RT 今天使用了一下 gem 'zhima_auth' 按照 git 上给的例子测试了一下，报

报错提示太少了，没有思路，就看了下提示的 /usr/local/lib/ruby/gems/2.2.0/gems/zhima_auth-0.3.0/lib/zhima_auth/validation.rb:31:in `check_initialize_response' 的源码， 发现报错信息不一样，感觉比较差异，是我的排错方式不对吗？

def check_initialize_response response
  raise ZhimaAuth::InvalidResponse, "Initialize request failed" unless (response.is_a? Hash) && response["zhima_customer_certification_initialize_response"]
  response_code = response["zhima_customer_certification_initialize_response"]["code"]
  if response_code != "10000"
    response_msg = response["zhima_customer_certification_initialize_response"]["sub_msg"]
    raise ZhimaAuth::InvalidResponse, "#{response_code}#{response_msg}"
  end
  true
end

请教各位大神啦
