我在 Kubernetes (minikube) 上安装了一个测试用例，它在浏览器中显示了一个 WordPress 站点。该示例取自Example: Deploying WordPress and MySQL with Persistent Volumes。告诉我，如何将负责显示网站的服务连接到专用 IP 地址？因此，通过输入专用 IP 地址，我可以访问托管在我的 Kubernetes 集群中的站点。

在我loadJsonData填充数据的方法中QJsonObject。我从这个对象创建QJsonDocument. 我转换QString并保存在一个文件中。我希望我填写的顺序QJsonObject保留在文件中。告诉我怎么做。

QJsonDocument doc(loadJsonData(Element));
saveFile(doc.toJson(QJsonDocument::Indented));

QJsonObject *TreeModel::loadJsonData(SCommonElement *curElement)
{
 QJsonObject *joElement = new QJsonObject;

 joElement->insert(JS_ABSOLUTEID,       QJsonValue::fromVariant(curElement->elementConf.absoluteId));
 joElement->insert(JS_PRIVATEID,        QJsonValue::fromVariant(curElement->elementConf.privateId)); 
 joElement->insert(JS_COMPOSITENAME,    QJsonValue::fromVariant(curElement->elementConf.compositeName));
 joElement->insert(JS_PRIVATENAME,      QJsonValue::fromVariant(curElement->elementConf.privateName));
 joElement->insert(JS_DTCREATE,         QJsonValue::fromVariant(curElement->elementConf.dtCreate));
 joElement->insert(JS_DTMODIFY,         QJsonValue::fromVariant(curElement->elementConf.dtModify));
 joElement->insert(JS_COMMENTS,         QJsonValue::fromVariant(curElement->elementConf.comments));
 joElement->insert(JS_CHILDNEXTID,      QJsonValue::fromVariant(curElement->elementConf.childNextId));

 return joElement;
} 

void TreeModel::saveFile(QString Source)
{
 QString FilePath="d:/Data.json";
 QFile file(FilePath);

 if(!file.open(QIODevice::WriteOnly | QIODevice::Text))
 {
    QMessageBox::critical(NULL, QObject::tr("Saving file"), QString("Error saving file [%1]. Check existing configuration file!\nSystem error - %2").arg(FilePath).arg(file.errorString()));
    return;
 }
 QTextStream stream(&file);
 stream << Source << endl;
}

结果：

{
 "absoluteId": 1000001,
 "childNextId": 4,
 "comments": "This is fork 1",
 "compositeName":   "module100_path1_path2_class1_fork1",
 "dtCreate": "2017-08-31 10:44:42",
 "dtModify": "2017-08-31 10:44:42",
 "privateId": 0,
 "privateName": "fork1"
}
