ruby-on-rails - 使用Devise的API身份验证(Ruby on Rails)

Question

我正在尝试使用devise配置:token_authenticatable在我的项目中通过json添加身份验证。

我有从本文中获取的正在工作的sessions_controller＃create代码-http://blog.codebykat.com/2012/07/23/remote-api-authentication-with-rails-3-using-activeresource-and-devise/

def create
    build_resource
    resource = User.find_for_database_authentication(:email => params[:email])
    return invalid_login_attempt unless resource

    if resource.valid_password?(params[:password])
        resource.ensure_authentication_token!  #make sure the user has a token generated
        render :json => { :authentication_token => resource.authentication_token, :user_id => resource.id }, :status => :created
        return
    end
end

def invalid_login_attempt
    warden.custom_failure!
    render :json => { :errors => ["Invalid email or password."] },  :success => false, :status => :unauthorized
end

问题是 native 设备sessions_controller＃create看起来像这样

  def create
    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_navigational_format?
    sign_in(resource_name, resource)
    respond_with resource, :location => after_sign_in_path_for(resource)
  end

而且我不知道如何结合这两种创建方法以使身份验证在网站上也可以通过json工作？

更新

工作代码

def create
    respond_to do |format|

      format.json do
        build_resource
        resource = User.find_for_database_authentication(:email => params[:email])
        return invalid_login_attempt unless resource

        if resource.valid_password?(params[:password])
          resource.ensure_authentication_token!  #make sure the user has a token generated
          render json: { authentication_token: resource.authentication_token, user_id: resource.id }, status: :created
          return
        end
      end

      format.html do
        self.resource = warden.authenticate!(auth_options)
        set_flash_message(:notice, :signed_in) if is_navigational_format?
        sign_in(resource_name, resource)
        respond_with resource, :location => after_sign_in_path_for(resource)
      end

    end
  end

您希望SessionsController#create方法看起来像这样:

class Users::SessionsController < Devise::SessionsController
  def create
    resource = warden.authenticate!(scope: resource_name, recall: "#{controller_path}#new")
    set_flash_message(:notice, :signed_in) if is_navigational_format?
    sign_in(resource_name, resource)

    respond_to do |format|
      format.html do
        respond_with resource, location: redirect_location(resource_name, resource)
      end
      format.json do
        render json: { response: 'ok', auth_token: current_user.authentication_token }.to_json, status: :ok
      end
    end
  end
end 

...并确保您已将设备配置为使用客户端将传递的 token 身份验证 key 。
