嘉兴做网站网站建设基本标准

关于多张图片上传或者下载显示报错后会程序会终止执行，从而影响后面图片上传。

解决方法：

/*能正常访问的图片*/
const url = 'https://2vimg.hitv.com/100/2308/0109/5359/dqKIZ7d4cnHL/81Vu0c.jpg?x-oss-process=image/format,webp';
/*不能正常下载的图片 （跨域问）*/
const urls = 'https://p26-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/36b749b8bc954816b90998beef6a93e5~noop.image?_iz=58558&from=article.pc_detail&x-expires=1691135481&x-signature=ohziADdEWZ1qrfRqUI6xIitOnVk%3D';(function () {fetchFile(url, 'image');fetchFile(urls, 'images');})()async function fetchFile(url, fileName) {let promise = new Promise(async function (resolve, reject) {// try {await fetch(url).then((response) => response.blob()).then((blob) => {const file = new File([blob], fileName, {type: blob.type, lastModified: Date.now()})resolve(file);}).catch(error => reject(error))// } catch (e) {//     reject(e)// }})promise.then(/*请求成功*/function resolve(file) {const box = document.getElementsByClassName('box1')box[0].src = URL.createObjectURL(file);console.log(file)},/*请求失败报错*/function reject(error) {const box = document.getElementsByClassName('box')box[0].src = 'https://1vimg.hitv.com/100/2307/2810/1525/2WZw3cbDPP/bjgE99.jpg?x-oss-process=image/format,webp'console.log("报错设置默认图片")console.log(error)})
