在Rotativa生成的PDF中显示页眉和页脚

Question

我正在尝试在Rotativa库生成的PDF中指定页眉和页脚.正如作者在这里回答的那样,应该可以使用CSS(这里描述).但是,我无法做到这一点.

我在meta标签中加载了样式表:

<link href="print.css" rel="stylesheet" type="text/css" media="print" />

在底部的样式表中:

@page {
    @top-left {
        content: "TOP SECRET";
        color: red
    }
    @bottom-right {
        content: counter(page);
        font-style: italic
    }
}

然后通过以下方式生成PDF:

public ActionResult ShowPdf()
{
     var model = new Model();
     return new ViewAsPdf("view.cshtml", model)
                {
                    FileName = "Report.pdf",
                    CustomSwitches = "--print-media-type"
                };
}

然后,PDF的页眉和页脚中没有任何内容.有任何想法吗？

我找到了wkhtmltopdf的文档,并在那里描述了如何管理页眉和页脚.

基本上你可以添加--header-center "text"(或类似的开关)到参数列表,这就是全部.

因此,与Rotativa一起使用它将是:

public ActionResult ShowPdf()
{
     var model = new Model();
     return new ViewAsPdf("view.cshtml", model)
                {
                    FileName = "Report.pdf",
                    CustomSwitches = "--print-media-type --header-center \"text\""
                };
}

(我不知道是否--print-media-type有必要.)

如果你想在页眉/页脚中显示一个View而不是文本,那么你可以这样做:

public ActionResult ViewPDF()
{
      string customSwitches = string.Format("--print-media-type --allow {0} --footer-html {0} --footer-spacing -10",
                Url.Action("Footer", "Document", new { area = ""}, "https"));


     return new ViewAsPdf("MyPDF.cshtml", model)
                {
                    FileName = "MyPDF.pdf",
                    CustomSwitches = customSwitches
                };
}

[AllowAnonymous]
public ActionResult Footer()
{
    return View();
}

不要忘记在Footer操作上添加[AllowAnonymous]属性,否则Rotatina无法访问路径.

这是我的做法（完整）：

public ActionResult PrintPDF(int? selectedSiteRotaId, int selectedSiteId)
{
    string footer = "--footer-center \"Printed on: " + DateTime.Now.Date.ToString("MM/dd/yyyy") + "  Page: [page]/[toPage]\"" + " --footer-line --footer-font-size \"9\" --footer-spacing 6 --footer-font-name \"calibri light\"";

    return new ActionAsPdf("RenderPDF", new { selectedSiteRotaId = selectedSiteRotaId, selectedSiteId = 7 }) 
    {
        FileName = "PDF_Output.pdf",
        PageOrientation = Orientation.Landscape,
        MinimumFontSize = 10, 
        //PageMargins  = new Margins(5,5,5,5),
        PageSize = Size.A3,
        CustomSwitches = footer
    };

    //var pdfResult = new ActionAsPdf("RenderPDF", new { selectedSiteRotaId = selectedSiteRotaId, selectedSiteId = 7 })
    //{
    //    FileName = "PDF_Output.pdf",
    //    PageOrientation = Orientation.Landscape,
    //    MinimumFontSize = 10
    //};

    //var binary = pdfResult.BuildPdf(this.ControllerContext);

    //return File(binary, "application/pdf");
}


public ActionResult RenderPDF(int? selectedSiteRotaId, int selectedSiteId)
{
    return RedirectToAction("Index", "PrintPDF", new { selectedSiteRotaId = selectedSiteRotaId, selectedSiteId = 7 });
}
