Ruby Gem Geocoder 在 Rails 中给出了错误的邮政编码纬度值

Question

我正在使用 Rails 对邮政编码进行地理编码。作为测试，我使用了邮政编码 60601 上的代码：

Geocoder.search(60601).first.latitude

但是，这会导致

9.42233953846154

，这是不正确的。正确的值应该是 41.something。所以还差得远呢

有没有更好的方法来获得准确的结果？

Answer 1

你应该尝试一下，

 Geocoder.search(60601)[1].latitude

因为这个特定的“60601”邮政编码在地球上有多个位置，所以你需要从这里的哈希中找到一个特定的地址，当你搜索 60601 时，你可以检查那里总共有 3 个位置。

Geocoder.search(60601)
