How to confirm successful sending of single chat messages

[yuanshengyong]

Hello, may I ask how to confirm that this message has been sent normally after calling the sendpacket interface? Currently, only group chat and errors will receive the messageReceived signal

You can use QXmppClient::send() (see https://doc.qxmpp.org/qxmpp-1/classQXmppClient.html#a750350f089a0e45e1aee3d032e84980c).

for example, like this (untested)

QXmppMessage msg;
client->send(std::move(msg)).then(this, [](auto result) {
  if (auto success = std::get_if<QXmpp::SendSuccess>(&result)) {
    qDebug() << "Sent packet" << "got acknowledgement from local server:" << success->acknowledged;
  } else {
    auto error = std::get<QXmppError>(result);
    qDebug() << "Error sending message:" << error.description;
  }
})
