidator Vs OnActionExecuting

Question

我在OnActionExecuting中设置了文化语言。但是我的验证方法(FluentValidation)甚至在OnActionExecuting执行之前就已经执行了。但我需要在OnActionExecuting之前，在AbstractValidator中需要的文化语言。

internal class MeetingAbstractValidator : AbstractValidator<MeetingAbstract>
{
    public MeetingAbstractValidator()
    {
        RuleFor(x => x.SPEPaperNumberText)
          .NotEmpty()
          .When(IfValueIsYes)
          .WithMessage(i18n_Models_Abstract.RequiredField);
     }
 }  

private bool IfValueIsYes(MeetingAbstract model)
  {
      return model.HasMaterialPublishedBySPEText.Equals(i18n_Models_Abstract.AbstractYes);
   }


public class LanguageFilterAttribute : ActionFilterAttribute
{
  public override void OnActionExecuting(ActionExecutingContext filterContext)
  {
      var request = filterContext.HttpContext.Request;
      string cultureName = null;
      var cultureCookie = request.Cookies["_culture"];
      if (request.UserLanguages != null)
           cultureName = cultureCookie != null ? cultureCookie.Value : 
                    request.UserLanguages[0];
           cultureName = CultureHelper.GetImplementedCulture(cultureName); // This is safe
           Thread.CurrentThread.CurrentCulture = new 
                               System.Globalization.CultureInfo(cultureName);
          Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

                base.OnActionExecuting(filterContext);
     }
}

如何处理这个问题？我可以覆盖OnActionExecuting吗？

Answer 1

我建议你使用Application_BeginRequest事件，并把你的文化逻辑放在那里。这在集成管道级别上执行，在MVC被事件委托来处理请求之前很久。
