🔍 错误分析

1. 🌐 错误翻译

原文：The socket connection was closed unexpectedly. For more information, pass verbose: true in the second argument to fetch()
译文：套接字连接被意外关闭。如需获取更多信息，请在 fetch() 的第二个参数中传递 verbose: true

3. 💡 解决方案

async function fetchWithRetry(url, options = {}) {
  const maxRetries = 3;
  const baseDelay = 1000; // 初始延迟 1 秒

  for (let attempt = 0; attempt < maxRetries; attempt++) {
    try {
      const response = await fetch(url, {
        ...options,
        // 添加超时控制（需配合 AbortController）
        signal: AbortSignal.timeout(10000), // 10秒超时
        // 启用详细日志
        verbose: true,
      });

      if (!response.ok) {
        throw new Error(`HTTP Error: ${response.status}`);
      }

      return response;
    } catch (error) {
      if (attempt === maxRetries - 1) throw error;

      // 仅对连接错误重试
      if (error.name === 'AbortError' || error.message.includes('socket')) {
        const delay = baseDelay * Math.pow(2, attempt); // 指数退避
        await new Promise(resolve => setTimeout(resolve, delay));
      } else {
        throw error;
      }
    }
  }
}

// 使用示例
fetchWithRetry('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('最终请求失败:', error));
