Prima di utilizzare l'API Location Selection per cercare i punti di prelievo per i passaggi, segui le istruzioni
per l'integrazione con la libreria client .
Il servizio Location Selection fornisce tre API per la selezione dei punti di prelievo e riconsegna: FindNearbyPlaces, FindPickupPointsForPlace e FindPickupPointsForLocation.
Utilizza FindNearbyPlaces per recuperare i luoghi vicini alla posizione di ricerca o del dispositivo. I luoghi sono classificati in base alla vicinanza alla posizione e alla loro importanza per il carpooling. FindNearbyPlaces restituisce un elenco di luoghi che possono essere visualizzati per consentire all'utente di effettuare la selezione migliore. Una volta selezionato un luogo, utilizza FindPickupPointsForPlace per recuperare i punti di prelievo per il luogo selezionato.
Utilizza FindPickupPointsForLocation per recuperare i luoghi e i relativi punti di prelievo nelle vicinanze della posizione di ricerca o del dispositivo nella stessa chiamata RPC.
Ogni punto di prelievo è associato a un luogo. I punti di prelievo sono classificati in base alla vicinanza alla posizione e alla loro importanza per il carpooling. Tieni presente che i punti di prelievo per più luoghi vengono ordinati insieme. FindPickupPointsForLocation combina FindNearbyPlaces e FindPickupPointsForPlace. Ad esempio, supponiamo che la posizione della richiesta sia vicina ai luoghi P1, P2 e P3. Se il punto di prelievo migliore T1 è associato al luogo P2 e il punto di prelievo migliore successivo è associato al luogo P1, i risultati avranno l'ordine [T1:P2, T2:P1, ...].
La classificazione dei punti di prelievo dipende dai criteri forniti nella richiesta.
Per ulteriori informazioni, consulta la sezione
Ottimizzare i prelievi per più viaggi .
Cerca per località
Se preferisci mostrare i luoghi all'utente prima della selezione dei punti di ritiro o visualizzare i luoghi nelle vicinanze trascinando un segnaposto, utilizza la seguente chiamata 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);
La chiamata RPC restituisce un elenco classificato di risposte sui luoghi che soddisfano i criteri di input, ordinati in base a una combinazione di vicinanza e importanza. Puoi consentire al passeggero di scegliere un luogo o utilizzare il primo risultato e procedere alla selezione del punto di prelievo. Ogni risposta sul luogo ha un place_id univoco che può essere utilizzato in FindPickupPointsForPlaceRequest per recuperare i punti di prelievo. Per ulteriori informazioni,
consulta la sezione Cerca per ID luogo .
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);
La chiamata RPC restituisce un elenco classificato di punti di prelievo che soddisfano i criteri di input, ordinati in base a una combinazione di vicinanza e importanza. Questa chiamata RPC combina FindNearbyPlaces e FindPickupPointsForPlaceRequest e può essere utilizzata al posto di combinare le altre due chiamate.
Cerca per ID luogo
Puoi ottenere un place_id utilizzando FindNearbyPlaces o il servizio Autocomplete dell'API Places. Quindi utilizza la seguente chiamata RPC per fornire punti di prelievo ottimali per il luogo specificato:
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 restituisce PickupPointResponses con latitudine e longitudine per i punti in cui è possibile prelevare un passeggero.
Ottimizzare i prelievi per più viaggi
Per i passaggi condivisi o consecutivi, FindPickupPointsForPlace supporta l'ordinamento dei punti di prelievo in base a DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION. In questo modo, puoi restituire un punto di prelievo per il viaggio successivo ottimizzato con il percorso del viaggio attuale dell'autista.

Visualizzare i contorni, gli ingressi e le uscite degli edifici
Nel messaggio di risposta del proto del luogo, il
associatedCompounds
Tipo di composto: una delle quattro opzioni
compoundBuilding : un singolo edificio indipendente, come un centro commerciale o un
supermercato.compoundSection : un composto all'interno di un composto più grande, ad esempio un singolo negozio in un centro commerciale.compoundGrounds : tutto ciò che è associato a un compoundBuilding,
ad esempio un centro commerciale, il suo parcheggio e qualsiasi altro edificio
all'interno del parcheggio.unrecognized : il valore predefinito
Geometria: le coordinate del poligono delineato, archiviate in una struttura GeoJSON nel campo displayBoundary. Queste coordinate vengono utilizzate per costruire il contorno della sezione, dell'edificio o del terreno.
Ingressi: le coordinate di latitudine e longitudine di tutti gli ingressi e le uscite individuati.
Location Selection restituisce qualsiasi tipo di composto associato alla località di ricerca. Se la località di ricerca è in un negozio specifico di
un centro commerciale, Location Selection restituisce:
* il negozio specifico, i suoi ingressi e le sue uscite e il contorno del negozio
* l'edificio composto (il centro commerciale), i suoi ingressi e le sue uscite e il contorno del centro commerciale
* i terreni composti (il centro commerciale + il parcheggio), i loro ingressi e le loro uscite e il contorno dell'intero terreno
Questa immagine mostra tutti e tre i tipi di composti restituiti.
Questa immagine mostra diverse località all'interno di un aeroporto, con il confine di un edificio all'interno dell'aeroporto e il confine dell'aeroporto e di tutti i terreni correlati.
