import requests
from requests.exceptions import ConnectionError
import time

def call_api(url, max_retries=3):
    for attempt in range(max_retries):
        try:
            response = requests.get(url, timeout=10)  # 设置超时
            response.raise_for_status()
            return response.json()
        except ConnectionError as e:
            print(f"连接失败（第{attempt+1}次），错误：{e}")
            if attempt < max_retries - 1:
                time.sleep(2 ** attempt)  # 指数退避重试
            else:
                raise  # 重试耗尽后抛出异常
        except Exception as e:
            print(f"其他错误：{e}")
            raise

# 使用示例
try:
    result = call_api("https://api.example.com/endpoint")
except ConnectionError:
    print("最终连接失败，请检查网络或API状态")
