如数据库中数据,我已知url的数组
"url":["cloud://abc123.png","cloud://dsa789.png","cloud://bnm987.png"]
将url数据中对应的tip值修改成"tip":"许"
该怎么写云函数呢?
// 小程序端 wx.cloud.init() wx.cloud.callFunction({ name:'云函数名', data:{ tip:'许', urls:["cloud://abc123.png","cloud://dsa789.png","cloud://bnm987.png"] } }).then(res=>console.log(res)) .catch(res=>console.error(res)) // ================================================================ // 云函数 const cloud = require('wx-server-sdk') cloud.init() const db = cloud.database({ env: '环境ID' }) const _ = db.command // 云函数入口函数 exports.main = async(event, context) => { var p1 = db.collection('xxxxx').where({ '_group1.url':_.in(event.urls) }).update({ data: { '_group1.$.tip':event.tip } }), p2 = db.collection('xxxxx').where({ '_group2.url':_.in(event.urls) }) .update({ data: { '_group2.$.tip':event.tip } }) return Promise.all([p1,p2]) }
