云函数 await 什么情况 会 return undefined？困惑
async function getMessageName(tid) { message.where({ templateid: tid }).get().then(res => { console.log(res.data) if (res.data) { let sendData = [] for (let i in res.data) { let oneData = { touser: res.data[i].subscriber, templateId: tid, miniprogram_state: 'developer', page: 'pages/index/index', // 此处字段应修改为所申请模板所要求的字段 data: res.data[i].messageItem } sendData.push(oneData) } console.log('sendData:') console.log(...sendData) return sendData // return "here is the return" } }).catch(err => { console.log(err) }) } async function aaa(tid) { return "here is the return" } async function sendSubscribeMessage(event) { console.log("here i am") let prepareData = await aaa(event.templateId) console.log(prepareData) // 这句 是 "here is the return" prepareData = await getMessageName(event.templateId) console.log(prepareData) // 这句 是 undefined console.log("here i am 2") let sendResult = [] for (let i in prepareData) { sendResult.push(await cloud.openapi.subscribeMessage.send(prepareData[i])) console.log("here i am 3") } return sendResult } 下面是云函数本地调试的 Console提示 [info] 函数被触发，正在执行中... index.js:17 {action: "sendSubscribeMessage", templateId: "txPkadLVHO4lWYSPd_y01YH9go0P2FE8AHIdt6nMno4", datat: {…}} index.js:91 here i am index.js:93 here is the return index.js:95 undefined index.js:96 here i am 2 node.js:1 [info] 函数执行成功（耗时 15ms） [] node.js:1 [info] 调用 本地 云函数 'openapi' 完成 （耗时 19ms） index.js:42 (2) [{…}, {…}] index.js:58 sendData: index.js:59 {touser: "ojFQH5ttjBG8QPnE-xgbvIj763xg", templateId: "txPkadLVHO4lWYSPd_y01YH9go0P2FE8AHIdt6nMno4", miniprogram_state: "developer", page: "pages/index/index", data: {…}} {touser: "ojFQH5uc10PCwpS48EzU-jykyV94", templateId: "txPkadLVHO4lWYSPd_y01YH9go0P2FE8AHIdt6nMno4", miniprogram_state: "developer", page: "pages/index/index", data: {…}}
