3. 💡 解决方案

网络连接问题排查步骤：

# 1. 检查网络连通性
ping 目标服务器地址

# 2. 检查端口是否开放
telnet 目标地址 端口号

# 3. 检查DNS解析
nslookup 域名

# 4. 检查防火墙设置
# Linux
sudo ufw status
# Windows
netsh advfirewall show allprofiles

代码层面添加重试机制和超时设置：

// JavaScript示例 - 添加重试和超时
async function fetchWithRetry(url, retries = 5, timeout = 10000) {
  for (let i = 0; i < retries; i++) {
    try {
      const controller = new AbortController();
      const timeoutId = setTimeout(() => controller.abort(), timeout);
      
      const response = await fetch(url, {
        signal: controller.signal,
        timeout: timeout
      });
      
      clearTimeout(timeoutId);
      
      if (!response.ok) throw new Error(`HTTP ${response.status}`);
      return await response.json();
    } catch (error) {
      console.warn(`尝试 ${i + 1}/${retries} 失败:`, error.message);
      if (i === retries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, 2000 * (i + 1)));
    }
  }
}

# Python示例 - 使用重试装饰器
import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

def create_session_with_retry(max_retries=5, backoff_factor=1):
    session = requests.Session()
    retry_strategy = Retry(
        total=max_retries,
        backoff_factor=backoff_factor,
        status_forcelist=[429, 500, 502, 503, 504],
    )
    adapter = HTTPAdapter(max_retries=retry_strategy)
    session.mount("http://", adapter)
    session.mount("https://", adapter)
    return session

# 使用示例
session = create_session_with_retry()
try:
    response = session.get("https://api.example.com/data", timeout=10)
    response.raise_for_status()
except requests.exceptions.RequestException as e:
    print(f"请求失败: {e}")
