-### 2. 使用分享组件
-
-```vue
-<template>
-  <view>
-    <share-actions 
-      @save="handleSave"
-      :show-save="true"
-      :show-share="true"
-      save-text="保存图片"
-      share-text="分享微信"
-    />
-  </view>
-</template>
-
-<script setup>
-import { saveImageToAlbum, createShareMessage } from '@/utils/share'
-import shareActions from '@/components/share-actions.vue'
-
-// 保存图片
-async function handleSave() {
-  const imagePath = 'https://example.com/image.jpg'
-  await saveImageToAlbum(imagePath)
-}
-
-// 分享配置
-function onShareAppMessage() {
-  return createShareMessage({
-    title: '分享标题',
-    path: '/pages/index/index'
-  })
-}
-
-defineExpose({
-  onShareAppMessage
-})
-</script>
-```
-
-### 3. 保存二维码图片
-
-```vue
-<template>
-  <view>
-    <uqrcode ref="qrcode" canvasId="qrcode" :value="qrcodeUrl" />
-    <button @click="saveQrcode">保存二维码</button>
-  </view>
-</template>
-
-<script setup>
-import { ref } from 'vue'
-import { saveImageToAlbum } from '@/utils/share'
-import { toast } from '@/utils/widget'
-
-const qrcode = ref(null)
-const qrcodeUrl = ref('https://example.com')
-
-async function saveQrcode() {
-  try {
-    if (!qrcode.value) {
-      toast('二维码未加载完成')
-      return
-    }
-    
-    // 获取二维码临时文件路径
-    const tempFilePath = qrcode.value.toTempFilePath()
-    if (tempFilePath) {
-      await saveImageToAlbum(tempFilePath)
-    } else {
-      toast('获取二维码失败')
-    }
-  } catch (err) {
-    console.error('保存失败:', err)
-    toast('保存失败')
-  }
-}
-</script>
-```
-
-### 4. 动态分享内容
-
-```vue
-<script setup>
-import { ref, computed } from 'vue'
-import { createShareMessage } from '@/utils/share'
-
-const currentItem = ref({
-  id: '123',
-  title: '商品标题',
-  image: 'https://example.com/product.jpg'
-})
-
-// 动态生成分享配置
-function onShareAppMessage() {
-  return createShareMessage({
-    title: currentItem.value.title,
-    path: `/pages/detail/detail?id=${currentItem.value.id}`,
-    imageUrl: currentItem.value.image
-  })
-}
-
-defineExpose({
-  onShareAppMessage
-})
-</script>
-```
-
-## 配置说明
-
-### 1. 启用分享到朋友圈
-
-在 `pages.json` 中配置页面：
-
-```json
-{
-  "path": "pages/index/index",
-  "style": {
-    "navigationBarTitleText": "首页",
-    "enableShareTimeline": true
-  }
-}
-```
-
-### 2. 全局分享配置
-
-在 `App.vue` 中配置全局分享：
-
-```vue
-<script>
-export default {
-  onShareAppMessage() {
-    return {
-      title: '默认分享标题',
-      path: '/pages/index/index'
-    }
-  },
-  onShareTimeline() {
-    return {
-      title: '默认朋友圈标题'
-    }
-  }
-}
-</script>
-```
-
-## API 说明
