Hello.

Maybe the English will be better for you? I think russian is not native language for you, or did I mistake?

Did I undesrtood rightly, that you mean this documentation ( SendMultipleMessage_V4_get ) ?

Sorry, my English is not very good too. I mean, I want to write an application to send messages from the computer, they allow me to send request HTTP: http://rest.esms.vn/MainService.svc/json/SendMultipleMessage_V4_get?Phone=09xxxx&Content=DemoeSMS&ApiKey=xxxx&SecretKey=xxxx&SmsType=2&Brandname=abcabc

This is very new to me,
I want to see some examples of it or something similar.

Sorry, my English is not very good too

It`s no problem. Just I think the English will be better for your understanding, because we will have more similar level in language.

I have several examples with QNetworkAccessManager:

• Qt/C++ - Lesson 041. JSON file – How to get from site and parsing it
• Qt/C++ - Tutorial 066. Uploading files to an FTP server
• Qt/C++ - Lesson 065. The correspondence of HTTP errors to server response errors in QNetworkAccessManager
• Qt/C++ - Lesson 035. Downloading files via HTTP with QNetworkAccessManager
• Qt/C++ Tutorial 080. Downloading large files with QNetworkAccessManager

I think, you can use part of code from this Qt/C++ - Lesson 041. JSON file – How to get from site and parsing it

Just you need make some changes here

Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);

    networkManager = new QNetworkAccessManager();
    // Connect networkManager response to the handler
    connect(networkManager, &QNetworkAccessManager::finished, this, &Widget::onResult);
    // We get the data, namely JSON file from a site on a particular url
    networkManager->get(QNetworkRequest(QUrl("http://www.evileg.ru/it_example.json")));
}

For example

connect(networkManager, &QNetworkAccessManager::finished, this, &Widget::onResult);
// We get the data, namely JSON file from a site on a particular url
networkManager->get(QNetworkRequest(QUrl(QString("http://rest.esms.vn/MainService.svc/json/SendMultipleMessage_V4_get?Phone=%1&Content=%2&ApiKey=%3&SecretKey=%4&SmsType=%5&Brandname=%6").arg("09xxxx").arg("DemoeSMS").arg("xxxx").arg("xxxx").arg("2").arg("abcabc");

And make changes in onResult slot

void Widget::onResult(QNetworkReply *reply)
{
    if(!reply->error()){
        qDebug() << "No errors";
    }
    reply->deleteLater();
}

Thanks very much for your help. :D
i'll try it.
