別の可能な解決策は、カスタムルートを作成することです
public class ParamsEnabledRoute : RouteBase
{
private Route route;
public ParamsEnabledRoute(string url)
{
route = new Route(url, new MvcRouteHandler());
}
public override RouteData GetRouteData(HttpContextBase context)
{
var data = route.GetRouteData(context);
if (data != null)
{
var paramName = (string)data.Values["paramname"] ?? "parameters";
var parameters = context.Request.QueryString.AllKeys.ToDictionary(key => key, key => context.Request.QueryString[key]);
data.Values.Add(paramName, parameters);
return data;
}
return null;
}
public override VirtualPathData GetVirtualPath(RequestContext context, RouteValueDictionary rvd)
{
return route.GetVirtualPath(context, rvd);
}
}
使用法:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.Add(new ParamsEnabledRoute("ParamsEnabled/{controller}/{action}/{paramname}"));
}
コントローラ:
public class HomeController : Controller
{
public ActionResult Test(Dictionary<string, string> parameters)
{
}
}
URL:
http://localhost/ParamsEnabled/Home/Test/parameteres?param1=value1¶m2=value2
ルート属性:
public class RouteDataValueAttribute : ActionMethodSelectorAttribute
{
private readonly RouteDataValueAttributeEnum type;
public RouteDataValueAttribute(string valueName)
: this(valueName, RouteDataValueAttributeEnum.Required)
{
}
public RouteDataValueAttribute(string valueName, RouteDataValueAttributeEnum type)
{
this.type = type;
ValueName = valueName;
}
public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo)
{
if (type == RouteDataValueAttributeEnum.Forbidden)
{
return controllerContext.RouteData.Values[ValueName] == null;
}
if (type == RouteDataValueAttributeEnum.Required)
{
return controllerContext.RouteData.Values[ValueName] != null;
}
return false;
}
public string ValueName { get; private set; }
}
public enum RouteDataValueAttributeEnum
{
Required,
Forbidden
}
