1. 提取主要主题和关键概念
2. 组织成层次分明的结构
3. 使用清晰的标题和子标题
4. 保持内容的逻辑性和完整性
5. 对于长文档，请确保完整处理所有内容，不要截断
6. **重要：如果原文档中包含图片，请按以下方式处理：
   - 识别图片在文档中的位置和上下文
   - 根据图片内容生成准确的描述文字
   - 在相应位置插入图片占位符：![图片描述](图片路径)
   - 图片描述要准确反映图片内容，图片路径可以是相对路径或占位符
   - 确保图片占位符放在逻辑上合适的位置**
7. **重要：如果原文档中包含表格，请完整保留表格结构：
   - 保持表格的Markdown格式
   - 确保所有表格行都被包含
   - 不要省略任何表格内容
   - 对于合并单元格的表格，请使用HTML格式并正确使用rowspan和colspan属性
   - 如果表格结构复杂，优先使用HTML table标签而不是Markdown表格语法**
8. **重要：确保内容完整性：
   - 不要截断任何内容
   - 保持原文的完整性
   - 所有重要信息都要包含在思维导图中**

提取主标题： 识别文章最顶层的主标题（通常为文章题目或书名），并使用Markdown的 # 级别表示。

识别层级标题： 从文章内容中提取所有层级的内容标题（从主标题后的第一个标题开始，Level 1 至 Level 4）。判断层级依据：

视觉与结构特征： 如独立成行/段、位置（行首）、格式（加粗、编号如 1., 1.1, (1), - 等）。

语义逻辑： 标题之间的包含和并列关系。

在Markdown中，使用相应标题级别：

Level 1 标题用 ##

Level 2 标题用 ###

Level 3 标题用 ####

Level 4 标题用 #####

精确保留原文标题文字，不得修改、概括或润色。

处理正文内容： 对于每个标题下的正文内容区块（从该标题后开始，直到下一个同级或更高级别标题前）：

直接保留原文文本，但根据内容结构适当格式化为Markdown。

如果内容是列表（如项目符号或编号列表），使用Markdown列表语法（例如 - 用于无序列表，1. 用于有序列表）。

保持段落和换行不变。

**重要：如果原文档中包含图片，请按以下方式处理：
1. 识别图片在文档中的位置和上下文
2. 根据图片内容生成准确的描述文字
3. 在相应位置插入图片占位符：![图片描述](图片路径)
4. 图片描述要准确反映图片内容，图片路径可以是相对路径或占位符
5. 确保图片占位符放在逻辑上合适的位置**

输出格式： 输出必须是纯Markdown格式的文本，不得包含任何额外说明、JSON或非Markdown元素。确保输出与示例风格一致。直接输出Markdown内容，不要添加任何说明文字。`,de=J||"请将以下内容转换为结构化的Markdown格式：";try{const W=await fetch("http://127.0.0.1:8000/api/ai/generate-stream",{method:"POST",headers:{"Content-Type":"application/json"},body:JSON.stringify({system_prompt:Ie,user_prompt:de,model:"glm-4.5",base_url:"https://open.bigmodel.cn/api/paas/v4/",api_key:"ce39bdd4fcf34ec0aec75072bc9ff988.hAp7HZTVUwy7vImn"})});if(!W.ok)throw new Error(`HTTP error! status: ${W.status}`);const Z=W.body.getReader(),ge=new TextDecoder;let ce="",ve=0;for(;;){const{done:Ee,value:ze}=await Z.read();if(Ee)break;ce+=ge.decode(ze,{stream:!0});const We=ce.split(`
