aiohttp / Getting response object out of context manager

I'm currently doing my first "baby-steps" with aiohttp (coming from the requests module).

I tried to simplify the requests a bit so I wont have to use a context manager for each request in my main module.

Therefore I tried this:

async def get(session, url, headers, proxies=None):
  async with session.get(url, headers=headers, proxy=proxies) as response:
       response_object = response
  return response_object

But it resulted in:

<class 'aiohttp.client_exceptions.ClientConnectionError'> - Connection closed

The request is available in the context manager. When I try to access it within the context manager in the mentioned function, all works.
But shouldn't it also be able to be saved in the variable <response_object> and then be returned afterwards so I can access it outside of the context manager?
Is there any workaround to this?

If you don't care for the data being loaded during the get method, perhaps you could try loading it inside it:

async def get(session, url, headers, proxies=None):
      async with session.get(url, headers=headers, proxy=proxies) as response:
          await response.read()
      return response

And the using the body that was read like:

resp = get(session, 'http://python.org', {})
print(await resp.text())

Under the hood, the read method caches the body in a member named _body and when trying to call json, aiohttp first checks whether the body was already read or not.
