AIOHTTPTransport ignore backend mimetype

[mirkan1]

well. this line need to be changed from

result = await resp.json()

to

result = await resp.json(content_type=None)

It was giving me errors while I am trying to get data using headers with API key
EXAMPLE CODE:

query = """query { lookup(placekey: "222-224@5vg-7gr-6kz") { placekey safegraph_core { location_name street_address city region postal_code iso_country_code } } }"""
async def async_main():
    transport = AIOHTTPTransport(
        url='https://api.safegraph.com/v1/graphql',
        headers={'Content-Type': 'application/json', 'apikey': "__KEY__"}
    )
    __query__ = gql(query) 
    async with gql_Client(
        transport=transport, fetch_schema_from_transport=True,
    ) as session:
        result = await session.execute(__query__)
    print(result)
    return result

guys my library depends on gql mainly so, let me know what I can do. I need to make it work async, and this line need to be different I think. I will test it again with the latest patch too. https://pypi.org/project/safegraphQL
version: gql==3.0.0a1

gql/gql/transport/aiohttp.py

Line 228 in af8f223

result = await resp.json()

not working on master branch as well.
__version__ = "3.0.0a6"

Well, it appears that the backend is sending an invalid mimetype, which is causing your problem.
The exception received is:

   raise ContentTypeError(
aiohttp.client_exceptions.ContentTypeError: 0, message='Attempt to decode JSON with unexpected mimetype: text/plain;charset=utf-8', url=URL('https://api.safegraph.com/v1/graphql')

Using result = await resp.json(content_type=None) to ignore the backend mimetype could indeed be done without impact.

It also works directly without modification with the RequestsHTTPTransport

Could you please make a PR with the modification and also a test which fails with the current code?

[mirkan1]

I know true.
But I need to send at least 10 requests at the same asyncio.gather so I need to use aiohttp.py. I can add an argument for that case if you accept it within less than a week, else I will just take your library and implement it as mine with MIT license

[mirkan1]

I will make a PR, ASAP

I wrote same line for requests.py file too line
