Beispiele

In diesem Abschnitt finden Sie eine Reihe von Beispielanfragen an die Places Aggregate API.

Clientbibliothek installieren

Wenn Sie die Python-Beispiele (gRPC) verwenden möchten, müssen Sie die spezifische Clientbibliothek für die Places Aggregate API und die Google Auth-Bibliothek installieren:

pip install google-maps-areainsights google-auth

Orte innerhalb eines Kreises zurückgeben

Gib alle Restaurants in einem Umkreis von 200 m um den Trafalgar Square in London zurück.

  • Der Suchbereich ist ein Kreis, dessen Mittelpunkt ein bestimmter Längen- und Breitengrad ist. Der Radius dieses Kreises beträgt 200 Meter, was die Größe des Suchbereichs bestimmt.
  • Der angeforderte Ortstyp ist „restaurant“. Dieser wird mit includedTypes in typeFilters übergeben.
  • Die Anzahl wird mit INSIGHTS_COUNT und die Orts-IDs werden mit INSIGHTS_PLACES angefordert.

Ortstypen ausschließen

Sie können Ortstypen von der Zählung ausschließen.

Die folgende Anfrage ist mit der im ersten Beispiel identisch, fügt aber excludedTypes zu typeFilters hinzu. Sie können für includedTypes und excludedTypes entweder einen String oder ein Array von Strings verwenden.

In diesem Beispiel werden zwei Ortstypen, cafe und bakery, von der Anzahl der restaurant ausgeschlossen.

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 Bereiche beschränkt, die klein genug sind, um bis zu 100 Orts-IDs zurückzugeben. Verwenden Sie für größere Gebiete INSIGHTS_COUNT, um diese Einschränkung zu umgehen, damit der Dienst keine einzelnen Orts-IDs zurückgeben muss.

Wie zuvor wird der Ortstyp restaurant verwendet. In diesem Beispiel werden auch drei weitere Filter vorgestellt:

  • operatingStatus: In diesem Beispiel werden nur geöffnete Orte gezählt.
  • priceLevel: In diesem Beispiel werden nur günstige und mäßig teure Orte gezählt.
  • ratingFilter: In diesem Beispiel werden nur Orte mit einer Bewertung zwischen 4,0 und 5,0 gezählt.

Geografischer Bereich

In diesem Beispiel wird die Orts-ID eines geografischen Gebiets verwendet, um den Suchbereich festzulegen. Diese Orts-IDs enthalten die Geometrie eines Ortes, z. B. einer Stadt. Die hier verwendete Orts-ID ist ChIJiQHsW0m3j4ARm69rRkrUF3w, was 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 Bereichs festgelegt. Die Orts-ID wird mit place im Format places/place_ID übergeben.

Sie haben folgende Möglichkeiten, die Orts-ID eines geografischen Gebiets abzurufen:
