使用 Rails 和 Devise 进行令牌认证 [英] Token authentication with Rails and Devise

问题描述

我正在关注这篇优秀的文章来设置我的 rails (3.2) API 的身份验证部分:
http://blog.joshsoftware.com/2011/12/23/designing-rails-api-using-rabl-and-devise/

I'm following this excellent article to setup the authentification part of my rails (3.2) API:
http://blog.joshsoftware.com/2011/12/23/designing-rails-api-using-rabl-and-devise/

我已经完成了以下步骤:

I have done the following step:

-将设计添加到 Gemfile

-Added devise to Gemfile

-为用户模型启用设计并运行所需的迁移

-Enabled devise for the user model and ran the migrations required

-我的用户模型是

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable
  devise :token_authenticatable

  attr_accessible :email, :authentication_token, :password, :password_confirmation, :remember_me
end

以及数据库中的 token_authenticable(通过迁移).

as well as the token_authenticable in Database (via a migration).

-将 RegistrationController 子类化为:

-Subclassed the RegistrationController with:

class RegistrationsController < Devise::RegistrationsController
  def new
    super
  end

  def create
    resource = warden.authenticate!(:scope => resource_name, :recall => " {controller_path}#new")
    sign_in(resource_name, resource)
    current_user.reset_authentication_token!
    respond_with resource, :location => after_sign_in_path_for(resource)
  end

  def update
    super
  end
end

-在 routes.rb 中，我有:

-In routes.rb, I have:

devise_for :users, :controllers => {:registrations => "registrations"}

用户创建

我需要以下请求来创建用户并发回 authentification_token:

I'd like the following request to create a user and to send back the authentification_token:

curl -H "Accept: application/json" -H "Content-type: application/json"  -X POST -d '{"user":{"email":"[e-mail]", "password":"pass"}}' 'http://localhost:3000/users.json

我的理解是逻辑应该在注册控制器的创建"方法中(应该创建用户并同时登录他).我想我应该是错的，因为我得到的信息是:

My understanding is that the logic should go in the "create" method of the registration controller (that should create the user and log him in at the same time). I think I should be wrong as the message I got in return is:

{"error":"You need to sign in or sign up before continuing."}

创建和登录新用户的缺失部分是什么?POST 到 users.json 不是映射到 RegistrationController#create 吗?

What is the missing piece to have the new user created and logged ? Isn't POST to users.json mapped to RegistrationController#create ?

用户登录

另外，我想要以下请求来登录用户(一旦检查了登录名/密码，就将他的 authentification_token 发回给他)

Also, I'd like the following request to log a user in (sending him back his authentification_token once the login / password have been checked)

curl -H "Accept: application/json" -H "Content-type: application/json"  -X GET -d '{"user":{"email":"[e-mail]","password":"pass"}}' 'http://localhost:3000/users.json

我想逻辑应该在 RegistrationController 的更新"方法中，但不是 100% 确定.登录完成后，我将添加令牌身份验证以保护其他一些模型的创建/查看.

I guess the logic should go in the "update" method of RegistrationController but not 100% sure about that. Once the login is done I will then add the token authentification to protect the creation / view of some other models.

更新

当我发出:

curl -H "Accept: application/json" -H "Content-type: application/json"  -X POST -d '{"user":{"email":"[e-mail]", "password": "mypass", "phone":"1234567890"}}' 'http://localhost:3000/users.json'

我收到以下消息:

Started POST "/users.json" for 127.0.0.1 at 2012-03-11 20:50:05 +0100
Processing by RegistrationsController#create as JSON
Parameters: {"user"=>{"email"=>"[e-mail]", , "password"=>"[FILTERED]", "phone"=>"1234567890"}, "registration"=>{"user"=>{"email"=>"[e-mail]", "password"=>"[FILTERED]", "phone"=>"1234567890"}, "action"=>"create", "controller"=>"registrations", "format"=>"json"}}
WARNING: Can't verify CSRF token authenticity
Completed 401 Unauthorized in 1ms

为什么没有创建和登录用户以及为什么没有返回 authentication_token 的任何想法?

Any ideas why the user is not created and signed in and why no authentication_token is returned ?

推荐答案

是我的错，我会更新博文.您需要添加以下代码以在您的注册控制器中创建用户

It's my fault, I'll update the blog post. You need to add the following code to create the user in you registration controller

if params[:api_key].blank? or params[:api_key] != API_KEY
  render :json => {'errors'=>{'api_key' => 'Invalid'}}.to_json, :status => 401
  return
end
build_resource
if resource.save
   sign_in(resource)
   resource.reset_authentication_token!
   #rabl template with authentication token
   render :template => '/devise/registrations/signed_up' 
else
   render :template => '/devise/registrations/new' #rabl template with errors 
end

如果您遇到任何问题，请告诉我?
