Help for Cookies after login

[marko001]

Hi,

I developed a tool to automatically log into a web page:

expandcollapse popup

#include "WinHttp.au3"
#Include <String.au3>
#include <Array.au3>

Opt("MustDeclareVars", 1)

Global $sFile = @DesktopDir & "\Skills.xml"
Global $sFile2 = @DesktopDir & "\Skills2.xml"
Global $hFile, $hfile2
Global $temp_file, $A_token, $P_token

global $p_csrfToken, $p_id



Global $hConnect, $sRead, $hrequest
Global $sContent = "Content-Type: application/x-www-form-urlencoded; charset=UTF-8"
global $sAddress = "mydomain.com"
global $spage = "login"
global $spage_2= "2ndpage?p_id="
Global $hOpen
global $sChunk, $sData


$hOpen = _WinHttpOpen()
$hConnect = _WinHttpConnect($hOpen, $sAddress)
_WinHttpSetOption($hOpen, $WINHTTP_OPTION_USER_AGENT, $sContent)
$sRead = _WinHttpSimpleFormFill($hConnect, $spage ,"logindata","name", "myname", "password", "mypw")

If @error Then
    msgbox(0,"","Error")
    Exit
Else
    $hFile = FileOpen($sFile, 2)
    FileWrite($hFile, $sRead)
    FileClose($hFile)
EndIf

Into this page i can find a unique ID I need to go further:

FileOpen($sfile)
$temp_file = FileRead($sfile)
$P_token = _StringBetween($temp_file,"p._id = '","';",-1)
$p_id = _ArrayToString($P_token)
fileclose($sfile)
$spage_2= $spage_2& $p_id

Now i need to go further, second page, using the url:

http://mydomain.com/2ndpage?p_id=$p_id (the one i got into previous lines)

I tried

expandcollapse popup

$hRequest = _WinHttpOpenRequest($hConnect, _
        "GET", _ ; verb
        $spage_2=, _    ; target
        Default, _ ; version
        $sAddress, _    ; referer
        "*/*") ; accept

_WinHttpAddRequestHeaders($hRequest, "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3")
_WinHttpAddRequestHeaders($hRequest, "Accept-Language: it-it,it;q=0.8,en-us;q=0.5,en;q=0.3")
_WinHttpAddRequestHeaders($hRequest, "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
_WinHttpAddRequestHeaders($hRequest, "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7")
_WinHttpAddRequestHeaders($hRequest, "Keep-Alive: 115")
_WinHttpAddRequestHeaders($hRequest, "Connection: keep-alive")
_WinHttpAddRequestHeaders($hRequest, "Accept: application/json, text/javascript, */*")
_WinHttpAddRequestHeaders($hRequest, "Content-Type: application/x-www-form-urlencoded; charset=UTF-8")
_WinHttpAddRequestHeaders($hRequest, "Cache-Control: no-cache")

global $answer = _WinHttpSendRequest($hRequest)

;msgbox(0,"answer",$answer)

global $answer2 = _WinHttpReceiveResponse($hrequest)
If @error Then
    MsgBox(48, "Error", "Error ocurred for WinHttpReceiveResponse, Error number is " & @error)
Else

EndIf

global $data_avail = _WinHttpQueryDataAvailable($hRequest)
;msgbox(0,"data",$data_avail)

If _WinHttpQueryDataAvailable($hRequest) Then
    ; Read
    $hFile2 = FileOpen($sFile2, 2)
    FileWrite($hFile2, _WinHttpReadData($hRequest))
    FileClose($hFile2)
Else
    MsgBox(48, "Error", "Site is experiencing problems.")
EndIf

I always get no errors into msgboxes but always a 0 bytes file.

I think problem is due to cookies, since it seems he can't remember previous credentials.

How can it be solved?

Thanks in advance,

M.
