+# 明缘进阶场 API（单 FastAPI 服务）
+
+单服务承载 auth / pages / checkin / plan / profile / course-vote / survey / feedback，统一挂载在 `/api/v1` 下。
+
+## 部署
+
+1. 安装依赖：
+
+   ```bash
+   pip install -r server/requirements.txt
+   ```
+
+2. 配置环境变量（复制 `server/.env.example` 后填写）：
+
+   - `WECHAT_APPID` / `WECHAT_SECRET`：微信小程序凭证
+   - `JWT_SECRET`：JWT 签名密钥（>=32 字节随机串）
+   - `ADMIN_KEY`：反馈解决接口的管理密钥
+   - `MYSQL_*`：`mys_info_test` 数据库连接
+   - `SURVEY_DB`：问卷库 `myxhxc`
+   - `PHONE_HMAC_KEY`：手机号 HMAC 密钥，必须与既有 `phone_encrypted` 生成一致（默认 `MingYuan2026AuthKey`）
+   - `H5_BASE_URL`：H5 模块基础地址（默认 `https://muguaclub.cn`）
+   - `FEEDBACK_DIR` / `COURSE_VOTES_FILE` / `PLAN_ATTACH_DIR`：文件存储路径
+
+3. 执行 wechat_openid 迁移（一次性）：
+
+   ```bash
+   mysql mys_info_test < server/migrations/001_add_wechat_openid_column.sql
+   ```
+
+4. 启动：
+
+   ```bash
+   uvicorn server.main:app --host 0.0.0.0 --port 8000
+   ```
+
+5. 健康检查：`GET /api/v1/health` 返回 `{"ok": true}`。
+
+## 认证
+
+- `POST /api/v1/auth/wechat-login`：`{code}`，`wechat_openid` 命中自动登录；未命中返回 `need_phone=true`。
+- `POST /api/v1/auth/bind-phone`：`{code, phone_code}`，手机号匹配后回填 `wechat_openid` 并登录。
+- 受保护接口使用 `Authorization: Bearer <JWT>`，不使用 cookie。
+
+## 小程序
+
+- 目录：`miniprogram/`，四 tab（首页/打卡/计划/我的）。
+- 首页调用 `GET /api/v1/pages/home` 按返回顺序渲染，模块通过 web-view 打开并附带 `?token=`。
+- H5 引入 `h5/shared/auth.js` 后，`fetch` 自动附带 Bearer token。
+
+## 测试
+
+```bash
+python -m pytest tests -q
+```
