Avant d'utiliser l'API Location Selection pour rechercher des points de prise en charge de trajets, suivez les instructions d'intégration à la bibliothèque cliente.

Le service Location Selection fournit trois API pour la sélection des points de prise en charge et de dépose : FindNearbyPlaces, FindPickupPointsForPlace et FindPickupPointsForLocation.

Utilisez FindNearbyPlaces pour récupérer les lieux à proximité de la recherche ou de la position de l'appareil. Les lieux sont classés par proximité de l'emplacement et par importance pour le covoiturage. FindNearbyPlaces renvoie une liste de lieux qui peuvent être affichés pour permettre à l'utilisateur de faire le meilleur choix. Une fois un lieu sélectionné, utilisez FindPickupPointsForPlace pour récupérer les points de prise en charge de ce lieu.

Utilisez FindPickupPointsForLocation pour récupérer les lieux et leurs points de prise en charge associés à proximité de la recherche ou de la position de l'appareil dans le même appel RPC. Chaque point de prise en charge est associé à un lieu. Les points de prise en charge sont classés par proximité de l'emplacement et par importance pour le covoiturage. Notez que les points de prise en charge de plusieurs lieux sont classés ensemble. FindPickupPointsForLocation combine FindNearbyPlaces et FindPickupPointsForPlace. Supposons, par exemple, que le lieu de la requête se trouve à proximité des lieux P1, P2 et P3. Si le meilleur point de prise en charge T1 est associé au lieu P2 et que le point de prise en charge suivant est associé au lieu P1, les résultats seront classés comme suit : [T1:P2, T2:P1, ...].

Le classement des points de prise en charge dépend des critères fournis dans la requête. Pour en savoir plus, consultez Optimiser les prises en charge pour plusieurs trajets.

Rechercher par lieu

Si vous préférez afficher les lieux à l'utilisateur avant qu'il ne sélectionne les points de prise en charge, ou afficher les lieux à proximité en faisant glisser un repère, utilisez l'appel RPC suivant :

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);

L'appel RPC renvoie une liste classée de réponses de lieux qui répondent aux critères d'entrée, classées selon une combinaison de proximité et d'importance. Vous pouvez laisser le passager choisir un lieu ou utiliser le premier résultat et passer à la sélection du point de prise en charge. Chaque réponse de lieu possède un place_id unique qui peut être utilisé dans FindPickupPointsForPlaceRequest pour récupérer les points de prise en charge. Pour en savoir plus, consultez Rechercher par ID de lieu.

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);

L'appel RPC renvoie une liste classée de points de prise en charge qui répondent aux critères d'entrée, classés selon une combinaison de proximité et d'importance. Cet appel RPC combine FindNearbyPlaces et FindPickupPointsForPlaceRequest, et peut être utilisé à la place des deux autres appels.

Rechercher par ID de lieu

Vous pouvez obtenir un place_id à l'aide de FindNearbyPlaces ou du service Autocomplete de l'API Places. Utilisez ensuite l'appel RPC suivant pour fournir des points de prise en charge optimaux pour le lieu spécifié :

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 renvoie des PickupPointResponses avec la latitude et la longitude des points où un passager peut être pris en charge.

Optimiser les prises en charge pour plusieurs trajets

Pour les trajets partagés ou consécutifs, FindPickupPointsForPlace permet de classer les points de prise en charge par DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION. Vous pouvez ainsi renvoyer un point de prise en charge pour le trajet suivant, optimisé en fonction de l'itinéraire actuel du conducteur.

Exemple

FindPickupPointsForPlaceRequest findPickupPointsForPlaceRequest =

Afficher les contours, les entrées et les sorties des bâtiments

Dans le message de réponse proto du lieu, le associatedCompounds champ identifie les composés associés au lieu. Le message composé contient trois types d'informations :

  • Type de composé : l'une des quatre options
    • compoundBuilding : un bâtiment autonome unique, tel qu'un centre commercial ou un supermarché.
    • compoundSection : un composé au sein d'un composé plus grand, tel qu'un seul magasin dans un centre commercial.
    • compoundGrounds : tout ce qui est associé à un compoundBuilding, tel qu'un centre commercial, son parking et tout autre bâtiment situé dans ce parking.
    • unrecognized : la valeur par défaut
  • Géométrie : les coordonnées du polygone délimité, stockées dans une structure GeoJSON dans le champ displayBoundary. Ces coordonnées sont utilisées pour construire le contour de la section, du bâtiment ou du terrain.
  • Entrées : les coordonnées de latitude et de longitude de toutes les entrées et sorties trouvées.

Location Selection renvoie n'importe quel type de composé associé au lieu de recherche. Si le lieu de recherche se trouve dans un magasin particulier d' un centre commercial, Location Selection renvoie : * le magasin spécifique, ses entrées et sorties, et son contour * le bâtiment composé (le centre commercial), ses entrées et sorties, et son contour * le terrain composé (le centre commercial + le parking), ses entrées et sorties, et le contour de l'ensemble du terrain

Cette image montre les trois types de composés renvoyés.
