I am using the Python package aiohttp
and want to access the async with
expression (the with-item response
) within an except
block:
try:
async with session.get(url, params={'user_id': user_id}) as response:
return await response.json()
except (ClientConnectionError, asyncio.TimeoutError) as e:
logger.error(f'{response.url} raised {e}')
raise
As I understand, the context of response
is closed when a ClientConnectionError
or asyncio.TimeoutError
is raised since it is outside of the async width
block. As a consequence, calling response.url
raises an UnboundLocalError
.
How can I manually use __aenter__
and __aexit__
(see PEP 492) to rewrite the above snippet and keep the response context in the except
block?
