使用wifiManager.getScanInfoList方法获取扫描Wi-Fi结果，需要权限：ohos.permission.GET_WIFI_INFO。参考代码如下：
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));
