Vue 实现好友分享功能

实现好友分享功能通常需要结合前端Vue框架和后端API，以下是一个完整的实现方案：

前端实现

在Vue组件中创建分享按钮和分享面板：

<template>
  <div>
    <button @click="showSharePanel = true">分享给好友</button>

    <div v-if="showSharePanel" class="share-panel">
      <input v-model="searchQuery" placeholder="搜索好友"/>
      <button @click="searchFriends">搜索</button>

      <div v-for="friend in filteredFriends" :key="friend.id">
        <span>{{ friend.name }}</span>
        <button @click="shareWithFriend(friend.id)">分享</button>
      </div>
    </div>
  </div>
</template>

数据和方法实现

<script>
export default {
  data() {
    return {
      showSharePanel: false,
      searchQuery: '',
      allFriends: [],
      filteredFriends: []
    }
  },
  methods: {
    async fetchFriends() {
      try {
        const response = await axios.get('/api/friends');
        this.allFriends = response.data;
        this.filteredFriends = [...this.allFriends];
      } catch (error) {
        console.error('获取好友列表失败:', error);
      }
    },
    searchFriends() {
      if (!this.searchQuery) {
        this.filteredFriends = [...this.allFriends];
        return;
      }
      this.filteredFriends = this.allFriends.filter(friend => 
        friend.name.toLowerCase().includes(this.searchQuery.toLowerCase())
      );
    },
    async shareWithFriend(friendId) {
      try {
        await axios.post('/api/share', {
          friendId,
          contentId: this.$route.params.id // 假设分享的是当前页面内容
        });
        alert('分享成功');
        this.showSharePanel = false;
      } catch (error) {
        console.error('分享失败:', error);
      }
    }
  },
  mounted() {
    this.fetchFriends();
  }
}
</script>

后端API实现

Node.js示例实现分享API：

// 获取好友列表
router.get('/api/friends', async (req, res) => {
  const userId = req.user.id; // 从认证中获取用户ID
  const friends = await FriendModel.find({ userId });
  res.json(friends);
});

// 分享内容
router.post('/api/share', async (req, res) => {
  const { friendId, contentId } = req.body;

  // 创建分享记录
  const share = new ShareModel({
    sender: req.user.id,
    receiver: friendId,
    contentId,
    sharedAt: new Date()
  });

  await share.save();

  // 这里可以添加通知逻辑，如发送邮件或推送

  res.json({ success: true });
});

分享功能扩展

实现多种分享方式：

// 添加社交平台分享
shareToSocial(platform) {
  let url = '';
  const currentUrl = encodeURIComponent(window.location.href);

  switch(platform) {
    case 'wechat':
      url = `wechat://share?url=${currentUrl}`;
      break;
    case 'qq':
      url = `http://connect.qq.com/widget/shareqq/index.html?url=${currentUrl}`;
      break;
    case 'weibo':
      url = `http://service.weibo.com/share/share.php?url=${currentUrl}`;
      break;
  }

  window.open(url, '_blank');
}

样式优化

添加基础样式提升用户体验：

.share-panel {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  padding: 20px;
  background: white;
  box-shadow: 0 0 10px rgba(0,0,0,0.1);
  z-index: 1000;
}

.share-panel input {
  padding: 8px;
  margin-right: 10px;
}
