我的自定义路线是:
routes.MapRoute(
name: "custom",
url: "{controller}/{action}/{category}/{subcategory}/{lowcategory}/{id}/{ignore}",
defaults: new { controller = "Home", action = "Index", category = UrlParameter.Optional, subcategory = UrlParameter.Optional, lowcategory = UrlParameter.Optional, id = UrlParameter.Optional,ignore = "" }
);
Mvc.sitemap
是:
<mvcSiteMapNode title="Home" controller="Home" action="Index" preservedRouteParameters="category,subcategory,lowcategory,id,ignore">
<mvcSiteMapNode title="About" controller="Home" action="About"/>
我的Index
功能是:
public ActionResult Index(string category, string subcategory, string lowcategory, int? id)
preservedRouteParameters
未显示node.Why?网址:http://localhost:59328/Home/Index/mobiles
预期网站地图:Home > mobiles
网址:http://localhost:59328/Home/Index/mobiles/htc
预期网站地图:Home > mobiles > htc
网址:http://localhost:59328/Home/Index/mobiles/htc/m8
预期网站地图:Home > mobiles > htc > m8
网址:http://localhost:59328/Home/Index/mobiles/htc/m8/12/title
预期的站点地图:Home > mobiles > htc > m8 > title
(注释ID未包含在站点地图中)
但实际的站点地图始终是Home
答案 0 :(得分:2)
SiteMap是一种层次结构。 MvcSiteMapProvider
的工作方式是匹配“当前”节点,然后使用层次结构构建返回主页的链接。它类似于ASP.NET中的Microsoft sitemap provider。
要获得所需的层次结构,您需要像使用Windows文件夹一样嵌套节点。
<mvcSiteMapNode title="Home" controller="Home" action="Index">
<mvcSiteMapNode title="Category" controller="Home" action="Index" preservedRouteParameters="category" key="category">
<mvcSiteMapNode title="Subcategory" controller="Home" action="Index" preservedRouteParameters="category,subcategory" key="subcategory">
<mvcSiteMapNode title="Lower Category" controller="Home" action="Index" preservedRouteParameters="category,subcategory,lowercategory" key="lowercategory">
<mvcSiteMapNode title="Title" controller="Home" action="Index" preservedRouteParameters="category,subcategory,lowercategory,id,ignore" key="titleid"/>
</mvcSiteMapNode>
</mvcSiteMapNode>
</mvcSiteMapNode>
<mvcSiteMapNode title="About" controller="Home" action="About"/>
</mvcSiteMapNode>
此外,路由中不可能使用多个可选段。您需要使用所需的段来构建路由。
routes.MapRoute(
name: "ID",
url: "Home/Index/{category}/{subcategory}/{lowercategory}/{id}/{ignore}",
defaults: new { controller = "Home", action = "Index", ignore = UrlParameter.Optional }
);
routes.MapRoute(
name: "LowerCategory",
url: "Home/Index/{category}/{subcategory}/{lowercategory}",
defaults: new { controller = "Home", action = "Index" }
);
routes.MapRoute(
name: "Subcategory",
url: "Home/Index/{category}/{subcategory}",
defaults: new { controller = "Home", action = "Index" }
);
routes.MapRoute(
name: "Category",
url: "Home/Index/{category}",
defaults: new { controller = "Home", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
最后,当使用preservedRouteParameters
时,您需要做更多的工作,以便根据URL动态更改标题。为此目的有一个SiteMapTitle属性,但其当前实现不允许将标题设置为当前节点和父节点。所以你需要做这样的事情来设置每个节点的标题:
using MvcSiteMapProvider.Web.Mvc;
public class HomeController : Controller
{
public ActionResult Index(
string category,
string subcategory,
string lowercategory,
int id = 0,
string ignore = "")
{
var currentNode = this.GetCurrentSiteMapNode();
if (currentNode != null)
{
switch (currentNode.Key)
{
case "titleid":
currentNode.Title = ignore;
currentNode.ParentNode.Title = lowercategory;
currentNode.ParentNode.ParentNode.Title = subcategory;
currentNode.ParentNode.ParentNode.ParentNode.Title = category;
break;
case "lowercategory":
currentNode.Title = lowercategory;
currentNode.ParentNode.Title = subcategory;
currentNode.ParentNode.ParentNode.Title = category;
break;
case "subcategory":
currentNode.Title = subcategory;
currentNode.ParentNode.Title = category;
break;
case "category":
currentNode.Title = category;
break;
}
}
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
return View();
}
public ActionResult About()
{
ViewBag.Message = "Your app description page.";
return View();
}
}
注意除preservedRouteParameters
之外还有另一个选项 - 您可以使用动态节点提供程序为每个类别,子类别,lowercategory等添加节点(并正确嵌套它们),然后每个节点都有自己的选项标题自动。有关示例,请参阅How To Make MvcSiteMapProvider Remember a User's Position。
