# requests.exceptions.SSLError: HTTPSConnectionPool(host='revoked.example.com', port=443): 超过最大重试次数 (由SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败：证书已被吊销'))引起)

- **ID:** `python/requests-connectionerror-ssl-certificate-verify-failed-crl`
- **领域:** python
- **类别:** network_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

服务器的SSL证书已被颁发CA吊销。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 3.x | active | — | — |

## 解决方案

1. **Contact the server administrator to obtain a new certificate** (95% 成功率)
   ```
   The certificate must be re-issued by the CA.
   ```
2. **Use a different endpoint with a valid certificate** (80% 成功率)
   ```
   requests.get('https://valid-alternative.example.com')
   ```

## 无效尝试

- **Setting verify=False to bypass** — Bypasses security but does not fix the revoked certificate; insecure. (60% 失败率)
- **Using a different SSL library** — The revocation status is checked by the CA, not the library. (90% 失败率)
