In diesem Abschnitt finden Sie eine Reihe von Beispielanfragen an die Places Aggregate API.
Orte innerhalb eines Kreises zurückgeben
Gibt alle Restaurants im Umkreis von 200 Metern um den Trafalgar Square in London zurück.
- Der Suchbereich ist ein Kreis, dessen Mittelpunkt auf einem bestimmten Breiten- und Längengrad liegt. Der Radius dieses Kreises beträgt 200 Meter, was die Größe des Suchbereichs bestimmt.
- Der angeforderte Ortstyp ist „Restaurant“ und wird mit
includedTypes
innerhalb vontypeFilters
übergeben. - Die Anzahl wird mit
INSIGHTS_COUNT
angefordert und die Orts-IDs mitINSIGHTS_PLACES
.

Ortstypen ausschließen
Sie können Ortstypen aus der Zählung ausschließen.
Die folgende Anfrage entspricht dem ersten Beispiel, aber es wird excludedTypes
zu typeFilters
hinzugefügt. Für includedTypes
und excludedTypes
können Sie entweder einen String oder ein Array von Strings verwenden.
In diesem Beispiel werden zwei Ortstypen, cafe
und bakery
, aus der Anzahl der restaurant
ausgeschlossen.

Primären Typ verwenden
In diesem Beispiel wird die Anfrage aus dem ersten Beispiel so geändert, dass nur Orte mit einem primaryType
von restaurant
in der Anzahl berücksichtigt werden.

Benutzerdefiniertes Polygon
In diesem Beispiel wird gezeigt, wie Sie ein benutzerdefiniertes Polygon verwenden, um Ihren Suchbereich zu definieren. Wenn Sie INSIGHTS_PLACES
angeben, wird die Suche auf Gebiete beschränkt, die klein genug sind, um bis zu 100 Orts-IDs zurückzugeben. Bei größeren Gebieten können Sie INSIGHTS_COUNT
verwenden, um diese Einschränkung zu umgehen. Der Dienst muss dann keine einzelnen Orts-IDs zurückgeben.
Wie bisher wird der Ortstyp restaurant
verwendet. In diesem Beispiel werden auch drei weitere Filter eingeführt:
operatingStatus
: In diesem Beispiel werden nur betriebsbereite Orte gezählt.priceLevel
: In diesem Beispiel werden nur preiswerte und mäßig teure Orte berücksichtigt.ratingFilter
: In diesem Beispiel werden nur Orte mit einer Rezensionsbewertung zwischen 4,0 und 5,0 gezählt.

Geografischer Bereich
In diesem Beispiel wird eine Orts-ID vom Typ Geographical Area verwendet, um den Suchbereich festzulegen.
Diese Orts-IDs enthalten die Geometrie eines Orts, z. B. einer Stadt. Die hier verwendete Orts-ID ist ChIJiQHsW0m3j4ARm69rRkrUF3w
, die der Stadt Mountain View, Kalifornien entspricht.
Wenn Sie die Orts-ID an die Places Aggregate API übergeben, wird der Suchbereich auf die Grenzen des geografischen Gebiets festgelegt. Die Orts-ID wird mit place
im Format places/place_ID
übergeben.
Sie haben folgende Möglichkeiten, eine Orts-ID für ein geografisches Gebiet zu erhalten:
- Orts-ID-Suche
- Geocoding API
- Textsuche (Neu)
- Nearby Search (New)
- Address Validation API
- Place Autocomplete
