Google Maps API（3.0）を初めて使用します。Maps APIへの方向クエリに基づいて途中降機都市を取得したいのですが、これまでのところ、この特定のトピックに関するドキュメントは見つかりませんでした。
https://developers.google.com/maps/documentation/javascript/directions#Steps
住所Aと住所Bに基づいて方向を取得しています。ユーザーが旅行中に横断するすべての都市を知りたいです。ウェイポイント（ストップオーバー）に関する情報をいくつか見つけましたが、これらはすべての停車地または通りの変更に関連しています。今のところコアオブジェクトが見つかりませんでした...
私がすること：
概念実証では、検索を行う場所の種類、距離、および領域を調整する必要があります。ルートの用途と長さによっては、道路に沿った一定の間隔（100メートルまたは1000メートル）のポイントで逆ジオコーダーを使用する方がよい場合があります。これにより、PlacesAPIが使用されなくなります。クォータ。
私はこれに対する代替の解決策を見つけました。HereMapsAndroidガイドまたは HereMapsAPIリクエストを使用して2つのポイントを使用して主要都市を取得でき ます。APIリクエストを使用しました
APIレスポンスで主要都市の経度と緯度を返します。そのデータから、GoogleAPIのジオコーダーを使用して都市名を見つけることができます
ここで、マップAPIリクエストURLは次のようになります。
https://route.api.here.com/routing/7.2/calculateroute.json ?app_id={YOUR_APP_ID} &app_code={YOUR_APP_CODE} &waypoint0=geo!52.5,13.4 &waypoint1=geo!52.5,13.45 &mode=fastest;car;traffic:disabled
応答：（route [0] .leg [0] .maneuverにはメインポントが含まれています）
