import aiohttp
import asyncio

async def main():
    async with aiohttp.ClientSession() as session:
        async with session.get('https://cube.meituan.com/topcube/api/toc/playWayPackage/sendCoupon?k=226281') as resp:
            print(await resp.read())

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

报错信息：

1
aiohttp.client_exceptions.ClientConnectorCertificateError: Cannot connect to host cube.meituan.com:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)')]

解决方法1：

session.get(url, ssl=False)
