# 知微 · 微信知识需求分析工具
|
||||
|
||||
一个本地运行的 Python + SQLite 工具。从群聊和私聊里发现反复提问、风险/事故、重复踩坑、后续复用线索，将其整理为带原文证据的知识需求卡，对应 CREATES 的 Choose → Retrieve → Extract / Validate。
|
||||
|
||||
## 交付状态
|
||||
|
||||
- 已实现：可读文件导入、明文 SQLite 表导入、去重和错误行报告、覆盖统计、时间与会话筛选、本地规则分析、脱敏预览、兼容模型 API、后台任务、原文回溯、人工修正、主题合并/拆分、CSV / Markdown 导出。
|
||||
- 已验证：Windows / Python 3.11 的自动化测试；浏览器端样例操作；本机模拟 API 的完整脱敏与证据校验流程。
|
||||
- **尚未完成：Mac 微信 4.1.0.18 加密数据库的直接读取与解密。** 当前执行环境是 Windows，未连接目标 Mac；未声称或验证该版本的解密兼容性。应用不能仅凭选择微信目录就自动获取全部聊天。使用真实数据前，仍需在目标 Mac 取得可读导出。
|
||||
- 已提供 Mac 只读诊断脚本，帮助确认版本、CPU、数据位置、SQLite / 加密文件头与 WAL 状态；不获取密钥，不修改微信数据或系统保护设置。
|
||||
- Intel / Apple Silicon 使用相同 Python 分析代码；本版无需 pip 安装第三方依赖。
|
||||
|
||||
## 在 Mac 上启动
|
||||
|
||||
需要 **Python 3.10 或以上**。将整个项目目录或发布 ZIP 复制到 Mac 并解压，在终端进入目录：
|
||||
|
||||
```bash
|
||||
python3 --version
|
||||
python3 run.py
|
||||
```
|
||||
|
||||
浏览器会打开 <http://127.0.0.1:8765>。关闭终端或按 Ctrl+C 停止服务。也可在目录内运行：
|
||||
|
||||
```bash
|
||||
bash start-mac.command
|
||||
```
|
||||
|
||||
如果希望以后双击启动，可先执行 `chmod +x start-mac.command`。Python 版本过低时，先安装新版 Python。端口被占用则运行 `python3 run.py --port 8766`。不要通过 `file://` 打开 HTML，也不要换成 `localhost`，服务校验 Host，只接受启动时的 `127.0.0.1:端口`。
|
||||
|
||||
Windows 开发环境：`python run.py` 或双击 `start-windows.cmd`。
|
||||
|
||||
## 第一次体验
|
||||
|
||||
1. 在“数据概览”点击“体验虚构样例”：13 条文字/媒体占位记录、两个群聊和一个私聊。示例中的人名、客户与业务都是虚构的，不是用户真实记录。
|
||||
2. 进入“发现知识需求”，时间留空、会话类型选“全部会话”、勾选“跨会话汇总相似问题”，点击“本地发现线索”。无需密钥，不调用网络。
|
||||
3. 会得到 4 张候选主题卡，其中“测试比例怎么确定”包含 3 次讨论、跨群聊与私聊。点击“查看证据与审核”查看原文、修改摘要、记录边界或审核。
|
||||
4. 多张卡片可勾选后合并。单卡包含多个事件时，可在详情勾选部分事件拆出新主题。合并/拆分会重新标为待审核，旧摘要或备注保留在新卡备注。
|
||||
5. 导出 CSV（Excel 可打开）或 Markdown。导出包含本地会话名与分析内容，**不是对外分享的脱敏报告**；分享前请检查。
|
||||
|
||||
## 从 Mac 获取接入诊断
|
||||
|
||||
请在目标 Mac 的项目目录运行：
|
||||
|
||||
```bash
|
||||
python3 scripts/mac_probe.py
|
||||
```
|
||||
|
||||
生成 `mac-wechat-diagnostic.json`（如果已存在，拒绝覆盖）。报告仅包含本机路径、大小、修改时间、文件头判定、应用版本、CPU 与访问错误，不包含消息正文。
|
||||
|
||||
若微信数据在自定义位置，可明确指定目录：
|
||||
|
||||
```bash
|
||||
python3 scripts/mac_probe.py --root "/你的微信数据目录" --output mac-diagnostic-2.json
|
||||
```
|
||||
|
||||
默认检查微信沙盒 Documents、Application Support 和用户 Documents/xwechat_files，最多 8 层、300 个候选数据库，不跟随符号链接，不扫描整块磁盘。路径可能因版本与设置不同而变化；未找到文件不代表没有记录。权限受限会写入 warnings，不会自动提升权限。报告含本地路径，分享前自行检查。
|
||||
|
||||
`sqlite_header` 仅代表有普通 SQLite 文件头；`encrypted_or_unknown` 不是对加密算法的确认。原生数据库中的联系人关联、XML、压缩文本与 BLOB 等仍可能需要版本适配。不要为了运行本工具关闭 SIP 或安装来路不明的提取器。
|
||||
|
||||
当前版本明确不依赖 chatlog 原仓库。2026-10-22 核查时，[原仓库](https://github.com/sjzar/chatlog)仅保留项目移除通知，不能据旧教程假设它仍可安装或支持 4.1.0.18。
|
||||
|
||||
## 导入真实记录
|
||||
|
||||
支持 JSON、JSONL / NDJSON、CSV、TSV、约定格式的 TXT、明文 SQLite（`.db` / `.sqlite` / `.sqlite3`）。浏览器单文件上限 45 MB，单次上限 50 万条。超限需分文件；每次分析最多选择 20 万条。
|
||||
|
||||
标准 JSON 为对象数组，或包含 `messages` / `items` / `data` 数组的对象：
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"id": "消息唯一ID",
|
||||
"conversation": "测试项目群",
|
||||
"conversation_id": "project@chatroom",
|
||||
"kind": "group",
|
||||
"sender": "张三",
|
||||
"sender_id": "user_a",
|
||||
"timestamp": "2026-10-01T09:00:00+08:00",
|
||||
"content": "测试比例怎么确定？",
|
||||
"message_type": "text",
|
||||
"quote": ""
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
CSV 表头使用同名字段，见 `examples/template.csv`。导入界面可填写实际列名映射；时间、发送人、内容必须可解析。单会话文件缺少会话信息时，填写默认会话名称和类型；混合会话记录须在每行提供会话字段。
|
||||
|
||||
- `kind` 为 `group` / `private`。支持“群聊”/“私聊”。缺失时，ID 以 `@chatroom` 结尾识别为群，其余为私聊；请核对分类。
|
||||
- `timestamp` 支持 ISO 8601、常见年月日时间、10 位秒或 13 位毫秒 Unix 时间戳。
|
||||
- 无时区时间按设置中的源时区解释，默认中国时间 `+08:00`，**不使用运行电脑的时区猜测**。统一以 UTC 保存。筛选和界面显示按同一设置的固定 UTC 偏移。跨夏令时数据请使用带时区的源时间；更改设置不会重新解释已导入数据。
|
||||
- 唯一消息 ID 按会话去重。没有消息 ID 时，用会话、发送人、时间、内容、类型、引用去重；真实同秒同内容消息可能合并，结果会提示。不要混合多个账号但复用同样的会话/消息 ID；如需多账号，请使用不同 `--data-dir`。
|
||||
- 发送人缺失、文本内容为空、时间无效、BLOB 等会拒绝对应行，并返回错误行号，其他有效行仍会导入。
|
||||
- 非文字内容保留类型与占位文本，不自动 OCR、转写语音或解析附件。
|
||||
- 不支持未经转换的 HTML、任意 TXT 布局、微信官方备份包、加密数据库。拒绝这些格式，避免把乱码当消息。
|
||||
|
||||
TXT 支持：
|
||||
|
||||
```text
|
||||
[2026-10-01 09:00:00] 张三: 测试比例怎么确定？
|
||||
这一行仍属于张三的消息。
|
||||
[2026-10-01 09:02:00] 李四: 请先确认型号。
|
||||
```
|
||||
|
||||
### SQLite 与 WAL
|
||||
|
||||
上传数据库时只会读取你选中的文件，浏览器不会自动附带 `-wal`。**不要直接复制运行中微信的 `.db` 文件然后视为完整导出。** 对已经明文、字段可读的数据库，可在 Mac 本地用只读 SQLite backup API 导出表（会包含已提交的 WAL 内容）：
|
||||
|
||||
```bash
|
||||
python3 scripts/export_sqlite.py "/路径/可读数据库.db" "消息表名" "/路径/messages.jsonl"
|
||||
```
|
||||
|
||||
脚本不修改源库、不覆盖已有输出。输出保留源列名，可在导入页面配置字段映射。压缩/二进制内容会拒绝导出，避免误导。数据库没有 sender、conversation 等完整字段时，仍需先关联联系人/群成员信息；本版不对未知微信原生 schema 做猜测。
|
||||
|
||||
## 分析与覆盖范围
|
||||
|
||||
时间段可覆盖全部已导入的群聊和私聊；也可指定会话类型、包含/排除会话。包含列表不选代表全部。时间起止均包含边界；填到分钟时边界精确到该分钟的第 0 秒。不填时间即全部时间。结束日期若通过接口只提供日期，则包含当天 23:59:59。
|
||||
|
||||
关键词筛选会剔除不匹配的消息，因此可能破坏上下文。希望分析完整讨论时请留空。
|
||||
|
||||
本地分析先找提问、失败、风险、返工、未来任务等词语，再在同会话内按 30 分钟间隔、最多 30 条消息形成事件候选；用中文二元词片段与英文词相似度合并问题。**规则是可审查的起点，不是准确语义理解**：会漏掉隐含问题、延迟回复和未记录的背景，也可能混入交错话题。模型模式基于相同事件候选进一步提炼，不代表读懂了全部未入选闲聊。原文图片/语音没有转写时，结论可能缺证据。
|
||||
|
||||
“独立事件数”是窗口分段估计，“回答者”只是可能提供经验的人，“重复踩坑”是文本线索，都不能直接作为事故因果、专家能力或个人绩效结论。
|
||||
|
||||
本地优先级为启发式：每个事件 15 分、风险 20 分、返工 15 分、未来复用 10 分，上限 100。模型可调整分类与策略，但分数仍来自本地事件和关键词；仅供排序，不是业务损失评估。人工审核不等于实践验证。
|
||||
|
||||
分析时冻结事件与消息快照，后续导入不会改写历史卡片证据。新增记录须新建分析任务。历史状态、人工编辑和卡片保存在 SQLite，刷新或重启后仍可从分析历史打开。
|
||||
|
||||
## 配置模型 API 与脱敏
|
||||
|
||||
在“模型与脱敏”填写完整兼容接口地址（以 `/chat/completions` 结尾）、模型名和 API Key。本工具不绑定特定供应商；需要支持常规 `messages` 请求并返回 `choices[0].message.content`。模型须能遵守 JSON 与 ID 引用要求；响应不合规时整个任务失败，不保存部分卡片。
|
||||
|
||||
- 远程接口必须 HTTPS；本机 `localhost` / `127.0.0.1` 可用 HTTP。
|
||||
- API Key 仅在 Python 进程内存；重启后重新输入。也可通过 `WECHAT_MODEL_API_KEY` 环境变量提供。不会写入 SQLite、浏览器 localStorage、日志或导出。
|
||||
- 保存接口、预览均不发外部请求。点击“发送这些内容”才把预览的请求体发送给配置的服务；服务商的数据保留政策由你选用的服务决定。
|
||||
- 脱敏覆盖全库已知发送人名/ID、会话名/ID、常见电话号码/邮箱/身份证/IP/网址/凭据与自定义词。代号由本地随机盐生成并保持稳定，映射不发送。时间、消息类型、证据数字 ID 和未替换正文会发送。
|
||||
- **这不是可证明不可逆的匿名化**。自然语言中未知的人名、地址、业务秘密和组合身份线索可能残留；请补充敏感词并检查完整预览。预览最多 30 分钟有效，配置变更后失效，一份预览只能发送一次。
|
||||
- 每批最多约 48000 JSON 字符、30 个事件；超大单事件拒绝发送而非截断。字符数不是精确 token/费用估计，服务商较小上下文窗口可能报错。
|
||||
- 多批串行发送；**不会自动跨批语义合并**，结果中可人工合并。后台页面可等待；关闭浏览器不停止任务，停止 Python 服务会中断。重启后把未完成任务标记失败，不自动重新发送。
|
||||
- 不自动重试、跟随 HTTP 重定向或读取系统代理，避免重复计费与转发脱敏数据。单次 API 等待最长 120 秒。需要代理的环境可使用明确配置的本地兼容网关。
|
||||
- 模型只获得脱敏事件，没有本机文件/命令/网络工具。响应必须引用当前批次存在的事件和消息，事件不能重复或遗漏，证据必须属于该卡的事件；否则拒绝整次结果。
|
||||
|
||||
## 本地数据与备份
|
||||
|
||||
默认数据在项目下 `data/workbench.sqlite3`，包括原文、配置（不含 API Key）、代号盐、分析快照和人工修正。目录在支持 POSIX 权限的系统上设置为 0700。数据库本身未做静态加密，建议放在你的受保护 Mac 用户目录。
|
||||
|
||||
仅绑定 `127.0.0.1`，校验 Host/Origin 和写入令牌，不加载外部 CDN 或遥测。聊天/模型输出以纯文本 DOM 渲染，CSV 中以 `= + - @` 开头的内容会转义以避免公式执行。该工具是单用户桌面工作台，不是多人服务。
|
||||
|
||||
备份：先 Ctrl+C 停止服务，再复制整个 `data` 目录（包含可能存在的 WAL/SHM），或用 SQLite backup API。恢复时停止服务后放回原目录。用 `python3 run.py --data-dir "/其他/数据目录"` 建立独立工作空间；不要在两个进程中同时打开同一数据目录。
|
||||
|
||||
## 开发与验证
|
||||
|
||||
```bash
|
||||
python3 -m unittest discover -s tests -v
|
||||
python3 -m compileall -q wechat_tool scripts run.py
|
||||
```
|
||||
|
||||
测试使用临时数据目录与本机模拟 API，不调用真实模型、不读取用户微信数据。覆盖时区、去重、错误行、跨会话聚类、媒体缺口、脱敏、完整批次、模型虚构证据拒绝、WAL 快照、只读诊断、CSRF、导入 HTTP、历史快照固定、人工合并/拆分/审核和导出。
|
||||
|
||||
源码结构：
|
||||
|
||||
```text
|
||||
run.py 启动入口
|
||||
wechat_tool/store.py SQLite 与筛选
|
||||
wechat_tool/importer.py 文件解析、字段映射、去重
|
||||
wechat_tool/analysis.py 事件、聚类、脱敏与模型结果校验
|
||||
wechat_tool/server.py 本机 HTTP 服务、任务与导出
|
||||
wechat_tool/static/ 无构建依赖的界面
|
||||
scripts/mac_probe.py Mac 环境与数据库头诊断
|
||||
scripts/export_sqlite.py 明文 SQLite / WAL 完整表导出
|
||||
examples/ 虚构样例与导入模板
|
||||
tests/ 无网络依赖的自动化测试
|
||||
```
|
||||
|
||||
后续真实 Mac 验收仍需：确认 4.1.0.18 的可读数据来源，核对所选时间段的消息数/首尾/随机样本，确认群成员身份和引用解析，使用你选择的真实模型 API 验证响应，再扩大到半年的多群数据。这个接入限制是待完成事项，不是已通过的兼容性声明。
