[英]how to create a zip file in node given multiple downloadable links
I have a node application that contains several downloadable links (when you click on the link a pdf file is downloaded), and these links are dynamically created/populated.我有一个包含几个可下载链接的节点应用程序(当您单击链接时,会下载 pdf 文件),并且这些链接是动态创建/填充的。 I want to implement a feature where we can somehow download all files from these links in one go.
我想实现一个功能,我们可以以某种方式从一个 go 中的这些链接下载所有文件。 I presume for this I will somehow need to create a zip file from all these links - would anyone know how to go about this?
我想为此我会以某种方式需要从所有这些链接创建一个 zip 文件 - 有人知道如何 go 吗?
you could use the fs and archiver module:您可以使用 fs 和归档器模块:
var fs = require('fs');
var archiver = require('archiver');
var output = fs.createWriteStream('./example.zip');
var archive = archiver('zip', {
gzip: true,
zlib: { level: 9 } // Sets the compression level.
});
archive.on('error', function(err) {
throw err;
});
// pipe archive data to the output file
archive.pipe(output);
// append files
archive.file('/path/to/file0.txt', {name: 'file0-or-change-this-whatever.txt'});
archive.file('/path/to/README.md', {name: 'foobar.md'});
//
archive.finalize();
