Twitter OAuth2 Client Library in Ruby.
Add this line to your application's Gemfile:
gem 'twitter_oauth2'And then execute:
$ bundle install
Or install it yourself as:
$ gem install twitter_oauth2
This gem is built on rack/oauth2 gem.
Basically, the usage is same with the underling gem.
The only difference is that this gem is supporting PKCE as default, since Twitter requires it.
require 'twitter_oauth2'
client = TwitterOAuth2::Client.new(
identifier: '<YOUR-CLIENT-ID>',
secret: '<YOUR-CLIENT-SECRET>',
redirect_uri: '<YOUR-CALLBACK-URL>'
)
authorization_uri = client.authorization_uri(
scope: [
:'users.read',
:'tweet.read',
:'offline.access'
]
)
# NOTE:
# When `TwitterOAuth2::Client#authorization_uri` is called,
# PKCE `code_verifier` and `state` are automatically generated.
# You can get it here.
code_verifier = client.code_verifier
state = client.state
puts authorization_uri
`open "#{authorization_uri}"`
print 'code: ' and STDOUT.flush
code = gets.chop
# NOTE: Obtaining Access Token & Refresh Token using Authorization Code
client.authorization_code = code
token_response = client.access_token! code_verifier
# NOTE: Refreshing Access Token using Refresh Token
client.refresh_token = token_response.refresh_token
client.access_token!If you want to get App-only Bearer Token (via grant_type=client_credentials), you need some tweaks as below.
require 'twitter_oauth2'
client = TwitterOAuth2::Client.new(
# NOTE: not OAuth 2.0 Client ID, but OAuth 1.0 Consumer Key (a.k.a API Key)
identifier: '<YOUR-CONSUMER-KEY>',
# NOTE: not OAuth 2.0 Client Secret, but OAuth 1.0 Consumer Secret (a.k.a API Key Secret)
secret: '<YOUR-CONSUMER-SECRET>'
# NOTE: Twitter has Client Credentials Grant specific token endpoint.
token_endpoint: '/oauth2/token',
)
client.access_token!For more usage, read the underling gem's wiki.
