Displaying headers and footers in a PDF generated by Rotativa
提问by bpiec
I'm trying to specify headers and footers in a PDF generated by Rotativa library. As the author answered hereit should be possible using CSS (described here). However, I'm not able to do this.
我正在尝试在 Rotativa 库生成的 PDF 中指定页眉和页脚。正如作者在此处回答的那样，应该可以使用 CSS（此处描述）。但是，我无法做到这一点。
I have a stylesheet loaded in the meta tag:
我在元标记中加载了一个样式表：
<link href="print.css" rel="stylesheet" type="text/css" media="print" />
And in the stylesheet at the bottom:
在底部的样式表中：
@page {
@top-left {
content: "TOP SECRET";
color: red
}
@bottom-right {
content: counter(page);
font-style: italic
}
}
And then generating PDF by:
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"
};
}
And then nothing appears in the header and footer of the PDF. Any ideas?
然后在 PDF 的页眉和页脚中什么也没有出现。有任何想法吗？

I've found a documentation of wkhtmltopdfand it is described there how to manage headers and footers.
我找到了wkhtmltopdf的文档，其中描述了如何管理页眉和页脚。
Basically you can just add --header-center "text"(or similar switches) to the argument list and that's all.
基本上，您可以将--header-center "text"（或类似的开关）添加到参数列表中，仅此而已。
So using it with Rotativa it would be:
因此，将它与 Rotativa 一起使用将是：
public ActionResult ShowPdf()
{
var model = new Model();
return new ViewAsPdf("view.cshtml", model)
{
FileName = "Report.pdf",
CustomSwitches = "--print-media-type --header-center \"text\""
};
}
(I don't know if --print-media-typeis necessary.)
（不知道有--print-media-type没有必要。）

If you wanted to display a View instead of text in the header/footer then you can do so like this:
如果你想在页眉/页脚中显示一个视图而不是文本，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();
}
Don't forget to add the [AllowAnonymous] attribute on the Footer action otherwise Rotatina can't get access to the path.
不要忘记在页脚操作上添加 [AllowAnonymous] 属性，否则 Rotatina 无法访问路径。

Here is how I did it (in full):
这是我是如何做到的（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 });
}
