Python requests basic命令返回错误怎么了？

Question

我想运行以下3个命令：

import requests
result = requests.get("https://somedomain.xyz/start_page.html")
print(result.status_code)

但我得到一个错误输出：

有人知道什么是问题以及如何解决吗？提前谢谢

Answer 1

您似乎正在访问一个使用自签名证书的站点。默认情况下，这将被视为无效

看看：How to get Python requests to trust a self signed SSL certificate?

Answer 2

import requests
result = requests.get("https://somedomain.xyz/start_page.html", verify=False)
print(result.status_code)

如果您不想保留verify=False，则需要在此处提及相关证书的路径
