Curl command in php to post LUA commands

[Julio César Luciano da Silva]

Hi, I'm trying to play a POST command to a lua script, but I get a "bool(false)" response on my system, any help on what's wrong?

$ curl -X POST http://localhost:8042/tools/execute-script --data-binary @script.lua

<?php

$orthanc = "http://localhsot:8042/";

$url = $orthanc.'/tools/execute-script';

$uploadFilePath = __DIR__ . '/script.lua';

//$uploadFilePath="@$file[tmp_name]";

if (!file_exists($uploadFilePath)) {

    throw new Exception('File not found: ' . $uploadFilePath);

}

$uploadFileMimeType = mime_content_type($uploadFilePath);

$uploadFilePostKey = 'file';

$uploadFile = new CURLFile(

    $uploadFilePath,

    $uploadFileMimeType,

    $uploadFilePostKey

);

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [

    CURLOPT_URL => $url,

    CURLOPT_RETURNTRANSFER => true,

    /**

     * Specify POST method

     */

    CURLOPT_POST => true,

    /**

     * Specify array of form fields

     */

    CURLOPT_POSTFIELDS => [

        $uploadFilePostKey => $uploadFile,

    ],

]);

$response = curl_exec($curlHandler);

curl_close($curlHandler);

echo($response);

Hello,

You should *not* use "CURLFile()" as the argument to "CURLOPT_POSTFIELDS".

Instead, the "CURLOPT_POSTFIELDS" must simply contain a plain string containing your Lua script. For instance:

Also, make sure that the configuration option "ExecuteLuaEnabled" of Orthanc is set to "true":

Thanks Sebastian , I've changed my code to the following structure: although it's not clear to me if it's really pure script injection, or if I have to have a file, my system still doesn't work.

This has been confirmed: "ExecuteLuaEnabled" of Orthanc is set to "true"

<?php

$orthanc = "http://localhsot:8042/";

$url = $orthanc.'tools/execute-script';

//echo $url;

....

$curl = curl_init($url);

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_POST, true);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(

   "Content-Type: application/x-www-form-urlencoded",

);

curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

//script lua

$data = "function OnStoredInstance(instanceId, tags, metadata)

  if tags['Modality'] == 'DX' then

      SendToModality(instanceId, 'gepacs')

  end

  if tags['Modality'] == 'MR' then

      SendToModality(instanceId, 'gepacs')

  end   

  if tags['Modality'] == 'CT' then

      SendToModality(instanceId, 'gepacs')

  end   

end";

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

//for debug only!

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);

curl_close($curl);

var_dump($resp);
