python urllib 得到 [Errno 套接字错误]

Question

我正在练习 google-python 课程。但是，我遇到了 urllib 的问题。这是简化的代码：

import urllib
url = 'http://www.google.com'
ufile=urllib.urlopen(url)

这段代码确实有效，但如果我将 url 更改为其他代码，例如：

url = 'https://developers.google.com/edu/python/utilities#exceptions'

它会引发错误：

IOError: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED]   certificate verify failed (_ssl.c:590)

完整错误信息如下：

非常感谢您阅读本文！

Answer 1

1 检查 SSL 版本

2 确保socket模块底层是支持SSL编译模式的，即开启SSL编译选项时

3端口错误，检查

Answer 2

Python 对 ssl . You can temporarily bypass the ssl verification. Take a look at this post 严格得多。当然，这可能不是一个永久的解决方案，但如果您无权配置 developers.google.com 证书，那可能是您能做的最好的。
