Server maintenance return correct status code

[jmanprz]

Hi,

Is it possible to return a specific Response object even the server is under maintenance? Currently, when the server is not reachable, it returns:

File "/path/to/file.py", line 141, in extract_from_text response = self.recast.request.analyse_text(text=text) File "/path/to/env/lib/python3.6/site-packages/recastai/apis/request/analyse.py", line 30, in analyse_text raise RecastError(response.json().get('message', '')) File "/path/to/env/lib/python3.6/site-packages/requests/models.py", line 808, in json return complexjson.loads(self.text, **kwargs) File "/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/json/__init__.py", line 354, in loads return _default_decoder.decode(s) File "/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/json/decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/json/decoder.py", line 357, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The idea is to get a response message in order to be able to use the status code from the response and avoid catching the JSONDecodeError.
{ "message": "Requests rendered with success", "results": { "act": "wh-query", "entities": {}, "intents": [], "language": "fr", "processing_language": "fr", "sentiment": "negative", "source": "Pourquoi?", "status": 500, "timestamp": "2017-09-14T17:30:16.467673+00:00", "type": "desc:reason", "uuid": "c443d4fc-f6a6-41d3-8835-54627bd24c49", "version": "2.9.0" } }

Cheers,
JP

Thanks for the issue.
The way we could handle this is to move the line raising the parsing error ( namely: response.json().get('message', '')) into the RecastError's __init__ method to handle the whole error message parsing logic over there.

We'll take a look into this, but in the meantime, feel free to submit a PR :)

Cheers,
