Chunked response incomplete

Chunked response incomplete

$ python -c "import requests; requests.get('http://flaky.example.com/stream', stream=True).iter_content().__next__()"
Traceback (most recent call last):
  ...
urllib3.exceptions.ProtocolError: ('Connection aborted.', ConnectionResetError(...))

Why this happens

Server drops the connection mid-stream or sends malformed termination chunk.

Fix

• Retry the request or support resumable downloads.

Wrong code

import requests
resp = requests.get("http://flaky.example.com/stream", stream=True)
for chunk in resp.iter_content(1024):
    pass  # fails midway

Fixed code

import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

session = requests.Session()
session.mount("http://", HTTPAdapter(max_retries=Retry(total=3, backoff_factor=0.5)))
resp = session.get("http://stable.example.com/stream", stream=True)
for chunk in resp.iter_content(1024):
    # process chunks with retry on failure
    pass
