+# 后台独立部署
+
+配置后台是一个独立的 HTTP 服务。桌面端不会自动把后台部署到服务器；必须先在一台长期在线的电脑或服务器上启动后台，再让各桌面端连接它。
+
+使用宝塔面板时，请直接查看 [BAOTA_DEPLOY.md](BAOTA_DEPLOY.md)，里面按宝塔的“文件、Docker、网站、SSL、反向代理”页面逐步说明。
+
+## 需要部署哪些文件
+
+最小部署只需要：
+
+- `admin_backend.py`：后台程序，只有 Python 标准库依赖。
+- `ai_settings.json`：可选，仅用于第一次创建数据库时导入初始模型配置。
+
+以下文件不要从开发电脑复制到新服务器：
+
+- `backend_runtime.json`：本机运行时自动生成，包含临时同步凭证。
+- `backend_connection.json`：桌面端的登录状态，不属于后台。
+- `backend.db`：新部署无需复制；迁移旧后台时才复制，并应妥善保管。
+
+后台首次启动后会创建 `backend.db`。它保存账号、配置和审计记录，是需要定期备份的核心数据文件。
+
+## 方案一：Docker 部署（推荐）
+
+项目已经把 Docker 部署文件单独放在 `backend_deploy` 目录中。在项目根目录执行：
+
+```powershell
+Copy-Item backend_deploy\.env.example backend_deploy\.env
+notepad backend_deploy\.env
+docker compose --env-file backend_deploy/.env -f backend_deploy/compose.yaml up -d --build
+```
+
+编辑 `.env` 时至少设置一个不少于 10 位、同时包含字母和数字的初始管理员密码：
+
+```dotenv
+WECOM_ADMIN_INITIAL_PASSWORD=请替换为强密码
+BACKEND_BIND_IP=127.0.0.1
+BACKEND_PORT=8765
+```
+
+`BACKEND_BIND_IP` 的选择：
+
+- 只允许服务器本机访问：保持 `127.0.0.1`。
+- 需要局域网电脑直连：改为 `0.0.0.0`，并只对可信局域网放行端口。
+- 需要公网访问：保持 `127.0.0.1`，通过 Nginx 或 Caddy 提供 HTTPS，禁止直接暴露 HTTP 端口。
+
+检查运行状态：
+
+```powershell
+docker compose --env-file backend_deploy/.env -f backend_deploy/compose.yaml ps
+Invoke-RestMethod http://127.0.0.1:8765/health
+```
+
+查看日志：
+
+```powershell
+docker compose --env-file backend_deploy/.env -f backend_deploy/compose.yaml logs -f backend
+```
+
+停止服务不会删除数据库：
+
+```powershell
+docker compose --env-file backend_deploy/.env -f backend_deploy/compose.yaml down
+```
+
+不要执行 `down -v`，它会删除保存后台数据库的 Docker 数据卷。
+
+## 方案二：直接运行 Python
+
+服务器安装 Python 3.10 或更高版本后，把 `admin_backend.py` 放到一个单独目录中，然后运行：
+
+```powershell
+python admin_backend.py --host 0.0.0.0 --port 8765
+```
+
+该方式不需要安装 `requirements.txt` 中的桌面端依赖。正式使用时应把命令配置为 Windows 服务、计划任务或 Linux systemd 服务，确保服务器重启后自动启动。
+
+首次启动默认账号为 `admin`。如果没有通过环境变量指定密码，默认初始密码为 `Admin@123456`；首次登录会强制修改。正式部署不要继续使用默认密码。
+
+## 桌面端如何连接
+
+1. 浏览器打开后台地址并完成管理员首次登录和密码修改。
+2. 在后台发布模型与 MCP 配置。
+3. 打开桌面端“AI 人格与能力”页面。
+4. 在“后台同步”区域点击“登录后台”。
+5. 后台地址填写服务器地址，例如 `http://192.168.1.20:8765`；使用反向代理时填写 `https://你的域名`。
+
+登录后桌面端会立即同步，此后会在启动时和运行期间自动同步。
+
+## 数据备份与升级
+
+Docker 部署的数据保存在 `wechat-backend-data` 数据卷中。升级前先备份数据库，再重新构建服务：
+
+```powershell
+docker compose --env-file backend_deploy/.env -f backend_deploy/compose.yaml up -d --build
+```
+
+直接运行 Python 时，停止后台后复制 `backend.db` 即可完成一致性备份。恢复时把数据库放回原目录，再启动后台。
+
+## 常见连接失败
+
+- `WinError 10061`：目标地址没有服务监听。确认后台进程或容器已经启动，并核对 IP 与端口。
+- 服务器本机能打开、其他电脑不能：确认监听地址为 `0.0.0.0`，并检查系统防火墙和云服务器安全组。
+- 浏览器能打开、桌面端不能：登录框中的地址必须包含 `http://` 或 `https://`，不要填写后台管理页的子路径。
+- 公网域名连接失败：检查 HTTPS 证书与反向代理，不要在桌面端使用自签名证书。

+# 宝塔面板部署后台
+
+推荐架构：`桌面端 → HTTPS 域名 → 宝塔 Nginx → 127.0.0.1:8765 → 后台容器`。
+
+后台端口只监听服务器本机，不在云服务器安全组或宝塔防火墙中开放 `8765`。公网只开放 `80` 和 `443`。
+
+## 一、准备域名
+
+准备一个单独的二级域名，例如：
+
+```text
+ai-admin.example.com
+```
+
+在域名服务商处添加 A 记录，指向宝塔服务器的公网 IP。等待解析生效后再申请 SSL 证书。
+
+## 二、上传后台文件
+
+在宝塔“文件”中创建目录：
+
+```text
+/www/wwwroot/wechat-backend
+```
+
+推荐直接上传本项目生成的 `backend_deploy/wechat-backend-baota.zip`，并解压到上述目录。需要重新生成部署包时，在项目目录运行：
+
+```powershell
+powershell -ExecutionPolicy Bypass -File backend_deploy/build_baota_bundle.ps1
+```
+
+解压后应是以下结构，不需要上传桌面端的其他 Python 文件：
+
+```text
+/www/wwwroot/wechat-backend/
+├── admin_backend.py
+├── Dockerfile
+├── compose.yaml
+├── .env.example
+└── README.md
+```
+
+在宝塔“文件”中把 `.env.example` 复制为 `.env`，再修改为：
+
+```dotenv
+WECOM_ADMIN_INITIAL_PASSWORD=替换成至少10位且包含字母和数字的强密码
+BACKEND_PORT=8765
+```
+
+不要上传本机的 `backend_runtime.json`、`backend_connection.json` 或旧的 `.env`。
+
+## 三、使用宝塔“Python 项目”启动
+
+如果已经进入“添加 Python 项目”窗口，按下面填写：
+
+| 字段 | 填写内容 |
+| --- | --- |
+| 项目名称 | `xchat` |
+| Python 环境 | Python `3.10`、`3.11` 或 `3.12`，推荐 `3.12`；不能使用截图中的 `3.6.8` |
+| 启动方式 | `命令行启动` |
+| 项目路径 | `/www/wwwroot/xchat`，以实际上传目录为准 |
+| 启动命令 | `python admin_backend.py --host 127.0.0.1 --port 8765 --db /www/wwwroot/xchat/backend.db --runtime-file /tmp/xchat_backend_runtime.json` |
+| 环境变量 | 选择“指定变量”，添加 `WECOM_ADMIN_INITIAL_PASSWORD=你的强密码` |
+| 启动用户 | `www` |
+| 安装依赖包 | 留空，后台没有第三方依赖 |
+
+如果项目实际解压在 `/www/wwwroot/wechat-backend`，启动命令中的 `/www/wwwroot/xchat` 也要改成 `/www/wwwroot/wechat-backend`。
+
+确认项目目录允许 `www` 用户写入，否则后台无法创建 `backend.db`。在宝塔“文件”中把目录所有者设为 `www` 即可。
+
+提交后打开项目日志。正常日志应包含：
+
+```text
+配置后台已启动：http://127.0.0.1:8765
+```
+
+然后在宝塔终端验证：
+
+```bash
+curl http://127.0.0.1:8765/health
+```
+
+如果返回包含 `"status": "ok"` 的 JSON，说明 Python 项目已经启动成功，可以直接跳到“创建网站和 SSL”。
+
+## 四、使用 Docker 启动（备选）
+
+在宝塔“Docker”中安装 Docker；也可以直接在宝塔“终端”执行下面的命令：
+
+```bash
+cd /www/wwwroot/wechat-backend
+docker compose --env-file .env up -d --build
+```
+
+检查容器状态：
+
+```bash
+docker compose --env-file .env ps
+curl http://127.0.0.1:8765/health
+```
+
+健康检查应返回包含 `"status": "ok"` 的 JSON。若构建失败，在宝塔“Docker → 容器编排”或终端中查看日志：
+
+```bash
+docker compose --env-file .env logs --tail=100 backend
+```
+
+## 五、在宝塔创建网站和 SSL
+
+1. 进入“网站”，添加一个纯静态站点，域名填写准备好的二级域名。
+2. 打开该站点的“SSL”，申请 Let's Encrypt 或 LiteSSL 证书。
+3. 确认证书正常后开启“强制 HTTPS”。
+4. 云服务器安全组和宝塔防火墙只需放行 `80`、`443`，不要放行 `8765`。
+
+建议先申请证书，再配置反向代理，避免 HTTP 文件验证被代理规则影响。
+
+## 六、配置反向代理
+
+打开站点设置中的“反向代理”，新增一条规则：
+
+| 宝塔字段 | 填写内容 |
+| --- | --- |
+| 代理名称 | `wechat-backend` |
+| 目标 URL | `http://127.0.0.1:8765` |
+| 发送域名 | `$host`，没有该选项时保持默认 |
+| 内容替换 | 留空 |
+| 缓存 | 关闭 |
+
+保存后访问：
+
+```text
+https://ai-admin.example.com/health
+```
+
+能够看到健康检查 JSON 后，再访问域名首页登录后台。
+
+## 七、首次登录和桌面端连接
+
+1. 后台网页用户名为 `admin`。
+2. 密码是 Python 项目环境变量或 `.env` 中设置的 `WECOM_ADMIN_INITIAL_PASSWORD`。
+3. 首次登录会要求立即修改密码。
+4. 在后台发布模型配置。
+5. 在“桌面端版本升级”中设置当前正式版本、升级包下载地址和更新说明。
+6. 桌面端固定从云端域名获取配置，无需在本机填写后台地址。
+
+版本号使用 `1.0.0` 这种格式。云端版本与桌面端版本不一致时，软件启动会提示升级：
+
+- 未开启“强制升级”：用户可以立即升级，也可以稍后继续使用。
+- 开启“强制升级”：用户只能前往下载或退出软件，不能进入主界面。
+
+开启强制升级前必须先填写一个可正常打开的 `http://` 或 `https://` 下载地址。当前桌面端版本可在软件窗口标题中查看。
+
+发布新的桌面安装包时，还要把项目 `app_version.py` 中的 `APP_VERSION` 改成新版本号再打包。例如新安装包是 `1.0.1`，云端“最新版本号”和安装包内的版本号都应填写 `1.0.1`。
+
+## 八、更新和备份
+
+更新后台前，在宝塔终端执行：
+
+```bash
+cd /www/wwwroot/wechat-backend
+docker compose --env-file .env stop backend
+mkdir -p /www/backup/wechat-backend
+docker cp wechat-config-backend:/data/backend.db /www/backup/wechat-backend/backend.db
+docker compose --env-file .env start backend
+```
+
+然后覆盖新的 `admin_backend.py` 并重新构建：
+
+```bash
+docker compose --env-file .env up -d --build
+```
+
+不要执行 `docker compose down -v`，它会删除保存数据库的数据卷。
+
+## 九、常见问题
+
+- 日志提示 `hashlib has no attribute pbkdf2_hmac`：旧部署包不兼容宝塔中缺少 OpenSSL PBKDF2 的 Python 环境。上传最新版 `admin_backend.py` 后重启项目。
+- 域名返回 `502 Bad Gateway`：后台容器未启动，或 `127.0.0.1:8765` 健康检查失败。
+- 证书申请失败：确认域名已经解析到服务器；暂时关闭反向代理后重新申请。
+- 桌面端提示无法连接：必须填写完整的 `https://后台域名`，并确保证书受系统信任。
+- 修改 `.env` 密码没有效果：初始密码只在第一次创建数据库时使用，后续密码请在后台网页中修改。
+- 修改版本策略后桌面端没提示：确认桌面端程序已更新到包含版本检查的新版本，并重新完整退出、打开软件。
+- 忘记管理员密码：先停止后台，再使用 Compose 临时任务运行密码重置命令，完成后重新启动：
+
+```bash
+docker compose --env-file .env stop backend
+docker compose --env-file .env run --rm backend python /app/admin_backend.py --db /data/backend.db --reset-admin-password
+docker compose --env-file .env start backend
+```

+通用部署方式见 [BACKEND_DEPLOY.md](BACKEND_DEPLOY.md)。

+# Windows EXE 打包说明
+
+桌面端支持打包成单个 EXE 文件。首次打包需要联网安装构建依赖，后续可复用项目中的 `.build-venv` 和 `.uv-cache`。
+
+## 一键打包
+
+最简单的方法是直接双击项目目录中的：
+
+```text
+一键打包EXE.bat
+```
+
+打包成功后会自动打开 `dist` 文件夹。若打包失败，命令窗口会保持打开并显示原因。
+
+也可以在项目目录打开 PowerShell，运行：
+
+```powershell
+powershell -ExecutionPolicy Bypass -File build_windows_exe.ps1
+```
+
+生成文件位于：
+
+```text
+dist/ZhenAI-WeCom-Assistant-v1.0.0.exe
+```
+
+EXE 可以直接复制到其他 Windows 电脑运行，不需要另外安装 Python。程序运行数据保存在：
+
+```text
+%LOCALAPPDATA%\ZhenYangTangRPA
+```
+
+其中包含云端配置缓存、客服名称本地偏好、聊天记录和登记数据。升级 EXE 不会清空这些资料。
+
+## 目标电脑要求
+
+- 支持 Windows 10 / Windows 11 64 位系统。
+- 不需要安装 Python。
+- 不需要安装 Microsoft WebView2 Runtime；EXE 已内置 Qt WebEngine 浏览器内核、浏览器子进程、中文语言包和资源文件。
+- 需要能够访问云端配置域名和客服网页域名。
+- 第一次打开单文件 EXE 会释放内置浏览器组件，因此启动时间可能比后续稍长。
+
+默认界面使用内置 Qt WebEngine。只有开发调试时主动添加 `--classic-ui` 参数，才会改用依赖系统 Microsoft Edge 的经典界面，正常客户使用无需该参数。
+
+每次执行一键打包时，脚本都会强制检查以下内容：
+
+- 内置 `QtWebEngineProcess.exe` 浏览器子进程
+- Qt WebEngine 核心资源和字符数据
+- `zh-CN` 中文语言包
+- VC++ 运行库
+- 打包后 EXE 能否离线创建浏览器内核并成功加载测试页面
+
+任意一项缺失或浏览器自检失败，打包脚本都会返回失败，BAT 窗口会保留错误信息，不会把该 EXE 当成成功版本交付。
+
+## 发布新版本
+
+1. 修改 `app_version.py` 中的 `APP_VERSION`，例如改为 `1.0.1`。
+2. 重新运行 `build_windows_exe.ps1`。
+3. 把生成的 EXE 上传到可下载地址。
+4. 在云端管理后台“桌面端版本升级”中填写相同版本号和下载地址。
+5. 确认下载地址可用后，再决定是否开启强制升级。
+
+建议发布前在另一台 Windows 电脑上打开 EXE，确认软件能启动、能加载客服页面并能收到云端配置。
+
+## 生成可安装版本
+
+直接双击：
+
+```text
+一键生成安装包.bat
+```
+
+它会先重新生成并验证桌面 EXE，再制作中文 Windows 安装包。第一次制作安装包时，会从 NuGet 软件包源下载固定版本的开源 NSIS 构建工具，并校验文件哈希，后续可直接复用。
+
+安装包生成在：
+
+```text
+dist\installer\甄AI客服-安装包-v1.0.0.exe
+```
+
+安装后的效果：
+
+- 软件名称为“甄AI客服”
+- 自动创建桌面快捷方式
+- 自动创建开始菜单快捷方式
+- 快捷方式名称和安装后的程序名称均为“甄AI客服”
+- 安装到当前用户目录，无需管理员权限
+- 可以在 Windows“已安装的应用”中正常卸载
+- 覆盖安装新版时保留 `%LOCALAPPDATA%\ZhenYangTangRPA` 中的配置和聊天资料
+
+说明：桌面和开始菜单中显示的是“甄AI客服”。安装目录里的主程序会保留打包时的英文文件名，这是 Qt WebEngine 浏览器内核正常启动所必需的，请不要手动重命名安装目录中的 EXE。

+
+```bash

+5. 登录后台，在“桌面端版本升级”中填写最新版本号、下载地址和更新说明。
+6. 开启“强制升级”后，版本不一致的桌面端只能下载新版或退出；未开启时允许稍后继续使用。
+
+首次启用强制升级前，请务必确认下载地址能从客户电脑正常打开。
