在Python环境中访问HTTPS网站时，包括HTTPS需要使用代理的过程中，如果遇到类似SSL: CERTIFICATE_VERIFY_FAILED相关的错误，说明目标网站的HTTPS证书认证不通过，需要忽略对HTTPS证书的验证，可以在访问之前加上 

import ssl

    try: _create_unverified_https_context = ssl._create_unverified_context

except AttributeError:

# Legacy Python that doesn't verify HTTPS certificates by default 

     pass

else:

# Handle target environment that doesn't support HTTPS verification ssl._create_default_https_context =     _create_unverified_https_context

使Python忽略对证书的验证
