From reading https://www.qtcentre.org/threads/18728-qFromBigEndian(-)-not-found , it seems I need to specify the type explicitly.从阅读https://www.qtcentre.org/threads/18728-qFromBigEndian(-)-not-found ，看来我需要明确指定类型。
qDebug() << qFromBigEndian<uint32_t>(message.data());
instead of代替
qDebug() << qFromBigEndian(message.data());
