HTTPS Request SSL Certificate validation

Import Urllib2url = "https://www.12306.cn/mormhweb/" headers = {"User-agent": "mozilla/5.0 (Windows NT 10.0; Win64; x64) applewebkit/537.36 (khtml, like Gecko) chrome/54.0.2840.99 safari/537.36 "}request = urllib2. Request (URL, headers = headers) Response = Urllib2.urlopen (request) print response.read ()

　　

Operation Result:

urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>

Therefore, if you encounter such a site in the future, we need to handle the SSL certificate separately, let the program ignore the SSL certificate validation error, can be accessed normally.
