[英]Using NodeJS with AppJS to Package Zip with JSZip
My original file wouldn't download using the local method so I decided to use Node.js , as it's already packed in AppJS , and still the zip file won't execute in AppJS. 我的原始文件无法使用本地方法下载,所以我决定使用Node.js ,因为它已经打包在AppJS中 ,而zip文件仍然无法在AppJS中执行。
$(".export").on("click", function() { var fs = require("fs"); var JSZip = require("jszip"); var zip = new JSZip(); zip.file("hello.txt", "Hello node!"); var content = zip.generate({type:"nodebuffer"}); // saveAs(content, "test.zip"); fs.writeFile("test.zip", content, function(err) { if (err) throw err; }); });
body { background: #fff; }

Note: I've tried saving files using the File API, but the only want I've been able to successfully write a file in AppJS is by using Node.js as seen below. 注意:我曾尝试使用File API保存文件,但我唯一能够在AppJS中成功写入文件的方法是使用Node.js,如下所示。
var fs = require("fs");
fs.writeFile("hello.txt", "Hi", function(err) {
if (err) throw err;
});
I wasn't using Node but instead doing something similar in the browser that required FileSaver.js
as well. 我没有使用Node,而是在需要FileSaver.js
的浏览器中执行了类似的操作。
Have you tried: 你有没有尝试过:
var JSZip = require('jszip');
var saveAs = require('filesaver.js');
var zip = new JSZip();
zip.file("hello.txt", "Hello node!");
var blob = zip.generate({type: 'blob'});
saveAs(blob, 'images.zip');
The main difference here using {type: 'blob'}
instead of nodebuffer
. 这里的主要区别是使用{type: 'blob'}
而不是nodebuffer
。 I was successful setting the response type to arraybuffer
using a simple XHR download module. 我使用一个简单的XHR下载模块成功将响应类型设置为arraybuffer
。
module.exports = function download(url, callback) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'arraybuffer';
xhr.onload = function(e) {
callback(null, xhr.response);
};
xhr.onerror = function(e) {
callback(status.response);
};
xhr.send(null);
};
