<H3>3. 使用调试工具查看原始响应</H3>
<p>不要只依赖浏览器下载结果，应通过工具查看实际返回内容。</p>
<font color="#000000">
<ul>
  <li>用 Postman 或 curl 请求接口，保存响应为文件，检查是否可正常打开</li>
  <li>Chrome 开发者工具 → Network → 查看该请求的 Response 内容是否是二进制或报错文本</li>
  <li>临时将文件保存到服务器本地，验证生成是否成功：
    <pre class="brush:php;toolbar:false;">$writer->save('/tmp/test.xlsx'); // 测试生成路径

error\_log("Export data count: " . count($data));

try { ... } catch (Exception $e) { error\_log($e->getMessage()); }
