windows - python : bad handshake error on get request when executed on windows but not linux

Question

我写了一个 python 脚本来下载网站的内容，当我在 linux 机器上执行它时它工作得很好，但在 windows 上却不行(它需要在 windows 上执行)。

这是生成错误的代码:

   import requests
   c = requests.Session()
   url = 'https://ted.jeancoutu.com/action/login'
   c.get(url)

这是我在 Windows 机器上执行代码时收到的错误消息:

Traceback (most recent call last):

    raise SSLError(e, request=request)
requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'SSL23_GET_SERVER_HELLO', 'sslv3 alert handshake failure')],)",)

我找不到这个问题的解决方案。我尝试了很多在网上找到的建议，但没有任何效果。我安装了 pyOpenSSL、ndg-httpsclient 和 pyasn1，但没有结果。我也升级了 ssl，但仍然没有。

谢谢你的建议

网站 ted.jeancoutu.com 仅支持 RC4-SHA 和 RC4-MD5 密码(参见 SSLLabs report。RC4 密码被认为是不安全的，因此已从 version 2.5.2 in 02/2015 的请求中的默认密码集中删除。您可能在 Linux 上使用旧版本的请求，因此它仍然有效，但在 Windows 上使用较新版本时失败。

参见 https://stackoverflow.com/a/32651967/3081018了解如何通过启用不安全密码来解决问题。
