Python 请求 "certificate verify failed"

Question

我正在维护一个使用请求 + HTTPS 的 Python 迷你应用程序。

在 HTTPS URL 中主机名的 IP 地址更改(合法)之前，该应用程序一直有效。如果我将浏览器指向该 URL，我可以很好地检索它。

Python/requests 在哪里保存 ssh 的 known_hosts 的模拟，我如何为这个主机清除它？

$ python --version
Python 2.7.3

$ cat foo.py 
import requests
url = "https://somehost/resource.json"
requests.get(url, timeout=5, config={'danger_mode': True})

$ source venv/bin/activate
$ python foo.py 
Traceback (most recent call last):

您使用的是旧版本的请求。如果您升级到 2.0 并且您的站点存在证书不匹配，您将获得更有用的消息，您可以通过指定能够验证中间证书的系统证书来修复它。您也可以只请求不按照 Andre 的建议验证您的证书。
