具體實現(xiàn)

1、安裝相關(guān)依賴

npm install file-saver
npm install jszip

2、參考源碼

/**
 * 多文件打包并下載
 * @param files 待下載的文件列表
 * @param filename  下載的目標文件名
 */
const download = (files, filename) => {
  let zip = new JSZip();
  let folder = zip.folder('files');
  Promise.resolve().then(() => {
    return files.reduce((accumulator, file) => {
      return accumulator.then(() => fetch(file.url)
                        .then(resp => resp.blob())
                        .then(blob => folder.file(file.name, blob)))
    }, Promise.resolve())
  }).then(() => {
    folder.generateAsync({type: "blob"}).then(content => saveAs(content, filename));
  })
}

3、測試

const files = [
  {name: 'antd.css', url: 'https://cdn.bootcdn.net/ajax/libs/antd/4.12.3/antd.css'},
  {name: 'antd.js', url: 'https://cdn.bootcdn.net/ajax/libs/antd/4.12.3/antd.js'}
]

download(files, 'antd.zip');
