有木有学姐，帮解答下云数据库中id值中option用法；官方文档上没得

// 调取云数据库中的商品信息
const db = wx.cloud.database();
var that = this;
await db.collection('services').doc(${options.category + options.id}).get().then(res => {
that.setData({
goodsInfo: res.data
})
})

let fileList = [];
this.data.goodsInfo.serviceImg.forEach((item) => {
  fileList.push({
    fileID: `cloud://test-koevi.7465-test-koevi-1306666298/services/${options.category}/id/${options.id}/${item}`,
    maxAge: 70 * 70 // one hour
  })
})

学姐木有，答案也木有
