Mapping dynamic response from API

[avjiang]

Hi, great library so far!

I have been using this library for some time, and it really helped me so much throughout this time.
I have a question, can we dynamically read the JSON response?

For example, the success API call will return an array, thus I am using responseArray function. However, if there is something wrong with the request, the API will return an object, with errorCode and errorMessage key. For now, since I don't know how to cater this condition, I can only hardcode the error message.

Is there any function to solve this issue? Thanks!
