400 Python中HTTPS连接上的错误请求

Python:3.6.5（蟒蛇） 操作系统：RHEL 6.9

当https通过代理进行连接尝试时，我总是遇到400个错误请求错误。但是，如果没有http和curl，同样可以正常工作。我已经在linux cli中导出了https\u代理和http\u代理。有人建议我怎么做吗

        import requests
        session = requests.Session()
        session.get("https://pypi.python.org/simple/").content

您可以使用

import-urllib.request

和

import-ssl
