Question

我将首先道歉-我在论坛上搜索了数周，但没有找到解决方案。我拼凑了很多其他人发现的东西，但是我不太了解下一步需要做什么。

Windows10，Python3.7

我正在尝试浏览公司网站并自动执行一些与工单相关的任务。尝试访问该站点时，我收到所有与未通过Python验证的证书有关的错误。在reddit / SO / ect等其他网站上则不会发生这种情况。该网站也只能在公司内部网上访问。

我可以使用request.get（url，verify = False）来解决这个问题，但是我不想让自己面对安全问题。

>>> from OpenSSL import SSL
>>> import requests
>>> import certifi
>>> url = "https://me-help.xyzcompany.com/helpdesk/WebObjects/Helpdesk.woa"
>>> page = requests.get(url)

>>> print(certifi.where())
C:\Users\MyName\AppData\Local\Programs\Python\Python37-32\lib\site-packages\certifi\cacert.pem
>>> print(ssl.get_default_verify_paths().capath)
None

我尝试使用C：\ Program Files（x86）\ Common Files \ SSL / cert.pem将REQUESTS_CA_BUNDLE添加为环境变量，但这也不起作用。

有人有什么建议吗？我一直在阅读和阅读，找不到可靠的解决方案。我看到其他一些具有相同问题的用户也可以联系其IT部门将其列入白名单，但我认为这不是我的选择。
