Socket supports only IP address access, but not domain name access. A domain name can be resolved to the corresponding IP address through DNS.
The code snippet is as follows:
import { connection } from '@kit.NetworkKit';
import { BusinessError } from "@kit.BasicServicesKit"
connection.getAddressesByName("xxxx", (error: BusinessError, data: connection.NetAddress[]) => {
console.log(JSON.stringify(error));
console.log(JSON.stringify(data));
}) Reference
