Question

当前节点为null，并且不呈现痕迹导览。 Sitemap文件如下：

<mvcSiteMapNode title="Reporting" iconClass="glyphicon glyphicon-stats" key="Reporting" area="Reporting" controller="Home" action="Index">
  <mvcSiteMapNode title="ReportFolder1" iconClass="glyphicon glyphicon-stats" key="ReportingReportFolder1" route="Reporting_Report" action="Report"> <!-- acts as a folder will just redirect to reporting home -->
    <mvcSiteMapNode title="Report1" description="abc" iconClass="glyphicon glyphicon-stats" key="Report1" route="Reporting_Report" action="Report" reportPath="/Reports/Report1"></mvcSiteMapNode>
  </mvcSiteMapNode>
  <mvcSiteMapNode title="ReportFolder2" iconClass="glyphicon glyphicon-stats" key="ReportingReportFolder2" route="Reporting_Report" action="Report"> <!-- acts as a folder  will just redirect to reporting home -->
    <mvcSiteMapNode title="Report2" description="abc" iconClass="glyphicon glyphicon-stats" key="Report2" route="Reporting_Report" action="Report" reportPath="/Reports/Report2"></mvcSiteMapNode>
  </mvcSiteMapNode>
</mvcSiteMapNode>

为此，我在该地区注册了一条特殊路线：

context.MapRoute(
    "Reporting_Report",
    "Reporting/Report/{*reportPath}",
    new { controller = "Home", action = "Report", reportPath = UrlParameter.Optional },
    new[] { "Web.Areas.Reporting.Controllers" }
);

context.MapRoute(
    "Reporting_default",
    "Reporting/{controller}/{action}/{id}",
    new { action = "Index", id = UrlParameter.Optional },
    new[] { "Web.Areas.Reporting.Controllers" }
);

控制器操作如下：

//
// GET: /Reporting/Report/
public ActionResult Report(string reportPath)
{
    if (String.IsNullOrWhiteSpace(reportPath))
        return RedirectToAction("Index");

    if (reportPath.StartsWith("/") == false)
        reportPath = "/" + reportPath;

    var viewModel = new HomeReportViewModel();
    viewModel.ReportPath = reportPath;

    return View(viewModel);
}

报告路径已成功传递到我的视图模型，一切正常。问题是站点地图节点不可用。 CurrentNode为null，并且不呈现面包屑。

节点标题的面包屑＆＃34;报告＆＃34;按原样呈现。

有什么建议吗？

我怀疑这是因为你正在解析＆＃34; Reports / Report1＆＃34;作为路径中的reportPath参数。

context.MapRoute(
    "Reporting_Report",
    "Reporting/Report/{*reportPath}",
    new { controller = "Home", action = "Report", reportPath = UrlParameter.Optional },
    new[] { "Web.Areas.Reporting.Controllers" }
);

在您的节点中，您将reportPath声明为＆＃34; / Reports / Report1＆＃34; （注意额外的正斜杠）。

<mvcSiteMapNode title="Report1" description="abc" iconClass="glyphicon glyphicon-stats" key="Report1" route="Reporting_Report" action="Report" reportPath="/Reports/Report1"></mvcSiteMapNode>

要匹配的参数，该值必须完全匹配（除了它是不区分大小写的匹配）。

MVC Sitemap CurrentNode为null，没有面包屑
