ASP.NET MVC中的小写URL

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    // 添加自定义路由
    routes.Add(new LowercaseUrlRoute());

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

public class LowercaseUrlRoute : RouteBase
{
    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        var routeData = new RouteData();
        var request = httpContext.Request;

        // 获取当前URL并将其转换为小写
        var lowercaseUrl = request.Url.ToString().ToLower();

        // 重定向到小写URL
        httpContext.Response.RedirectPermanent(lowercaseUrl);

        return routeData;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return null;
    }
}
