云函数index

// 云函数入口文件

const cloud = require('wx-server-sdk')

cloud.init()

const db = cloud.database()

const _ = db.command

exports.main = async (event, context) => {

// console.log('collectionName is :' + event.collectionName)

var whereObjects = event.whereObjects

var updateObjects = event.updateObjects

var collectionName = event.collectionName

console.log(whereObjects)

try {

return await db.collection(collectionName).where(whereObjects)

.update({

data: updateObjects,

})

} catch (e) {

console.log('whereObjects is :' + whereObjects)

console.error(e)

}

}

本地调用函数获取到的whereObjects中获取到的对象的值为undefined时，整个表中相应的字段全部修改
