    • 解决方法:将Python升级到2.7.9及以上

      报错信息
    • The server requires SNI (server name indication) and will cause a TLS alert if the SNI extension is not used. SNI is available with python 3 and with python 2.7.9+. For older versions of python see using requests with TLS doesn't give SNI support.
      服务器需要SNI(服务器名称指示),并且如果没有使用SNI扩展会引起TLS警告。python2.7.9以上的版本支持SNI。
