React-tsx-下载 Zip 格式的多个图像文件
React-tsx-Download Multiple image file in Zip format
我想下载包含多个图像的 zip,我使用 js-zip 但它不允许我使用 jszip-util 它的显示找不到名称 JSZipUtils 因为我认为是我的 TSX 文件。这是我试过的一些代码..
import * as React from 'react';
import JSZip from 'jszip';
import FileSaver from 'file-saver';
class ZipDemo extends React.Component{
download =()=>{
let links:string[]=[
"https://sequenceimagestaging.blob.core.windows.net/retouch/3xl/100/1610004/one.jpg?v=1569588865599",
"https://sequenceimagestaging.blob.core.windows.net/retouch/3xl/900/2411015/two.jpg?v=1569588865599",
"https://sequenceimagestaging.blob.core.windows.net/retouch/l/200/3310029/three.jpg?v=1569588865599",
"https://sequenceimagestaging.blob.core.windows.net/retouch/m/300/3237036/four.jpg?v=1569588865599",
"https://sequenceimagestaging.blob.core.windows.net/retouch/s/400/5372009/five.jpg?v=1569588865599"
];
var zip = new JSZip();
var count = 0;
var zipFilename = "Pictures.zip";
links.forEach(function (url, i) {
var filename = links[i];
filename = filename.replace(/[\/\*\|\:\<\>\?\"\]/gi, '').replace("httpssequenceimagestaging.blob.core.windows.netretouch","");
JSZipUtils.getBinaryContent(url, function (err, data) {
if (err) {
throw err;
}
zip.file(filename, data, { binary: true });
count++;
if (count == links.length) {
zip.generateAsync({ type: 'blob' }).then(function (content) {
FileSaver.saveAs(content, zipFilename);
});
}
});
});
}
render() {
return (
<div>
<button onClick={this.download}>click me </button>
</div>
);
}
}
export default ZipDemo;
我参考了jsfiddle
JSZipUtils 似乎是一个单独的项目,也需要导入。尝试 https://www.npmjs.com/package/jszip-utils?
let blob = fetch(url).then(r => r.blob());
zip1.file(filename, blob, { binary: true });
在
的 space 中添加这 2 行
JSZipUtils.getBinaryContent(url, function (err, data) {
if (err) {
throw err;
}
zip.file(filename, data, { binary: true });
它工作得很好,因为 jszip-utils 模块在打字稿中不可用我想我不确定,所以它是将文件转换为二进制文件的替代方法。
