python urllib获得[Errno socket error][duplicate]

Question

我正在练习google-python课程。然而，我得到了问题与urllib。下面是简化代码：

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

这段代码实际上是有效的，但是如果我将url更改为其他一些，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)

完整的错误信息如下：

非常感谢你读到这篇文章！

Answer 1

1检查SSL版本

2以确保套接字模块的底部支持SSL编译模式，即当SSL编译器选项打开时。

3端口错误，请检查它

Answer 2

Python目前对ssl的要求比以前严格得多。您可以暂时绕过ssl验证。看看这篇文章。当然，这可能不是一个永久的解决方案，但如果您没有权限配置开发人员。谷歌。com证书，这可能是你能做的最好的了。
