[ARASHz4]

Hi
I want send a message to telegram bot with http post
this is my code

    QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

    QHttpPart textPart1;
    textPart1.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/x-www-form-urlencoded"));
    textPart1.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; text=\"chat_id\""));
    textPart1.setBody(QString("@user").toUtf8());

    QHttpPart textPart2;
    textPart2.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/x-www-form-urlencoded"));
    textPart2.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; text=\"text\""));
    textPart2.setBody(QString("my text").toUtf8());

    multiPart->append(textPart1);
    multiPart->append(textPart2);

    QUrl url("https://api.telegram.org/bot" + token + "/sendMessage");
    QNetworkRequest request(url);

    QNetworkAccessManager manager;
    QNetworkReply *reply = manager.post(request, multiPart);
    multiPart->setParent(reply);

This a bug in Qt or my code have a problem?

Hi,

There's no code related to error checking. You should connect the QNetworkReply::error signal to get more information about what is happening.

@SGaist i connect the QNetworkReply::error signal

connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(error(QNetworkReply::NetworkError)));

Error is :

Error transferring https://api.telegram.org/botToken/sendMessage - server replied: Bad Request
