nodejs压缩成7z_nodejs如何压缩和解压缩zip文件?

var AdmZip = require(‘adm-zip’);

// reading archives

var zip = new AdmZip("./my_file.zip");

var zipEntries = zip.getEntries(); // an array of ZipEntry records

zipEntries.forEach(function(zipEntry) {

console.log(zipEntry.toString()); // outputs zip entries information

if (zipEntry.entryName == "my_file.txt") {

console.log(zipEntry.data.toString('utf8'));

}

});

// outputs the content of some_folder/my_file.txt

console.log(zip.readAsText("some_folder/my_file.txt"));

// extracts the specified file to the specified location

zip.extractEntryTo(/*entry name*/"some_folder/my_file.txt", /*target path*/"/home/me/tempfolder", /*maintainEntryPath*/false, /*overwrite*/true);

// extracts everything

zip.extractAllTo(/*target path*/"/home/me/zipcontent/", /*overwrite*/true);

// creating archives

var zip = new AdmZip();

// add file directly

zip.addFile("test.txt", new Buffer("inner content of the file"), "entry comment goes here");

// add local file

zip.addLocalFile("/home/me/some_picture.png");

// get everything as a buffer

var willSendthis = zip.toBuffer();

// or write everything to disk

zip.writeZip(/*target file name*/"/home/me/files.zip");
