How can I handle errors with HTTParty?

Question

I'm working on a Rails application using HTTParty to make HTTP requests. How can I handle HTTP errors with HTTParty? Specifically, I need to catch HTTP 502 & 503 and other errors like connection refused and timeout errors.

Answer 1

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
