Question

假设我使用Acumatica报告设计器创建了一个报告，它与相关的DAC相关联。

我还有一个带有Action的自定义屏幕。当用户执行此操作时，我想生成报告，以便用户将其下载为pdf。

通过Acumatica API以编程方式生成报告的方法是什么？

Answer 1

请参阅下面的代码片段，了解如何以编程方式生成报告为PDF文件并显示SaveFileDialog以下载/保存生成的PDF：

public PXAction<IOITInboundTestWorkOrder> GenerateReportAndRedirectToFile;
[PXButton]
[PXUIField(DisplayName = "Generate Report and Download as PDF")]
protected void generateReportAndSaveToDB()
{
    Actions.PressSave();
    PXLongOperation.StartOperation(this, () =>
    {
        PX.SM.FileInfo file = null;
        using (Report report = PXReportTools.LoadReport("SO641012", null))
        {
            var orderNbr = ITWO.Current.OrderNbr;
            if (report == null) throw new Exception("Unable to access Acumatica report writter for specified report : " + "SO641012");
            Dictionary<string, string> prams = new Dictionary<string, string>();
            prams["ITWONbr"] = orderNbr;
            PXReportTools.InitReportParameters(report, prams, PXSettingProvider.Instance.Default);
            ReportNode repNode = ReportProcessor.ProcessReport(report);
            IRenderFilter renderFilter = ReportProcessor.GetRenderer(ReportProcessor.FilterPdf);

            using (StreamManager streamMgr = new StreamManager())
            {
                renderFilter.Render(repNode, null, streamMgr);
                string fileName = string.Format("Inbound Test Work Order #{0}.pdf", orderNbr);
                file = new PX.SM.FileInfo(fileName, null, streamMgr.MainStream.GetBytes());
            }
        }
        if (file != null)
        {
            throw new PXRedirectToFileException(file, true);
        }
    });
}

如果您不想处理公开URL，则可接受的方法似乎是调用一种方法将文件存储到Acumatica记录，然后通过API Get report output in PDF fromat via Acumatica REST API

Answer 3

由于我使用的是REST API，并且由于某种原因PXRedirectToFileException确实可以在这里工作（它不返回位置标头），因此我在接受答案时遇到了麻烦。我想出了一个非常笨拙的解决方案，它避免了在异常情况下公开文件URL。原谅我粗鲁的异常名称。：-）

using SiteStatus = PX.Objects.IN.Overrides.INDocumentRelease.SiteStatus;
using System.Linq;
using PX.Common;
using CRLocation = PX.Objects.CR.Standalone.Location;
using PX.Objects.AR.CCPaymentProcessing;
using PX.Objects.AR.CCPaymentProcessing.Common;
using PX.Objects.AR.CCPaymentProcessing.Helpers;
using PX.Objects.Common;
using PX.Objects;
using PX.Objects.SO;
using PX.Reports;
using PX.Reports.Data;
using PX.Data.Reports;
using PX.SM;

namespace PX.Objects.SO
{

  public class SOInvoiceEntry_Extension:PXGraphExtension<SOInvoiceEntry>
  {

    #region Event Handlers
    protected virtual void ARInvoice_RowSelected(PXCache cache, PXRowSelectedEventArgs e){
        CreateInvoicePDF.SetEnabled(true);
    }

     public PXAction<ARInvoice> CreateInvoicePDF;
     [PXButton]
     [PXUIField(DisplayName = "Create Invoice PDF", Enabled = true, Visible = false)]
     public virtual void createInvoicePDF()
     {
            //Report Paramenters
            Dictionary<String, String> parameters = new Dictionary<String, String>();
            parameters["DocType"] = Base.Document.Current.DocType;
            parameters["RefNbr"] = Base.Document.Current.RefNbr;

            //Report Processing
            PX.Reports.Controls.Report _report = PXReportTools.LoadReport("SO643000",null);
            PXReportTools.InitReportParameters(_report, parameters, SettingsProvider.Instance.Default);
            ReportNode reportNode = ReportProcessor.ProcessReport(_report);

            // Generate PDF
            byte[] data = PX.Reports.Mail.Message.GenerateReport(reportNode, ReportProcessor.FilterPdf).First();
            FileInfo file = new FileInfo(Guid.NewGuid(), "Invoice" + Base.Document.Current.RefNbr + ".pdf", null, data);

            // Store data in session
            PXContext.SessionTyped<PXSessionStatePXData>().FileInfo[file.UID.ToString()] = file;

            // Include file URL in exception. The client will parse the filname and fetch the URL in a subsequent request.
            PXRedirectToFileException e =  new PXRedirectToFileException(file.UID, 0, true, true);

            string url = e.Url;

            throw new AcumaticaIsFullOfShitException(url);
     }

    #endregion

    }

    class AcumaticaIsFullOfShitException : PXException {
        public AcumaticaIsFullOfShitException(string message) : base(message) {

        }
    }

}

缺点是只能通过API使用此操作。我将操作添加到了Web服务端点。另一方面，我使用正则表达式从异常消息中提取字符串，并执行了获取请求以获取文件。
