How to put QByteArray into QJsonObject

[enne9]

Let's say I have a custom class for which I already implemented:

friend QDataStream &operator<<(QDataStream& out, const CustomClass& c);
friend QDataStream &operator>>(QDataStream& in, CustomClass& c);

How can I put the QByteArray extracted using QDataSteam into a QJsonObject?
Here, my not successful attempt:

CustomClass c{};
QByteArray data;
QDataStream in(&data, QIODevice::WriteOnly);
in << c;

QJsonObject message;
message["type"] = QStringLiteral("login");
message["binary"] = data.data();

Thanks

Json doesn't support binary data.
You can encode data to hex string or base64 string.

Thanks, got it.

message["binary"] = QString(data.toBase64());
