的解压与目录结构的zip文件内袋
var Zip = require('machinepack-zip');
//解压缩指定的.zip文件和写解压缩的文件/目录作为指定的目标目录的内容。
Zip.unzip({
source: '/Users/mikermcneil/stuff.zip',
destination: '/Users/mikermcneil/my-stuff',
}).exec(callbackSuccess, callbackFail);
下载远程文件并解压您可以使用此代码：
var fs = require('fs');
var unzip = require("unzip2");
var tar = require('tar');
var zlib = require('zlib');
var path = require('path');
var mkdirp = require('mkdirp'); // used to create directory tree
var request = require("request");
var http = require('http');
var zip = require("machinepack-zip");
for (var i = 0; i < _diff.length; i++) {
request(constants.base_patch +"example.zip")
request = http.get({ host: 'localhost',
path: '/update/patchs/' + "example.zip",
port: 80,
headers: { 'accept-encoding': 'gzip,deflate' } });
request.on('response', (response) => {
var output = fs.createWriteStream(__dirname + "/tmp/" +"example.zip");
switch (response.headers['content-encoding']) {
// or, just use zlib.createUnzip() to handle both cases
case 'gzip':
response.pipe(zlib.createGunzip()).pipe(unzip.Extract({ path: __dirname }));
break;
case 'deflate':
response.pipe(zlib.createInflate()).pipe(unzip.Extract({ path: __dirname }));
break;
default:
response.pipe(output);
break;
}
})
request.on('close', function(){
zip.unzip({
source: __dirname + "/tmp/" + "example.zip",
destination: __dirname,
}).exec({
error: function (err){
alert("error")
},
success: function(){
//delete temp folder content after finish uncompress
},
});
})
}
注：去掉unnecesary模块。
