问题

E requests.exceptions.SSLError: HTTPSConnectionPool(host='XXXXX.cn', port=443): Max retries exceeded with url: /app/login(Caused by SSLError(SSLCertVer
ificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1076)')))

venv\lib\site-packages\requests\adapters.py:514: SSLError

 

步骤一

先检查pip有没安装cryptography，pyOpenSSL，certifi（一般安装以下第三方库，即可解决问题）
pip install cryptography
pip install pyOpenSSL
pip install certifi

安装第三方库：pip install --index-url http://mirrors.aliyun.com/pypi/simple/ certifi --trusted-host mirrors.aliyun.com

步骤二

要是以上这些已安装还是继续报错，则在网页请求代码中加上   verify=False（关闭证书验证）   就可以解决报错，代码可运行。

 

产生的额外问题

加入步骤二后，会导致urllib3  在控制台给出警告信息，如下

=================================================================================== warnings summary =================================================================================== testcases/test_roles_privileges.py::test_dogotsn_todayCalc f:\workspace\dogotsn_pytest\venv\lib\site-packages\urllib3\connectionpool.py:988: InsecureRequestWarning: Unverified HTTPS request is being made to host '127.0.0.1'. Adding certificat e verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings

InsecureRequestWarning,

解决方法

在语句前加上以下代码即可不会被报错：
requests.packages.urllib3.disable_warnings()

 

 

 

然后在运行脚本，发现不会再出现警告！
