Some option to call raise_for_status() automatically on any request.

[socketpair]

I have many places where my application issues HTTP-request, for example:

async def get_network_interfaces():
    async with ClientSession() as session:
        async with session.get('http://localhost/network/interfaces') as response:
            response.raise_for_status()  # <- THIS LINE
            return await response.json()

The marked line annoys me, since our programmes forgot to add it too frequently. Unforunatelly, our web services report error with HTTP code 542 and JSON-response of error, so returning from such functions without exception is a bug.

added to master.

PS you should re-use session object

WOW!

1. What did you mean when you say about ClientSession resuse ? As I understand, you suggest to make it global in my application. Where I can read about correct usage pattern ?
2. You have added raise_for_status=False. This is good, but it does not solve my problem. Programmers will forget to set it anyway. Is any way to set it to True globally ?

just use one global ClientSession instance, then you can configure your session once.

global session does connection pooling and cookie sharing if you need cookie

Keep-Alive is more important for me than cookies. So, I already know about such ClientSession usage. Thank you for the advice.
