-## 首页铃铛接入新订单轮询（2026-07-14）
+## 购物车页面进入不刷新 Bug 修复（2026-07-14）
+
+### 问题
+从商品列表页/分类页加入购物车后，进入购物车页面，新加的商品不显示，只有之前已在购物车里的商品。
+
+### 根因
+1. **购物车页面缺少 `useDidShow`**：`cart.tsx` 仅在 `useEffect([isLoggedIn])` 中调用 `refresh()`，登录状态不变时不会重新拉取数据。从其他页面返回购物车时，页面不刷新。
+2. **商品列表页/分类页直接调 API 加购**：`shop/index.tsx` 和 `shop/category.tsx` 直接调用 `addToCart` API，未通过 `CartContext.addItem`，导致 CartContext 状态不同步（`addItem` 内部会调 `refresh()`）。
+
+### 修改
+1. **`src/pages/shop/cart.tsx`**：导入 `useDidShow`，添加 `useDidShow(() => { if (isLoggedIn) refresh() })`，页面每次显示时从服务端拉取最新购物车数据
+2. **`src/pages/shop/index.tsx`**：导入 `useCartContext`，`handleAddToCart` 改用 `addItem(product, undefined, product.step || 1)` 代替直接调 `addToCart` API；移除 `addToCart` 导入
+3. **`src/pages/shop/category.tsx`**：同上，改用 `useCartContext` 的 `addItem`
 
 ### 需求
 首页顶部搜索栏右侧铃铛图标，门店店员有新订单时能收到提醒。
