upload an executable file using QNetworkAccessManager

[milli]

I want to upload an executable file to the server.My code is this:

QString data;
    QByteArray dataToSend; // byte array to be sent in POST
    QFile *inputFile=new QFile("putty.exe");
 
   if(!inputFile->open(QIODevice::ReadOnly))
        return;
 
    data+="\nContent-Disposition: form-data; ";
 
    data+=QString("name=\"%1\"; ").arg(name);//putty
    data+=QString("filename=\"%1\";").arg(filepath);//http://localhost/uploadFiles/sdda/putty.exe
    data+="Content-Type: application/octet-stream" +inputFile->readAll();
 
    dataToSend=data.toUtf8(); // convert data string to byte array for request
 
    // request init
    QNetworkRequest request(QUrl("http://localhost/uploadFile.php"));
    request.setRawHeader("Content-Type"," multipart/form-data; boundary=\"-----------------------------7d935033608e2\"");
    request.setHeader(QNetworkRequest::ContentLengthHeader,dataToSend.size());

QString data;
    QByteArray dataToSend; // byte array to be sent in POST
    QFile *inputFile=new QFile("putty.exe");

   if(!inputFile->open(QIODevice::ReadOnly))
        return;

    data+="\nContent-Disposition: form-data; ";

    data+=QString("name=\"%1\"; ").arg(name);//putty
    data+=QString("filename=\"%1\";").arg(filepath);//http://localhost/uploadFiles/sdda/putty.exe
    data+="Content-Type: application/octet-stream" +inputFile->readAll();

    dataToSend=data.toUtf8(); // convert data string to byte array for request

    // request init
    QNetworkRequest request(QUrl("http://localhost/uploadFile.php"));
    request.setRawHeader("Content-Type"," multipart/form-data; boundary=\"-----------------------------7d935033608e2\"");
    request.setHeader(QNetworkRequest::ContentLengthHeader,dataToSend.size());

Running this code the result is:a warning that informs me that a folder in which i want to upload the file already exists.Is the above approach correct?

//php script

<
?php
 
 
$packageName = trim($_POST['packageName']);
mkdir("uploadFiles/$packageName");
// Upload file
move_uploaded_file ($_FILES['uploadFile'] ['tmp_name'], "uploads/$packageName/{$_FILES['uploadFile'] ['name']}")
 
?>

<
?php

 
$packageName = trim($_POST['packageName']);
mkdir("uploadFiles/$packageName");
// Upload file
move_uploaded_file ($_FILES['uploadFile'] ['tmp_name'], "uploads/$packageName/{$_FILES['uploadFile'] ['name']}")

?>
