AI 解决方案

报错分析报告

1.错误翻译

原文：Failed to fetch
译文：获取资源失败

2. 原因分析

根本原因：网络请求未成功（如连接中断、API端点不可达、超时或跨域限制）。

发生位置：AiSdkToChunkAdapter.convertAndEmitChunk函数中，处理流转换时发起的fetch请求失败。

3.解决方案

// 修复思路：添加网络检查、重试机制与错误捕获
async function safeFetch(url, options = {}, retries = 3) {
  for (let i = 0; i < retries; i++) {
    try {
      const response = await fetch(url, options);
      if (!response.ok) throw new Error(`HTTP ${response.status}`);
      return response;
    } catch (err) {
      if (i === retries - 1) throw err; // 最后一次重试失败则抛出
      await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1))); // 指数退避
    }
  }
}

// 使用示例（替换原fetch调用）
try {
  const stream = await safeFetch(apiUrl, { method: 'POST', body: JSON.stringify(data) });
  // 后续流处理逻辑...
} catch (err) {
  console.error('请求最终失败:', err.message);
}

4. 预防措施

最佳实践1：请求前通过navigator.onLine（浏览器）或ping命令（Node.js）检查网络状态。

最佳实践2：用Axios替代原生fetch，其内置拦截器可统一处理超时、重试与错误日志。

推荐工具：用[Postman](https://www.postman.com/)验证API端点可用性，用[Charles Proxy](https://www.charlesproxy.com/)抓包分析请求链路。

注：若问题持续，需检查API密钥有效性、服务端状态及本地防火墙设置。
