<p><strong>重要提示：</strong></p>
|
||
<ul style="margin: 10px 0; line-height: 1.8;">
|
||
<li>📝 <strong>提取文本</strong>：自动剔除脚本/样式/标签，得到干净的前端可读文本，适合直接用于分析/喂给大模型</li>
|
||
<li>⏱️ <strong>页面加载等待</strong>：某些网站需要验证过程（如 Cloudflare），请设置较长时间（10000-30000ms）</li>
|
||
<li>🔄 <strong>滚动次数</strong>：用于加载动态内容（如微博、推特等），建议 3-5 次</li>
|
||
<li>🎯 <strong>全页截图</strong>：滚动加载后建议开启此选项</li>
|
||
<li>📜 <strong>提取历史</strong>：每次提取自动入库，支持分页浏览、按类型筛选、搜索与删除</li>
