Question

使用HTTParty测试帖子时遇到以下错误：

NoMethodError (undefined method `gsub' for nil:NilClass):
  app/models/user.rb:44:in `authorized_domain_referer?'
  app/controllers/api/v1/events_controller.rb:17:in `create'

当我在rails控制台中运行以下内容时：

HTTParty.post("http://localhost:3000/api/v1/events.json", body: {auth_token: User.last.authentication_token}, headers: {"HTTP_REFERER" => "http://one.com"}).parsed_response

这很奇怪，因为当我刚运行User.last.authentication_token时，我得到与用户关联的令牌：

User.last.authentication_token
 => "eb7bba8f1fc297a4f16a198b153015217c4ade87610e7aec78a36f0f0c33"

这是错误之前的完整输出：

我的authorized_domain_referer？ class是以下，它存储在我的用户模型中：

before_create :set_authentication_token

  def authorized_domain_referer?(request_origin)
    encoded_url = URI.encode(request_origin)
    uri = URI.parse(encoded_url)
    domain_name = "#{uri.scheme}://#{uri.host}"
    self.domains.where(url: domain_name).any?
  end

我的base_controller如下：

class Api::BaseController < ApplicationController

  respond_to :json, :xml

  skip_before_filter :verify_authenticity_token

  before_filter :authenticate_from_user_token!
  before_filter :authenticate_user!

  before_filter :cors_preflight_check
  after_filter :set_headers

  def authenticate_from_user_token!
    token = params[:auth_token]
    user = User.where(authentication_token: token).first
    if user
      sign_in user, store: false
    end
  end

即使用户经过适当的身份验证并登录，任何人都知道为什么它会成为Nilclass？

...谢谢
