WinHTTP functions

jackchen · June 25, 2015

Ah yes, option to list all was added with win8. On your system it's not possible to list all entries using underlying function. Did you search around the web to see how to do it on pre-win8 systems?

I found this topic https://groups.google.com/forum/#!topic/microsoft.public.security.crypto/WHwxS2vG_0E point out the way:

Subject Alternative Names (SAN) are certificate extensions. Programmatically 
you can get to them by accessing rgExtension member of the 
pCertInfo(CERT_INFO) member of the CERT_CONTEXT structure. Use 
CertFindExtension() to find an extension  by oid = szOID_SUBJECT_ALT_NAME2. 
To format the encoded string into WCHAR string use CryptFormatObject().

And this: http://swift.im/git/swift/plain/Swiften/TLS/Schannel/SchannelCertificate.cpp , some c codes to parse SSL certificate,but I have no knowledge of c language,it puzzles me.

So I'm trying to make a script to upload images to Imgur. I'd like to use the latest version of the API because that's all I can get keys for. I found the following VB code: http://pc-tips.net/imgur-api-vb-net/ which I have converted as much as possible to AutoIt:

UploadImage(FileOpenDialog("Open", @ScriptDir, "Images (*.jpg;*.gif;*.png;*.bmp)", $FD_FILEMUSTEXIST))

Func UploadImage($image)
    ; I assume WinHttp can be used in place of the following?   
    Local $w As WebClient()

    $w.Headers.Add("Authorization", "Client-ID Put your client id here")

    Local $base64_image = _Base64Encode($image)

    Local $responseArray = $w.UploadValues("https://api.imgur.com/3/image", $base64_image)
    
    ; I'll look into the regex matching when I can see the actual response
    Local $result = Encoding.ASCII.GetString($responseArray)

    Local $reg = System.Text.RegularExpressions.Regex("link"":""(.*?)""")

    Local $match = $reg.Match($result)

    Local $url = $match.ToString.Replace("link"":""", "").Replace("""", "").Replace("\/", "/")

    Return $url
EndFunc

; Author: Ward
Func _Base64Encode($Data, $LineBreak = 76)
    Local $Opcode = "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

    Return DllStructGetData($Ouput, 1)
EndFunc

My question is do I need to use WinHttp.au3 to take the place of WebClient and UploadValues? The Imgur documentation says to post a Base64 encoded image to this address: https://api.imgur.com/3/image

Method	POST
Route	https://api.imgur.com/3/image
Alternative Route	https://api.imgur.com/3/upload
Response Model	Basic

Parameters

Key	Required	Description
image	required	A binary file, base64 data, or a URL for an image. (up to 10MB)
album	optional	The id of the album you want to add the image to. For anonymous albums, {album} should be the deletehash that is returned at creation.
type	optional	The type of the file that's being sent; file, base64 or URL
name	optional	The name of the file, this is automatically detected if uploading a file with a POST and multipart / form-data
title	optional	The title of the image.
description	optional	The description of the image.

Any help that you can provide will be appreciated.

Ok, I think I'm starting to put together some sort of picture here.

$w.Headers.Add("Authorization", "Client-ID Put your client id here")

is:

_WinHttpAddRequestHeaders("Authorization", "Client-ID Put your client id here")

and this:

Local $responseArray = $w.UploadValues("https://api.imgur.com/3/image", $base64_image)

is:

_WinHttpSendRequest("https://api.imgur.com/3/image", $base64_image)

Along with any required startup procedures?

trancexx · July 20, 2015

Probably.

This could also work (maybe):

#include "WinHttp.au3"

Const $sClientID = "3fda9b4a8bc150c" ; your client-id
Const $sAddress = "https://api.imgur.com/3/upload.xml" ; the address of the target (https or http, makes no difference - handled automatically)
Const $sForm = _
        '<form action="' & $sAddress & '" method="post" enctype="multipart/form-data">' & _
        ' <input type="file" name="image"/>' & _ ;
        '</form>'

$sFileToUpload = FileOpenDialog("Open", @ScriptDir, "Images (*.jpg;*.gif;*.png;*.bmp)")

; Initialize and get session handle
$hOpen = _WinHttpOpen()

$hConnect = $sForm ; will pass form as string so this is for coding correctness because $hConnect goes in byref



; Fill form
$sReturned = _WinHttpSimpleFormFill($hConnect, $hOpen, _
        Default, _
        "name:image", $sFileToUpload, _
        "Authorization: Client-ID " & $sClientID)

If @error Then
    MsgBox(4096, "Error", "Error number = " & @error)
Else
    ConsoleWrite($sReturned & @CRLF)
EndIf



; Close handles
_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)

Awesome! It works thanks to your superior interlect. Thank you.

There is one small problem though. It fails with error 4 on a 2mb image. Imgur can accept up to 10mb so I don't know where the issue lies. I was hoping you might know.

Is it an animated gif ?

Because Imgur limit animated gif to 2mb.

i have resized your picture and get a 5.43MB file who was slowly but succesfully uploaded with TinyPicSharer.

But i do not use the _WinHttpSimpleFormFill function.

Look at the source.

jaberwacky · July 20, 2015

I have surgically examined your source. Combed through it with a fine comb. I finally came to the realization that your code uses version 2 of the Imgur API for which I can no longer receive a key.

Maybe you need to verify your account to get that sizes. I don't know, sorry.

Forget my suggestion.

I just realize that my compiled version works, but not the script under 3.3.14.0 !

i must investigate the problem.

Edit : works under 3.3.12.0

My outerlect was also useful this time. I know what's the problem. Imgur internally processes your file after the upload (validates, converts to whatever format) and this takes time. After they process the file they make a response. It appears for bigger files they need more than default 30 seconds that WinHTTP waits for server to reply. You can confirm this by yourself by changing/adding line to WinHttp.au3.
So, if you want, find function __WinHttpFormSend() and add:

_WinHttpSetTimeouts($hRequest, Default, Default, Default, 100000)

...line just before:

_WinHttpSendRequest($hRequest, Default, $sAddData)

If you have slow internet add it like this:

WinHttpSetTimeouts($hRequest, Default, Default, 100000, 100000)

That will make WinHttp.au3 wait up to 100 seconds before returning.

jaberwacky · July 21, 2015

This is a good day for the internet.

It works! Thank you once again.

jaberwacky · July 21, 2015

Look at the source.

So I've been trying to see if I can make a version 3 function based on your function _HostImGurUpload and being informed by trancexx's code that she so graciously provided I get this:

This function seems to connect to the the Imgur server but I get this as an error message:

<?xml version="1.0" encoding="utf-8"?>
<data type="array" success="0" status="400"><error>HTTP Access is disabled. Requests must use SSL (HTTPS).</error><request>/3/upload.xml</request><method>POST</method></data>

Can anyone make out what this means and how to fix it please? I tried using "https://api.imgur.com" in the _WinHttpConnect function but no joy.

Edit: might it have to do with this: _WinHttpOpenRequest($hConnect, "POST", "/3/upload.xml", "HTTP/1.1") <-- I wouldn't know what to change HTTP/1.1 to.

Edit2: Well, I see a few more issues that I will need to sort out before this will work such as where to put the client id et cetera.

I think I have the HTTPS stuff figured out. Now it's on to providing my client id to Imgur.

If you use https then you have to use _WinHttpSendSSLRequest instead of _WinHttpSendRequest. Notice the SSL part.

I could help you with the rest but I don't want to take that "Made it Ma! Top of the world!" feeling away from you.

I assume that's _WinHttpSimpleSendSSLRequest?

Is that a hint that I'm on the right trajectory?
