how can I use api for python

[yuzhangqin]

I want to use python to online a workflow
my code:
if test_def["releaseState"] != "ONLINE":
release_url = (
f"{API_BASE}/projects/{PROJECT_CODE}"
"/process-definition/release-process-definition"
)
r2 = requests.put(
release_url,
headers=headers,
params={"processDefinitionCode": code}
)
it's error:
raise RemoteDisconnected("Remote end closed connection without"
http.client.RemoteDisconnected: Remote end closed connection without response
so what is correct
