Sinatra LinkedIn¶ ↑

Provides helpers for accessing the LinkedIn API in Sinatra applications. Relies on the LinkedIn gem to do the heavy lifting.

gem install sinatra-linkedin

or if using Bundler, add to your Gemfile:

gem 'sinatra-linkedin'

then run

bundle install

Before using you’ll need to acquire an API key from LinkedIn. Go to the LinkedIn Developer Portal to obtain your key.

Sinatra LinkedIn can be used in either “classic” or “modular” Sinatra apps. For “classic” apps, you only need to require the sinatra-linkedin module and set your API key and API secret.

require 'sinatra'
require 'sinatra/linkedin'

set :linkedin_api_key, 'your api key'
set :linkedin_api_secret, 'your api secret'

get '/public' do
  if authorized?
    "Welcome back!"
  else
    "Oops, you haven't logged in yet. Please <a href='/auth'>login</a>"
  end
end

get '/private' do
  authorize!
  "Thanks for logging in!"
end

It works the same way with a “modular” app; the only difference is that you must register Sinatra LinkedIn explicitly.

require 'sinatra/base'
require 'sinatra/linkedin'

class MyApp < Sinatra::Base
  register Sinatra::Linkedin

  set :linkedin_api_key, 'your api key'
  set :linkedin_api_secret, 'your api secret'

  get '/public' do
    if authorized?
      "Welcome back!"
    else
      "Oops, you haven't logged in yet. Please <a href='/auth'>login</a>"
    end
  end

  get '/private' do
    authorize!
    "Thanks for logging in!"
  end
end

Sinatra LinkedIn provides several routes to help you:

/auth

authorizes the user by setting up a request token and redirecting to the LinkedIn authorization page. Once the user has granted access (or denied it) they will be redirected to /auth/callback (see below).

/auth/callback

stores the token and secret in the session, then redirects to the root URL.

/auth/logout

deletes the token and secret from the session and redirects the user to the root URL.

Sinatra LinkedIn provides these helper methods:

authorized?

returns true if the user has authenticated with their LinkedIn credentials.

authorize!

redirects the user to the /auth route unless they have already been authenticated.

client

provides a handle to the LinkedIn::Client class. Refer to the LinkedIn gem for usage information.

Use GitHub issues for reporting bug and feature requests.

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull).

• Send me a pull request. Bonus points for topic branches.
