# 05-体质辨识页面（原型）

## 目标

实现 Web 端中医体质辨识问卷和结果展示，使用本地模拟数据计算结果。

---

## 页面组成

1. **体质首页** - 介绍页面，引导用户开始测试
2. **问卷页面** - 60道题目，逐题作答
3. **结果页面** - 显示体质类型、雷达图、调养建议

---

## 前置要求

- 路由配置完成
- 模拟数据服务已创建

---

## 实施步骤

### 步骤 1：体质首页

创建 `src/views/constitution/ConstitutionView.vue`：

```vue
<template>
  <div class="constitution-page">
    <!-- 已有结果提示 -->
    <el-alert
      v-if="constitutionStore.result"
      type="success"
      :closable="false"
      class="result-alert"
    >
      <template #title>
        <div class="alert-content">
          <span>您已完成体质测评，当前体质：<strong>{{ constitutionNames[constitutionStore.result.primaryType] }}</strong></span>
          <el-button type="primary" link @click="router.push('/constitution/result')">
            查看详细报告 →
          </el-button>
        </div>
      </template>
    </el-alert>

    <!-- 介绍卡片 -->
    <el-card class="intro-card">
      <div class="intro-header">
        <h2>中医体质自测</h2>
        <p>通过科学的问卷调查，分析您的体质类型，为您提供个性化的健康建议。</p>
      </div>
    </el-card>

    <!-- 步骤说明 -->
    <el-card class="steps-card">
      <h3>测试说明</h3>
      <el-steps :active="0" direction="vertical">

        <el-step title="获取分析报告" description="系统将为您分析体质类型并提供建议" />
        <el-step title="个性化建议" description="根据结果提供针对性的健康建议" />
      </el-steps>
    </el-card>

    <!-- 开始按钮 -->
    <el-button
      type="primary"
      size="large"
      class="start-btn"
      @click="router.push('/constitution/test')"
    >
      {{ constitutionStore.result ? '重新测评' : '开始测试' }}
    </el-button>

    <p class="note">建议每3-6个月重新测评一次，以跟踪体质变化</p>

### 步骤 2：问卷页面

创建 `src/views/constitution/ConstitutionTestView.vue`：

```vue
<template>
