我最近从 Ruby 的 Net:HTTP 类切换到了 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 得到 200 以外的任何内容时,请求就会终止。我尝试在 RestClient.get 之后直接放置一个断点,但它永远不会被击中 - 所以我做错了什么。
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:

有人可以告诉我如何正确评估响应代码并防止此异常发生...?
