两个云函数有一个调用成功，另一个报错，下面为调用失败的云函数。 // 云函数入口文件 const cloud = require('wx-server-sdk') cloud.init() // 云函数入口函数 const db = cloud.database() const MAX_LIMIT = 100 exports.main = async (event, context) => { const new_name = event.a // 先取出集合记录总数 const countResult = await db.collection(new_name).count() const total = countResult.total // 计算需分几次取 const batchTimes = Math.ceil(total / 100) // 承载所有读操作的 promise 的数组 const tasks = [] for (let i = 0; i < batchTimes; i++) { const promise = db.collection(new_name).skip(i * MAX_LIMIT).limit(MAX_LIMIT).get() tasks.push(promise) } // 等待所有 return (await Promise.all(tasks)).reduce((acc, cur) => { return { data: acc.data.concat(cur.data), errMsg: acc.errMsg, } }) } wx.cloud.callFunction({ name:'tichu', data: { a: 'allplayers' }, success: res => { console.log(res) }, fail :err => {console.log(err)} }); /* 捕获的错误为 Error: cloud.callFunction:fail Error: errCode: -504002 functions execute fail | errMsg: Error: collection.count:fail -501003 exceed request limit.
