怎么把js文件放到服务器,如何将文件上传到远程服务器并在nodejs中更改它的路径？...

var express = require('express')

, multiparty = require('multiparty')

, request = require('request')

, fs = require('fs')

, util = require('util')

, http = require('http');

var app = express();

app.use('/static', express.static('static'));

process.on('uncaughtException', function (err) {

console.log(err);

});

app.get('/', function (req, res) {

res.redirect('static/index.html');

});

app.post('/upload', function(req, res, next){

//https://github.com/request/request#streaming

var form = new multiparty.Form();

form.parse(req, function(err, fields, files) {

res.writeHead(200, {'content-type': 'text/plain'});

res.write('received upload:\n\n');

res.end(util.inspect({fields: fields, files: files}));

});

form.on('file', function(name, file) {

var formData = {

file: {

value: fs.createReadStream(file.path),

options: {

filename: file.originalFilename

}

}

};

console.log(formData)

// Post the file to the upload server

request.post({url: 'http://192.138.2.73:4000/upload', formData: formData});

});

});

var server = app.listen(3000, '0.0.0.0' ,function() {

var host = server.address().address;

var port = server.address().port;

console.log('Example app listening at http://%s:%s', host, port);

});

这是upload.js文件：

var express = require('express')

, multiparty = require('multiparty')

, cors = require('cors')

, util = require('util')

, app = express();

app.use(cors());

process.on('uncaughtException', function (err) {

console.log(err);

});

app.get('/', cors(), function(req, res, next){

res.json({msg: 'This is CORS-enabled for all origins!'});

});

app.post('/upload', cors(), function(req, res, next){

var form = new multiparty.Form();

form.parse(req, function(err, fields, files) {

res.writeHead(200, {'content-type': 'text/plain'});

res.write('received upload:\n\n');

res.end(util.inspect({fields: fields, files: files}));

});

form.on('file', function(name,file) {

// console.log(file);

// console.log(name);

});

});

app.listen(4000, function(){

console.log('CORS-enabled web server listening on port 4000');

});

我从一个系统上传我的文件到远程系统到另一个系统。文件被成功上传到另一个系统，因为我正在远程系统中运行我的upload.js，在我的系统中运行app.js，并且正在从我的系统上传我的文件。现在我的问题是我上传的所有文件都保存在远程系统'/ var/tmp'中，并且也保存在我的系统'/ var/tmp'中。我需要将此路径更改为我自己定义的路径，例如：/ var/www/html/myfolder。然后该文件不应该保存在我的系统中。
