如何访问JSON API响应中的嵌套信息？

Question

我正在尝试构建一个简单的CLI加密货币跟踪器应用程序。该应用程序执行成功的API调用并返回以下响应：[ { exchange: 'binance',    base: 'ADA',    quote: 'BTC',    price_quote: '0.00001663',    timestamp: '2019-04-08T16:36:00Z' },  { exchange: 'binance',    base: 'ADX',    quote: 'BTC',    price_quote: '0.00003316',    timestamp: '2019-04-08T16:35:00Z' },...]如何访问响应中的特定对象？例如，如何将整个对象返回到哪里base: 'ADA？这是返回JSON响应的简单Axios调用：axios.get("https://api.nomics.com/v1/exchange-markets/prices?key=" + apiKey + "&currency=BTC&exchange=binance")    .then(function (response) {      console.log(response.data)    })

您可以使用查找

let response = [ { exchange: 'binance',base: 'ADA',quote: 'BTC',price_quote: '0.00001663',timestamp: '2019-04-08T16:36:00Z' },

{exchange: 'binance', base: 'ADX',quote: 'BTC',price_quote: '0.00003316',timestamp: '2019-04-08T16:35:00Z' },]

let value = response.find(e => e.base === 'ADA')

console.log(value)
