javascript - 如何将 axios 响应数据添加到数组中

Question

我正在尝试将 URL 数组异步发送到缩短 URL 并将响应写入新数组的 API，我的问题是:

如何在所有 promise 都 resolve 之后执行某些事情？

我的代码

linkList = ['https://www.link1.com', 'https://www.link2.com'];
adsList = []
let ads = async () => {
    const req = axios(apiUrl + linkList)
    const res = await Promise.resolve(req)
    adLinks.push(res.data.shortenedUrl)
    console.log(adsList)
    // Here, it shows a updated array everytime a promise is resolved
}
ads()
console.log(adsList) // Returns [], because the promises aren't resolved by the time it runs

我希望在 adsList 中有一组缩短的 URL

Answer 1

我猜 axios 实际上是您的异步​​请求，在这种情况下，这应该是您获取缩短网址列表所需的全部内容:

const linkList = ['https://www.link1.com', 'https://www.link2.com'];
const adsList = await Promise.all(
  linkList.map(url => 
    axios(apiUrl + url).then(({data: shortenedUrl}) => shortenedUrl)
  )
);
