在 MvcSiteMapProvider 中为具有动态参数的 DynamicNode 创建子节点

发布于 2024-10-02 01:10:49 字数 7999 浏览 0 评论 0原文

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,在动态节点下创建子节点(使用dynamicNodeProvider)时遇到问题。

我丢失了以下路线的面包屑:

Stores/5/Products/Edit/23

,其中网址模式为:

Stores/{storeID}/{controller}/{action}/{id }

当 ID 被省略时(即“新建”操作),它可以正常工作。但是,当指定 ID 时,它与路线不匹配,并且我的面包屑(使用 SiteMapPath 帮助程序)为空。

我的站点地图:(缩写)

<?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站点地图 xml 中创建子节点,如下所示动态节点的子节点。这根本不起作用,这些最终都成为“家”的孩子。我会在其中放置一个 ParentKey 属性,但这些属性将在每个商店中重复,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:

看来下一个选项是仅在我的 DynamicNodeProvider 中添加子节点。除了具有动态参数的节点之外,这种方法效果更好

(为了便于解释,对下面的内容进行了修改...)

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;
    }
}

总结

确实有效:Stores/5/Products/New
不起作用:Stores/5/Products/Edit/23
对于 Url 模式:Stores/{storeID}/{controller}/{action}/{id}

我希望能够执行的操作:

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

如何在节点上模仿旧 MvcSiteMapProvider 的dynamicParameters 属性这是一个动态节点的子节点?基本上我需要它在匹配路由时忽略“id”路由值。

希望我正确地解释了这一点,并且没有让您不知所措。谢谢!


更新:

这是基于 Jakub 的答案对我有用的解决方案。

在 MvcSiteMapProvider 2.x 中,您可以自行实现 ISiteMapNodeUrlResolver,而不必修改源代码。所以我基本上添加了具有dynamicParameters属性的能力

Class:

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:

<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>

Dynamic Node Provider:

DynamicNode node = new DynamicNode();
node.Attributes.Add("dynamicParameters", "id");

I am using MvcSiteMapProvider 2.2.1 (http://mvcsitemap.codeplex.com), and am having a problem with creating children under a dynamic node (using a dynamicNodeProvider) when those children have a dynamic parameter (id).

I am losing breadcrumbs for the following route:

Stores/5/Products/Edit/23

where the url pattern is:

Stores/{storeID}/{controller}/{action}/{id}

It works fine when the ID is left out (ie the "New" action). But when the ID is specified, it doesn't match the route, and my breadcrumbs (using the SiteMapPath helper) is blank.

My Sitemap: (abreviated)

<?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>

Area Registration:

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" }
        );
    }

First Attempt:

The first thing I tried was to create the child nodes right in the sitemap xml as children of the dynamic node. This didn't work at all, and these ended up being children of "Home". I would put a ParentKey attribute in there, except these will be repeated per store and thus there will be multiple parentkeys

<?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>

Second Attempt:

It seemed the next option was to just add the child nodes right in my DynamicNodeProvider. This worked much better except for the nodes that had dynamic parameters

(the below is modified for ease of explanation...)

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;
    }
}

In Summary

Does Work: Stores/5/Products/New
Doesn't Work: Stores/5/Products/Edit/23
For Url Pattern: Stores/{storeID}/{controller}/{action}/{id}

What I would like to be able to do:

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

How can I mimick the old MvcSiteMapProvider's dynamicParameters attribute on a node that is a child of a dynamicNode? Basically I need it to ignore the "id" route value when matching routes.

Hopefully I explained that properly, and didn't overwhelm you with information. Thanks!


UPDATE:

Here is the solution that worked for me based on Jakub's answer.

In MvcSiteMapProvider 2.x, you can make your own implementation of ISiteMapNodeUrlResolver instead of having to modify the source. So I basically added back in the ability to have the dynamicParameters attribute

Class:

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:

<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>

Dynamic Node Provider:

DynamicNode node = new DynamicNode();
node.Attributes.Add("dynamicParameters", "id");

我使用的是 1.x 版本。
我在动态参数方面也遇到了类似的问题。

我必须修改源代码 - 在 MvcSiteMapNode.cs 中进行更改。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dynamicParameters 的实际值是如何添加到routeValues 集合中的。

上述更改允许我在站点地图中定义动态参数(如“id”)并使用 Account/User/Edit/23 等链接创建面包屑。

我简要浏览了 2.x 版本,您应该能够应用类似的补丁。
希望它能帮助你...

I am using version 1.x.
I had a similar problem with dynamic parameters.

I had to modify the source code - made a change in MvcSiteMapNode.cs. This is the new implementation of Url property

    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;
        }
    }

Notice how actual values of dynamicParameters are added to routeValues collection.

The above change allowed me to define dynamic paremteres in sitemap (like 'id') and create breadcrumbs with links like Account/User/Edit/23.

I took a brief look at version 2.x and you should be able to apply similar patch.
Hope it will help you...
