Nearby Search (nueva) toma uno o varios tipos de lugar y muestra una lista de lugares coincidentes.
Nearby Search (nueva) muestra información sobre un conjunto de lugares correspondientes al tipo de lugar que especificas (por ejemplo, restaurant
, book_store
o bowling_alley
. El servicio responde con una lista de lugares que coinciden con los tipos de lugar especificados según el radio de locationRestriction
.
Para utilizar Nearby Search (nuevo), debes habilitar "API de Places (nueva)" en tu proyecto de Google Cloud. Consulta Cómo comenzar para obtener información detallada.
Encuentra lugares cercanos
Llama a searchNearby()
para obtener una lista de lugares según los tipos de lugar, la ubicación y el radio. Especifica parámetros de búsqueda por medio de una solicitud y, luego, llama a searchNearby()
. Los resultados se muestran como una lista de objetos Place
que contienen detalles del lugar.
En el siguiente fragmento, se muestra un ejemplo de una solicitud y una llamada a searchNearby()
:
TypeScript
// Restrict within the map viewport. let center = new google.maps.LatLng(52.369358, 4.889258); const request = { // required parameters fields: ['displayName', 'location', 'businessStatus'], locationRestriction: { center: center, radius: 500, }, // optional parameters includedPrimaryTypes: ['restaurant'], maxResultCount: 5, rankPreference: SearchNearbyRankPreference.POPULARITY, language: 'en-US', region: 'us', }; //@ts-ignore const { places } = await Place.searchNearby(request);
JavaScript
// Restrict within the map viewport. let center = new google.maps.LatLng(52.369358, 4.889258); const request = { // required parameters fields: ["displayName", "location", "businessStatus"], locationRestriction: { center: center, radius: 500, }, // optional parameters includedPrimaryTypes: ["restaurant"], maxResultCount: 5, rankPreference: SearchNearbyRankPreference.POPULARITY, language: "en-US", region: "us", }; //@ts-ignore const { places } = await Place.searchNearby(request);
- Utiliza el parámetro
fields
(obligatorio) para especificar una lista separada por comas de uno o varios campos de datos. - Usa el parámetro
locationRestriction
(obligatorio) para especificar un radio de hasta 50,000 metros. - Usa el parámetro
includedPrimaryTypes
para especificar uno o varios tipos de lugar para buscar. - Usa el parámetro
rankPreference
para especificar unaSearchNearbyRankPreference
dePOPULARITY
oDISTANCE
. - Consulta la lista completa de parámetros.
Ejemplo
En el siguiente ejemplo, se usa searchNearby()
para buscar restaurantes en un radio de 500 metros desde el centro y se propagan marcadores en el mapa para mostrar los resultados.
