之前有另一个云函数整理数据库的文件，已打印验证之前那个云函数没问题，大概1300行10列左右的数据 现在这个excel云函数用来读然后存到excel里， 之后要上传到云存储 问题就是出现在excel云函数读完数据存不下来， 但不知道是数 报错： 11/08 23:00:07:821 [excel][1] ERROR RequestId: b5df872c-7e96-43f3-8b15-30a6078d380f Result: TypeError: Cannot read property '0' of undefined at exports.main (/var/user/index.js:39:49) at IncomingMessage.<anonymous> (/data/scf/frame/node12/runtime.js:246:26) at IncomingMessage.emit (events.js:323:22) at endReadableNT (_stream_readable.js:1204:12) at processTicksAndRejections (internal/process/task_queues.js:84:21) excel云函数代码： // 云函数入口文件 const cloud = require('wx-server-sdk') const moment = require("moment-timezone") cloud.init({    traceUser: true,   env: cloud.DYNAMIC_CURRENT_ENV }) // 使用当前云环境 //操作excel用的类库 const xlsx = require('xlsx'); // 云函数入口函数 exports.main = async(event, context) => {     let {userdata} = event            // javascript date     //  console.log(new Date()); // 2021-03-16T08:04:07.441Z (UTC+0     //  console.log(moment().tz("Asia/Shanghai").format()); // 2021-03-16T16:04:07+08:00 (UTC+8)     let curDate = moment().tz("Asia/Shanghai").format('YYYYMMDDHHmmss');     //let curDate =new Date().toISOString()     //1,定义excel表格名     let dataCVS = 'xiaofu101_order_list_'+curDate+'.xlsx'     //2，定义存储数据的     let alldata = [];     //let row = ['status','receiver']; //表属性     let row=['_id' , 'orderDate', 'region','address','receiver','phone'     ,'SchoolName','cloth_id','cloth_notes','num','cloth_price','totalPrice','status']     alldata.push(row);     console.log('excel before loop:'+alldata)     let count = 0     for (let key in userdata) {       for (let i in userdata[key]['product']){         let arr = [];         arr.push(userdata[key]._id);         arr.push(userdata[key].orderDate);         arr.push(userdata[key]['address'].region[0]+'-'         +userdata[key]['address'].region[1]+'-'         +userdata[key]['address'].region[2]);         arr.push(userdata[key]['address'].address);         arr.push(userdata[key]['address'].receiver);         arr.push(userdata[key]['address'].phone);         arr.push(userdata[key].curSchoolName);         arr.push(userdata[key]['product'][i].cloth_id);         arr.push(userdata[key]['product'][i].cloth_notes);         arr.push(userdata[key]['product'][i].cloth_price);         arr.push(userdata[key]['product'][i].num);         arr.push(userdata[key].totalPrice);         arr.push(userdata[key].status);         alldata.push(arr)                }       count += 1       console.log(count)     }     console.log('excel has data:'+alldata)     //3，把数据保存到excel里     const buffer = xlsx.utils.book_new();     const worksheet = xlsx.utils.aoa_to_sheet(alldata);     xlsx.utils.book_append_sheet(buffer, worksheet, 'mySheetName');     const excelBuffer = xlsx.write(buffer, { type: 'buffer' });     console.log('buffer has data : ', excelBuffer);     //4，把excel文件保存到云存储里     console.log(dataCVS)     return await cloud.uploadFile({       cloudPath: dataCVS,       fileContent: excelBuffer, //excel二进制文件            }) } 这条语句没有执行打印出来， console.log('excel has data:'+alldata)  console.log(count)打印出来了 说明错可能是在上面 alldata.push(arr) 但不知道是保存的数据类型造成的property '0' of undefined还是怎么回事， 请问怎么同时调式2个云函数，现在只能调式1个excel云函数，不能模拟传数据库数据的情况

[图片] 这是什么原因 是因为是国外ip吗？ 那人在国外维护国内小程序 那怎么才能导出？

[图片] 2年没登了 远程push github 出问题，已经检查了 设置->网络和认证里的用户名密码是对的 [图片] 难道是版本问题？现在还有个问题开发工具下载的更新无法安装 [图片]

关于为了避免用户取消“获取地址”之后无法再打开，我看教程说是用opensetting(). https://www.bilibili.com/video/BV1y7411z7hQ?p=85 但是代码一样还是没用。我用openSetting()怎么还打不开设置，不知道哪错了. 点取消授权，再点button， console确实输出我故意打印的“取消”了但并没有打开设置。 WXML:         获取收货地址    JS. handleChooseAddress(){       wx.getSetting({       success: (result) => {        // console.log(result);         const scopeAddress=result.authSetting["scope.address"];         if (scopeAddress===true||scopeAddress===undefined){           //console.log(result);           wx.chooseAddress({             success: (result1) => {               console.log(result1);             }           });         }else{ console.log("取消");           wx.openSetting({             success: (result2) => {               wx.chooseAddress({                 success: (result3) => {                   console.log(result3);                 }               });              }           });         }       }     })   } 另一种写法还是不对 ： 报错：errMsg: "openSetting:fail errcode 1"} /* Promise形式 getSetting */ export const getSetting=()=>{   return new Promise((resolve,reject)=>{     wx.getSetting({       withSubscriptions: true,       success: (result)=>{         resolve(result);       },       fail:(err)=>{         reject(err);       }     });     }) } /* Promise形式 chooseAddress */ export const chooseAddress=()=>{   return new Promise((resolve,reject)=>{     wx.chooseAddress({       withSubscriptions: true,       success: (result)=>{         resolve(result);       },       fail:(err)=>{         reject(err);       }     });     }) } /* Promise形式 openSetting */ export const openSetting=()=>{   return new Promise((resolve,reject)=>{     wx.openSetting({       withSubscriptions: true,       success: (result)=>{         resolve(result);       },       fail:(err)=>{         reject(err);       }     });     }) } // pages/cart/index.js import{getSetting,chooseAddress,openSetting } from "../../utils/asyncWx.js"; import regeneratorRuntime from '../../lib/runtime/runtime'; Page({   /**    * 页面的初始数据    */   data: {   },        async handleChooseAddress(){       try {           /*              wx.getSetting({               success: (result) => {                 // console.log(result);                 const scopeAddress=result.authSetting["scope.address"];                 if (scopeAddress===true||scopeAddress===undefined){                   //console.log(result);                   wx.chooseAddress({                     success: (result1) => {                       console.log(result1);                     }                   });                 }else{                   console.log("取消");                   wx.openSetting({                     success: (result2) => {                       wx.chooseAddress({                         success: (result3) => {                           console.log(result3);                         }                       });                       }                   });                 }               },               fail:()=>{},               complete:()=>{}             });           */                      const res1=await getSetting();             const scopeAddress=res1.authSetting["scope.address"];             if (scopeAddress===false){               await openSetting();             }             const res2=await chooseAddress();             console.log(res2);           }  catch (error) {             console.log(error);           }     }    })
