auth-hmac 功能测试问题

Question

我想在我的 api 应用程序中使用这个 gem https://github.com/seangeo/auth-hmac/

我有一个关于为请求身份验证创建测试的问题。 我想用 hmac 签署请求，但是 rails 控制器在下一个代码之后没有 http 标头

 def setup
    #load from fixture
     @client = clients(:client_2)


 end

 def sign_valid_request(request,client)
    auth_hmac = AuthHMAC.new(client.key => client.secret )
    auth_hmac.sign!(request,client.key)
    request
  end

 def test_response_client_xml

      @request =  sign_valid_request(@request,@client)
      get :index  , :api_client_key => @client.key , :format=> "xml"
      @xml_response = @response.body

      assert_response :success
      assert_select   'id' , @client.id.to_s
end

路由有这样的配置

scope '/:token/' do
     # route only json & xml format
    constraints :format=> /(json|xml)/  do
       resources :clients, :only => [:index]
    end

  end

Answer 1

我在功能测试方面遇到了同样的问题。要使用 AuthHMAC 正确签署每个请求，您应该将以下内容放入您的 test_helper.rb

def with_hmac_signed_requests(access_key_id, secret, &block)
  unless ActionController::Base < ActionController::Testing
    ActionController::Base.class_eval { include ActionController::Testing }
  end

  @controller.instance_eval %Q(
    alias real_process_with_new_base_test process_with_new_base_test

    def process_with_new_base_test(request, response)
      signature = AuthHMAC.signature(request, "#{secret}")
      request.env['Authorization'] = "AuthHMAC #{access_key_id}:" + signature
      real_process_with_new_base_test(request, response)
    end
  )

  yield

  @controller.instance_eval %Q(
    undef process_with_new_base_test
    alias process_with_new_base_test real_process_with_new_base_test
  )
end

然后在您的功能测试中：

test "secret_method should be protected by an HMAC signature" do
    with_hmac_signed_requests(key_id, secret) do
      get :protected_method
      assert_response :success
    end
end

Answer 2

你可以试试这个解决方案

  def sign_valid_request(request,client)
    auth_hmac = AuthHMAC.new(client.key => client.secret )
    auth_hmac.sign!(request,client.key)
    # because this would be deleted in request.recycle! method in test framework
    request.env.merge!(request.env['action_dispatch.request.parameters'])
    request
  end

由于 Rails 3 测试单元框架删除了 action_dispatch.request 中的所有值，因此在此处添加了行 request.env.merge!(request.env['action_dispatch.request.parameters'])。

您可以在此处找到此行为：https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/test_case.rb#L404
