Question

是否有人知道如何在网址中隐藏一些参数？

例如，您有一个url参数“culture”。它可以是“en，fr，it”。默认情况下，您的网站以“en”文化呈现，我们不会在网址中显示默认文化，但在其他文化情况下，参数“文化”必须出现在网址中。

http://myrendersite.net/barbikueue
http://myrendersite.net/fr/barbikueue

这是不同文化中的相同页面。如何基于默认的asp.net mvc路由系统做什么？

这会有所帮助：

ASP.NET mvc, localized routes and the default language for the user

Set Culture in an ASP.Net MVC app

您必须注册两条路线：

routes.MapRoute(
            name: "DefaultLang",
            url: "{language}/{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            constraints: new { language = "[a-z]{2}"}
        );

routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

创建一个继承Attribute的<{1}}：

ActionFilterAttribute

之后使用之前创建的属性创建public class LanguageActionFilterAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var routeDataKey = "language"; var defaultLang = "en"; var defaultCulture = "EN"; // if no language route param received if (filterContext.RouteData.Values[routeDataKey] == null /* && currentCulture != "en-EN" */) { // change culture to en-EN Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(string.Format("{0}-{1}", defaultLang, defaultCulture)); Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(string.Format("{0}-{1}", defaultLang, defaultCulture)); } else { /*if (currentCulture != "whatever") { //set culture to whatever }*/ } base.OnActionExecuting(filterContext); } }：

BaseController

现在所有[LanguageActionFilter] public abstract class BaseController : Controller { }都会继承Controllers，而不是BaseController

以下RouteConstraint可能有所帮助，

public class CultureConstraint : IRouteConstraint
{
    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values,
                      RouteDirection routeDirection)
    {
        if (routeDirection == RouteDirection.UrlGeneration)
        {
            return values[parameterName] != null &&
                   (route.Defaults[parameterName] == null ||
                    values[parameterName].ToString().ToLower() != route.Defaults[parameterName].ToString().ToLower());
        }
        return true;
    }
}

将其用作，

routes.MapRoute(
    name: "Culture",
    url: "{culture}/{controller}/{action}/{id}",
    defaults: new {culture = "en", controller = "Home", action = "Index", id = UrlParameter.Optional},
    constraints: new {culture = new CultureConstraint()}
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional}
);

此处约束仅适用于出站网址，并且当路线信息中的“文化”等于默认值时，会丢弃候选路线。

我使用了最简单的实现，因为你还没有发布你的路由代码，但这个想法应该有效。

希望这会有所帮助。
