在JavaScript中从IP地址获取位置的方法

在本教程中，我们将学习如何使用JavaScript从一个IP地址中获取位置。

考虑一下，我们有以下的IP。

const ip = "112.39.244.19";

现在，我们需要通过上述地址来获取位置。

使用ipstack.com

为了从一个IP地址获取位置，我们需要通过传递用户的IP地址来调用api.ipstack.com api。

下面是一个例子。

const ip = "112.39.244.19";

fetch(`https://api.ipstack.com/${ip}?access_key = ${YOUR_ACCESS_KEY}`).
then(res=>res.json()).
then(data=> console.log(data.country_name));

输出。

"United states"

ipstack api包含与用户ip地址有关的各种属性。
