根因分析

服务器使用自签名证书，默认CA包不信任该证书。

English

The server uses a self-signed certificate that is not trusted by the default CA bundle.

generic

解决方案

  1. 90% 成功率 Provide the self-signed certificate file to verify parameter 
    requests.get('https://internal.example.com', verify='/path/to/cert.pem')
  2. 85% 成功率 Use a custom CA bundle that includes the self-signed certificate 
    requests.get('https://internal.example.com', verify='/path/to/custom-ca-bundle.crt')

无效尝试

常见但无效的做法:

  1. Setting verify=False globally 60% 失败

    Disables security checks, making the connection vulnerable to attacks.

  2. Adding the certificate to the system trust store without proper configuration 70% 失败

    The system trust store may not be used by Python's requests library by default.
