谷歌地理位置地址搜索返回相同的搜索结果,partial_match = true



我正在使用以下请求(使用我的谷歌API密钥(调用谷歌地方地图API:

https://maps.googleapis.com/maps/api/geocode/json?address=32/36+Nagle+St,+Liverpool+NSW&components=postal_code:2170|国家:AU&key={your key}

它返回以下 JSON:

为什么当地址

作为相同的结果"部分匹配"地址传入时,结果在这里有 partial_match = true?

"partial_match" : true
我相信

这可能是因为结果是插值的,它不是来自 Google 数据库的功能,位置是根据插值计算的。

查看响应中的地点 ID。

通常,这些长位置 ID 对应于插值,结果是猜测的,我的假设是 API 在这种情况下设置部分匹配标志。

可以在Google数据库中找到的功能通常具有较短的地点ID。 ChIJARdFFWLRhIARK6RIUxEbJ30 .
