HarmonyOS 鸿蒙Next如何获取同个wifi下的局域网的设备ip和mac地址，做个蹭网查询功能

wifiManager.getLinkedInfo().then(data => {
            console.info("get wifi linked info: " + JSON.stringify(data));
          }).catch((error:number) => {
            console.info(“get linked info error”);
          });

let netHandle = await connection.getDefaultNet();

          if (netHandle) {
            let connectionProperties = await connection.getConnectionProperties(netHandle)
            if (connectionProperties && connectionProperties.linkAddresses) {
              connectionProperties.linkAddresses.forEach((address: connection.LinkAddress, index: number) => {
                console.info("get address info: " + JSON.stringify(address));
              })
            }
          }
