Send Headers in a QOAuth2AuthorizationCodeFlow request

Question

I am using networkauth for connecting to an OAuth application. I have been able to successfully authenticate after I receive the QOAuth2AuthorizationCodeFlow::granted signal.

Had it been a normal QNAM request, it would have been easy. But with networkauth, I don't have access to AccessToken. So I cannot directly send a QNAM request

Now, what is the correct way to send an additional header with my request? Here is my code

// private 
// QOAuth2AuthorizationCodeFlow * myObject

connect(this->myObject, &QOAuth2AuthorizationCodeFlow::granted, [=](){
        qDebug() << __FUNCTION__ << __LINE__ << "Access Granted!";

        auto m_networkReply = this->myObject->post(QUrl("API_URL"));
// Here I need to post a header in m_networkReply
// setHeader(QNetworkRequest::ContentTypeHeader,"application/json")
// How do I do it?

        connect(m_networkReply, &QNetworkReply::finished, [=](){
            qDebug() << "REQUEST FINISHED. Error? " << (m_networkReply->error() != QNetworkReply::NoError);
            qDebug() << m_networkReply->readAll();
        });
    });

Answer 1

AccessToken can be obtained by this->myObject->token() and the header can be set using:

m_networkRequest.setRawHeader("Authorization", 
                              "Bearer " + this->myObject->token().toUtf8());

So my code snippet becomes:

// private 
// QOAuth2AuthorizationCodeFlow * myObject

connect(this->myObject, &QOAuth2AuthorizationCodeFlow::granted, [=](){
        qDebug() << __FUNCTION__ << __LINE__ << "Access Granted!";

        QJsonObject obj;
        obj.insert("param1", "someval");

        QJsonDocument doc(obj);
        QString strJson(doc.toJson(QJsonDocument::Compact));

        QNetworkRequest m_networkRequest;
        m_networkRequest.setUrl(QUrl("API_URL"));

        m_networkRequest.setHeader(QNetworkRequest::ContentTypeHeader,"application/json");
        m_networkRequest.setRawHeader("Authorization", "Bearer " + this->myObject->token().toUtf8());

        auto m_networkReply = m_networkAccessManager->post(m_networkRequest, strJson.toUtf8());

        connect(m_networkReply, &QNetworkReply::finished, [=](){
            qDebug() << "REQUEST FINISHED. Error? " << (m_networkReply->error() != QNetworkReply::NoError);
            qDebug() << m_networkReply->readAll();
        });
    });
