ruby-on-rails - 如何以 json 形式返回 Doorkeeper 访问 token

Question

我正在尝试为 iOS 应用程序创建一个登录系统，其后端由设备和门卫提供支持。

我想限制网络请求的数量，因此不想从凭据中获取 token ，然后将用户详细信息作为单独的请求获取。

这是我当前的尝试:

token = Doorkeeper::AccessToken.create!(application_id: @application_id,
    resource_owner_id: current_user.id, :expires_in => 168.hours)
puts token.token
render :json => {:user => current_user, :token => token.as_json(:include=> token)}, 
    status: :ok, location: :users

但是返回的是:

{"user":{"id":2,"email":"user3@test.com","created_at":"2014-06-12T17:25:12.000Z",
"updated_at":"2014-06-13T12:20:18.536Z",
"firstName":"user","lastName":"test","subscription":null},
"token":{"resource_owner_id":2,"scopes":[],"expires_in_seconds":604800,
"application":{"uid":"[Filtered]"}}}

因此，实际的 access_token key 不会被传回以允许我将来进行调用。我可以看到 token 本身没有在 DoorKeeper::AccessToken.as_json 中返回，但是 token.as_json(:include=> token) 仍然没有返回它.

有谁知道如何以 json 形式返回 AccessToken，包括访问 token 本身？

我处理这个问题的方法是创建一个自定义 token Controller 并覆盖 token 请求操作。在那里我可以将自定义内容附加到响应中。

# app/controllers/custom_tokens_controller.rb
class CustomTokensController < Doorkeeper::TokensController

  # Overriding create action
  # POST /oauth/token
  def create
    response = strategy.authorize
    body = response.body

    if response.status == :ok
      # User the resource_owner_id from token to identify the user
      user = User.find(response.token.resource_owner_id) rescue nil

      unless user.nil?
        ### If you want to render user with template
        ### create an ActionController to render out the user
        # ac = ActionController::Base.new()
        # user_json = ac.render_to_string( template: 'api/users/me', locals: { user: user})
        # body[:user] = Oj.load(user_json)

        ### Or if you want to just append user using 'as_json'
        body[:user] = user.as_json
      end
    end

    self.headers.merge! response.headers
    self.response_body = body.to_json
    self.status        = response.status

  rescue Doorkeeper::Errors::DoorkeeperError => e
    handle_token_exception e
  end
end

只需确保您在routes.rb中指向此 Controller

# routes.rb
Rails.application.routes.draw do

  # Doorkeeper
  use_doorkeeper do
    controllers :tokens => 'custom_tokens'
  end

  # Your other routes here...

end

这已经过测试并且有效，我正在我的项目中使用它。
