Msxml2.XMLHTTP - ignore certificate errors


Recommended Posts

Hi guys,

Following up on this thread, I want to do the things with Msxml2.XMLHTTP instead of Winhttp.winhttprequest.5.1.

Using this code:

Func SendXmlPostRequest($url, $auth, $xml) ; Make a POST request to Genesis and get the response.
    Global $oHTTP = ObjCreate('Msxml2.XMLHTTP')
    $oHTTP.Open('POST', $url, False)
    $oHTTP.SetRequestHeader('Authorization', 'Basic' & ' ' & $auth)
    $oHTTP.SetRequestHeader('Content-type', 'application/xml')
    $oHTTP.Option(2) = 0x3300
    $oHTTP.Send($xml)
    $responseText = $oHTTP.ResponseText
    $responseStatus = $oHTTP.Status

    If $responseStatus <> 200 Then ; Check the response code from the server.
        MsgBox(0, 'Message', 'Request failed on subimtion with Response Status:' & ' ' & $responseStatus)
        Exit
    EndIf

    $getCodeArr = _StringBetween($responseText, '<code>', '</code>')
    $getCode = $getCodeArr

    If $getCode <> 0 And $getCode <> 200 Then ; Check the response code from the gateway.
        $getTechicalMessageArr = _StringBetween($responseText, '<technical_message>', '</technical_message>')
        $getTechicalMessage = $getTechicalMessageArr
        MsgBox(0, 'Message', 'Request failed with:' & @CRLF & 'Response Code:' & ' ' & $getCodeArr[0] & @CRLF & 'Technical Message:' & ' ' & $getTechicalMessageArr[0])
        Exit
    EndIf

    If $responseStatus = 200 Then
        $getTransType = _StringBetween($responseText, '<transaction_type>', '</transaction_type>')
        If $getTransType[0] = "capture" Then
            $getCaptureUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
        ElseIf $getTransType[0] = "void" Then
            $getVoidUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
        ElseIf $getTransType[0] = "refund" Then
            $getRefundUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
        ElseIf $getTransType[0] = "credit" Then
            $getCreditUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
        ElseIf $getTransType[0] = "recurring_sale" Then
            $getRecurringSaleUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
        Else
            $getUniqueID = _StringBetween($responseText, '<unique_id>', '</unique_id>')
            $uniqueID = $getUniqueID[0]
        EndIf
    EndIf
EndFunc   ;==>SendXmlPostRequest

Func MyErrFunc()
  Msgbox(0,"AutoItCOM Test","We intercepted a COM Error !"    & @CRLF  & @CRLF & _
             "err.description is: " & @TAB & $oMyError.description  & @CRLF & _
             "err.windescription:"   & @TAB & $oMyError.windescription & @CRLF & _
             "err.number is: "       & @TAB & hex($oMyError.number,8)  & @CRLF & _
             "err.lastdllerror is: "   & @TAB & $oMyError.lastdllerror   & @CRLF & _
             "err.scriptline is: "   & @TAB & $oMyError.scriptline   & @CRLF & _
             "err.source is: "       & @TAB & $oMyError.source       & @CRLF & _
             "err.helpfile is: "       & @TAB & $oMyError.helpfile     & @CRLF & _
             "err.helpcontext is: " & @TAB & $oMyError.helpcontext _
            )
Endfunc

I get an error:

Description: Unknown name.
Number: 80020006
Line: $oHTTP.Option(2) = 0x3300

And then I receive the following:

Description: The download of the specified resource has failed.
Number: 80020009
Source: msxml3.dll
Line: $oHTTP.Send($xml)
Request failed on submission with Response Status: 12004

If I try to use $oHTTP.SetOption(2) = 0x3300 instead of  $oHTTP.Option(2) = 0x3300, I get the following:

Description: Member not found.
Number: 80020003
Line: $oHTTP.SetOption(2) = 0x3300

If I use $oHTTP.SetOption(2, 0x3300), I get the member not found error again.

Could you please point me out here?

Thanks in advance!

The SetOption() method is not a member of the Msxml2.XMLHTTP object.  You want to use the Msxml2.ServerXMLHTTP object.  The Msxml2.ServerXMLHTTP object is very similar to the Msxml2.XMLHTTP as you can see below.  I modified your code to use the Msxml2.ServerXMLHTTP object below.  Of course I can't test it.  Hopefully I didn't make any typos.  I only modified 3 lines (ObjCreate(), Open(), SetOption() ".  I also added the constants for the SetOption() method and the values for ignoring SSL errors in case you prefer to use named values instead of magic numbers.

Corrected a typo on the Open() line and SetOption()
