    QSslCertificate cert = QSslCertificate(pem, QSsl::Pem);
    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

Re: qt5mqtt-5.15.2 自带 simpleclient 没有 ssl 支持,添加几行代码支持一下

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

项目地址: https://github.com/qt/qtmqtt

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。
