Flexirest: HTTP/parse error handling

Sometimes the backend server may respond with a non-200/304 header, in which case the code will raise an Flexirest::HTTPClientException for 4xx errors or an Flexirest::HTTPServerException for 5xx errors. These both have a status accessor and a result accessor (for getting access to the parsed body):

begin
  Person.all
rescue Flexirest::HTTPClientException, Flexirest::HTTPServerException => e
  Rails.logger.error("API returned #{e.status} : #{e.result.message}")
end

If the response is unparsable (e.g. not in the desired content type), then it will raise an Flexirest::ResponseParseException which has a status accessor for the HTTP status code and a body accessor for the unparsed response body.
