将zip文件解压缩到本地文件夹 [英] Extract zip file to local folder
问题描述
我的节点应用程序有来自客户端的快递和即时发送请求,如邮递员,我需要从 req 获取文件并将其解压缩到我的本地文件夹,我该怎么做?
我发现以下开源但不知道如何使用 req body
并将其解压缩到我的本地文件夹中,如C: //测试// extractDest,
以下代码取自以下开源,但如果是其他良好的开源,我可以使用它相反
我建议你使用
I have node app with express and im sending request from client like postman and I need to get the file from the req and extract it on my local folder,how I can do that ?
I found the following open source but not sure how to take the req body and extract it in my local folder like "C://Test//extractDest",
The code below is taken from the following open source but if there is other good open source for this I can use it instead https://www.npmjs.com/package/decompress-zip
var DecompressZip = require('decompress-zip');
var unzipper = new DecompressZip(filename)
unzipper.on('error', function (err) {
console.log('Caught an error');
});
unzipper.on('extract', function (log) {
console.log('Finished extracting');
});
unzipper.on('progress', function (fileIndex, fileCount) {
console.log('Extracted file ' + (fileIndex + 1) + ' of ' + fileCount);
});
unzipper.extract({
path: "C://Test//extractDest",
filter: function (file) {
return file.type !== "SymbolicLink";
}
});
This is how I send the zip file I simply select binary and choose a zip file
I'd recommend you using multer which works with multipart/form-data
content-type.
Here's a basic working example. It assumes we are only uploading a single file, a folder named "uploads" exists at the root of your project and a form field named "singleFileUpload" to hold your data. You can change all those following the multer documentation:
var path = require("path");
var express = require("express");
var multer = require("multer");
var Unzipper = require("decompress-zip");
var app = express();
app.use(multer({dest:'./uploads/'}).single('singleFileUpload'));
app.post("/", function(req, res){
if (req.file){
var filepath = path.join(req.file.destination, req.file.filename);
var unzipper = new Unzipper(filepath);
unzipper.on("extract", function () {
console.log("Finished extracting");
});
unzipper.extract({ path: "C://Test//extractDest"});
}
res.status(204).end();
});
app.listen(3000);
Using postman you can now upload and decompress files with this configuration:
