python请求SSL问题

HTTPSConnectionPool(host='cgateway.bjmantis.net.cn', port=443): Max retries exceeded with url: /scrm-course-api/pass/loginNoCode (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1007)')))

解决方案：

pip install pip-system-certs
pip install --upgrade certifi

如果安装不上，开代理或者更换镜像源
