Делаю загрузку файлов на сервер. Хочу использовать потоки.
Я попытался кое-что сделать:
//FileSystem handler library
var log = require("core/lib/log")(module);
var fs = require('fs');
var async = require('async');
var fsh = function (files) {
var $this = this;
this.moveUploadedFiles = function(dest,cb){
if(!Object.keys(files).length){
log.info('fsh.moveUploadedFiles-> files object is empty');
return cb({state:0}); //files not found
}
async.waterfall ([
function (cb) {
$this.createFolder(dest,function(){
cb(null);
});
}
], function () {
var infile = [];
var outfile = [];
var uploadSize = [];
for (var i in files) {
var path = dest + '/' + files[i].originalFilename;
infile[i] = fs.createReadStream(files[i].path);
outfile[i] = fs.createWriteStream(path);
infile[i].on('data',function(data) {
if(!uploadSize[i]){
uploadSize[i] = 0;
}
uploadSize[i] += data.length/1024;
console.log(files[i].originalFilename + ': '+(files[i].size/1024) + '/'+uploadSize[i]+' Kb');
outfile[i].write(data);
});
infile[i].on('close', function() {
outfile[i].close();
});
infile[i].pipe(outfile[i]);
}
});
return cb({state:1}); //upload success
};
this.createFolder = function(dir,cb){
fs.exists(dir, function (exists) {
if(exists){
log.info('fsh.createFolder-> Dir exist: %s',dir);
return cb();
}else{
fs.mkdir(dir,777,function(){
log.info('fsh.createFolder-> %s',dir);
return cb();
});
}
});
};
};
module.exports = fsh;
но как-то неправильно работает, несколько файлов за раз не пишет, работает только с одним. Я выбрал два разных файла, в консоли вижу следующее:

В чем может быть проблема?
