问题 - 人们根据他们的兴趣在各个地方张贴,而其他人则在更大的区域搜索帖子。 例如 - 用户A在悉尼郊区邦迪海滩下的帖子。 用户B在悉尼搜索帖子。
期望的结果 - 自Bondi位于悉尼境内后,用户B可以看到用户A的帖子。
解决方案:
在google places API中查找,它告诉您郊区X是Y市,依此类推。 在我的例子中 - 我想获得有关邦迪的信息,告诉我它属于哪个城市。
这是我对Bodni Beach的简单查询(我使用auto complete因为它是一个自动完成下拉列表): https://maps.googleapis.com/maps/api/place/autocomplete/json?sensor=true&input=bondi%20beach&key=myKey

正如你所看到的,唯一告诉我邦迪是悉尼一部分的结果是“邦迪海滩景观”,它没有意义,也没有帮助解决我的问题。
我在世界各地的许多其他地方遇到过这个问题。
如何获得场所层次结构的准确信息?
答案 0 :(得分:7)
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,获取一个地方的坐标(你可以在自动完成结果中找到place_id):
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,Bondi Beach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一个)。
我希望,我的回答至少会对你有所帮助。
答案 1 :(得分:0)
你可以
console.log(places.address_components)
然后使用检查浏览器上的控制台。
它将显示访问所需信息所需的层次结构和键。郊区/社区应显示为
'sublocality_level_1'
