vue3 下载图片（包括多图片下载）

单图片下载

//使用
download('https://img1.baidu.com/it/u=1493209339,2544178769&fm=253&app=138&size=w931&n=0&f=JPEG&fmt=auto?sec=1715101200&t=854f3434686cfd2cba9d6a528597d15c')//下载逻辑
const download = async (modelUrl) => {const response = await fetch(modelUrl);// 将响应体转换为Blobconst blob = await response.blob();// 创建隐藏的a标签来触发下载const link = document.createElement('a');link.href = URL.createObjectURL(blob);link.download = 'image.jpg'; // 自定义下载的文件名link.click();document.body.removeChild(link); // 下载后移除元素
}

多图片打包下载
安装yarn add jszip 或 npm i jszip
yarn add file-saver 或 npm i file-saver

import JSZip from "jszip"
import { saveAs } from 'file-saver'
const imgList = ref([{ id: 1, url: 'https://img1.baidu.com/it/u=1493209339,2544178769&fm=253&app=138&size=w931&n=0&f=JPEG&fmt=auto?sec=1715101200&t=854f3434686cfd2cba9d6a528597d15c' }, { id: 2, url: 'https://img1.baidu.com/it/u=3714509592,1056938510&fm=253&app=138&size=w931&n=0&f=JPEG&fmt=auto?sec=1715101200&t=855f002cda64244524d6945999b0be2a' }])
const downloadImg = async () => {const imageUrls = []; // 替换为实际的图片URL数组const filenames = []; // 对应的文件名数组arr.forEach(ii => {imageUrls.push(ii.url)filenames.push((ii.name || ii.id) + '.png')})createAndDownloadImageZip(imageUrls, filenames);
