Qt5、C++11 获取wifi列表与wifi连接

一、获取wifi列表
 

.h 文件内容

#include <QWidget>
#include <QVBoxLayout>
#include <QPushButton>
#include <QCheckBox>
#include <QListWidget>


class Setting : public QWidget {

Q_OBJECT
public:
    explicit Setting(QWidget *parent = nullptr);

signals:
private slots:
    void scanWifiList();

private:

};

#endif //WIFIUDPSCANTOTAL_SETTING_H

.cpp 文件

//
// Created by Administrator on 2025/5/20.
//
#include <QLineEdit>
#include <QLabel>
#include "include/setting/Setting.h"
#include "include/configManager/ConfigManager.h"
#include "include/wifiManager/wifiManager.h"
#include <QDebug>
#include <QMap>
#include <QJsonObject>
#include <QListWidget>
#include <QMessageBox>
#include <QProcess>

#define COUT qDebug() << __FUNCTION__ << __LINE__


void Setting::scanWifiList() {
    qInfo() << "开始扫描wifi列表...";
    wifiList->clear();

    QProcess process;
    process.start("netsh wlan show networks");  // 执行WiFi扫描命令:ml-citation{ref="1,4" data="citationList"}
    process.waitForFinished();
    QString output = QString::fromLocal8Bit(process.readAllStandardOutput());

    QStringList lines = output.split("\r\n");
        foreach (QString line, lines) {
            if (line.contains("SSID")) {

                QString ssid = line.split(":").last().trimmed();
                qInfo() << "wifi..name.."<< ssid;

                wifiList->addItem(ssid);
            }
        }

    COUT << "扫描结束，wifi数量:" << wifiList->count();
    COUT << wifiList;

}

结果如下：
