ruby-on-rails - Omniauth 用于 Rails API 中的提供者身份验证

Question

我的 omniauth 在网络上为我的 rails 应用程序完美地工作。我还为我们的 iPhone 应用程序创建了一个 API 来进行交互，我正在尝试让 omniauth 工作。

有没有办法将访问 token (从与 Facebook.app 集成的 iOS 集成接收)传递给 omniauth 以在数据库中创建提供者条目？

现在在我的网络应用程序中，我有一个带有以下代码的身份验证 Controller

  def create
    omniauth = request.env["omniauth.auth"]
    user = User.where("authentications.provider" => omniauth['provider'], "authentications.uid" => omniauth['uid']).first

    if user
      session[:user_id] = user.id
      flash[:notice] = t(:signed_in)
      redirect_to root_path
    elsif current_user
      user = User.find(current_user.id)
      user.apply_omniauth(omniauth)
      user.save
      flash[:notice] = t(:success)
      redirect_to root_path
    else
      session[:omniauth] = omniauth.except('extra')
      flash[:notice] = "user not found, please signup, or login. Authorization will be applied to new account"
      redirect_to register_path
    end
  end

在我的 API 用户 Controller 中，我创建了以下内容:

  def create
    @user = User.new(params[:user])
    @user.save

    # Generate data for omni auth if they're a facebook user
    if params[:fb_access_token]
      graph = Koala::Facebook::API.new(params[:fb_access_token])
      profile = graph.get_object('me')

      @user['fb_id'] = profile['id']
      @user['fb_token'] = params[:fb_access_token]
      @user['gender'] = profile['gender']

      # Generate omnihash
      omnihash = Hash.new
      omnihash['provider'] = 'facebook'
      omnihash['uid'] = profile['id']

      omnihash['info'] = Hash.new
      omnihash['info']['nickname'] = profile['username']
      omnihash['info']['name'] = profile['name']
      omnihash['info']['email'] = profile['email']
      omnihash['info']['first_name'] = profile['first_name']
      omnihash['info']['last_name'] = profile['last_name']
      omnihash['info']['verified'] = profile['verified']

      omnihash['info']['urls'] = Hash.new
      omnihash['info']['urls']['Facebook'] = profile['link']

      omnihash['credentials'] = Hash.new
      omnihash['credentials']['token'] = params[:fb_access_token]

      omnihash['extra'] = Hash.new
      omnihash['extra']['raw_info'] = Hash.new

      puts omnihash

      # Save the new data
      @user.apply_omniauth(omnihash)
      @user.save
    end
