## 解决方案

1. **Implement exponential backoff retry with a maximum number of attempts** (70% 成功率)
   ```
   import time
for i in range(3):
    try:
        response = httpx.get('https://api.example.com/v1/process')
        response.raise_for_status()
        break
    except httpx.HTTPStatusError as e:
        if e.response.status_code == 500:
            time.sleep(2 ** i)
        else:
            raise
   ```
2. **Contact the server administrator to investigate the issue** (90% 成功率)
   ```
   Review server logs for details on the 500 error.
   ```

## 无效尝试

- **Retrying the same request immediately** — Server-side errors often persist; retrying without delay may not help. (80% 失败率)
- **Modifying client-side headers arbitrarily** — The error is server-side; client headers rarely fix it. (90% 失败率)
