§ 5 · Domain Knowledge
Database Best Practices
Schema Design:
{
_id: "auto-generated",
userId: "user_openid",
title: "任务标题",
status: "pending",
priority: 1,
tags: ["工作", "紧急"],
createdAt: db.serverDate()
}
Index Strategy:
db.collection('orders').createIndex({
userId: 1,
status: 1,
createdAt: -1
})
Cloud Function Patterns
const cloud = require('wx-server-sdk')
cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV })
const db = cloud.database()
exports.main = async (event, context) => {
const { action, data } = event
const { OPENID } = cloud.getWXContext()
try {
switch(action) {
case 'create': return await createItem(data, OPENID)
case 'query': return await queryItems(data, OPENID)
default: throw new Error(`Unknown action: ${action}`)
}
} catch (err) {
return { success: false, error: err.message }
}
}
Security Best Practices
Database Rules:
{
"read": "doc.userId == auth.openid",
"write": "doc.userId == auth.openid"
}
Authentication:
const { OPENID } = cloud.getWXContext()
if (!OPENID) throw new Error('Unauthorized')

§ 7 · Standards & Reference
See references/07-standards.md for detailed:
- SDK installation guide
- Database operations (CRUD, aggregation, transactions)
- File storage operations
- Cloud function patterns
- Security best practices
Quick Example: Todo应用
云函数:
exports.main = async (event, context) => {
const { action, data } = event
const { OPENID } = cloud.getWXContext()
const db = cloud.database()
switch(action) {
case 'list':
return await db.collection('todos')
.where({ userId: OPENID })
.orderBy('createdAt', 'desc')
.get()
case 'create':
return await db.collection('todos').add({
data: { ...data, userId: OPENID, createdAt: db.serverDate() }
})
case 'toggle':
const todo = await db.collection('todos').doc(data.id).get()
return await db.collection('todos').doc(data.id).({
: { : !todo.. }
})
}
}
小程序端:
Page({
data: { todos: [] },
async loadTodos() {
const { result } = await wx.cloud.callFunction({
name: 'todo',
data: { action: 'list' }
})
this.setData({ todos: result.data })
}
})
