我在global.asax
中有2条路线 routes.MapRoute(
"DefaultFriendlyUrl",
"Page/{FriendlyUrl}",
null,
new string[] { "MvcApplication2.Controllers" }
).RouteHandler = new FriendlyUrlRouteHandler();
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "index", id = UrlParameter.Optional },
new string[] { "MvcApplication2.Controllers" }
);
所以,FriendlyUrlRouteHandler处理所有我的/ Page / blablabla路由,并通过1个动作索引发送到PageController
public class FriendlyUrlRouteHandler : MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
var friendlyUrl = (string)requestContext.RouteData.Values["FriendlyUrl"];
PageItem page = null;
if (!string.IsNullOrEmpty(friendlyUrl))
page = PageManager.GetPageByFriendlyUrl(friendlyUrl);
if (page == null)
{
requestContext.RouteData.Values["controller"] = "home";
requestContext.RouteData.Values["action"] = "index";
requestContext.RouteData.Values["id"] = null;
}
else
{
requestContext.RouteData.Values["controller"] = "page";
requestContext.RouteData.Values["action"] = "index";
requestContext.RouteData.Values["id"] = page.PageID;
}
return base.GetHttpHandler(requestContext);
}
}
然后PageController获取我的页面的内容并显示它。但是MvcSiteMapProvider不会为这些页面显示面包屑
SiteMap.cs
public class SiteMap : DynamicNodeProviderBase
{
public override IEnumerable<DynamicNode> GetDynamicNodeCollection()
{
var returnValue = new List<DynamicNode>();
returnValue.Add(new DynamicNode() { Key = "id1", Title="CustomPage", Controller="Page", Action="Index" });
return returnValue;
}
}
我的CustomPage不存在于@ Html.MvcSiteMap()。SiteMapPath()中,但页面显示正确。我的代码中有什么问题? 所以我可以用breadcrumbs字符串构建自定义页面的树...

请提供您的Mvc.sitemap。
您的DynamicNode实例似乎缺少ParentKey。
