WinHttp.WinHttpRequest.5.1 - POST binary file

[Total_newbie]

Hi all,

I'm trying to post a binary file using WinHttp.WinHttpRequest.5.1 and the POST method.

CODE

$sUrl = "http://192.168.0.1/cgi-bin/upload_file.cgi"

$PostData="executable.exe"

ConsoleWrite($PostData)

$oHttpRequest = ObjCreate("WinHttp.WinHttpRequest.5.1")

$oHttpRequest.Open ("POST", $sUrl, False)

$oHttpRequest.setRequestHeader("Connection", "Keep-Alive")

$oHttpRequest.setRequestHeader("Referer", "http://192.168.0.1/cgi-bin/upload_file.cgi")

$oHttpRequest.Send ($PostData)

Since it's not working, I sniffed the traffic and got the following message by the time I was uploading the file. Can anybody point me to the documentation where I can see what this boundary variable should contain?

HTTP Protocol

- The multipart dissector could not find the required boundary parameter

Thanks

Looks like the error might be similar to this: WireShark Wiki: MIME multipart (mime_multipart)

That looks like a setting in WireShark to know how to break down the MIME packets. Specifically, how to know what delimits the parts of the MIME block of data.

Not sure, but you might try changing this line:

$PostData=FileRead("executable.exe")

Here is the documentation for the WinHTTP Request object:

You're missing the 'Content-Type' RequestHeader that tells the server how to parse what you are posting...

Hi Dale, you are right. I added the following line $oHttpRequest.setRequestHeader ("Content-Type", "multipart/form-data") and now it's complaining about the boundary parameter which should look like this ";boundary=---------------------------7d71f2d701e2". Based on some documentation that I read this information is generated automatically as well as the "Content-Lenght" parameter. Now I'm trying to find out how do I generate and pass that to my script. Any clue?

Hi Dale, I decide to play a little bit with IE.au3 and was trying the example 5 of the help. However I cannot submit the form after insertig the filename in the form. Any clue?

CODE

#include <IE.au3>

$oIE = _IECreate ("http://10.0.0.108/cgi-bin/upload_form.cgi")

$oForm = _IEFormGetCollection ($oIE, 0)

$oInputFile = _IEFormElementGetObjByName ($oForm, "x_filename")

_IEAction($oInputFile, "focus")

$hIE = _IEPropertyGet($oIE, "hwnd")

ControlSend($hIE, "", "Internet Explorer_Server1", "example.au3")

$osubmit = _IEFormElementGetObjByName ($oForm, "Submit")

_IEAction($osubmit, "click")

_IEAction($oIE, "visible")

Hopefully you are running this with Tools -> Go in SciTe... do you get any messages in the console?
