hz4th_coder e5ff90c46a 新增按需截图功能:滚动截图 + 视觉大模型实时判断
- 新 action=smart:每次截图后用视觉大模型判断主题内容是否已截全、是否还需向下滚动,自动滚动到判定完成,最后纵向拼接成长图
- 默认视觉模型 qwen3.6-plus(autodl),支持 agent-browser / playwright 双后端
- LLM 接口可网页配置:⚙️智能配置弹窗(base_url/api_key/model/提示词/最大滚动次数/滚动比例/超时) + 测试连接 + 持久化到 data/config.json
- 新增 API:GET/POST /api/smart/config、POST /api/smart/test
- 安全兜底:大模型判断失败保守停止、滚动位置不再变化判底部、最大滚动次数上限
- 历史新增 smart 类型:入库拼接长图+AI判断过程日志,详情弹窗可查看每一步截图判断
- 前端:智能模式提示条 + 结果展示拼接长图 + AI判断过程折叠查看 + 历史筛选/徽章/详情

<h3>📚 使用说明</h3>
<p><strong>重要提示:</strong></p>
<ul style="margin: 10px 0; line-height: 1.8;">
<li>🧠 <strong>按需截图</strong>:每次截图后用视觉大模型实时判断是否已截全主题内容、是否还需继续滚动,自动滚动到内容结束并拼接成长图(大模型接口可在「⚙️ 智能配置」修改)</li>
<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>
