报错分析报告

1.错误翻译

原文：API request failed: 504
译文：API请求失败：504

2.原因分析

3. 解决方案

python
import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry
def safe_api_call(url, max_retries=3, timeout=10):
    session = requests.Session()
    # 配置重试策略（针对504）
    retry = Retry(total=max_retries, backoff_factor=1, status_forcelist=[504])
    adapter = HTTPAdapter(max_retries=retry)
    session.mount("https://", adapter)
    session.mount("http://", adapter)
    
    try:
        resp = session.get(url, timeout=timeout)
        resp.raise_for_status()
        return resp.json()
    except requests.exceptions.RequestException as e:
        print(f"请求失败: {e}")
        return None
使用示例

result = safe_api_call("https://your-api-endpoint.com")
