Come utilizzare Google QPX API con Java per la ricerca di volo?
Sto cercando di costruire un semplice codice Java che ottenga opzioni di volo usando l'API di Google QPX, per il volo da New York a Londra. Ho firmato con Google e ottenuto API_key.
Ho letto la documentazione, ma sfortunatamente non sono riuscito a trovare alcun esempio che mi mostri come farlo.
Ecco cosa ho provato finora:
import com.google.api.services.qpxExpress.model.*;
import java.util.*;
public class Main
{
public static void main(String[] args)
{
// Passengers
PassengerCounts passengers = new PassengerCounts();
passengers.setAdultCount(2);
// Slice
List<SliceInput> slices = new ArrayList<SliceInput>();
SliceInput slice = new SliceInput();
slice.setOrigin("JFK"); // John Kennedy Airport in Ney York
slice.setDestination("LHR"); // London Heathrow
slice.setDate("2015-07-01");
slices.add(slice);
// Options request
TripOptionsRequest tripOptions = new TripOptionsRequest();
tripOptions.setPassengers(passengers);
tripOptions.setSlice(slices);
// Search request
TripsSearchRequest tripSearchReq = new TripsSearchRequest();
tripSearchReq.setRequest(tripOptions);
// Next steps?
// Setting up QPXExpress?
}
}
Lo apprezzerò se qualcuno può aiutarmi a completare il codice. Grazie in anticipo.

Questo è un codice semplice, testato con successo, spero che aiuti
