+# 肉垫计划小程序
+
+用微信开发者工具导入 `pets-fe`，AppID 见 `project.config.json`。接口基础地址在 `utils/config.js`，正式环境为 `https://pet.sundynix.cn/api`。请求封装会追加 `/pets`、`/walks` 等路径，不会再追加一层 `/api`。
+
+## 核心流程
+
+- 宠物：添加、编辑、上传头像、归档；档案使用文件 ID，服务端返回可显示的头像地址。
+- 日常任务：按日期查看完成情况，新增、编辑、删除任务，记录或取消当天完成状态。
+- 遛狗：可一次选择多只宠物，记录轨迹、暂停、继续、结束；历史页可查看路线和同行宠物。
+- 位置分享：开始遛狗后主动开启，分享给微信好友；结束遛狗自动关闭。定位更新发生在小程序打开期间，后台持续定位还需微信对应类目与接口权限。
+- 约遛：发起活动、选择地点和同行宠物、报名、查看报名状态、退出或取消活动。
+
+## 真机检查
+
+1. 登录后添加至少两只宠物，确认头像上传与档案编辑。
+2. 新建喝水、喂食任务，编辑时间并切换日期，验证完成状态。
+3. 同时选两只宠物开始遛狗，确认定位、暂停/继续、分享和结束；在历史页查看记录。
+4. 用另一个微信账号报名约遛，确认已报名和退出状态。
+
+小程序源码约 600 KB，低于微信主包 2 MB 限制。真机调试前请确认小程序后台已配置 `pet.sundynix.cn` 为合法请求域名。
