Ruby Gem Geocoder在Rails中为邮政编码提供了不正确的纬度值

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的代码：

Geocoder.search(60601).first.latitude

字符串
然而，这会导致9.42233953846154，这是不正确的。正确的值应该是41.something。所以它是错误的。
有没有更好的方法来获得准确的结果？

你应该试试，

Geocoder.search(60601)[1].latitude

字符串
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)

Geocoder.search（60601）.map（&：latitude）
它将显示列出的纬度数组，结果如下所示
[9.42233953846154，41.83832739698795，52.41794258392857]
你可以通过传递索引来选择你的纬度。
