qt 实现获取wifimesh 的信号强度

要在Qt中获取WiFi Mesh的信号强度，您需要使用Qt的QNetworkConfigurationManager类和QNetworkSession类。以下是一个示例：

#include <QtNetwork/QNetworkConfigurationManager>
#include <QtNetwork/QNetworkSession>
#include <QDebug>

void printSignalStrength()
{
    QNetworkConfigurationManager manager;
    QNetworkConfiguration cfg = manager.defaultConfiguration();

    if (cfg.state() & QNetworkConfiguration::Discovered) {
        QNetworkSession session(cfg);
        session.open();
        QNetworkInterface iface = session.interface();
        QList<QNetworkAddressEntry> entries = iface.addressEntries();
        foreach (QNetworkAddressEntry entry, entries) {
            if (entry.ip().protocol() == QAbstractSocket::IPv4Protocol) {
                QList<QNetworkInterface> ifaces = QNetworkInterface::allInterfaces();
                foreach (QNetworkInterface ifc, ifaces) {
                    if (ifc.hardwareAddress() == iface.hardwareAddress()) {
                        QList<QNetworkAddressEntry> ifcEntries = ifc.addressEntries();
                        foreach (QNetworkAddressEntry ifcEntry, ifcEntries) {
                            if (ifcEntry.ip().protocol() == QAbstractSocket::IPv4Protocol) {
                                qDebug() << "Signal strength:" << ifcEntry.ip().toString() << ifcEntry.netmask().toString() << ifcEntry.broadcast().toString();
                                break;
                            }
                        }
                        break;
                    }
                }
                break;
            }
        }
        session.close();
    }
}

这个函数将打印WiFi Mesh网络接口的IP地址、子网掩码和广播地址以及信号强度。您可以在您的Qt应用程序中调用此函数来获取WiFi Mesh的信号强度。
