The code in this directory contains sample code in Ruby for using SFTP To Go.

Ruby doesn't come bundled with the SFTP libraries from the get-go, so we’ll need to install the required net-sftp gem using bundler.

$ bundle install

In accordance with the 12 factor app cloud development methodology, you should explicitly define your app's dependencies, which would make our Gemfile file look like this:

source 'https://rubygems.org'

gem 'net-sftp', '~> 2.1', '>= 2.1.2'

We'll use the environment variable SFTPTOGO_URL to obtain all the required information for connecting to an SFTP server in a URI format: sftp://user:password@host.

Within our SFTPClient class initializer, the variable is parsed to extract the username, password, host and optional port.

Running the example will do the following:

1. List home directory files (to standard output).
2. Write) a sample file to the remote home directory.
3. Download the sample file to download.txt file so you can see the remote file, locally.
4. Upload the downloaded file to another remote copy.
5. Write a sample CSV data to the remote home directory.
6. Process the remote CSV file in-memory and print its content (without the headers).
