ModelState ErrorMessage文化定位

Question

ModelState Validation Culture on HttpPost

Error messages from ModelState not get localized

我读过这些问题，但他们没有解决我的问题。

我的问题是: ModelState验证errorMessages总是使用英语。本地化不起作用。

LocalizationAttribute.cs文件

public class LocalizationAttribute : ActionFilterAttribute
{ 
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.RouteData.Values["lang"] != null &&
            !string.IsNullOrWhiteSpace(filterContext.RouteData.Values["lang"].ToString()))
        {
            // set the culture from the route data (url)
            string lang = filterContext.RouteData.Values["lang"].ToString();
            Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang);
            Thread.CurrentThread.CurrentCulture = new CultureInfo(lang);
            CultureInfo.DefaultThreadCurrentCulture = new CultureInfo(lang);
            CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo(lang);
            filterContext.HttpContext.Session.Add("Culture", new CultureInfo(lang));
        }
        else
        {
            // get the browser culture
            string langHeader = filterContext.HttpContext.Request.UserLanguages[0];
            Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(langHeader);
            Thread.CurrentThread.CurrentCulture = new CultureInfo(langHeader);
            filterContext.RouteData.Values["lang"] = langHeader;
        }
        base.OnActionExecuting(filterContext);
    }
}

Web.config

<globalization culture="auto" uiCulture="auto" enableClientBasedCulture="false" />

Global.asax.cs

public class MvcApplication : HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        AutoMapperConfiguration.Configure();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        // Set the view engine
        ViewEngines.Engines.Clear();
        ViewEngines.Engines.Add(new MyCustomViewEngine(SiteSettings.Theme));
    }
}

FilterConfig.cs

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
        filters.Add(new LocalizationAttribute());
    }
}

在启动模型状态错误之前，我需要设置区域性，但我不知道如何做

Answer 1

您不会通过LocalizationAttribute实现您想要的结果，因为在OnActionExecuting(ActionExecutingContext filterContext)方法中同时设置Thread.CurrentThread.CurrentUICulture或Thread.CurrentThread.CurrentCulture已经太晚了。

当OnActionExecuting被触发时，程序集区域性已经设置了ModelState错误。

解决方案1

在基本控制器中重写Initialize(System.Web.Routing.RequestContext requestContext)方法，并在Thread.CurrentThread.CurrentUICulture和Thread.CurrentThread.CurrentCulture中设置想要的区域性。

解决方案2

在Application_BeginRequest(object sender, EventArgs e)中重写Global.asax，并在Thread.CurrentThread.CurrentUICulture和Thread.CurrentThread.CurrentCulture中设置所需的区域性。
