我正在尝试构建一个简单的Java代码，以使用Google QPX API获取从纽约到伦敦的航类的航类选项。我注册了Google并获得了API_key。
我阅读了文档，但不幸的是，我找不到任何示例向我展示如何执行此操作。
这是我到目前为止尝试过的:
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?
}
}
如果有人可以帮助我完成代码，我将不胜感激。
提前致谢。
