javascript - 如何导航并获取 URL 中的特定 json 对象？

Question

我从 url 获取 json，但它有很多对象，我如何才能只获取给出下面提供的 json 的 slugs？

我不介意在 php 或 js 中使用它，我的意思是一方面我需要知道如何使用 php 或 js 获取我想要的对象，另一方面我想知道我们是否可以获取一个对象在 url 中提供参数

我如何获得所有“slug”:”的列表，其值如网址中的“slug”:“amici”？

在 JavaScript 中，您可以使用 Array.prototype.map() 和解构赋值

let res = data.map(({slug}) => slug)
