使用 python requests 遇到以下错误:

ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)

During handling of the above exception, another exception occurred:
raise MaxRetryError(_pool, url, error or ResponseError(cause))
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host=‘xx.com.cn‘, port=443): Max retries exceeded with url: /passport/login 
(Caused by SSLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)‘))) 

requests.exceptions.SSLError: 

SSL错误, 可以先尝试使用以下方式解决:

1 import  urllib3
2 urllib3.disable_warnings()
session.verify = False
或者
r = requests.post(url, data=body, headers=header, verify=False)

Pycharm requests requests.exceptions.SSLError: HTTPSConnectionPool(host='xx.com.cn', port=443): Max retries exceeded with url: /passport/login (Caused by SSLError(SSLCertVerificationError
