How to access QNetworkReply->readAll()?

I am making a simple get request via the QNetwork access manager, I send the request in the following function (the manager is initiated in the constructor).

void ui_screen::check_api_authenciation(const QString& access_token) {
    //construct the api url
    QUrl api_validation_url(this->API_VALIDATION_URL);
    QNetworkRequest api_validation_request(api_validation_url);
    api_validation_request.setHeader(QNetworkRequest::ServerHeader, "Authorization: token " + access_token);
    mgr->get(api_validation_request);
    connect(mgr, SIGNAL(finished(QNetworkReply*)), this, SLOT(on_authenciation_response_arrive(QNetworkReply*)));


}

and try to receive in the following function

void ui_screen::on_authenciation_response_arrive(QNetworkReply* reply) {

    QByteArray bts = reply->readAll();
    QString str(bts);
    ui->authenciation_progress->setRange(0,100);
    ui->authenciation_progress->setValue(100);
    ui->authenciation_progress_label->setText("Reply arrived");
}

but reply->readAll() triggers the following error

error: member access into incomplete type 'QNetworkReply'

Why couldn't I access the member function?

Solution

  • This error is raised if you're missing some include files.

    You can include the declaration from header file for the QNetworkReply class that will "complete" the type by adding

    #include <QNetworkReply>

    at the top of your file.
