Flexirest: HTTP/parse error handling

HTTP Errors

Sometimes the backend server may respond with a non-2xx/3xx 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, a result accessor (for getting access to the parsed body) and a body accessor (for getting access to the original unparsed body). However, you can make use of the message method (or the to_s method) that will build a nice error message for you (containing the URL and the HTTP method used for the request as well as the HTTP status code and the original body of the response).

begin
  Person.all
rescue Flexirest::HTTPClientException, Flexirest::HTTPServerException => e
  # Display the HTTP status and parsed body
  puts "Backend returned HTTP #{e.status} with following parsed body: #{e.result}"
  
  # Display the unparsed body
  puts "Original body is: #{e.body}"
  
  # Using the message method, same than calling the to_s method
  puts e.message
end

Parse Error

If the original 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.
