How save a json file in python from api response when the class is a list and object is not serializable

Question

I have tried to find the answer but I could not find it

I am looking for the way to save in my computer a json file from python.

I call the API

configuration = api.Configuration()
configuration.api_key['X-XXXX-Application-ID'] = 'xxxxxxx'
configuration.api_key['X-XXX-Application-Key'] = 'xxxxxxxx1'

## List our parameters as search operators
opts= {
    'title': 'Deutsche Bank',
    'body': 'fraud',
    'language': ['en'],
    'published_at_start': 'NOW-7DAYS',
    'published_at_end': 'NOW',
    'per_page': 1,
    'sort_by': 'relevance'
}

try:
    ## Make a call to the Stories endpoint for stories that meet the criteria of the search operators
    api_response = api_instance.list_stories(**opts)
    ## Print the returned story
    pp(api_response.stories)
except ApiException as e:
    print('Exception when calling DefaultApi->list_stories: %s\n' % e)

I got the response like this

In the documentation says "Stories you retrieve from the API are returned as JSON objects by default. These JSON story objects contain 22 top-level fields, whereas a full story object will contain 95 unique data points"

The class is a list. When I have tried to save json file I have the error "TypeError: Object of type Story is not JSON serializable".

How I can save a json file in my computer?

Answer 1

The response you got is not json, json uses double quotes, but here its single quotes. Copy paste your response in the following link to see the issues http://json.parser.online.fr/ .

If you change it like [{"author": {"avatar_url": None, "id": 1688440, "name": "Pranav Nair"}, "body": "......

It will work, You can use python json module to do it

import json
json.loads(the_dict_got_from_response).

But it should be the duty of the API provider to, To make it working you can json load the result you got.
