Use QNetworkAccessManager to send post request between 5000-10000, from one QThread.

[Taz742]

Hi! I have a folder where i have a many databases. It is possible over time, add or remove this database from the folder. So I made QTimer.

In my QThread constructor i read the information to whom to send a message from database.
Now we have a list of people who send the message and in my QThread::run() i start send sms.

Read a databases and start a threads:

    this->timer = new QTimer(this);
    this->timer->setInterval(15000);
    connect(this->timer, &QTimer::timeout, this, [=]() {
        qDebug() << "time outed";
        QString path = "C:\\Program Files\\Daxi\\SMSServer\\cgi\\SMSSenderAllBASE";
        //QString path = qApp->applicationDirPath() + "\\SMSSenderAllBASE";
        QDir recoredDir(path);
        QStringList allFiles = recoredDir.entryList(QDir::NoDotAndDotDot | QDir::System | QDir::Hidden  | QDir::AllDirs | QDir::Files, QDir::DirsFirst);//(QDir::Filter::Files,QDir::SortFlag::NoSort)
        for (int i = 0; i < allFiles.size(); i++) {
            QString fullPath = path + "\\" + allFiles[i];
            QString connectionName = allFiles[i];
            connectionName = connectionName.remove(connectionName.size() - 4, 4);
            {
                QSqlDatabase db = QSqlDatabase::addDatabase("QIBASE", connectionName);
                db.setDatabaseName(fullPath);
                db.setHostName("localhost");
                db.setPort(3050);
                db.setUserName("SYSDBA");
                db.setPassword("masterkey");
            }

            MyPhone *thread = new MyPhone(connectionName, this);
            connect(thread, &MyPhone::finished, thread, &MyPhone::deleteLater);
            thread->start();
        }
    });
    this->timer->start();

To read the information from the database, send messages and write the history of the database and delete records that have already been sent, at a very long time!
How can I send all message to QNetworkAccessManager without QEventLoop?

Do not have any idea? How do I do this correctly?
