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 处理我所有的 /Page/blablabla 路由并使用 1 个操作索引发送到 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 为我的页面获取内容并显示它。但是 MvcSiteMapProvider 不显示这些页面的面包屑
站点地图.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;
}
}
而且我的 CustomPage 不存在于 @Html.MvcSiteMap().SiteMapPath() 中,但页面显示正确。我的代码有什么问题?所以我不能在面包屑字符串中构建我的自定义页面的树......
