MessageCard 组件统一实现计划

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 提取 MessageCard.vue 组件，统一 story-card 和 result-chat-list 中 AI 消息卡片的样式，并按 100 字阈值自动切换短消息/完整卡片模式

Architecture: 新建 MessageCard.vue 组件封装长消息卡片结构，ScriptView.vue 中 story-card 和 result-chat-list 都复用该组件，短消息直接渲染简洁气泡

Tech Stack: Vue 3, UniApp, 微信小程序

文件结构

创建：

mini-program/src/components/MessageCard.vue - 通用 AI 消息卡片组件

修改：

mini-program/src/pages/main/ScriptView.vue - 替换 story-card 和 result-chat-list 中的 assistant 消息渲染，并迁移相关样式

Task 1: 创建 MessageCard.vue 组件（短消息模式 + 基础结构）

Files:

Create: mini-program/src/components/MessageCard.vue
Modify: 无
Step 1: 创建组件文件并写入基础模板

在 mini-program/src/components/MessageCard.vue 写入以下内容：

<template>
  <view v-if="isShortMessage" class="chat-bubble system">
    <text>{{ content }}</text>
  </view>
  <view v-else class="story-card" :class="{ collapsed }">
    <view class="story-head">
      <view class="story-title-wrap">
        <text class="story-title">{{ title || '我的人生剧本' }}</text>
        <view v-if="tags?.length" class="tag-row">
          <text v-for="tag in tags" :key="tag" class="tag">{{ tag }}</text>
        </view>
      </view>
      <view class="story-head-actions">
        <button class="collapse-icon" @click="$emit('toggle-collapse')">
          <text class="collapse-icon-text">{{ collapsed ? '展开' : '收起' }}</text>

Step 2: 验证组件文件创建成功

确认文件路径：mini-program/src/components/MessageCard.vue 存在。

ls "G:/IdeaProjects/emotion-museun/mini-program/src/components/MessageCard.vue"

Step 3: 提交组件创建

cd "G:/IdeaProjects/emotion-museun"
git add mini-program/src/components/MessageCard.vue
git commit -m "feat: 创建 MessageCard 组件

封装长消息/故事卡片结构，支持短消息简洁气泡模式"

Task 2: 在 ScriptView.vue 中注册并使用 MessageCard 组件

Files:

Modify: mini-program/src/pages/main/ScriptView.vue
Step 1: 导入组件

在 ScriptView.vue 的 <script setup> 顶部，导入 MessageCard 组件：

修改前：

import { computed, nextTick, onMounted, onUnmounted, ref, watch } from 'vue'

修改后：

import { computed, nextTick, onMounted, onUnmounted, ref, watch } from 'vue'
import MessageCard from '../../components/MessageCard.vue'

Step 2: 替换 story-card 模板

找到第 172-219 行的 story-card 模板，替换为 MessageCard 组件。

修改前：

<view class="story-card" :class="{ collapsed: storyCollapsed, dialogMode: resultHasScriptReplies }">
  ...（原有 story-card 全部内容）...
</view>

修改后：

<MessageCard
  :content="displayedResultContent"
  :title="currentResult?.title"
  :tags="resultTags"
  :collapsed="storyCollapsed"
  :content-length="displayedResultContent.length"
  :is-short-message="false"
  :tts-icon="ttsActionIcon"
  :tts-text="ttsActionText"
  @toggle-collapse="toggleStoryCollapse"
  @copy="copyResultContent"
  @change-direction="changeDirection"
  @not-like-me="notLikeMe"
  @continue="continueInChat"
  @play-tts="trackTtsClick"
/>

Step 3: 替换 result-chat-list 中的 assistant 消息

找到第 221-254 行的 result-chat-list 模板，替换为使用 MessageCard。

修改前：

<view v-if="resultMessages.length" class="result-chat-list">
  <view
    v-for="message in resultMessages"
    :key="message.id"
    class="chat-bubble"
    :class="{ user: message.role === 'user', system: message.role === 'assistant', pending: message.pending }"
  >
    <text selectable user-select>{{ getMessageDisplayContent(message) }}</text>
    <view v-if="message.pending" class="thinking-dots">
      <view></view>
      <view></view>
      <view></view>
    </view>
    <view
      v-if="isAssistantMessage(message)"
      class="message-toggle"
      @click.stop="toggleMessageCollapse(message)"
    >
      <text>{{ isMessageCollapsed(message) ? '展开' : '收起' }}</text>
      ...
    </view>
    <view v-if="isAssistantMessage(message)" class="message-actions">
      ...
    </view>
    <text class="bubble-time">{{ message.time }}</text>
  </view>
</view>

修改后：

<view v-if="resultMessages.length" class="result-chat-list">
  <view
    v-for="message in resultMessages"
    :key="message.id"
  >
    <MessageCard
      v-if="isAssistantMessage(message)"
      :content="message.content"
      :collapsed="isMessageCollapsed(message)"
      :content-length="message.content.length"
      :is-short-message="message.content.length < 100"
      :tts-icon="ttsPlayer.playing.value ? 'Ⅱ' : '▶'"
      :tts-text="ttsPlayer.playing.value ? '暂停' : '播放'"
      @toggle-collapse="toggleMessageCollapse(message)"
      @copy="copyMessageContent(message)"
      @change-direction="changeDirection"
      @not-like-me="notLikeMe"
      @continue="continueInChat"
      @play-tts="playMessageTts(message)"
    />
    <view v-else class="chat-bubble user">
      <text>{{ message.content }}</text>
      <text class="bubble-time">{{ message.time }}</text>
    </view>
  </view>
</view>

Step 4: 提交使用组件

cd "G:/IdeaProjects/emotion-museun"
git add mini-program/src/pages/main/ScriptView.vue
git commit -m "feat: ScriptView 复用 MessageCard 组件

- story-card 使用 MessageCard
- result-chat-list 中的 assistant 消息按内容长度自动切换短消息/完整卡片模式"

Task 3: 迁移并清理样式

Files:

Modify: mini-program/src/pages/main/ScriptView.vue
Step 1: 从 ScriptView.vue 中删除已迁移到 MessageCard 的样式

删除以下 CSS 类（从 <style scoped> 中移除）：

.story-card、.story-card.collapsed
.story-head、.story-head-actions、.story-title-wrap
.story-title、.tag-row、.tag
.collapse-icon、.copy-card-btn、.collapse-row
.collapse-chevron、.story-body、.story-body-scroll
.result-actions、.action-btn
.message-actions（上一轮临时添加的，不再使用）
.message-toggle（不再使用）

保留 ScriptView.vue 中仍然需要的样式，如：

.chat-bubble.user
.bubble-time
.result-chat-list
.thinking-dots
页面整体布局相关样式
Step 2: 验证样式清理后无遗漏

cd "G:/IdeaProjects/emotion-museun/mini-program"
npm run build:h5 2>&1 | tail -20

预期输出：DONE Build complete.

Step 3: 提交样式清理

cd "G:/IdeaProjects/emotion-museun"
git add mini-program/src/pages/main/ScriptView.vue
git commit -m "refactor: 迁移 story-card 相关样式到 MessageCard

删除 ScriptView.vue 中已迁移到 MessageCard 的样式类"

Task 4: 最终验证

Files:

无需修改文件，仅做验证
Step 1: 构建验证

cd "G:/IdeaProjects/emotion-museun/mini-program"
npm run build:h5 2>&1 | tail -20

预期输出：DONE Build complete.

Step 2: 功能验证（在 H5 浏览器中）

启动 H5 开发服务器并验证：

cd "G:/IdeaProjects/emotion-museun/mini-program"
npm run dev:h5

打开浏览器访问显示的端口（默认 http://localhost:5173），执行以下验证：

第一次生成故事：确认 story-card 样式、标题、标签、展开/收起、复制、功能按钮组均正常
重新生成（生成 script 类型长消息）：
- 内容 ≥ 100 字：显示与 story-card 完全一致的卡片样式
- 内容 < 100 字：显示简洁气泡，无任何功能按钮
普通聊天 assistant 消息：
- 内容 ≥ 100 字：显示完整卡片
- 内容 < 100 字：显示简洁气泡
用户消息：保持原有 .chat-bubble.user 样式不变
控制台：确认无 Vue 警告和 JavaScript 错误

Step 3: 提交验证结果（如有修复）

如果在验证中修复了问题，提交：

git add mini-program/src/components/MessageCard.vue mini-program/src/pages/main/ScriptView.vue
git commit -m "fix: 修复 MessageCard 组件验证中发现的问题

[描述具体修复内容]"

如果验证全部通过，无需额外提交。

自审检查

Spec 覆盖：
- ✅ 创建 MessageCard.vue 组件 → Task 1
- ✅ ScriptView.vue 复用组件 → Task 2
- ✅ 100 字阈值判断 → Task 2 (:is-short-message="message.content.length < 100")
- ✅ 样式迁移和清理 → Task 3
- ✅ 验证 → Task 4
无占位符： 计划中没有 TBD/TODO
类型一致： props 名称 contentLength 与模板中使用一致，事件名称在组件和父组件中一致
