第一次node js循環(huán)使用荷荤，開始的時候還以為要等待第一個壓縮完成后循環(huán)第二個，結(jié)果我錯了古毛。
異步原來是這樣。
牛颖低！120文件手動壓縮蹬敲，估計要好久。程序太方便了，10秒就壓縮完了阱扬。
不過自己寫程序用了1個多小時。下次壓縮文件肯定可以用的到。

var fs = require('fs');
var archiver = require('archiver');
var path=__dirname;
var dirList = fs.readdirSync(path);
var status=true;
dirList.forEach(function(item){
console.log(item);
// create a file to stream archive data to.
var output = fs.createWriteStream('F:\\work\\wxapp\\input\\'+item+'.zip');
var archive = archiver('zip', {
zlib: { level: 9 } // Sets the compression level.
});
// listen for all archive data to be written
output.on('close', function() {
console.log(archive.pointer()/1024/1024 + 'M');
console.log('壓縮完成');
});
// good practice to catch this error explicitly
archive.on('error', function(err) {
status=false;
throw err;
});
// pipe archive data to the file
archive.pipe(output);
archive.directory(item+'/');
archive.finalize();
});
// append a file from stream
/*var file1 = __dirname + '/120個小程序源碼/AppleMusic';
archive.append(fs.createReadStream(file1), { name: 'AppleMusic' });*/
// append a file from string
/*archive.append('string cheese!', { name: 'file2.txt' });
// append a file from buffer
var buffer3 = new Buffer('buff it!');
archive.append(buffer3, { name: 'file3.txt' });
// append a file
archive.file('file1.txt', { name: 'file4.txt' });
// append files from a directory
archive.directory('subdir/');
// append files from a glob pattern
archive.glob('subdir/!*.txt');*/
// finalize the archive (ie we are done appending files but streams have to finish yet)
//archive.finalize();
