In my webpage, a user is supposed to upload a zipped file. Within the zipped file are 2 files: another zip file and a txt file. On my server, after receiving the zip, I want to unzip the zip file to extract the zip & txt file, then move those 2 files to a predefined folder. I have a piece of code that extracts the zip file, but the data doesn't seem correct. Firstly, it unzipped a zip and 2 txt file when there should only be 1 txt file. It created an additional 'undefined' txt file. Also, in my txt file, instead of the original data, it was replaced with the following text: '[undefined] [undefined]'.
Can anyone help me on this? The following is my code:
var JSZip = require('JSZip');
fs.readFile( filePath, function(err, data){
if (!err){
var zip = new JSZip();
JSZip.loadAsync(data).then(function(zip){
object.keys(zip.files).forEach(function(filename){
var content = zip.files[filename];
var dest = path + filename;
fs.writeFileSync(dest, content);
});
});
}
});
This is a working version I am using:
var jsZip = require('jszip')
jsZip.loadAsync(file).then(function (zip) {
Object.keys(zip.files).forEach(function (filename) {
zip.files[filename].async('string').then(function (fileData) {
console.log(fileData) // These are your file contents
})
})
})
You can get most of the information you need from http://stuk.github.io/jszip/documentation/examples.html but it's a little hard to get in one place, you have to look around a bit.
It took a bit of digging in their documentation but they have an example that shows how to read the file contents from a ZIP.
You are getting the object that describes the ZIP contents but not the actual content. Here is an adjusted version:
var JSZip = require('JSZip');
fs.readFile(filePath, function(err, data) {
if (!err) {
var zip = new JSZip();
zip.loadAsync(data).then(function(contents) {
Object.keys(contents.files).forEach(function(filename) {
zip.file(filename).async('nodebuffer').then(function(content) {
var dest = path + filename;
fs.writeFileSync(dest, content);
});
});
});
}
});
