python client to support json data

[Koren Lev]

Hi, i am trying to get kub API responses as json data using python client, ex :
from kubernetes import client
v1 = client.CoreV1Api()
nodes_str = str(v1.list_node())
nodes_json = json.loads(nodes_str)

response is not a valid json (many special keys and functions), any idea on how to get that with python client ?

Hi, this client is a standard client based on OpenAPI specification.It transforms returned objects to Python objects. You can find some examples here: https://github.com/kubernetes-incubator/client-python/tree/master/examples
If you want to get a raw JSON response from API Server it will be simpler to call API directly (from urllib, requests or other libraries).

I believe you can add _preload_content=False to your API call and get back the raw JSON response.

_preload_content=False is one way to do it (it will return an object not string, but you can call the appropriate method to get the raw response).

you can also add these to your code:

from kubernetes.client import ApiClient

r=v1.list_node()

rs=ApiClient().sanitize_for_serialization(r)

rsj=json.dumps(rs)
