我正在使用MvcSiteMapProvider 2.2.1(http://mvcsitemap.codeplex.com),并且当这些子节点具有动态参数(id)时,在动态节点(使用dynamicNodeProvider)下创建子节点时遇到问题.
我正在丢失以下路线的面包屑:
商店/ 5 /产品/编辑/ 23
url模式的位置是:
存储/ {STOREID}/{控制器}/{行动}/{ID}
当ID被省略时(即"新"动作),它可以正常工作.但是当指定ID时,它与路径不匹配,并且我的面包屑(使用SiteMapPath帮助程序)是空白的.
我的站点地图:(已删除)
<?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>
区域注册:
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" }
);
}
第一次尝试:
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.这根本不起作用,最终成为"家"的孩子.我会在其中放置一个ParentKey属性,除了这些将在每个商店重复,因此将有多个父键
<?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:
看起来下一个选择就是在我的DynamicNodeProvider中添加子节点.除了具有动态参数的节点外,这种方法效果更好
(为便于说明,以下内容进行了修改......)
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;
}
}
综上所述
是否有效:商店/ 5 /产品/新功能
不起作用:商店/ 5 /产品/编辑/ 23
对于网址格式:商店/ {storeID}/{controller}/{action}/{id}
我希望能做什么:
editNode.Attributes.Add("isDynamic", "true");
editNode.Attributes.Add("dynamicParameters", "id");
如何在作为dynamicNode子节点的节点上模仿旧的MvcSiteMapProvider的dynamicParameters属性？基本上我需要它在匹配路由时忽略"id"路由值.
希望我能正确解释,并没有用信息压倒你.谢谢!
更新:
以下是基于Jakub答案的解决方案.
在MvcSiteMapProvider 2.x中,您可以自己实现ISiteMapNodeUrlResolver,而不必修改源代码.所以我基本上补充了拥有dynamicParameters属性的能力
类:
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));
}
}
}
Web.config文件:
<siteMap defaultProvider="MvcSiteMapProvider" enabled="true">
<providers>
<clear/>
<add name="MvcSiteMapProvider"
type="MvcSiteMapProvider.DefaultSiteMapProvider, MvcSiteMapProvider"
siteMapFile="~/Mvc.Sitemap"
securityTrimmingEnabled="true"
attributesToIgnore="visibility,dynamicParameters"
scanAssembliesForSiteMapNodes="true"
siteMapNodeUrlResolver="ControlPanel.CustomSiteMapNodeUrlResolver, ControlPanel"
siteMapNodeVisibilityProvider="MvcSiteMapProvider.FilteredSiteMapNodeVisibilityProvider, MvcSiteMapProvider" />
</providers>
</siteMap>
动态节点提供者:
DynamicNode node = new DynamicNode();
node.Attributes.Add("dynamicParameters", "id");
我使用的是1.x版.我有动态参数的类似问题.
我不得不修改源代码 - 在MvcSiteMapNode.cs中进行了更改.这是Url属性的新实现
public override string Url
{
get
{
if (!string.IsNullOrEmpty(this.url))
return this.url;
RequestContext ctx;
if (HttpContext.Current.Handler is MvcHandler)
ctx = ((MvcHandler)HttpContext.Current.Handler).RequestContext;
else
ctx = new RequestContext(new HttpContextWrapper(HttpContext.Current), new RouteData());
var routeValues = new RouteValueDictionary(RouteValues);
foreach (var key in DynamicParameters)
routeValues.Add(key, ctx.RouteData.Values[key]);
return new UrlHelper(ctx).Action(Action, Controller, routeValues);
}
set
{
this.url = value;
}
}
请注意如何将dynamicParameters的实际值添加到routeValues集合中.
上述更改允许我在站点地图中定义动态paremteres(如'id')并使用Account/User/Edit/23等链接创建面包屑.
我简要介绍了2.x版,您应该能够应用类似的补丁.希望它能帮到你......
