有什么想法可以解决这个问题吗？显然SSL验证工作不正常，但我不知道如何解决问题。
在Mac Os上使用Python 3.6.1
谢谢
不久前我遇到过这个问题。尝试给出以下命令：
如果这不起作用，请尝试以下操作：
尝试请求模块。我正在使用Windows，所以尝试相当于一个pip安装的mac。使用Python 3.6，我相信urllib一直存在一些问题。如果您正在尝试使用webscrape，则请求模块比urllib模块更适合Python 3。
下面是我在维基百科上搜索股票代码的另一天的例子：
response = requests.get("https://en.wikipedia.org/wiki/List_of_S26P_500_companies")
soup = bs4.BeautifulSoup(response.text)
我通过使用请求模块得到了网址，然后能够使用美丽的汤来处理文本。从我收集的内容来看，对于Python 3+来说，urllib应该始终被避免，并且更适合Python 3.尽量完成您正在做的事情，但是通过请求模块而不是urllib。
