Перед использованием API выбора местоположения для поиска точек посадки следуйте инструкциям по интеграции с клиентской библиотекой .
Служба выбора местоположения предоставляет три API для выбора места посадки и высадки: FindNearbyPlaces , FindPickupPointsForPlace и FindPickupPointsForLocation .
Используйте FindNearbyPlaces для поиска мест рядом с поисковым запросом или местоположением устройства. Места ранжируются по близости к месту и их популярности для совместных поездок. FindNearbyPlaces возвращает список мест, которые можно отобразить, чтобы пользователь мог сделать оптимальный выбор. После выбора места используйте FindPickupPointsForPlace для поиска точек посадки для выбранного места.
Используйте FindPickupPointsForLocation для поиска мест и связанных с ними точек посадки рядом с поиском или местоположением устройства в одном вызове RPC. Каждая точка посадки связана с определенным местом. Точки посадки ранжируются по близости к местоположению и их значимости для совместных поездок. Обратите внимание, что точки посадки для нескольких мест упорядочиваются вместе. FindPickupPointsForLocation объединяет FindNearbyPlaces и FindPickupPointsForPlace . Например, предположим, что запрашиваемое место находится рядом с местами P1, P2 и P3. Если наилучшая точка посадки T1 связана с местом P2, а следующая наилучшая точка посадки связана с местом P1, результаты будут иметь следующий порядок [T1:P2, T2:P1, ...].
Рейтинг пунктов выдачи зависит от критериев, указанных в запросе. Подробнее см. в разделе «Оптимизация пунктов выдачи для нескольких поездок» .
Поиск по местоположению
Если вы предпочитаете отображать места пользователю до выбора точек посадки или отображать близлежащие места путем перетаскивания булавки, используйте следующий вызов 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);
Вызов RPC возвращает ранжированный список ответов на выбор мест, удовлетворяющих входным критериям, упорядоченный по сочетанию близости и известности. Вы можете позволить пассажиру выбрать место или использовать первый результат и перейти к выбору пункта посадки. Каждый ответ на выбор места имеет уникальный place_id , который можно использовать в FindPickupPointsForPlaceRequest для поиска пунктов посадки. Подробнее см. в разделе Поиск по идентификатору места .
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);
Вызов RPC возвращает ранжированный список пунктов самовывоза, удовлетворяющих заданным критериям, упорядоченный по сочетанию близости и известности. Этот вызов RPC объединяет FindNearbyPlaces и FindPickupPointsForPlaceRequest и может использоваться вместо объединения двух других вызовов.
Поиск по идентификатору места
Вы можете получить place_id с помощью FindNearbyPlaces или сервиса автозаполнения Places API. Затем используйте следующий вызов RPC, чтобы найти оптимальные точки забора для указанного места:
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 возвращает PickupPointResponses с широтой и долготой точек, где можно подобрать пассажира.
Оптимизируйте посадку для многократных поездок
Для совместных или частых поездок FindPickupPointsForPlace поддерживает упорядочивание точек посадки по DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION . Это позволяет вам найти точку посадки для следующей поездки, оптимизированную с учетом текущего маршрута водителя.
Пример
FindPickupPointsForPlaceRequest findPickupPointsForPlaceRequest =
FindPickupPointsForPlaceRequest.newBuilder()
// Language used for localizing text such as name and address.

// 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)
// Second rider's location or location of dragged pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
// Location of the driver's next drop off after picking up the second
// rider. Note, it is not necessarily the second rider's destination.
.setDestination(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
.setOrderBy(PickupPointOrder.DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION)
.setComputeDrivingEta(true)
.setMaxResults(5)

Отображение контуров здания, входов и выходов
В ответном сообщении о месте (proto) поле associatedCompounds идентифицирует соединения, связанные с этим местом. Сообщение о соединении содержит три типа информации:
- Тип соединения - один из четырех вариантов
-
compoundBuilding — отдельно стоящее здание, например, торговый центр или супермаркет. -
compoundSection — комплекс внутри более крупного комплекса, например, отдельный магазин в торговом центре. -
compoundGrounds — все, что связано с compoundBuilding , например, торговый центр, его парковка и любые другие здания в пределах этой парковки. -
unrecognized - значение по умолчанию
- Геометрия — координаты очерченного полигона, хранящиеся в структуре GeoJSON в поле
displayBoundary . Эти координаты используются для построения контура участка, здания или территории. - Входы - координаты широты и долготы всех расположенных входов и выходов.
Функция выбора местоположения возвращает любой составной тип, связанный с местоположением поиска. Если местоположение поиска находится в конкретном магазине в торговом центре, функция выбора местоположения возвращает: * конкретный магазин, его входы и выходы, а также его контур; * здание комплекса (торговый центр), его входы и выходы, а также его контур; * территорию комплекса (торговый центр + парковка), входы и выходы, а также контур всей территории.
На этом изображении показаны все три возвращаемых типа составных данных.
На этом изображении показаны несколько мест внутри аэропорта, а также границы как здания внутри аэропорта, так и границы аэропорта и всей прилегающей к нему территории.
