Yakında Arama (Yeni), bir veya daha fazla yer türü alır ve eşleşen yerlerin listesini döndürür. Aşağıdaki örnekte bir yer türü seçip sonuçları haritada görebilirsiniz. Yerler hakkında daha fazla bilgi edinmek için işaretçileri tıklayın.
Yakında Arama (Yeni), belirttiğiniz yer türlerine (ör. restaurant, book_store veya bowling_alley) göre bir dizi yer hakkında bilgi döndürür. Hizmet, belirtilen locationRestriction yarıçapı içinde belirtilen yer türleriyle eşleşen yerlerin listesini döndürür.
Yakında Arama (Yeni) özelliğini kullanmak için Google Cloud projenizde "Places API (Yeni)" özelliğini etkinleştirmeniz gerekir. Ayrıntılar için Başlayın bölümüne bakın.
Yakındaki yerleri bulun
Belirtilen yer türlerine, konuma ve yarıçapa göre yerlerin listesini döndürmek için searchNearby() yöntemini çağırın. Bir istek kullanarak arama parametrelerini belirtin ve ardından searchNearby() yöntemini çağırın. Sonuçlar, yer ayrıntılarını alabileceğiniz Place nesnelerinin listesi olarak döndürülür.
Aşağıdaki snippet'te, bir istek ve searchNearby() çağrısı örneği gösterilmektedir:
TypeScript
// Get bounds and radius to constrain search. center = mapElement.center!; const ne = innerMap.getBounds()!.getNorthEast(); const sw = innerMap.getBounds()!.getSouthWest(); const diameter = spherical.computeDistanceBetween(ne, sw); const radius = Math.min(diameter / 2, 50000); // Radius cannot be more than 50000. const request = { // required parameters fields: [ 'displayName', 'location', 'formattedAddress', 'googleMapsURI', ], locationRestriction: { center, radius, }, // optional parameters includedPrimaryTypes: [typeSelect.value], maxResultCount: 5, rankPreference: SearchNearbyRankPreference.POPULARITY, }; const { places } = await Place.searchNearby(request);
JavaScript
// Get bounds and radius to constrain search. center = mapElement.center; const ne = innerMap.getBounds().getNorthEast(); const sw = innerMap.getBounds().getSouthWest(); const diameter = spherical.computeDistanceBetween(ne, sw); const radius = Math.min(diameter / 2, 50000); // Radius cannot be more than 50000. const request = { // required parameters fields: [ 'displayName', 'location', 'formattedAddress', 'googleMapsURI', ], locationRestriction: { center, radius, }, // optional parameters includedPrimaryTypes: [typeSelect.value], maxResultCount: 5, rankPreference: SearchNearbyRankPreference.POPULARITY, }; const { places } = await Place.searchNearby(request);
- Bir veya daha fazla veri alanının virgülle ayrılmış listesini belirtmek için
fieldsparametresini (gerekli) kullanın. - 50.000 metreye kadar bir yarıçap belirtmek için
locationRestrictionparametresini (zorunlu) kullanın. - Aranacak bir veya daha fazla yer türü belirtmek için
includedPrimaryTypesparametresini kullanın. POPULARITYveyaDISTANCESearchNearbyRankPreferencedeğerini belirtmek içinrankPreferenceparametresini kullanın.- Parametrelerin tam listesini inceleyin.
Örnek
Aşağıdaki örnekte, harita sınırları içinde seçilen türdeki yerleri sorgulamak için searchNearby() kullanılır ve sonuçları göstermek için harita işaretçilerle doldurulur.
