a ruby library to fetch and parse meta tags which represent OpenGraph Protocol and TwitterCard.
Add this line to your application's Gemfile:
gem 'ogpr'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ogpr
require "ogpr"
# Fetch and parse meta tags from the url
ogp = Ogpr.fetch("https://example.com/path/to/page")
# Parse the string as meta tags.
ogp = Ogpr.parse("<meta ....>")
# Fetch OpenGraph meta tag
og = ogp.open_graph
if og
og.each_pair do |k, v|
puts "#{k} => #{v}"
end
end
# Fetch TwitterCard meta tag
card = ogp.twitter_card
if card
card.each_pair do |k,v|
puts "#{k} => #{v}"
end
end
# Fetch all of OpenGraph and TwitterCard meta tag
if ogp.exist?
ogp.title # og:title or twitter:title
ogp.type # og:type or twitter:card
ogp.description # og:description or twitter:description
ogp.image # og:image or twitter:image
ogp.url # og:url or twitter:url
end
After checking out the repo, run bin/setup
to install dependencies. Then, run rake spec

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.
