Sinatra plugin that allows authentication against portier, the successor for Persona. Like Persona, this lets you verify the email identity of a user.

To be a drop-in replacement, the code keeps using the browserid namespace.

To learn more, read about portier.

Note that logins are not done from within a form on your site -- you provide a login form, and that will start up the login flow and redirect back to your main page.

Install the gem sinatra-portier:

gem install sinatra-portier

Then use it in your code:

require 'sinatra'
require 'sinatra/browserid'


register Sinatra::BrowserID

set :sessions, true
# Disabling origin-check is needed to make webkit-browsers like Chrome work. 
# Behind a proxy you will also need to disable :remote_token, regardless for which browser.
set :protection, except: [:http_origin] 
get '/' do
    if authorized?
        "Welcome, #{authorized_email}"
    else
        render_login_button
    end
end

get '/secure' do
    authorize!                 # require a user be logged in

    authorized_email   # browserid email
end

get '/logout' do
    logout!

    redirect '/'
end

See the rdoc for more details on the helper functions. For a functioning example app, start the app in the example directory:

bundle install
bundle exec rackup -p PORT

Available sinatra settings:

• :browserid_url: If you're using an alternate auth provider other than https://broker.portier.io
• :browserid_login_url: URL users get redirected to when the authorize!(redirect: nil) helper is called and a user is not logged in. redirect is an optional parameter to set the redirect target on the function call instead.
• :browserid_button_class: Css class of the login button
• :browserid_button_text: Text of the login button
