我正在尝试对HTTPS网址进行API调用：

Iam trying to make an API call to a HTTPS url:

response = requests.request("GET", url, headers=headers, params=None, verify=True)

和Iam面临以下错误。当我通过cUrl或Postman调用API时，效果很好。

and Iam facing the following error. It works fine when i invoke the API via cUrl or Postman...

我尝试通过指定 verify = False 来尝试。仍然有错误

I tried by specifying verify=False .Still there is error

关于我如何规避此错误的任何想法？我在这里浏览了各种问题，但找不到解决方案。 URL管理员还确认服务器证书有效，因此我认为这肯定与安装冲突的软件包有关。

Any ideas on how i can circumvent this error ? I Browsed through various questions here but could not find a solution for this. The URL administrator also confirmed that the server certificates are valid so i feel this has definitely got to do something with some conflicting package installation.

这是我的冻结软件包的清单：

Here's my pip freeze list of packages:

推荐答案

最后发现这是网络问题。与我公司的IT团队一起解决了这个问题，他们通过进行一些IP白名单解决了该问题。

Finally figured out that it was a Network issue. Took this up with my company's IT team and they resolved it by doing some IP whitelisting.
