以编程方式生成报告

有关如何以编程方式将报告生成为PDF文件并显示SaveFileDialog以下载/保存生成的PDF的示例,请参阅下面的代码段:

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);
        }
    });
}

如果不想公开URL,可接受的方法似乎是调用一个方法将文件存储到Acumatica记录,然后通过API检索文件: Get report output in PDF fromat via Acumatica REST API

由于我使用的是REST API,并且由于某种原因,PXRedirectToFileException确实可以在那里工作(它不返回位置头),所以我对接受的答案有问题。我想出了一个非常笨拙的解决方案,导致文件URL在异常中公开。

  {

    #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 FileUrlException(url);
     }

    #endregion

    }

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

        }
    }

}

缺点是此操作只能通过API使用。 我将该操作添加到web服务端点。在另一端,我使用regex从异常消息中提取字符串,并执行get请求来获取文件。
