AI 解决方案

##报错分析

1. 错误翻译

原文：Failed to fetch
译文：获取失败

2. 原因分析

根本原因：网络请求未能成功获取数据（Fetch API返回失败）。

发生位置：AiSdkToChunkAdapter.convertAndEmitChunk方法（store-CA-rHPlI.js:322991:64），上下文是该组件转换AI流数据时发起的请求中断。

3.解决方案

优先排查网络连通性与API端点，以下是带重试的修复示例（JavaScript）：

// 带指数退避重试的Fetch封装
async function fetchWithRetry(url, options = {}, retries = 3) {
  try {
    const res = await fetch(url, options);
    if (!res.ok) throw new Error(`HTTP ${res.status}`);
    return res;
  } catch (err) {
    if (retries > 0) {
      await new Promise(r => setTimeout(r, 1000 * (4 - retries))); // 退避延迟
      return fetchWithRetry(url, options, retries - 1);
    }
    throw err;
  }
}

// 替换原请求（示例）
const streamRes = await fetchWithRetry(yourApiUrl, { method: 'POST', body: JSON.stringify(data) });

4. 预防措施

最佳实践1：为网络请求添加指数退避重试机制，应对临时抖动。

最佳实践2：请求前用navigator.onLine（浏览器）或服务端探活检查网络状态。

推荐工具：axios-retry插件（简化重试）、浏览器DevToolsNetwork面板（调试请求）。
