Hi all.


We need to download files (PDFs basically) from an HTTPS server in a recently migrated Windows PB 2017 application. Any clues on how to do this? We have been taking a look at the INET object but seems more suited for classic HTML interaction (form requests).

Any clue or code sample that you can share?


Thanks in advance.

here below a skeleton that you can adapt following what suggested by Renè.




String ls_get_url
String ls_response_text, ls_status_text
long   ll_status_code

OleObject loo_xmlhttp
ls_get_url = "https://localhost/helloworld/filename"

  loo_xmlhttp = CREATE oleobject
  If loo_xmlhttp.ConnectToNewObject("Msxml2.XMLHTTP.4.0") <> 0 Then Return

  // Trust the SSL Certificate 

  loo_xmlhttp.open ("GET",ls_get_url, false)

  //Get response
  ls_status_text = loo_xmlhttp.StatusText
  ll_status_code =  loo_xmlhttp.Status
  if ll_status_code >= 300 then
    MessageBox("HTTP GET Request Failed", ls_response_text)
    ls_response_text = loo_xmlhttp.ResponseText
  end if

catch (RuntimeError rte)
end try

Hi guys.


This was really helpful, thank you all.

It would be great if Appeon could revamp the current INet implementation to support all these stuff natively, something similar in funtionality to .NET's WebRequest would be great.

You may use Microsoft Msxml2.XMLHTTP or Msxml2.ServerXMLHTTP ActiveX. https://msdn.microsoft.com/en-us/library/ms759148(v=vs.85).aspx

You need at least the methods "open" (use synchronous call) and "send". You can then check the property "status" and get the response in the property "responseBody". You may also need the response headers (e.g. method "getAllResponseHeaders") to read additional information like the filename.

SocketTools.com has a suite of Active-X objects that do all types of network connectivity. Once purchased, they're free to distribute with your code. 32 and 64bit versions of the controls are included.

HTTP object can be used in Secure mode to connect and send queries, posts, or retrieve/send files to a remote server. The GetFile method is what you would use to retrieve your file. Help file documents everything you need for each control, method, property, and event. We've been using their tools for 20+ years and they've always worked well.

GetURL can be used to download files but it doesn't support HTTPS.

I have a code example that uses the WinHTTP API functions and it does support HTTPS.
