解决pyhton aiohttp ssl:None [[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)

解决pyhton aiohttp ssl:证书报错问题,

错误信息>

Cannot connect to host oapi.dingtalk.com:443 ssl:None [[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)]

解决方案就是取消ssl验证;

aiohttp.Connector使用自定义创建ssl_context（有关如何创建ssl上下文对象，请参阅https://docs.python.org/3/library/ssl.html）。
也许您必须使用您的证书链正确配置上下文。

PS aiohttp.Connector(verify_ssl)禁用SSL证书验证。

在 ClientSession()传入ssl 配置
