在根目录下创建文件夹并将文件上传到该文件夹​​google drive api

我想使用CURL在googledrive根目录中创建文件夹.文件已上传到驱动器，但是我需要创建一个文件夹并将文件上传到该文件夹​​.

I want to create folder in googledrive root directory using CURL. File is uploaded to drive but I need to create a folder and upload file to that folder.

根据@hanshenrik代码创建文件夹的要求，Move文件不起作用

我的更新代码:

$REDIRECT_URI = 'http' . ($_SERVER['SERVER_PORT'] == 80 ? '' : 's') . '://' . $_SERVER['SERVER_NAME'] . $_SERVER['SCRIPT_NAME'];
$SCOPES = array($GAPIS_AUTH . 'drive', $GAPIS_AUTH . 'drive.file', $GAPIS_AUTH . 'userinfo.email', $GAPIS_AUTH . 'userinfo.profile');
$STORE_PATH = 'credentials.json';

function uploadFile($credentials, $filename, $targetPath,$folderId)
{

    global $GAPIS;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $GAPIS . 'upload/drive/v2/files?uploadType=media');

   //$content =  { title  "mypdf.pdf", description = "mypdf.pdf", mimeType = "application/pdf" };

   $contentArry = array('name' =>'veridoc', 'parents' => array('17dVe2GYpaHYFdFn1by5-TYKU1LXSAwkp'));
   $contentArry = json_encode($contentArry);



    curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
    //curl_setopt($ch, CURLOPT_POSTFIELDS,$contentArry);
    curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents($filename));
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER,
            array('Content-Type : application/pdf','Content-Length:' . filesize($filename),'Authorization: Bearer ' . getAccessToken($credentials))
    );

    $postResult = curl_exec($ch);
    curl_close($ch);

    return json_decode($postResult, true);
}
