推荐答案

HTTParty::Response 有一个 code 属性，它包含 HTTP 响应的状态代码.它以整数形式给出.所以，像这样:

An instance of HTTParty::Response has a code attribute which contains the status code of the HTTP response. It's given as an integer. So, something like this:

response = HTTParty.get('http://twitter.com/statuses/public_timeline.json')

case response.code
  when 200
    puts "All good!"
  when 404
    puts "O noes not found!"
  when 500...600
    puts "ZOMG ERROR #{response.code}"
end
