Why the post method doesn't send the json to API Rest in QT5?

yea, about those errors i was talking.
Since you are on Ubuntu simply install the OpenSSL binaries (via the system package manager) and it should work.

@raven-worx
I had already installed the package. I run the program but I always make the same error.

Should I use the connectToHostEncrypted method of the QNetworkAccessManager class?

@trip For using https enough call message get/put/post with https urls, for example

QNetworkRequest req;
req.setUrl(QUrl("https://cloud-api.yandex.net/v1/disk/"));

and this is working in my program.

@trip

it has to be in a path where your application can find it.

no not needed. Should all happen internally. Just make sure your application can find the OpenSSL binaries.

@raven-worx for example, we can put together with the executable file.

I tried to do another project where there is just main.cpp and where do

#include <QCoreApplication>
#include <QNetworkAccessManager>
#include <QNetworkReply>
#include <QNetworkRequest>
#include <QDebug>
#include <QObject>
#include <QByteArray>
#include <QUrl>


void replyFinished(QNetworkReply *reply)
{
    reply->deleteLater();
    qDebug() << "reply delete!";
    qDebug() << "https post_request done!";
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QNetworkAccessManager *manager = new QNetworkAccessManager();

    QNetworkRequest request(QUrl ("https://cryptic-reaches-94837.herokuapp.com/data/"));

    request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");

    QObject::connect(manager, &QNetworkAccessManager::finished, replyFinished);

    quint8 speed = 0x12;
    quint8 acceleration = 0x5b;

    QString json = QString("{\"speed\":\"%1\",\"acceleration\":\"%2\"}").arg(speed).arg(acceleration);

    manager->post(request, json.toUtf8());

    return a.exec();
}

and it's work!!!
but how come if add this piece of code to my project, why does not work to me?

@trip
but thats a different URL now?!
Check the returned response error again.

@raven-worx
not only here I left explicit

I think the problem of my code is that networking events are not processed by QCoreApplication :: exec () and then, because the execution is always nested in the cycles and never returns to the main unless there is an error , I do not run networking events. How can I solve this problem?
