如何获取wifi列表，有人知道吗？

import { wifiManager } from '@kit.ConnectivityKit';

try {
  let scanInfoList = wifiManager.getScanInfoList();
  console.info('scanInfoList:' + JSON.stringify(scanInfoList));
  let len = scanInfoList.length;
  console.log('wifi received scan info: ' + len);
  if (len > 0) {
    for (let i = 0; i < len; ++i) {
      console.info('ssid: ' + scanInfoList[i].ssid);
      console.info('bssid: ' + scanInfoList[i].bssid);
      console.info('capabilities: ' + scanInfoList[i].capabilities);
      console.info('securityType: ' + scanInfoList[i].securityType);
      console.info('rssi: ' + scanInfoList[i].rssi);
      console.info('band: ' + scanInfoList[i].band);
      console.info('frequency: ' + scanInfoList[i].frequency);
      console.info('channelWidth: ' + scanInfoList[i].channelWidth);
      console.info('timestamp: ' + scanInfoList[i].timestamp);
    }
  }
} catch (error) {
  console.error('failed:' + JSON.stringify(error));
}
