Data via Qt Creator Console from WebSocket

[Samuel123]

Hello,
I would like to know how to output information from a WebSocket via Qt Creator Console. This is my code, which is not working:

#include <QCoreApplication>
#include <QWebSocket>
#include <QtDebug>

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

//WebSocket:
QWebSocket *socket = new QWebSocket();
socket->open(QUrl("ws://IP-Adresse"));

QObject::connect(socket, &QWebSocket::connected, [] () {
	qDebug() << "WebSocket connected";
});

QObject::connect(socket, &QWebSocket::connected, [] (const QString &message) {
	qDebug() << Nachricht: " << message;
});

QObject::connect(socket, &QWebSocket::disconnected, [] () {
	qDebug() << "WebSocket disconnected";
});

socket->close();
return a.exec();

}

Does someone have solutions?

@Samuel123 yes easy one : connect your lambda function to the appropriate signal : use textMessageReceived or binaryMessageReceived which are both intended to be emitted upon message reception on the contrary of connected which wont ever be triggered in that case.

@ankou29666 Thank you for your answer. Can you provide an example of how to integrate that into a code?

@Samuel123 said in Data via Qt Creator Console from WebSocket:

QObject::connect(socket, &QWebSocket::connected, [] (const QString &message) {
qDebug() << Nachricht: " << message;
});

becomes

QObject::connect(socket, &QWebSocket::textMessageReceived, [] (const QString &message) {
	qDebug() << Nachricht: " << message;
});

@ankou29666 I changed it, but it didn't make any difference. Do you know if it's enough to just enter the IP address of the WebSocket after "socket->open"?

Hi,

Why are you closing the socket before calling ˋapp.exec();` ?

@SGaist Now it worked. Thanks very much.
