_WinHttpSetOption($h_openRequest, $WINHTTP_OPTION_DISABLE_FEATURE, $WINHTTP_DISABLE_REDIRECTS)

That's it >_<

Thank you.

Hi :)

Very nice script!

One question though:

When there's more than one response header with the same name, how do I get the second?

This returns only the first cookie in "Set-Cookie" return header:

$cookieResp = _WinHttpQueryHeaders($h_openRequest, $WINHTTP_QUERY_SET_COOKIE)

The case is that I have a server returning 2 cookies and I need them both. Am trying to avoid parsing the full header. Was hoping the _WinHttpQueryHeaders could do it.

Thanks!

No, just one. You have to read it all if you want more.

Thank you trancexx.

So this is not related to what I'm trying to achieve?

http://msdn.microsoft.com/en-us/library/aa384102(VS.85).aspx

Quoting from that page: "lpdwIndex [in, out] - Pointer to a zero-based header index used to enumerate multiple headers with the same name."

Thanks :)

Yes that's it. In WinHTTP.au3 WINHTTP_NO_HEADER_INDEX is used for that parameter.

I didn't thought it would be needed to have it changable. My thinking was - why call function five (e.g.) times to get all cookies (e.g. again) when you can regexp it from the full header.

But I guess you could have need to target the second one.

In any case it was me that set the limit. Maybe I shouldn't have.

It's no biggie. The reason why I asked is because I don't know enough AutoIT to modify your _WinHttpQueryHeaders so that it returns multiple values of cookies (msdn page is enough but not for me :) )

Parsing the full string (delimited with CRLF) is causing me codepage issues because, for ex, _ArrayFindAll (after StringSplit) is not finding the string "Set-Cookie" (I just tested and, for ex, my "S", is not the same as the "S" that I'm getting returned).

Is it complicated to adapt your function?

RegExp is also not my forté..

Thanks in advance

Try this:

#include <Array.au3>

$aCookies = StringRegExp($sFullHeader, "Set-Cookie: (.*?)" & @CRLF, 3)

_ArrayDisplay($aCookies)

Awesome. thanks again trancexx.

Look what I was doing (rookie style):

$headersArray = StringSplit($headers, @CRLF, 1)

For $ha = 1 To UBound($headersarray)-1

If stringleft($headersarray[$ha],20) = "Set-Cookie: .EMCAUTH" Then

$Cookie1 = StringMid($headersarray[$ha], 5)

ElseIf stringleft($headersarray[$ha],29) = "Set-Cookie: ASP.NET_SessionId" Then

$Cookie2 = StringMid($headersarray[$ha], 5)

EndIf

Next

        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

this is supposed to download an XML documents contents off the API server for EVE-online. I am only recieveing mayby a 1/20th of the file can someone help me to be able to get the whole file?

Hello,

I want get cookies returned by a web page.

This web page should return a code 302 (moved temporarly) but I get a 200 code when I use _WinHttpQueryHeaders.

When I look in wireshark (network protocol analyzer) I see the code 302 first followed by 200.

How to get the first header ?

Thx

I found the answer : _WinHttpSetOption($h_openRequest,$WINHTTP_OPTION_DISABLE_FEATURE,$WINHTTP_DISABLE_REDIRECTS)

Uh, yes, it's not a support forum.

But I'll post my question here hoping someone can give me a helping hand.

The tcp-solution gives me more info then the one using winhttp.

What parameters should I set to get these?

It seems im blindfolded.

Edit: Uh, the 302 output is a redirect, so I need to enable that...

Maybe you can tell me how I should adjust the call. ;)

So, here is the code:

    Local $BytesSent = TCPSend($Socket, $Command)
    If $BytesSent = 0 Then Return SetError(1, @error, 0)
    Return $BytesSent
EndFunc   ;==>__HTTPGet

Func __HTTPGetResponse($Host, $Page, $sRequest = "GET", $sReferrer = "")
    Local $Socket = __HTTPConnect($Host)

    __HTTPGet($Host, $Page, $Socket, $sRequest, $sReferrer)

Hello Guys

Some 1 plz explane me why i am not getting the result with POST method?

php

<?php
$nver = 101;
$rver =  $_POST['v'];
$cver = (int)$rver;

if ($rver == ""){
    echo "Nothing Found";
}else if($nver == $cver){
    echo "same ver";
}else if($nver > $cver){
    echo "new ver: " . $nver;
}
?>

Au Code

#include "WinHTTP.au3"

$hOpen = _WinHttpOpen()

$hConnect = _WinHttpConnect($hOpen, "www.example.com")

$hRequest = _WinHttpOpenRequest($hConnect, "POST", "ver/123.php")

$data = "v=101"

_WinHttpSendRequest($hRequest,$WINHTTP_NO_ADDITIONAL_HEADERS, $WINHTTP_NO_REQUEST_DATA, StringLen($data))

_WinHttpWriteData($hRequest, $data)

_WinHttpReceiveResponse($hRequest)

If _WinHttpQueryDataAvailable($hRequest) Then
;~  $header = _WinHttpQueryHeaders($hRequest)
;~  MsgBox(0, "Header", $header)

    MsgBox(0,"RCVD",_WinHttpReadData($hRequest))
EndIf

_WinHttpCloseHandle($hRequest)

_WinHttpCloseHandle($hConnect)

_WinHttpCloseHandle($hOpen)

After execution its always return "Nothing Found" with POST method; & with GET method its return "same ver"
