前言
目前大部分定位都是依赖获取经纬度并向相关 API 调用以获取人类可读的名称的。
推荐的地图 API 平台：高德开放平台
Where? / 甘肃省兰州市榆中县小康营乡潘家庄在哪？
根据地图指引，该地区为 北纬 35.86166 东经 104.195397 划重点，要考
Why? / 为什么我的定位会这样？
由于部分浏览器的缘故，无法定位到准确的地址，所以偏差较大
通过这篇文章我猜测你已经知道了问题所在：https://www.cnblogs.com/xingxiudong/archive/2010/07/29/3987005.html，还是不知道？请继续阅读。
What? / What the f**k？
浏览器内部使用一个底层 API 来获取经纬度，而操作系统没有允许获取精确地址的时候，浏览器会按照一个表返回对应国家的经纬度。还记得我们上面提到的那个经纬度吗？参照文章得出这就是中国的经纬度。浏览器没有获取到准确的地址，就返回了一个大致的国家位置。
How? / 怎么解决定位不精确？
可以在操作系统的设置中允许浏览器进行精确定位
