      { id: 'cs2', label: '联系售后客服' },
      { id: 'cs3', label: '联系VIP客服' },
    ],
  },
  // 点击事件
  handleContact(e) {
    const customerId = e.currentTarget.dataset.id; // 获取按钮绑定的客服ID
    wx.request({
      url: 'https://your-backend-service/api/getCustomerServiceUrl',
      method: 'POST',
      data: { customerId },
      success: (res) => {
        if (res.data.success) {
          // 跳转到生成的客服链接
          wx.navigateTo({ url: res.data.url });
        } else {
          wx.showToast({ title: '客服连接失败', icon: 'none' });
        }
      },
    });
  },
});

<view class="contact-buttons">
  <button
    wx:for="{{buttons}}"
    wx:key="id"
    data-id="{{item.id}}"
    bindtap="handleContact"
  >
    {{item.label}}
  </button>
</view>

const express = require('express');
const app = express();
app.use(express.json());

// 客服配置映射
const customerServiceMapping = {
  cs1: { name: '售前客服', wechatId: 'wx12345', link: '/pages/service1' },
  cs2: { name: '售后客服', wechatId: 'wx67890', link: '/pages/service2' },
  cs3: { name: 'VIP客服', wechatId: 'wx54321', link: '/pages/service3' },
};

app.post('/api/getCustomerServiceUrl', (req, res) => {
  const { customerId } = req.body;

  // 查询客服配置
  const customerService = customerServiceMapping[customerId];
  if (customerService) {
    res.json({
      success: true,
      url: customerService.link, // 返回指定客服链接
    });
  } else {
    res.status(404).json({
      success: false,
      message: '客服ID无效',
    });
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

const axios = require('axios');

async function generateCustomerServiceLink(customerId, userId) {
  const token = 'YOUR_ACCESS_TOKEN'; // 微信接口的Access Token
  const response = await axios.post(
    `https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=${token}`,
    {
      touser: userId,
      msgtype: 'text',
      text: { content: `您好！您正在与${customerId}客服连接中。` },
    }
  );
  return response.data;
}
