[684]requests时报错requests.exceptions.SSLError: HTTPSConnectionPool

报错信息

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

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：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，然后设置, verify=False

pip install cryptography  pip install pyOpenSSL  pip install certifi

>>> response = requests.get('http://www.baidu.com/', headers = header, verify=False)  D:pythonlibsite-packagesurllib3connectionpool.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 [302]>]  >>> response.url  u'https://www.baidu.com/'

结果出现警告，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()
