我是 Rails 和 webdev 的新手。尝试使用 Rails + Devise + Doorkeeper(如在 https://github.com/doorkeeper-gem/doorkeeper-provider-app 中)为移动应用程序实现简单的 API。

遇到用户已经收到token无法发起授权请求(POST/oauth/token)的问题。 IE。:

curl -F grant_type=password -F username=1@tothetrip.com -F password=12345678 -X POST http://api.to_the_trip.dev/oauth/token

第一次收到:
{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjp7ImlkIjoyLCJlbWFpbCI6IjFAdG90aGV0cmlwLmNvbSJ9fQ.dYai6nH_KYb9YbDltqwFuzCO3i0igR_gw2T7u_TeVcI","token_type":"bearer","expires_in":7200,"created_at":1435864812}

token 转到 oauth_access_tokens 表(JWT 不需要,但不是问题)。

如果我重复此请求,我将收到 422 错误和 rails 页面,其中包含类似内容
    ActiveRecord::RecordInvalid in Doorkeeper::TokensController#create
Validation failed: Token has already been taken

doorkeeper (2.2.1) app/controllers/doorkeeper/tokens_controller.rb:42:in `authorize_response'
doorkeeper (2.2.1) app/controllers/doorkeeper/tokens_controller.rb:4:in `create'

即使我使用 POST/oauth/revoke 撤销 token ,一切都将相同,除了撤销 oauth_access_tokens 中的时间戳。这很奇怪。

我调查了一下,在 doorkeeper gem (access_token_mixin.rb) 中找到了一段代码:
def find_or_create_for(application, resource_owner_id, scopes, expires_in, use_refresh_token)
if Doorkeeper.configuration.reuse_access_token
access_token = matching_token_for(application, resource_owner_id, scopes)
if access_token && !access_token.expired?
return access_token
end
end
create!(
application_id: application.try(:id),
resource_owner_id: resource_owner_id,
scopes: scopes.to_s,
expires_in: expires_in,
use_refresh_token: use_refresh_token
)
end

所以,错误在于创建!方法,它表示我们尝试添加重复项(在堆栈跟踪中)。如果我在Doorkeeper.configure 中设置了reuse_access_token,那就没问题了。但我会在每次授权后收到相同的 token ,据我所知,这是非常不安全的。是的,如果我从 oauth_access_tokens 中手动删除 token ,那么我将能够进行身份验证。

那么怎么了?

我的门卫配置:
Doorkeeper.configure do
# Change the ORM that doorkeeper will use.
# Currently supported options are :active_record, :mongoid2, :mongoid3,
# :mongoid4, :mongo_mapper
orm :active_record

resource_owner_authenticator do
current_user || env['warden'].authenticate!(:scope => :user)
end

resource_owner_from_credentials do |routes|
request.params[:user] = {:email => request.params[:username], :password => request.params[:password]}
request.env["devise.allow_params_authentication"] = true
user = request.env['warden'].authenticate!(:scope => :user)
env['warden'].logout
user
end

access_token_generator "Doorkeeper::JWT"
end

Doorkeeper.configuration.token_grant_types << "password"

Doorkeeper::JWT.configure do
#JWT config
end

路线:
require 'api_constraints'

Rails.application.routes.draw do
use_doorkeeper
devise_for :users
namespace :api, defaults: {format: :json}, constraints: { subdomain: 'api' }, path: '/' do
scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
resources :users, :only => [:show, :create, :update]

get '/me' => "credentials#me"
end
end
end

最佳答案

好吧,如果你想找到答案,那么就提出一个问题。

问题在于 Doorkeeper::JWT token 的默认实现。它在有效载荷中没有任何随机性,因此对于每个用户的身份验证总是相同的。所以我补充说:

Doorkeeper::JWT.configure do
token_payload do |opts|
user = User.find(opts[:resource_owner_id])
{
iss: "myapp", #this
iat: DateTime.current.utc.to_i, #this
rnd: SecureRandom.hex, #and this

user: {
id: user.id,
email: user.email
}
}
end

secret_key "key"

encryption_method :hs256
end

它工作正常。
