Here's an example how to upload file using WinHttp.au3. I've added event monitoring to (obvious follows) monitor events.

#AutoIt3Wrapper_AU3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6

#include "WinHttp.au3"

You need WinHttp.au3 1.6.1.6. for that.

Is there anyway to send files without the use of a form?

I am migrating all my TCP code to your WinHTTP functions and I use this UDF with the TCP: #645071

Then use this code to do what I need:

Dim  $data[3]
Dim  $filenames[1]

$CLOCKED_IN_USERNAME = _URLEncode($CLOCKED_IN_USERNAME, 1)
$CLUB_DIR = _URLEncode($CLUB_DIR, 1)
$Error = _URLEncode($Error, 1)
$data[0] = "User="&$CLOCKED_IN_USERNAME
$data[1] = "Club="&$CLUB_DIR
$data[2] = "Error="&$Error

$filenames[0] = $Zip_File

_HTTPPost_files($host, $page, $socket, $data, $filenames)

The other day mikeytown2 posted one post in HTTP UDF's thread that got me thinking if there is better (different) method to send requests through the HTTP protocol to HTTP servers. There is Winhttp.d

Yes thanks. But the only valid warning is with unreferenced parameter inside __WinHttpFormUpload. I'll fix that.

Hey Raizeno, try this: #include "WinHttp.au3" $sAddress = "https://api.pushover.net/1/messages.json" $sApiToken = "av26ac2nAXLyPKg2QMy4zf9YcUjz2G" ; <-yours here $sUserKey = "uMQf396GvMgrsDr

Where do you upload to?

Normally:

http://www.imvu-e.com/api/email_error.php

I have created a test form to test it out, as this method doesnt not require me to use the base64 UDF, so it saves some space. I just didnt really want people to find the form and mess with it, but not a huge deal. I can't get the form to work using your UDF.

If I manually select a zip file it works fine, the HTTP information shows it as Content-Type: application/octet-stream.

When I use your UDF it shows as Content-Type: application/zip

I am not sure if that is causing it not to process correctly or not, but it seems to be the only thing I find different about manually using the form and autoit.

My test URLS for WinHTTP

http://www.imvu-e.com/api/email_error_form.php

http://www.imvu-e.com/api/email_error_http.php

Edit:

Here are the 2 HTTP POSTs side by side.

Your UDF:

The biggest thing that strikes me as odd is the content length.

Edit 2:

I have tested it with forcing application/octet-stream...Still nothing. Also I don't think content length is a big deal because of the different sizes in the Boundary is probably contributing to that.

There was an issue in WinHttp_1.6.1.6.

Funny thing is you found it right away. It took me some thinking on my side yesterday to find it. I have yesterday. It was Revision 58.

Can you try the latest file (rev 60). Link to that.

If that works I will make new release right away.

edit:

The issue is seen in the first line of what you posted as Your UDF. It's:

POST /api/email_error_form.php/email_error_http.php HTTP/1.1
and should be:
POST /api/email_error_http.php HTTP/1.1

With callback? If yes then try without it.

Yes with the callback.

I noticed it happens way more often if I don't close the handles. What I am doing is sending a debug log file to my email when there is an AutoIT error. Basically a second script runs side by side the main script. When it realizes the PID wants to terminate, it reads the console and finds the error, then it takes my temporary debug file in %TEMP% and creates a zip file and posts it to a PHP file that sends it to my email.

The problem I had is that if there is an unexpected error, I didnt account that I should close the handle so what I did was close all WinHTTP handles using OnAutoItExitRegister. This seems to cut down the AutoIt hard crashes ten fold.

Edit:

If I disable the callback, I can't get it to crash even with not closing the handle. It definitely seems the instability of using the callback has to deal with closing handles properly.

I actually expected something like that. I think It's related to lifetime of the callbacks in AutoIt. WinHttp keeps calling function that no longer exists.

This is old AutoIt's issue. It can be worked around by smarter coding (closing handles in this case).

The helpfile isn't working, i only get Page cannot be displayed in it.

Is there somewhere a descent example for using WINhttp with Google as example?

Like why isn't this working?

#include<WinHTTP.au3>


$LocalIP = "www.google.com"
$hw_open = _WinHttpOpen()
$hw_connect = _WinHttpConnect($hw_open, $LocalIP)

$h_openRequest = _WinHttpOpenRequest($hw_connect, "GET", "","","","")
$data = ""

local $SendREQ = _WinHTTPSendRequest($h_openRequest) ; send request
_WinHttpReceiveResponse($h_openRequest) ; wait for response

$sHeaders = _WinHttpQueryHeaders($h_openRequest)


$sData = ""
If _WinHttpQueryDataAvailable($h_openRequest) Then
    Do
        $sData &= _WinHttpReadData($h_openRequest)
    Until @error<>0
EndIf

_WinHttpCloseHandle($h_openRequest)

_WinHttpCloseHandle($hw_connect)

_WinHttpCloseHandle($hw_open)


MsgBox(0, 'Header', $sHeaders)
MsgBox(0, 'Data', $sData)

Hi,

The helpfile is OK. This behaviour is a "feature" of Windows. You have to open the file properties for the chm-file (Contextmenu -> Properties) and click on "Unblock" and then "Apply". If you need more help look here

Edit: You should have a look at the _WinHttpSimple...-functions. Those functions are designed to simplify some parts of a request.

It doesn't say its blocked. Also the "Unblock" button is missing there.

Edit: The AUTOIT helpfile .CHM is working like a charm... so i'm not sure why this aint workin.

Maybe because you are running it from within zip package. Unzip it if yes.

edit: and there is "Home" button available that would allow you to view online help from the help file as well. That works?

What is the path of your chm-file? It won't work with UNC paths, only local diectories are supported. Try to copy it it the same location as your AutoIt help. What happens then?

Hi Trancexx,

I'll move the post here since it seems the right place where I can get your help:

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

#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

$hRequest = _WinHttpOpenRequest($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.

I tried, using Mozilla Live Headers, to catch them logging from Mozilla itself, and I added them to _WinHttpAddRequestHeaders:

_WinHttpAddRequestHeaders($hRequest, 'Cookie: portal_tid=1286813622690-82399; __utma.....')
_WinHttpAddRequestHeaders($hRequest, 'Cookie: chtOpt=0; cid=661578042; __utma=2148334....')

But notihng change.

It seems that once i close the first call it forgets login datas so when I try to go to inner page he can't find it.

How can it be solved?

Thanks in advance,

M.

It's not cookies. They are properties of session handle. To be sure just add something like:

_WinHttpSetOption($hOpen, $WINHTTP_OPTION_DISABLE_FEATURE, $WINHTTP_DISABLE_COOKIES)

Data is always read in a loop. Fix that then ask again.

edit: it's not clear to me if you get to close $hOpen after logging in. Don't, just continue with that handle; pass it to the next request.
