nodejs如何实现zip压缩和zip解压,下面web建站小编给大家详细介绍一下实现代码!
zip压缩代码:
// require modules var fs = require("fs"); var archiver = require("archiver"); // create a file to stream archive data to. var output = fs.createWriteStream(__dirname + "/example.zip"); var archive = archiver("zip", { zlib: { level: 9 }, // Sets the compression level. }); // pipe archive data to the file archive.pipe(output); // append a file from stream var file1 = __dirname + "/file1.txt"; archive.append(fs.createReadStream(file1), { name: "file1.txt" }); // append a file from string archive.append("string cheese!", { name: "file2.txt" }); // append a file from buffer var buffer3 = Buffer.from("buff it!"); archive.append(buffer3, { name: "file3.txt" }); // append a file archive.file("file1.txt", { name: "file4.txt" }); // append files from a sub-directory and naming it `new-subdir` within the archive archive.directory("subdir/", "new-subdir"); // append files from a sub-directory, putting its contents at the root of archive archive.directory("subdir/", false); // append files from a glob pattern archive.glob("subdir/*.txt"); archive.finalize();
zip解压代码:
var fs = require("fs"); var unzip = require("unzip"); fs.createReadStream("archiver-unzip.zip").pipe( unzip.Extract({ path: "unarchive" }) );
