How it works

Dotload reads files from local hard disk, post the formdata built by rfc rules to the remote server. Data will be parsed and saved to the disk as files. All you need is a config.js

Simple Form Type

#First boundary
--<boundary><crlf>
# Field1
Content-Disposition:form-data; name="<fieldname1>"<crlf><crlf>
<value1><crlf>
--<boundary><crlf>
# Field2
Content-Disposition:form-data; name="<fieldname2>"<crlf><crlf>
<value2><crlf>
--<boundary><crlf>
# File1
Content-Disposition:form-data; name="<fieldname3>" filename="<filename1>"<crlf>
Content-Type: <mimetype><crlf><crlf>       #optional
<binary file data><crlf>
--<boundary><crlf>
# File2
Content-Disposition:form-data; name="<fieldname4>" filename="<filename2>"<crlf>
Content-Type: <mimetype><crlf><crlf>       #optional
<binary file data><crlf>
# Last boundary
--<boundary>--<crlf>

Usage

edit config.js first

module.exports = {
  hostname: 'localhost', //host ip
  port: 9000, // port
  method: 'POST',
  path: '/upload',
  to: '/Users/xiaowen/work/dotload/test/target/'
}

Server

1. install npm i -S dotload
2. vim server.js

const createServer = require('../lib/receiver')
const config = require('./config')
createServer(config)

3. start server

pm2 start server.js --name receiverServer

Client

1. install npm i -S dotload
2. vim upload.js

const upload = require('../lib/upload')
const config = require('./config')
const uploadPath='test/source/'
upload(config,uploadPath)

3. test

node test/upload.js
