# 三、云函数代码框架

在 `uniCloud/cloudfunctions/` 目录下创建以下云函数。

## 1. login（微信登录）

```javascript
// uniCloud/cloudfunctions/login/index.js
const db = uniCloud.database()

exports.main = async (event, context) => {
  const { code, userInfo } = event
  
  try {
    // 1. 获取openid

    if (!OPENID) {
      return { code: -1, message: '获取openid失败' }
    }
    
    // 2. 查询或创建用户
    const userCollection = db.collection('users')
    let user = await userCollection.where({ wx_openid: OPENID }).get()
    
    let userId
    if (user.data.length === 0) {

  }
}

// 辅助方法
function getScheduleTitle(data) {
  const titles = {
    vaccine: `${data.vaccineName || '疫苗'}接种`,
    deworm: `${data.brand || ''}驱虫`,
    checkup: '体检',
    medical: '复查'
  }
  return titles[data.type] || '健康提醒'
}
```

## 4. scheduleManager（日程管理）

```javascript
// uniCloud/cloudfunctions/scheduleManager/index.js
const db = uniCloud.database()

exports.main = async (event, context) => {
  const { action, data, scheduleId, petId } = event
  const { uid } = context
  
  const scheduleCollection = db.collection('schedules')
  const now = Date.now()
  
  try {
    switch (action) {
      case 'create': {
        const res = await scheduleCollection.add({
          ...data,
          user_id: uid,
          status: 'pending',
          createdAt: now,
          updatedAt: now
        })
        return { code: 0, data: { id: res.id } }
      }
      
      case 'list': {
        let where = { user_id: uid }
        if (petId) where.pet_id = petId
        
        const res = await scheduleCollection.where(where)
          .orderBy('scheduledDate', 'asc')
          .get()
        return { code: 0, data: res.data }
      }
      
      case 'today': {
        // 获取今日及逾期的日程
        const startOfDay = new Date().setHours(0, 0, 0, 0)
        const endOfDay = new Date().setHours(23, 59, 59, 999)
        
        const res = await scheduleCollection.where({
          user_id: uid,
          status: db.command.in(['pending', 'overdue']),
          scheduledDate: db.command.lte(endOfDay)
        }).orderBy('scheduledDate', 'asc').get()
        
        return { code: 0, data: res.data }
      }
      
      case 'upcoming': {
        // 获取未来7天的日程
        const endOfWeek = now + 7 * 24 * 60 * 60 * 1000
        
        const res = await scheduleCollection.where({
          user_id: uid,
          status: 'pending',
          scheduledDate: db.command.gte(now).and(db.command.lte(endOfWeek))
        }).orderBy('scheduledDate', 'asc').get()
        
        return { code: 0, data: res.data }
      }
      
      case 'complete': {
        await scheduleCollection.doc(scheduleId).update({
          status: 'completed',
          updatedAt: now
        })
        return { code: 0, message: '已完成' }
      }
      
      case 'postpone': {
        const { days } = data
        const schedule = await scheduleCollection.doc(scheduleId).get()
        const newDate = schedule.data[0].scheduledDate + days * 24 * 60 * 60 * 1000
        
        await scheduleCollection.doc(scheduleId).update({
          scheduledDate: newDate,
          status: 'pending',
          updatedAt: now
        })
        return { code: 0, message: `已推迟${days}天` }
      }
      
      case 'skip': {
        await scheduleCollection.doc(scheduleId).update({
          status: 'skipped',
          updatedAt: now
        })
        return { code: 0, message: '已忽略' }
      }
      
      case 'delete': {
        await scheduleCollection.doc(scheduleId).remove()
        return { code: 0, message: '删除成功' }
      }
      
      default:
        return { code: -1, message: '未知操作' }
    }
  } catch (err) {
    return { code: -1, message: err.message }
  }
}
```

## 5. reminderPush（定时提醒触发器）

```javascript
// uniCloud/cloudfunctions/reminderPush/index.js
// 配置：在uniCloud后台设置定时触发器，每天上午9:00执行

const db = uniCloud.database()

exports.main = async (event, context) => {
  const now = Date.now()
  const today = new Date()
  today.setHours(0, 0, 0, 0)
  const tomorrow = today.getTime() + 24 * 60 * 60 * 1000
  
  try {
    const scheduleCollection = db.collection('schedules')
    const userCollection = db.collection('users')
    
    // 1. 标记逾期
    await scheduleCollection.where({
      status: 'pending',
      scheduledDate: db.command.lt(today)
    }).update({
      status: 'overdue',
      updatedAt: now
    })
    
    // 2. 查找今天需要提醒的日程
    // 提醒逻辑：在 reminderDays 中的某一天，且今天就是提醒日
    const schedules = await scheduleCollection.where({
      status: db.command.in(['pending', 'overdue']),
      scheduledDate: db.command.gte(today).and(db.command.lt(tomorrow + 7 * 24 * 60 * 60 * 1000))
    }).get()
    
    // 3. 按用户分组，批量发送订阅消息
    const userSchedules = {}
    schedules.data.forEach(s => {
      if (!userSchedules[s.user_id]) {
        userSchedules[s.user_id] = []
      }
      userSchedules[s.user_id].push(s)
    })
    
    for (const userId in userSchedules) {
      const user = await userCollection.doc(userId).get()
      const openid = user.data[0]?.wx_openid
      
      if (!openid) continue
      
      // 获取该用户今天需要提醒的日程
      const todaySchedules = userSchedules[userId].filter(s => {
        const scheduledDate = new Date(s.scheduledDate)
        scheduledDate.setHours(0, 0, 0, 0)
        const diffDays = Math.ceil((scheduledDate - today) / (24 * 60 * 60 * 1000))
        return s.reminderDays.includes(diffDays) && diffDays >= 0
      })
      
      if (todaySchedules.length === 0) continue
      
      // 构建订阅消息（需先在微信公众平台申请模板）
      const templateId = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' // 你的模板ID
      
      for (const schedule of todaySchedules) {
        try {
          await uniCloud.openapi.weixin.subscribeMessage.send({
            touser: openid,
            templateId: templateId,
            page: `pages/schedule/list?petId=${schedule.pet_id}`,
            data: {
              thing1: { value: schedule.title },           // 事项
              time2: { value: formatDate(schedule.scheduledDate) }, // 时间
              thing3: { value: schedule.status === 'overdue' ? '已逾期，请尽快处理' : '即将到期' } // 备注
            },
            miniprogramState: 'formal'
          })
          
          // 更新最后提醒时间
          await scheduleCollection.doc(schedule._id).update({
            lastRemindedAt: now
          })
        } catch (err) {
          console.error(`发送失败: ${userId}`, err)
        }
      }
    }
    
    return {
      code: 0,
      message: '提醒处理完成',
      data: {
        totalChecked: schedules.data.length,
        notifiedUsers: Object.keys(userSchedules).length
      }
    }
  } catch (err) {
    return { code: -1, message: err.message }
  }
}

function formatDate(timestamp) {
  const d = new Date(timestamp)
  return `${d.getFullYear()}年${d.getMonth() + 1}月${d.getDate()}日`
}
```

**定时触发器配置**（在 `reminderPush` 云函数的 `package.json` 中）：

```json
{
  "name": "reminderPush",
  "version": "1.0.0",
  "description": "每日健康提醒推送",
  "main": "index.js",
  "extensions": {
    "uni-cloud-jql": {}
  },
  "cloudfunction-config": {
    "concurrency": 1,
    "triggers": [
      {
        "name": "dailyReminder",
        "type": "timer",
        "config": "0 0 9 * * * *"
      }
    ]
  }
}
```

> 说明：`0 0 9 * * * *` 表示每天上午9:00执行（UTC+8 时区）。

## 6. nearbyHospitals（附近医院查询）

```javascript
// uniCloud/cloudfunctions/nearbyHospitals/index.js
const db = uniCloud.database()

exports.main = async (event, context) => {
  const { longitude, latitude, maxDistance = 5000, limit = 20 } = event
  // maxDistance 单位：米，默认5km
  
  try {
    const hospitalCollection = db.collection('hospitals')
    
    const res = await hospitalCollection.where({
      status: 'active',
      location: db.command.geoNear({
        geometry: db.Geo.Point(longitude, latitude),
        maxDistance: maxDistance,
        distanceField: 'distance'
      })
    }).limit(limit).get()
    
    // 格式化距离
    const hospitals = res.data.map(h => ({
      ...h,
      distance: h.distance ? Math.round(h.distance) : null,
      distanceText: h.distance 
        ? (h.distance < 1000 ? `${Math.round(h.distance)}m` : `${(h.distance / 1000).toFixed(1)}km`)
        : '未知'
    }))
    
    return {
      code: 0,
      data: hospitals
    }
  } catch (err) {
    return { code: -1, message: err.message }
  }
}
```

# 四、关键配置补充

## 1. 地理位置索引（必须）

在 uniCloud 控制台 → 数据库 → `hospitals` 集合 → 索引管理，创建：

```json
{
  "location": "2dsphere"
}
```

## 2. manifest.json 小程序配置

```json
{
  "mp-weixin": {
    "appid": "你的小程序appid",
    "setting": {
      "urlCheck": false
    },
    "permission": {
      "scope.userLocation": {
        "desc": "你的位置信息将用于查找附近宠物医院"
      }
    },
    "requiredPrivateInfos": [
      "getLocation"
    ]
  }
}
```

## 3. 云存储目录规划

```
cloudstorage/
├── pet-avatars/          # 宠物头像
├── record-images/        # 病历/疫苗证照片
├── article-covers/       # 百科文章封面
└── share-cards/          # 生成的分享卡片
```

---

这套框架覆盖了 **MVP 阶段 90% 的核心功能**。建议你先实现 **login → petCrud → recordCrud → scheduleManager → reminderPush** 这个主线，跑通"创建宠物 → 记录疫苗 → 生成提醒 → 推送通知"的完整闭环，再逐步扩展发现页和会员功能。

需要我针对某个具体模块（如**微信支付开通会员**、**订阅消息授权引导**、**图片上传云存储**）继续展开吗？
