stream disconnected before completion: stream closed before response.completed

原文：stream disconnected before completion: stream closed before response.completed
译文：流在完成前断开连接：流在响应完成前被关闭

🎯 原因分析

• 网络不稳定或中断导致 TCP 连接提前关闭


• 服务器中途异常终止响应流


• 客户端取消了请求或主动关闭了连接


• 代理或网关超时截断了长连接

💡 解决方案

// 修复后的代码示例（Node.js 流处理）
async function fetchWithRetry(url, retries = 3) {
  for (let i = 0; i < retries; i++) {
    const response = await fetch(url);
    const reader = response.body.getReader();
    try {
      while (true) {
        const { done, value } = await reader.read();
        if (done) break;
        // 处理数据块
      }
    } catch (err) {
      if (i < retries - 1) {
        console.log(`重试第 ${i + 1} 次`);
        continue;
      }
      throw err;
    }
  }
}

// 或使用带超时控制的流读取
const controller = new AbortController();
const timeout = setTimeout(() => controller.abort(), 30000);

try {
  const response = await fetch(url, { signal: controller.signal });
  // 处理流式响应
} finally {
  clearTimeout(timeout);
}
