Fb::Jwt::Auth

Installation

Add this line to your application's Gemfile:

gem 'fb-jwt-auth'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install fb-jwt-auth

Usage

Fb::Jwt::Auth.configure do |config|
  # Service token cache domain
  #
  config.service_token_cache_root_url = ENV['SERVICE_TOKEN_CACHE_ROOT_URL']
end

In order to generate the service access token we need to use Fb::Jwt::Auth::ServiceAccessToken.new.generate or if you require a subject, Fb::Jwt::Auth::ServiceAccessToken.new(subject: subject).generate

In the case you need to configure the service access token as a client

Fb::Jwt::Auth.configure do |config|
  config.issuer = 'fb-editor'
  config.namespace = 'formbuilder-saas-test'
  config.encoded_private_key = 'base64 encoded private key'
end

Using other endpoint versions

Service token cache can have different versions of authenticating a service.

You can configure the version:

Fb::Jwt::Auth.configure do |config|
  config.service_token_cache_api_version = :v3
end

Verifying the token

Fb::Jwt::Auth.new(
  access_token: request.headers['x-access-token-v2'],
  key: 'fb-editor', # service name
  leeway: ENV['MAX_IAT_SKEW_SECONDS'],
  logger: Rails.logger
).verify!
