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

Question

我已经让omniauth 完美地为我在网络上的rails 应用程序工作。我还为我们的 iPhone 应用程序创建了一个 API 以进行交互，并且我正在尝试让omniauth 工作。

有没有办法将访问令牌（从与 Facebook.app 的集成 iOS 集成中接收）传递给omniauth 以在数据库中创建提供程序条目？

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控制器

  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 用户控制器中，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
