python2.7升级到python3需要对ssl进行校验
所以需要引入模块ssl
import ssl
在urlopen中
context添加ssl._create_unverified_context()
关闭ssl校验即可
url = "https://www.baidu.com"context = ssl._create_unverified_context()get = urllib.request.urlopen(url, context = context ).read() print(get)
但是这种办法不推荐,因为最好不要关闭验证
> from urllib import request >>> url = 'https://www.baidu.com' >>> with request.urlopen(url) as f: ... data = f.read() ... print(f.status)
以上办法可能会无效
取消全局验证
import ssl ssl._create_default_https_context = ssl._create_unverified_context
然后使用urllib.urlopen(‘url’)
