    QSslSocket::addDefaultCaCertificate(cert);

    m_client = new QMqttClient(this);

    m_client->setHostname(ui->lineEditHost->text());
    m_client->setPort(ui->spinBoxPort->value());
    m_client->setUsername("user"); //用户名
    m_client->setPassword("password");//密码

m_client->connectToHost();
改为 ==>
m_client->connectToHostEncrypted();

下载：simplemqttclient.tar

ubuntu 编译出现： QtCore/private/qobject_p.h: No such file or directory

解决方法： sudo apt install qtbase5-private-dev

pro 工程文件添加：QT += core-private

如果用的是阿里云申请的免费或者收费CA证书，这段可以不用。
