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

import asyncio 
import sys
import pymysql.cursors
from aiohttp import ClientSession
from aiohttp import TCPConnector

async def postmsg(url,msg):     
    async with ClientSession(connector=TCPConnector(verify_ssl=False)) as session:                
        # data={"msgtype":"text","text":{"content":msg},"at":{"atMobiles":["17633919216"],"isAtAll":"false"}}               
        async with session.post(url,data=json.dumps(msg),headers=headers) as response:           
            response = await response.read()                         
            # print(response) 
            return  response
