Zanim zaczniesz korzystać z interfejsu Location Selection API do wyszukiwania punktów odbioru przejazdów, postępuj zgodnie z instrukcjami integracji z biblioteką klienta.
Usługa wyboru lokalizacji udostępnia 3 interfejsy API do wyboru miejsca odbioru i zwrotu: FindNearbyPlaces, FindPickupPointsForPlace i FindPickupPointsForLocation.
Użyj FindNearbyPlaces, aby pobrać miejsca w pobliżu wyszukiwania lub lokalizacji urządzenia. Miejsca są uporządkowane według odległości od lokalizacji i ich znaczenia w przypadku przejazdów. FindNearbyPlaces zwraca listę miejsc, które można wyświetlić, aby użytkownik mógł dokonać najlepszego wyboru. Po wybraniu miejsca użyj FindPickupPointsForPlace, aby pobrać punkty odbioru dla wybranego miejsca.
Użyj FindPickupPointsForLocation, aby pobrać miejsca i powiązane z nimi punkty odbioru w pobliżu wyszukiwania lub lokalizacji urządzenia w ramach tego samego wywołania RPC.
Każdy punkt odbioru jest powiązany z miejscem. Punkty odbioru są klasyfikowane według odległości od lokalizacji i ich znaczenia dla usług transportu zbiorowego. Pamiętaj, że punkty odbioru w przypadku wielu miejsc są uporządkowane razem. FindPickupPointsForLocation łączy FindNearbyPlaces i FindPickupPointsForPlace. Załóżmy na przykład, że lokalizacja żądania znajduje się w pobliżu miejsc M1, M2 i M3. Jeśli najlepszy punkt odbioru T1 jest powiązany z miejscem P2, a kolejny najlepszy punkt odbioru jest powiązany z miejscem P1, wyniki będą uporządkowane w ten sposób: [T1:P2, T2:P1, ...].
Kolejność punktów odbioru zależy od kryteriów podanych w żądaniu.
Więcej informacji znajdziesz w artykule Optymalizacja odbiorów w przypadku wielu przejazdów.
Szukaj według lokalizacji
Jeśli wolisz wyświetlać użytkownikowi miejsca przed wyborem punktów odbioru lub wyświetlać miejsca w pobliżu, przeciągając pinezkę, użyj tego wywołania RPC:
FindNearbyPlacesRequest find_nearby_places_request =
FindNearbyPlacesRequest.newBuilder()
.setLocalizationPreferences(LocalizationPreferences.newBuilder()
// Language used for localizing text such as name or address.
.setLanguageCode("en")
.setRegionCode("US")
.build())
// Rider's location or location of dragged pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.365647).setLongitude(-121.925356))
// Number of places requested.
.setMaxResults(3)
.build();
FindNearbyPlacesResponse findNearbyPlacesResponse =
locationSelectionBetaClient.findNearbyPlaces(find_nearby_places_request);
Wywołanie RPC zwraca uporządkowaną listę odpowiedzi dotyczących miejsc, które spełniają kryteria wejściowe, posortowaną według kombinacji bliskości i popularności. Możesz pozwolić pasażerowi wybrać miejsce lub użyć pierwszego wyniku i przejść do wyboru miejsca odbioru. Każda odpowiedź dotycząca miejsca ma unikalny identyfikator place_id, którego można użyć w FindPickupPointsForPlaceRequest, aby pobrać punkty odbioru. Więcej informacji znajdziesz w artykule Wyszukiwanie według identyfikatora miejsca.
FindPickupPointsForLocationRequest FindPickupPointsForLocationRequest =
FindPickupPointsForLocationRequest.newBuilder()
// Language used for localizing text such as name and address.
.setLocalizationPreferences(LocalizationPreferences.newBuilder().setRegionCode("US").setLanguageCode("en"))
// The search location of the rider or the dropped pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(-23.482049).setLongitude(-46.602135))
// The max results returned.
.setMaxResults(5)
// List of travel modes. At least one of the travel modes must be supported by the pickup points.
.addTravelModes(TravelMode.DRIVING)
// Specifies the sorting order of matching pickup points.
.setOrderBy(PickupPointOrder.DISTANCE_FROM_SEARCH_LOCATION)
.build();
FindPickupPointsForLocationResponse FindPickupPointsForLocationResponse =
locationSelectionService.FindPickupPointsForLocation(
RpcClientContext.create(), FindPickupPointsForLocationRequest);
Wywołanie RPC zwraca uporządkowaną listę punktów odbioru, które spełniają kryteria wejściowe, posortowaną według kombinacji bliskości i widoczności. To wywołanie RPC łączy FindNearbyPlaces i FindPickupPointsForPlaceRequest i może być używane zamiast łączenia pozostałych 2 wywołań.
Wyszukiwanie według identyfikatora miejsca
place_id możesz uzyskać za pomocą FindNearbyPlaces lub usługi autouzupełniania interfejsu Places API. Następnie użyj tego wywołania RPC, aby podać optymalne punkty odbioru dla określonego miejsca:
FindPickupPointsForPlaceRequest findPickupPointsForPlaceRequest =
FindPickupPointsForPlaceRequest.newBuilder()
// Language used for localizing text such as name and address.
.setLocalizationPreferences(LocalizationPreferences.newBuilder().setRegionCode("US").setLanguageCode("en"))
// Place ID of the place for which pickup points are being fetched;
// for example, Hilton Hotel, Downtown San Jose.
.setPlaceId("ChIJwTUa-q_Mj4ARff4yludGH-M")
// List of travel modes. At least one of the travel modes must be supported by the pickup points.
.addTravelModes(TravelMode.DRIVING)
// Rider's location or location of dragged pin.
// It is recommended to use the same location that was used in `FindNearbyPlaces` for better quality.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
.setOrderBy(PickupPointOrder.DISTANCE_FROM_SEARCH_LOCATION)
.setMaxResults(5)
.build();
FindPickupPointsForPlaceResponse findPickupPointsForPlaceResponse =
locationSelectionBetaClient.findPickupPointsForPlace(findPickupPointsForPlaceRequest);
FindPickupPointsForPlace zwraca PickupPointResponses z szerokością i długością geograficzną punktów, w których można odebrać pasażera.
Optymalizacja odbiorów pod kątem wielu przejazdów
W przypadku przejazdów współdzielonych lub następujących po sobie FindPickupPointsForPlace obsługuje zamawianie punktów odbioru według DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION. Dzięki temu możesz zwrócić punkt odbioru dla następnego przejazdu, który jest zoptymalizowany pod kątem trasy bieżącego przejazdu kierowcy.

Wyświetlanie obrysów budynków, wejść i wyjść
W wiadomości odpowiedzi proto dotyczącej miejsca pole associatedCompounds identyfikuje związki chemiczne powiązane z miejscem. Wiadomość złożona zawiera 3 rodzaje informacji:
- Typ złożony – jedna z 4 opcji:
compoundBuilding – pojedynczy, wolnostojący budynek, np. centrum handlowe lub supermarket.
compoundSection – obiekt w większym obiekcie, np. pojedynczy sklep w galerii handlowej.
compoundGrounds – wszystko, co jest powiązane z compoundBuilding, np. centrum handlowe, parking i inne budynki na tym parkingu.
unrecognized – wartość domyślna
- Geometria – współrzędne wielokąta, przechowywane w strukturze GeoJSON w polu
displayBoundary. Te współrzędne służą do tworzenia konturu sekcji, budynku lub terenu.
- Wejścia – współrzędne szerokości i długości geograficznej wszystkich znalezionych wejść i wyjść.
Funkcja wyboru lokalizacji zwraca dowolny typ złożony powiązany z lokalizacją wyszukiwania. Jeśli lokalizacja wyszukiwania znajduje się w konkretnym sklepie w centrum handlowym, interfejs Location Selection zwraca: * konkretny sklep, jego wejścia i wyjścia oraz zarys sklepu; * budynek złożony (centrum handlowe), jego wejścia i wyjścia oraz zarys centrum handlowego; * teren złożony (centrum handlowe + parking), jego wejścia i wyjścia oraz zarys całego terenu.
Obraz przedstawia wszystkie 3 typy złożone.
