+# CoffeeChat
+
+面向会展现场社交的微信小程序。用户通过微信登录后，可浏览和筛选活动、查看会展信息、加入活动、填写参与目的，并在管理员审核后查看活动微信群。
+
+## 目录
+
+- `miniprogram/`：原生微信小程序
+- `server/`：Node.js API、管理后台和数据库迁移
+- `deploy/`：Docker Compose 生产部署
+- `.gitea/workflows/`：Gitea Actions 测试及部署
+- `docs/`：接口、配置和上线说明
+
+## 本地启动
+
+1. 复制 `.env.example` 为 `.env`，填写微信 AppSecret 和安全密钥。
+2. 执行 `docker compose -f deploy/docker-compose.yml up --build`。
+3. 将 `miniprogram/config.js` 中的 `apiBaseUrl` 改为已加入微信后台 request 合法域名的 HTTPS 地址。
+4. 使用微信开发者工具打开仓库根目录。
+
+管理后台位于 `https://你的域名/admin/`，登录凭据为环境变量 `ADMIN_TOKEN`。
+
+完整部署及微信平台配置见 [docs/deployment.md](docs/deployment.md)。

+# 生产部署
+
+## 1. 主机准备
+
+`minecraft-and-affine-server` Gitea Runner 需要可执行 Docker Compose，并且 Runner 服务账号必须能读取 `/opt/coffeechat/.env`。建议将该文件权限限制为该账号可读：
+
+```dotenv
+POSTGRES_PASSWORD=随机数据库密码
+JWT_SECRET=至少32位随机字符串
+WECHAT_APP_ID=小程序AppID
+WECHAT_APP_SECRET=小程序AppSecret
+ADMIN_TOKEN=随机管理令牌
+PUBLIC_BASE_URL=https://你的正式域名
+COFFEECHAT_PORT=3100
+```
+
+推送 `main` 后，Runner 会构建容器、执行幂等迁移并启动服务。PostgreSQL 和上传图片分别保存在 `coffeechat-db`、`coffeechat-uploads` Docker 卷中，重新发布不会丢失。
+
+## 2. HTTPS 反向代理
+
+将正式域名反向代理至 `127.0.0.1:3100`，必须启用有效 HTTPS。健康检查路径为 `/health`，管理后台为 `/admin/`。
+
+## 3. 微信公众平台
+
+1. 在“开发管理 → 开发设置”获取 AppSecret，填入服务器环境文件，不得提交仓库。
+2. 将正式 HTTPS 域名加入 `request` 和 `uploadFile` 合法域名。
+3. 修改 `miniprogram/config.js` 的 `apiBaseUrl`。
+4. 使用微信开发者工具完成真机测试、代码上传和体验版审核。
+
+微信群通过二维码加入。二维码由用户提交，管理员在 Web 后台审核；审核通过前不会对其他参与者展示。微信群二维码可能过期，管理员应在审核时验证有效性。
+
+## 4. 数据备份
+
+建议每天备份 `coffeechat-db` 卷中的 PostgreSQL，并同步备份 `coffeechat-uploads` 卷。恢复时必须同时恢复数据库与上传目录，避免图片记录与文件不一致。
