I need to download a file that I got from a REST search. The URL is like the following:
https://abc.def/geh/servlet/rest/vault?oid=xxx&expr=files.file1
(I needed to edit it due to privacy reasons..)
The file is supposed to be a result of a Nastran computation, it can be viewed by a simple Texteditor. The Extension is .pch, it is relatively large (~21mb)
How can that be implemented in VBA?
First of all - the link does not work. Second of all: there can be 2 approaches depending on the output of the HTTP request.
If the output is file you can use the code below:
Sub DownloadFile(url As String, filePath As String)
Dim WinHttpReq As Object, attempts As Integer
attempts = 3
On Error GoTo TryAgain
TryAgain:
attempts = attempts - 1
Err.Clear
If attempts > 0 Then
Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")
WinHttpReq.Open "GET", url, False
WinHttpReq.send
If WinHttpReq.Status = 200 Then
Set oStream = CreateObject("ADODB.Stream")
oStream.Open
oStream.Type = 1
oStream.Write WinHttpReq.responseBody
oStream.SaveToFile filePath, 2 ' 1 = no overwrite, 2 = overwrite
oStream.Close
End If
End If
End Sub
If the output is a simple text HTML response you can save the output to a file
Function GetXMLHTTPResult(url As String)
Dim XMLHTTP As Object, attempts As Integer
attempts = 3
On Error GoTo TryAgain
TryAgain:
attempts = attempts - 1
Err.Clear
If attempts > 0 Then
Set XMLHTTP = CreateObject("MSXML2.serverXMLHTTP")
XMLHTTP.Open "GET", url, False
XMLHTTP.setRequestHeader "Content-Type", "text/xml"
XMLHTTP.setRequestHeader "Cache-Control", "no-cache"
XMLHTTP.setRequestHeader "Pragma", "no-cache"
XMLHTTP.setRequestHeader "User-Agent", "Mozilla/5.0 (Windows NT 6.1; rv:25.0) Gecko/20100101 Firefox/25.0"
XMLHTTP.send
GetXMLHTTPResult = XMLHTTP.ResponseText
End If
End Function
Sub SaveFile(url)
res = GetXMLHTTPResult(url)
Open "C:\res.txt" For Output As #1
Write #1, res
Close #1
End Sub
