json - Google 放置 API 层次结构 - 街区/郊区 -> 城市 -> 地区 -> 国家

Question

问题 -
人们根据自己的兴趣在不同的地方发帖，而其他人则在更大的领域搜索帖子。
例如- 用户 A 在悉尼郊区邦迪海滩 (Bondi Beach) 下发帖。
用户 B 在悉尼下搜索帖子。
预期结果 - 用户 B 可以看到用户 A 的帖子，因为 Bondi 位于悉尼内。
解决方案:
在 Google 位置 API 中查找它告诉您郊区 X 属于城市 Y 等等。
在我的例子中 - 我想获得关于邦迪的信息，告诉我它属于哪个城市。
这是我对邦迪海滩的简单查询(我使用自动完成，因为它是一个自动完成下拉菜单):

如您所见，唯一告诉我邦迪是悉尼一部分的结果是“邦迪海滩景观”，这没有任何意义，也无助于解决我的问题。
我在世界各地的许多其他地方都遇到过这个问题。
如何获得地点层次结构的准确信息？

Answer 1

我有类似的问题。我做了一些研究，但没有找到准确的解决方案。目前我正在使用以下解决方法，这对我的情况来说已经足够了。

首先，获取一个地点的坐标(place_id 你可以在自动完成结果中找到):

https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJWTi8xgGyEmsRgK0yFmh9AQU&key=yourKey

之后，使用这些坐标和所需的 result_types 执行反向地理编码请求: country, administrative_area_level_1, administrative_area_level_2, locality .

例如:

https://maps.googleapis.com/maps/api/geocode/json?latlng=-33.8914755,151.2766845&result_type=locality&key=yourKey

这不是 100% 准确的方法。它为某些位置提供了多个结果(如您所见，邦迪海滩就是其中之一)，但您可以尝试通过其他一些属性选择一个(在这种情况下， colloquial_area 类型的结果是正确的) .

我希望，我的回答至少能对你有所帮助。
