帮忙分析一下吧，大神们

icz

requests.exceptions.SSLError: HTTPSConnectionPool(host='movie.douban.com', port=443): Max retries exceeded with url: /top250 (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),))

icz

当你urllib.urlopen一个 https 的时候会验证一次 SSL 证书
当目标使用的是自签名的证书时就会爆出一个
urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)> 的错误消息
解决方案
import ssl  
  
try:  
    _create_unverified_https_context = ssl._create_unverified_context  
except AttributeError:  
    # Legacy Python that doesn't verify HTTPS certificates by default  
    pass  
else:  
    # Handle target environment that doesn't support HTTPS verification  
    ssl._create_default_https_context = _create_unverified_https_context
