import { EditableLeftIconType } from '[@kit](/user/kit).ArkUI';
import { wifiManager } from '[@kit](/user/kit).ConnectivityKit';

[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
  [@State](/user/State) message: string = 'Hello World';

  build() {
    Column(){
      Text('wifi').onClick(()=>{
        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);
