根因分析

服务器未发送中间CA证书，客户端无法构建信任链。

English

The server did not send the intermediate CA certificate, and the client cannot build the trust chain.

generic

解决方案

  1. 95% 成功率 Configure the server to send the full certificate chain 
    Contact server administrator to include intermediate CA certificates in the server configuration.
  2. 85% 成功率 Provide the missing intermediate CA certificate locally 
    requests.get('https://incomplete.example.com', verify='/path/to/intermediate-ca.crt')

无效尝试

常见但无效的做法:

  1. Disabling SSL verification 70% 失败

    Bypasses security; does not solve the missing intermediate certificate.

  2. Manually downloading the certificate and using it incorrectly 80% 失败

    If the certificate chain is incomplete, the verification still fails.
