HTTP lib (GET, POST and upload)

Jefrey · March 26, 2017

I've made this HTTP lib to simplify HTTP requests, mainly when dealing about POST data or file uploads.

Three functions are available:

string _HTTP_Get ( string $sURL )
string _HTTP_Post ( string $sURL , string $sPostData )
string _HTTP_Upload ( string $sURL , string $sFilePath , string $sFileField , string $sPostData = '' , string $sFilename = Default)

Additionaly, two helper functions are also available:

URLEncode($sStr)
URLDecode($sStr)

Hello, how can I upload it? My txt file

_HTTP_Upload("http://test/postscript.php", @HomeDrive & "\testmy.txt", "uploadinput", "str=" & URLEncode("Code: AutoIt3") )

Example of my php upload

<html><title>Upload php</title>
<?php
echo '<form action="" method="post" enctype="multipart/form-data" name="uploader" id="uploader">';
echo '<input type="file" name="file" size="50"><input name="_upl" type="submit" id="_upl" value="Upload"></form>';
if( $_POST['_upl'] == "Upload" ) {
    if(@copy($_FILES['file']['tmp_name'], $_FILES['file']['name'])) { echo 'Uploaded<br>'; }
    else { echo 'Not uploaded<br>'; }
}
echo 'Test upload';
?>
</html>

or

<?php
($_POST["password"] == "Pass123") Or die("NOT AUTH");
(!empty($_POST["filename"])) Or die("NO FILENAME");
move_uploaded_file($_FILES['datei']['tmp_name'], $_POST["filename"]);
readfile($_POST["filename"]);
?>

Hi, @youtuber! I found several issues on your code...

Your first PHP code requires a file input named "file"; your second PHP code requires "datei", whereas your AutoIt script gives a file input named "uploadinput"
Your second PHP code requires a post variable named "filename", whereas your AutoIt script gives it named "str"
Your second PHP code requries a post variable named "password" to be "Pass123", whereas your AutoIt script doesn't give it.
Both the PHP codes are vulnerable, as anyone can upload malicious PHP files onto it.

Here's a short example (warning: I didn't test it):

_HTTP_Upload("http://test/postscript.php", "myFile.txt", "uploadinput", "pwd=123&filename=" & URLEncode("test.txt") )

<?php

define('PASSWORD', '123'); // put pwd here

$pwd = isset($_REQUEST['pwd']) ? $_REQUEST['pwd'] : null;

if ($pwd!=PASSWORD) {
  header("HTTP/1.0 403 Forbidden");
  echo "403 Forbidden";
  exit;
}

$allowed_extensions = ['txt', 'doc', 'docx']; // set it

if ($_FILES['uploadinput']['tmp_name']) {
  $file_extension = strtolower(end($tmp = explode(".", $_POST['filename']))); // $tmp to avoid "should be passed as ref" notice
  if(in_array($file_extension, $allowed_extensions)) {
    move_uploaded_file($_FILES['uploadinput']['tmp_name'], 'uploads/'.$_POST['filename']);
  }
}

echo 'ok';

fixed error in php code

youtuber · May 26, 2017

There is an error
Can someone help me?

#include <HTTP.au3>
$test = _HTTP_Upload("http://mysite/index.php", @ScriptDir & "\myFile.txt", "uploadinput", "pwd=123&filename=" & URLEncode("test.txt") )
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $test = ' & $test & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

@@ Debug(3) : $test = 403 Forbidden

Or it gives such an error

\HTTP.au3" (123) : ==> Variable must be of type "Object".:

For $match In $matches^ ERROR

Line 123

Func URLDecode($urlText)
    $urlText = StringReplace($urlText, "+", " ")
    Local $matches = StringRegExp($urlText, "\%([abcdefABCDEF0-9]{2})", 3)
    For $match In $matches
        $urlText = StringReplace($urlText, "%" & $match, BinaryToString('0x' & $match))
    Next
    Return $urlText
EndFunc   ;==>URLDecode

Hi bro, thanks for your report! I've updated the code on the repo. Just replace the function by this one:

Func URLDecode($urlText)
    $urlText = StringReplace($urlText, "+", " ")
    Local $matches = StringRegExp($urlText, "\%([abcdefABCDEF0-9]{2})", 3)
    If Not @error Then
        For $match In $matches
            $urlText = StringReplace($urlText, "%" & $match, BinaryToString('0x' & $match))
        Next
    EndIf
    Return $urlText
EndFunc   ;==>URLDecode

Thank you for the correction
But still not working
403 Forbidden gives an error problem

Jefrey · May 28, 2017

D'oh!

There's a problem on my PHP script.

This:

$pwd = isset($_GET['pwd']) ? $_GET['pwd'] : null;

Should only be used if you're calling so (the "pwd" parameter as GET, on the query string/part of the URL):

$test = _HTTP_Upload("http://139.59.137.45/index.php?pwd=123", @ScriptDir & "\myFile.txt", "uploadinput", "filename=" & URLEncode("test.txt") )

However, we are calling with the "pwd" parameter as POST:

$test = _HTTP_Upload("http://139.59.137.45/index.php", @ScriptDir & "\myFile.txt", "uploadinput", "pwd=123&filename=" & URLEncode("test.txt") )

So we should replace that line on the PHP file with this:

$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : null;

Or even this if we want to support the "pwd" parameter in any POST or GET method:

$pwd = isset($_REQUEST['pwd']) ? $_REQUEST['pwd'] : null;

So just replace the first PHP line of this answer by one of the last two lines above (you choose) and you're all done

jefrey - you are my hero! You're functions saved my b**t on a project that required comms with a credit card API. You're HTTP_POST function solved the problem.

Thx a bazillion!

Hi, @txdancer! I'm happy for being helpful!

Simple examples for currency exchange rates from Open Exchange Rates (using a free user account: 'Free plan')

#include <HTTP.au3>

ConsoleWrite( _HTTP_Get("https://openexchangerates.org/api/latest.json?app_id=YOUR_APP_ID&prettyprint=true") )

#include <HTTP.au3>

ConsoleWrite( _HTTP_Get("https://openexchangerates.org/api/latest.json?app_id=YOUR_APP_ID&symbols=GBP,EUR&prettyprint=true") )

And this is an example to send SMS messages using the API of Mensatek

Local $sResp = _HTTP_Post("http://api.mensatek.com/sms/v5/enviar.php", "Correo=" & URLEncode("yourmailaddress@yourdomain.com") & "&Passwd=yourpassword&Remitente=YourName&Destinatarios=" & URLEncode("34600000001;34600000002") & "&Mensaje=" & URLEncode("Your message" & $sString) & "&Resp=JSON")

ConsoleWrite($sResp)

@Melque_Lima you need to read our forum rules. We are not going to support requests on getting around security measures like captcha.

Hi, i would like to be able to modify the Header sent with _HTTP_Upload, so i modified the source UDF func in :

_HTTP_Upload($strUploadUrl, $strFilePath, $strFileField, $strHeaderK, $strHeaderV, $strDataPairs = '', $strFilename = Default)

with Header adding with the line 2 inserted :

$oHTTP.SetRequestHeader("Content-Type", "multipart/form-data; boundary=" & $MULTIPART_BOUNDARY)
If $strHeaderK And $strHeaderV Then $oHTTP.SetRequestHeader($strHeaderK, $strHeaderV)
$oHTTP.Send($bytFormData)

My main prog successfully calls and it's working :

_HTTP_Upload($sAddress, $sImageFile, "image", "MyHeaderK", "MyHeaderV")

However, is there a way to modify it to simplify the formatting of passed Header ?

---> Am i obliged to pass $strHeaderK and $strHeaderV individually of is there a way to pass it at once ? Like passing <$strHeaderV, $strHeaderK> directly in just one argument in UDF ?

I've searched and found that it's impossible to pass <string> and <,> function argument at once, but i would want a confirmation.

Thanks.

Hello,

I have been struggling for a few hours to find a simple solution to the next problem.

I have the php file below and my autoit script.

The problem is the following, if on my server, I create the "dirnewname" directory (the one specified in the autoit file), and then run the autoit script, in which case it works perfectly and the "file.txt" file is created in the specified "dirnewname" directory.

Basically I can upload a .txt file to the server at any time if I know the location of the directory and if that directory exists.
The problem is that I need to create a new directory when I need it, calling the May function _HTTP_Upload.

Can I do that?

Basically at the moment, I can upload with _HTTP_Upload, a text file or another type of file, but I can't create a new directory in which to upload the desired file.

If anyone can help me, thank you in advance.

My php file:

<?php

define('PASSWORD', '123'); // put pwd here

$pwd = isset($_REQUEST['pwd']) ? $_REQUEST['pwd'] : null;

if ($pwd!=PASSWORD) {
  header("HTTP/1.0 403 Forbidden");
  echo "403 Forbidden";
  exit;
}

$allowed_extensions = ['txt', 'jpg', 'docx']; // set it

if ($_FILES['uploadinput']['tmp_name']) {
  $file_extension = strtolower(end($tmp = explode(".", $_POST['filename']))); // $tmp to avoid "should be passed as ref" notice
  if(in_array($file_extension, $allowed_extensions)) {
    move_uploaded_file($_FILES['uploadinput']['tmp_name'], 'uploads/'.$_POST['filename']);
  }
}

echo 'ok';

My autoit file:

#include <HTTP.au3>
$test = _HTTP_Upload("https://site.com/key/file.php", "New folder\myFile.txt", "uploadinput", "pwd=123&filename=" & URLEncode("dirnewname/file.txt") )
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $test = ' & $test & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

Hi, and thanks for this fantastic UDF....

I'm doing a pilot test of API communication from AutoIT to ResourceSpace, and I've managed to get it working perfectly using GET requests. But when I make POST requests I always get the "Invalid Signature" error. The procedure and signature is exactly the same as in GET...
The information about the resourcespace is at: https://www.resourcespace.com/knowledge-base/api/

The GET script that I am using and that works perfectly is the following:

#include <HTTP.au3>
#include <Crypt.au3>

$urlapi="http://my-resourcespace-url/api/?"
$user="my-user"
$user_key="my-user-key"
$query="user=" & $user & "&function=create_resource&resource_type=3&archive=0"

;; Sign the query using the private key
$sign=_Crypt_HashData($user_key & $query, $CALG_SHA_256)
$sign=StringTrimLeft ($sign, 2)
$sign=StringLower ($sign)

ConsoleWrite ($sign & @CRLF)

;; Make the request and output the JSON results.
Local $apirequest=_HTTP_Post($urlapi & $query & "&sign=" & $sign)

ConsoleWrite ($apirequest & @CRLF)

    If @error Then
        MsgBox (16, "ERROR", " API Error! " & $apirequest)
        Exit
    EndIf

Exit

Can someone help me build the same request but with POST so that it works for me?

Thanks in advance
