通过Promise.all实现Promise.any

import axios from 'axios'
const urls = [url1, url2, url3]

const ajaxUrls = urls.map(url => {
  return new Promise((resolve, reject) => {
    axios
      .get(url)
      .then(res => reject(res))
      .catch(err => resolve(err))
  })
})

Promise
  .all(ajaxUrls)
  .then(err => {
    // 错误处理的代码
  })
  .catch(res => {
    // 处理 正常数据
  })
