Qt：获取WIFI列表

示例：使用QT来获取Windows电脑WIFI列表中所有WIFI的名称，实际是执行CMD命令来完成（netsh wlan show networks）

// 获取WIFI列表
QProcess process;
process.start("netsh wlan show networks");
process.waitForStarted();
process.waitForFinished();
QString cmd_res_text = QString::fromLocal8Bit(process.readAllStandardOutput());

//qDebug() << cmd_res_text;
// 提取有效数据
QStringList cmd_res_list_old = cmd_res_text.split("\r\n");
QStringList cmd_res_list;
for (int i = 0; i < cmd_res_list_old.count(); i++)
{
    if (cmd_res_list_old.at(i).contains("SSID")) { cmd_res_list.push_back(cmd_res_list_old.at(i)); }
}

// 提取WIFI名称
QStringList wifi_name_list;
for each (QString i in cmd_res_list) 
{ 
    QStringList temp_list = i.split(" ");
    QString temp_wifi_name = temp_list.last();
    if (!temp_wifi_name.isEmpty()) { wifi_name_list.push_back(temp_wifi_name); }
}

// 添加到下拉框
for each (QString name in wifi_name_list)
{
    ui.comboBox->addItem(name);
}
