Getting Secondary.Address

There are a number to get the address of a secondary server belonging to an atSign.

  • You have the atSign and rootUrl
// Use Secondary.AddressFinder
String ROOT_URL = "root.atsign.org:64";
String ATSIGN_STR = "@bob";
        
AtSign atSign = new AtSign(ATSIGN_STR);
Secondary.AddressFinder saFinder = ArgsUtil.createAddressFinder(ROOT_URL);
Secondary.Address sAddress = null;
try {
    sAddress = saFinder.findSecondary(atSign);
} catch (NoSuchSecondaryException | IOException e) {
    System.err.println(e);
    e.printStackTrace();
}

// use sAddress
  • You have the host and port of the secondary server
// Use Secondary.Address constructor
String HOST = "ddbe1816-f40f-5b9f-bb2a-ba1492b93aec.staging0001.atsign.zone";
int PORT = 3198;

Secondary.Address sAddress = new Secondary.Address(HOST, PORT);

// use sAddress
