# Tutorial by Example, Sinatra Edition
# A simple app that allows a user to first authorize their Dropbox account, and then upload a file to their Dropbox.

  get '/' do
    if params[:oauth_token] then
      dropbox_session = Dropbox::Session.deserialize(session[:dropbox_session])
      dropbox_session.authorize(params)
      session[:dropbox_session] = dropbox_session.serialize # re-serialize the authenticated session
      redirect '/upload'
    else
      dropbox_session = Dropbox::Session.new('key', 'secret')
      session[:dropbox_session] = dropbox_session.serialize
      redirect dropbox_session.authorize_url(:oauth_callback => 'http://localhost:9393')
    end
  end

  get '/upload' do
   redirect '/' unless session[:dropbox_session]
   dropbox_session = Dropbox::Session.deserialize(session[:dropbox_session])
   dropbox_session.mode = :dropbox
   redirect '/' unless dropbox_session.authorized?
   dropbox_session.upload 'testfile.txt', 'Folder'
   uploaded_file = dropbox_session.file 'Folder/testfile.txt'
   'This is the metadata: ' + uploaded_file.metadata.size
  end

  get "/logout" do
    session = {}
    redirect "/"
  end

To use it just insert your key and secret dropbox_session = Dropbox::Session.new('key', 'secret')

And then insert your callback url redirect dropbox_session.authorize_url(:oauth_callback => 'http://localhost:9393')
