Today’s problem dealt with how we view our invoices online. We use an app on the iSeries that creates a PDF and delivers it to a set destination. That destination, in our case is a regular windows server, the files landing in a small site: pdf.mycompany.com.
My initial approach was simple, use the PHP API I have sitting on the iSeries to make a call to the program – passing it the parameters for that specific invoice, await response (which gave me the new created filename) and then redirect to that URL. The method looks something like this:
[HttpGet] public async Task<ActionResult> GetInvoiceAsync(int invoice) { GetInvoice getInvoice = new GetInvoice(); var client = new HttpClient(); string fileName = await getInvoice.LoadPDF(invoice); string url = "http://pdf.mycompany.com/"; url += fileName + ".pdf"; return Redirect(url); }
This worked great… 90% of the time, but the other 10% of the time, I clicked too quickly on an invoice and got forwarded to a 404.
