使用 Devise (Ruby on Rails) 的 API 身份验证

问题描述：

我正在尝试使用设计配置:token_authenticable 在我的项目中通过 json 添加身份验证.

I'm trying to add Authentication via json in my project using devise configuration :token_authenticatable.

我有从这篇文章中获取的工作 session_controller#create 代码 - http://blog.codebykat.com/2012/07/23/remote-api-authentication-with-rails-3-using-activeresource-and-devise/

I have the working sessions_controller#create code which was taken from this article - 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

问题是本机设计的 session_controller#create 看起来像这样

The problem is that native devise sessions_controller#create looks like this

  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来在网站上和通过 json 进行身份验证?

And i don't know how to combine this two create methods to have authentication working on website and via json too?

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

答

您希望 SessionsController#create 方法看起来像这样:

You want your SessionsController#create method to look something like this:

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

...并确保您已将设计配置为使用您的客户端将传递的令牌身份验证密钥.

...and make sure you've configured devise to use the token authentication key your clients will pass along.
