Pythonを使用してDirections APIを使用しています。
mapApi = GoogleMaps(API_KEY)
directionsObj.routes = mapApi.directions(directionsObj.source, directionsObj.destination)
print "directionsObj.routesssss", directionsObj.routes['routes']
上記のコードを使用して、Directions API の Json 応答ファイルを取得し、Json を mongoengine (使用するデータベース) に保存しました。ターミナルで上記のコードを実行すると、次の結果が得られます。
