Describe the bug

My code:

class request():

    @classmethod
    async def get(self, url, call, *, content=None, headers=None):
        if content is not None:
            if headers is not None:
                async with call.request(method='GET', url=url, json=content, headers=headers) as response:
                    return response
            else:
                async with call.request(method='GET', url=url, json=content) as response:
                    return response
        else:
            if headers is not None:
                async with call.request(method='GET', url=url, headers=headers) as response:
                    return response
            else:
                async with call.request(method='GET', url=url) as response:
                    return response

async def check_premium(guild, owner):
    async with aiohttp.ClientSession() as call:
        jsonstr = {
            "MY": "CONTENT"
        }
        url = "MY URL"
        result = await request.get(url, call, content=jsonstr)
        print(await result.json())

async def test():
    await check_premium('995048257447280770', '553960665581355009')

loop = asyncio.get_event_loop()
loop.run_until_complete(test())

To Reproduce

1. I use client
2. I'm run my classmethod in function

Expected behavior

Maybe you're not familiar with context managers, but you're using async with:

                async with call.request(method='GET', url=url, json=content, headers=headers) as response:
                    return response

Which means when the function returns, the request context is exited and the connection is closed. You won't be able to read anything after that point (and shouldn't really be using the response object at all).

Recommendation is to avoid passing response objects around, it's just likely to cause you more problems. Either return the JSON result directly from that method, or otherwise rework the code.
