Question

我试图通过产生以超文本为基础的国防军来制造“报告”。

首先,我只是试图用 raw字书写硬形的超文本,然后用 Java印该文件。然而,这给我带来了对头脑和脚.的控制。

我尝试使用<代码>thead和tfoot内容,这些内容在大多数浏览器中相当有效,但我无法得到我所期待的格式。

目前,我正试图在MVC3使用iTextSharp进行服务器边解决方案,然而,我对于如何继续工作,没有与iTextSharp做很多工作,就失去了一点。

编写报告时将使用4个项目:

Report Content (which is currently encoded HTML, as I am unsure if decoding will change any formatting)
Report Title (will simply be the name of the PDF generated)
Report Header (will be displayed at the upper-left of each page)
Report Footer (will be displayed at the lower-left of each page)

www.un.org/Depts/DGACM/index_spanish.htm 主计长行动:

//This will be accessed by a jQuery Post
[HttpPost]
public FileStreamResult GeneratePDF(string id)
{
      //Grab Report Item
      ReportClass report = reportingAgent.GetReportById(id);

      Document doc = new Document();

      //Do I need to decode the HTML or is it possible to use the encoded HTML?

      //Adding Headers / Footers

      //Best method of returning the PDF?
}

Answer 1

iTextSharp cannot convert HTML to PDF. It s not what it was designed to do. It was designed to create PDF files from scratch, not converting between various formats into PDF. If you want to convert HTML into PDF you could for example use the the flying-saucer library which is based on iText. I have blogged about how this could be done in .NET using IKVM.NET Bytecode Compiler (ikvmc.exe).

因此,你的控制者的行动可能会看一看:

[HttpPost]
public FileStreamResult GeneratePDF(string id)
{
    ReportClass report = reportingAgent.GetReportById(id);
    return PdfResult(report.Html);
}

public class PdfResult : ActionResult
{
    private readonly string _html;
    public PdfResult(string html)
    {
        _html = html;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        var response = context.HttpContext.Response;
        response.ContentType = "application/pdf";
        var builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        using (var bais = new ByteArrayInputStream(Encoding.UTF8.GetBytes(_html)))
        using (var bao = new ByteArrayOutputStream())
        {
            var doc = builder.parse(bais);
            var renderer = new ITextRenderer();
            renderer.setDocument(doc, null);
            renderer.layout();
            renderer.createPDF(bao);
            var buffer = bao.toByteArray();
            response.OutputStream.Write(buffer, 0, buffer.Length);
        }
    }
}
