});
let downloadFileList = []
downloader.on(Callbacks.CHANGE, (file, fileList) => {
downloadFileList = [...fileList]
});
downloader.on(Callbacks.SUCCESS, (file, fileList) => {
console.log('Successful', file.link)
window.open(file.link)
});
downloader.on(Callbacks.FAILED, (file, fileList) => {
console.log("Failed !!!!!!", file, fileList);
});
downloader.on(Callbacks.PROGRESS, (file, fileList) => {
console.log('progress', file.progress, fileList)

const hanldeDownload = () => downloader.start('711.jpg');
// 重试
const handleRetry = (file) => file.retry();
// 暂停
const hanlePause = (file) => file.pause();
