处理`requests`库时遇到`requests.exceptions.SSLError:HTTPSConnectionPool`错误的解决方案

报错信息

raise SSLError(e, request&＃61;request)
requests.exceptions.SSLError: HTTPSConnectionPool(host&＃61;&＃39;www.baidu.com&＃39;, port&＃61;443): Max retries exceeded with url: / (Caused by SSLError(SSLError(1, u&＃39;[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)&＃39;),))


分析:由于报错SSL证书验证失败,所以这次的访问应该是https协议.但是我们明明使用的是http,所以,猜测访问该网站后,被重定向到了https

解决&＃xff1a;关闭证书验证.因为,如果不关闭,请求总是失败,不能获取到重定向的信息.

安装一下几个requests依赖包&＃xff0c;然后设置, verify&＃61;False

pip install cryptography
pip install pyOpenSSL
pip install certifi


>>> response &＃61; requests.get(&＃39;http://www.baidu.com/&＃39;, headers &＃61; header, verify&＃61;False)
D:\python\lib\site-packages\urllib3\connectionpool.py:858: 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
InsecureRequestWarning)
>>> response.history
[]
>>> response.url
u&＃39;https://www.baidu.com/&＃39;


结果出现警告&＃xff0c;Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings InsecureRequestWarning)

想去掉红框内的内容还需要添加如下代码

# requests.packages.urllib3.disable_warnings()from requests.packages.urllib3.exceptions import InsecureRequestWarning
#关闭安全请求警告
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
