问题原因是：https请求没有忽略ssl认证，
解决办法：在请求头中加verify=False，完美解决
for example：

 >>> requests.get("https://www.baidu.com", verify=False).content
C:\Python27\lib\site-packages\urllib3\connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
