我最近从Ruby的Net:HTTP类切换到rest-client 1.6.7.

我发现形成请求要容易得多,但与Net:HTTP请求不同,当rest-client获得200以外的任何东西时,请求就会消失.我已经尝试在RestClient.get之后直接放置一个断点,它永远不会被击中 - 所以我做错了.

def get_member_using_card
  resource = "#{@settings_app_uri}api/v1/card/#{self.member_card_num}?token=#{@settings.api_key}"
  response = RestClient.get resource
  if response.code == 200 
    card = JSON.parse(response.body)
    self.customer_id = card['card']['customer_id']
  else
    return 0
  end
end

这导致了这个堆栈跟踪:

RestClient::ResourceNotFound - 404 Resource Not Found:
        /Users/tim/.rvm/gems/ruby-1.9.2-p290/gems/rest-client-1.6.7/lib/restclient/abstr

有人能告诉我如何正确评估响应代码并防止这种异常发生......？
