MVC sitemapcurrentnode是空的，没有面包屑

本文关键字：面包 sitemapcurrentnode MVC | 更新日期: 2023-09-27 17:50:13

当前节点为空，不呈现breadcrumb。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，我在该区域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" }
);

控制器动作如下:

//
// 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);
}

报告路径成功地传递给我的视图模型，一切正常工作。问题是站点地图节点不可用。CurrentNode为null，则不呈现breadcrumb。

节点标题为"Reporting"的breadcrumb按原样呈现。

有什么建议吗?

我怀疑这是因为您将"Reports/Report1"解析为路由之外的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"/Reports/Report1"(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>

要匹配参数，值必须完全匹配(不区分大小写的匹配除外)
