在MvcSiteMapProvider中为动态节点创建具有动态参数的子节点

我正在使用MVCSitemApprovider2.2.1(http://mvcsitemap.codeplex.com),并且在动态节点下创建子节点(使用dynamicNodeProvider)时遇到问题,因为这些子节点具有动态参数(id)。

我正在丢失以下路线的面包屑:

商店/5/产品/Edit/23

存储/{storeID}/{controller}/{action}/{id}

当ID被遗漏时(即“New”动作),它工作得很好。但是当指定ID时,它与路由不匹配,并且我的breadcrumbs(使用SiteMapPath助手)为空。

我的站点地图: (删节)

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-2.0">
    <mvcSiteMapNode title="Home" controller="Dashboard" action="Index" changeFrequency="Always" updatePriority="Normal">
        <mvcSiteMapNode title="My Account" controller="Account" action="Index" key="Account" />
        <mvcSiteMapNode title="My Stores" area="Stores" controller="Home" action="Index" visibilityProvider="ControlPanel.Areas.Stores.StoreAreaVisibilityProvider, ControlPanel"  >
            <mvcSiteMapNode title="Store" action="Index" dynamicNodeProvider="ControlPanel.Areas.Stores.StoreAreaNodeProvider, ControlPanel" />
        </mvcSiteMapNode>
    </mvcSiteMapNode>
</mvcSiteMap>

public override void RegisterArea(AreaRegistrationContext context)
{
        context.MapRoute(
            "Store_Index",
            "Stores",
            new { action = "Index", controller = "Home" },
            new string[] { "ControlPanel.Areas.Stores.Controllers" }
            );

        context.MapRoute(
            "Store_default",
            "Stores/{storeID}/{controller}/{action}/{id}",
            new { action = "Index", controller = "Manage", id = UrlParameter.Optional },
            new { storeID = @"\d+" },
            new string[] { "ControlPanel.Areas.Stores.Controllers" }
        );
    }

首次尝试:

我尝试的第一件事是在sitemap xml中创建子节点作为动态节点的子节点。这根本不管用,结果这些孩子成了“家”的孩子。我会在其中放置一个ParentKey属性,除了这些属性将在每个存储中重复,因此将有多个ParentKey

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-2.0">
  <mvcSiteMapNode title="Home" controller="Dashboard" action="Index" changeFrequency="Always" updatePriority="Normal">
    <mvcSiteMapNode title="My Account" controller="Account" action="Index" key="Account" />
    <mvcSiteMapNode title="My Stores" area="Stores" controller="Home" action="Index" visibilityProvider="ControlPanel.Areas.Stores.StoreAreaVisibilityProvider, ControlPanel"  >
      <mvcSiteMapNode title="Store" action="Index" dynamicNodeProvider="ControlPanel.Areas.Stores.StoreAreaNodeProvider, ControlPanel">
        <mvcSiteMapNode title="Products" area="Stores" controller="Products" action="Index">
          <mvcSiteMapNode title="Edit" area="Stores" controller="Products" action="Edit"/>
          <mvcSiteMapNode title="New" area="Stores" controller="Products" action="Edit"/>
        </mvcSiteMapNode>
      </mvcSiteMapNode>
    </mvcSiteMapNode>
  </mvcSiteMapNode>
</mvcSiteMap>

第二次尝试:

下一个选项似乎是直接在DynamicNodeProvider中添加子节点。除了具有动态参数的节点外,这种方法的效果更好

(为了便于解释,修改了下面的内容…)

public class StoreAreaNodeProvider : IDynamicNodeProvider
{
    public IEnumerable<DynamicNode> GetDynamicNodeCollection()
    {
        var nodes = new List<DynamicNode>();

        foreach (var store in repo.GetStores())
        {
            DynamicNode node = new DynamicNode();
            node.Title = store.Name;
            node.Area = "Stores";
            node.Controller = "Manage";
            node.Action = "Index";
            node.RouteValues.Add("storeID", store.StoreID);
            node.Key = "Store_" + store.StoreID.ToString();

            nodes.Add(node);

            //Child of node
            DynamicNode productsNode = new DynamicNode();
            productsNode.Title = "Products";
            productsNode.Area = "Stores";
            productsNode.Controller = "Products";
            productsNode.Action = "Index";
            productsNode.RouteValues.Add("storeID", store.StoreID);
            productsNode.ParentKey = String.Format("Store_{0}", store.StoreID.ToString());
            productsNode.Key = String.Format("Store_{0}_Products", store.StoreID.ToString());

            nodes.Add(productsNode);

            //child of productsNode
            DynamicNode editNode = new DynamicNode();
            editNode.Title = "Edit";
            editNode.Area = "Stores";
            editNode.Action = "Edit";
            editNode.Controller = "Products";
            editNode.RouteValues.Add("storeID", store.StoreID);
            //I can't add the RouteValue "ID" here because it is dynamic
            //I would have do loop through every product for this store with
            //another dynamic node provider, but that seems terribly inefficient and stupid
            editNode.ParentKey = String.Format("Store_{0}_Products", store.StoreID.ToString());
            editNode.Attributes.Add("visibility", "SiteMapPathHelper,!*");

            nodes.Add(editNode);
        }

        return nodes;
    }
}

总结

是否有效:
不起作用:
对于Url模式: 存储/{storeID}/{controller}/{action}/{id}

我想做的是:

editNode.Attributes.Add("isDynamic", "true");
editNode.Attributes.Add("dynamicParameters", "id");

如何在dynamicode的子节点上模仿旧的mvcsitemprovider的dynamicParameters属性?基本上,我需要它在匹配路由时忽略“id”路由值。

namespace ControlPanel
{
    public class CustomSiteMapNodeUrlResolver : ISiteMapNodeUrlResolver
    {
        public virtual string ResolveUrl(MvcSiteMapNode mvcSiteMapNode, string area, string controller, string action, IDictionary<string, object> routeValues)
        {
            RequestContext ctx;
            if (HttpContext.Current.Handler is MvcHandler)
                ctx = ((MvcHandler)HttpContext.Current.Handler).RequestContext;
            else
                ctx = new RequestContext(new HttpContextWrapper(HttpContext.Current), new RouteData());

            //Begin Added Code
            if (mvcSiteMapNode["dynamicParameters"] != null)
            {
                foreach (var item in mvcSiteMapNode["dynamicParameters"].Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
                {
                    var dp = item.Trim();
                    routeValues[da] = ctx.RouteData.Values[dp];
                }
            }
            //End Added Code

            return new UrlHelper(ctx).Action(action, controller, new RouteValueDictionary(routeValues));
        }
    }
}
