本来写完的项目 复制了份代码 云数据库 也复制了 云函数啥的都复制了一份 导入改好appid后 把环境ID也改好了 写测试demo也能正常访问数据库 云函数也写了demo能正常使用

但是前面的云函数就调用失败

云函数代码

// 云函数入口文件
const cloud = require('wx-server-sdk')

cloud.init()

const db = cloud.database()
const $ = db.command.aggregate
const _ = db.command

// 云函数入口函数
exports.main = async (event, context) => {
    const wxContext = cloud.getWXContext()
    let location = event.location
    let maxDistance = event.maxDistance
    
    let bdata,cdata=[]
    let adata=[]
    let type = event.type
    let postdata = []

    if(type=="recommend"){
        postdata = await db.collection('recruiter_post_lease').aggregate().match({
            _id:_.in(event.a),
            status:'doing'
        }).lookup({
            from:'find_servicer',
            localField: '_openid',
            foreignField: '_openid',
            as:'pInfo'
        }).unwind('$pInfo').lookup({
            from:'find_companysInfo',
            localField:'pInfo.companyID',
            foreignField:'_id',
            as:'cInfo'
        }).unwind('$cInfo').addFields({
            location:"$cInfo.location"
        }).limit(100)
        .end().then(res => {return res.list})
    }else if(type=="time"){
        postdata = await db.collection('recruiter_post_lease').aggregate().match({
            status:'doing'
        }).sort({
            createTime:-1
        }).lookup({
            from:'find_servicer',
            localField: '_openid',
            foreignField: '_openid',
            as:'pInfo'
        }).unwind('$pInfo').lookup({
            from:'find_companysInfo',
            localField:'pInfo.companyID',
            foreignField:'_id',
            as:'cInfo'
        }).unwind('$cInfo').addFields({
            location:"$cInfo.location"
        }).limit(100)
        .end().then(res => {return res.list})
    }
    
    postdata.forEach(el => {
        if(el.pInfo.status == '审核通过'){
            adata.push(el)
        }
    })

    if(maxDistance){
        await db.collection('recruiter_post_lease').aggregate()
        .geoNear({
            distanceField: 'distance', 
            spherical: true,
            near: location,
            maxDistance:maxDistance
        }).end().then(res => {bdata=res.list})
    }else{
        await db.collection('recruiter_post_lease').aggregate()
        .geoNear({
            distanceField: 'distance', 
            spherical: true,
            near: location,
        }).end().then(res => {bdata=res.list})
    }
    adata.forEach(element => {
        bdata.forEach(another => {
            if(element._id == another._id){
                let distance = another.distance/1000 
                let ddata = { 
                    element, 
                    distance:distance.toFixed(1) 
                } 
                cdata.push(ddata)
            }
        })
    })
    return {
        postdata:cdata
    }
}

js调用代码

  getPostdata3:function(type){
    wx.showLoading({
      title: '数据快到啦',
    })
    let lct = this.data.userLocation
    
    wx.cloud.callFunction({
      name:'getClosePostdata_3',
      data:{
        //传过去的这三个都是有数据的
        a:this.data.Recommend,
        type:type,
        location:db.Geo.Point(lct.longitude,lct.latitude)
      },
      success: res =>{
        this.setData({
          postData:res.result.postdata
        })
        wx.setStorage({
          data: res.result.postdata,
          key: 'postdatas',
        })
        wx.hideLoading()
      },
      fail: err =>{
        console.log('获取失败:'+err)   
        wx.hideLoading()
      }
    })
  },
