我可以通过API删除Acumatica中的文件吗?

找到了如何从Acumatica中删除文件以及如何保存现有文件的新版本的示例!下面的实现保存了一个新版本,但删除方法已被注释掉。因为我将其构建到了报表生成过程中,所以我以后不会通过API删除报表,但很容易将删除转换为API可调用的操作。

private IEnumerable ExportReport(PXAdapter adapter, string reportID, Dictionary<String, String> parameters)
    {
        //Press save if the SO is not completed 
        if (Base.Document.Current.Completed == false)
        {
            Base.Save.Press();
        }

        PX.SM.FileInfo file = null;
        using (Report report = PXReportTools.LoadReport(reportID, null))
        {
            if (report == null)
            {
                throw new Exception("Unable to access Acumatica report writer for specified report : " + reportID);
            }

            PXReportTools.InitReportParameters(report, parameters, PXSettingProvider.Instance.Default);
            ReportNode reportNode = ReportProcessor.ProcessReport(report);
            IRenderFilter renderFilter = ReportProcessor.GetRenderer(ReportProcessor.FilterPdf);

            //Generate the PDF
            byte[] data = PX.Reports.Mail.Message.GenerateReport(reportNode, ReportProcessor.FilterPdf).First();
            file = new PX.SM.FileInfo(reportNode.ExportFileName + ".pdf", null, data);

            //Save the PDF to the SO
            UploadFileMaintenance graph = new UploadFileMaintenance();

            //Check to see if a file with this name already exists                
            Guid[] files = PXNoteAttribute.GetFileNotes(Base.Document.Cache, Base.Document.Current);
            foreach (Guid fileID in files)
            {
                FileInfo existingFile = graph.GetFileWithNoData(fileID);
                if (existingFile.Name == reportNode.ExportFileName + ".pdf")
                {
                    //If we later decide we want to delete previous versions instead of saving them, this can be changed to 
                    //UploadFileMaintenance.DeleteFile(existingFile.UID);
                    //But in the meantime, for history purposes, set the UID of the new file to that of the existing file so we can save it as a new version.
                    file.UID = existingFile.UID;
                }
            }

            //Save the file with the setting to create a new version if one already exists based on the UID                          
            graph.SaveFile(file, FileExistsAction.CreateVersion);  
            //Save the note attribute so we can find it again.              
            PXNoteAttribute.AttachFile(Base.Document.Cache, Base.Document.Current, file);
        }

        //Return the info on the file
        return adapter.Get();
    }

Acumatica的反应是: S-b(屏幕基础)API允许以干净的方式下载生成为文件的报告。C-b(合同基础)根本没有添加此功能。我建议您在这里提供反馈:feedback.acumatica.com(编辑:Done! https://feedback.acumatica.com/ideas/ACU-I-1852

我认为有两种解决方法: 1) 使用从c-b登录的s-b生成报告并获取为文件(参见下面的示例),或者

#1的示例

        using (DefaultSoapClient sc = new DefaultSoapClient("DefaultSoap1"))
        {
            string sharedCookie;
            using (new OperationContextScope(sc.InnerChannel))
            {
                sc.Login("admin", "123", "Company", null, null);
                var responseMessageProperty = (HttpResponseMessageProperty)
                OperationContext.Current.IncomingMessageProperties[HttpResponseMessageProperty.Name];
                sharedCookie = responseMessageProperty.Headers.Get("Set-Cookie");
            }

            try
            {
                Screen scr = new Screen();  // add reference to report e.g. http://localhost/Demo2018R2/Soap/SO641010.asmx
                scr.CookieContainer = new System.Net.CookieContainer();
                scr.CookieContainer.SetCookies(new Uri(scr.Url), sharedCookie);

                var schema = scr.GetSchema();
                var commands = new Command[]
                {
                    new Value { LinkedCommand = schema.Parameters.OrderType, Value = "SO" },
                    new Value { LinkedCommand = schema.Parameters.OrderNumber, Value = "SO004425" },
                    schema.ReportResults.PdfContent
                };

                var data = scr.Submit(commands);
                if(data != null && data.Length > 0)
                {
                    System.IO.File.WriteAllBytes(@"c:\Temp\SalesOrder.pdf", 
                        Convert.FromBase64String(data[0].ReportResults.PdfContent.Value));
                }
            }
            finally
            {
                sc.Logout();
            }
        }
