使用Google Maps API（路线）获取中途停留城镇

google-mapsgoogle-maps-api-3directions

我对Google Maps API（3.0）还不熟悉。我想基于Maps API的方向查询获取途经城市，并且目前尚未找到任何有关此特定主题的文档。

https://developers.google.com/maps/documentation/javascript/directions#Steps

我正在根据A地址和B地址获取方向。我想知道用户在旅程中会经过哪些城市。我找到了一些关于途经点（停靠点）的信息，但这些只涉及每个停留或街道变化。目前为止，我还没有找到任何核心对象...

我的做法：

  1. 使用RouteBoxer查找包含路径的边界（较小的边界）
  2. 使用Places API返回城市大厅、地方政府办公室或图书馆等类型的地点（也许需要微调），位于这些边界内。
  3. 从这些响应中取出城镇数据，对其进行排序以获取唯一结果，然后使用它们。

概念证明，需要调整位置类型、距离和搜索区域。根据使用情况和路线长度，最好在路上的一些定期间隔点上使用反向地理编码器（100米或1000米），这可能更快，并且不会使用Places API配额。

添加了概念验证。 - geocodezip
这是一个很好的答案，但是如果要处理长路线问题，你会怎么做呢？比如从纽约到蒙特利尔，这是一段374英里的路程，途中几乎没有任何城市可以参考。把它分成374个一英里的点，并且对每个点使用反向地理编码器，这样可行吗？ - Eugene
这个概念验证对我从纽约到蒙特利尔都有效。这只是一个概念验证，如果您有其他限制/考虑因素，您可能需要进行修改。如果您对此有疑问，应该提出一个新问题。 - geocodezip
非常感谢您的帮助！我现在会详细研究它，看看是否可以用它来解决我的特定问题。我将关闭我的其他问题，并再次表示感谢！ - Eugene

我找到了一个替代方案。我们可以使用Here Maps Android Guide或Here Maps API request来获取两个点之间的主要城市。我使用了API请求。
API响应返回主要城市的经度和纬度。通过这些数据，我们可以使用Google API的Geocoder来查找城市名称。
Here maps API请求URL将会像这样：
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
