# 04-首页（原型）

## 目标

实现 Web 首页原型，展示用户体质信息、快捷入口和健康提示。

---

## 前置要求

- 路由和布局配置完成
- 模拟数据服务已创建
- 登录页面完成

---

## 实施步骤

### 创建体质状态 Store

创建 `src/stores/constitution.ts`：

```typescript
import { defineStore } from 'pinia'
import { ref } from 'vue'
import type { ConstitutionResult } from '@/types'

export const useConstitutionStore = defineStore('constitution', () => {
  const result = ref<ConstitutionResult | null>(null)

  function setResult(data: ConstitutionResult) {
    result.value = data
    localStorage.setItem('constitution_result', JSON.stringify(data))
  }

  function clearResult() {
    result.value = null
    localStorage.removeItem('constitution_result')
  }

  // 初始化时从 localStorage 恢复
  function init() {
    const saved = localStorage.getItem('constitution_result')
    if (saved) {
      result.value = JSON.parse(saved)
    }
  }

  init()

  return { result, setResult, clearResult }
})
```

### 创建首页

创建 `src/views/home/HomeView.vue`：

```vue
<template>
  <div class="home-page">
    <!-- 体质卡片 -->
    <el-card class="constitution-card" :body-style="{ padding: '24px' }">
      <template v-if="constitutionStore.result">
        <div class="constitution-header">
          <span class="label">我的体质</span>
          <el-link type="primary" @click="router.push('/constitution/result')">
            查看详情 →
          </el-link>
        </div>
        <div class="constitution-body">
          <el-icon size="40" color="#10B981"><TrendCharts /></el-icon>
          <div class="constitution-info">
            <h2>{{ constitutionNames[constitutionStore.result.primaryType] }}</h2>
            <p>{{ constitutionDescriptions[constitutionStore.result.primaryType].description }}</p>
          </div>
        </div>
      </template>
      <template v-else>
        <div class="no-constitution" @click="router.push('/constitution')">
          <el-icon size="48" color="#9CA3AF"><Document /></el-icon>
          <p>还未进行体质测试</p>
          <span>点击开始测试，了解您的体质类型</span>

    <!-- 快捷入口 -->
    <div class="quick-actions">
      <el-card
        v-for="action in quickActions"
        :key="action.label"
        class="action-card"
        shadow="hover"
        @click="action.onClick"
      >
        <div class="action-icon" :style="{ backgroundColor: action.bgColor }">
          <el-icon :size="24" :color="action.color">

          </el-icon>
        </div>
        <div class="action-text">
          <h4>{{ action.label }}</h4>
          <p>{{ action.desc }}</p>

    </div>

    <!-- 健康提示 -->
    <el-card class="tip-card">
      <div class="tip-content">
        <el-icon size="24" color="#F59E0B"><Sunrise /></el-icon>
        <div class="tip-text">
          <h4>今日健康提示</h4>
          <p>{{ healthTip }}</p>
        </div>
      </div>
    </el-card>

    <!-- 推荐产品 -->
    <el-card class="products-card">
      <template #header>
        <div class="products-header">
