RemoteImageFetch

Use Curl::Multi with support for filterable Location: redirects.

The intended use is fetching user specified URIs with libcurl from an application server, while blocking access to local hosts.

Installation

Add this line to your application's Gemfile:

gem 'remote_image_fetch'

And then execute:

$ bundle

Or install it yourself as:

$ gem install remote_image_fetch

Usage

downloader = RemoteImageFetch.new(ip_blacklist: /^(127\.0\.0|10|192\.168)\./)

downloader.download(raw_url) do |result|
  if result.ok?
    # process download
  else
    # handle error?
  end
end

downloader.run

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
