出现的问题是3个数据在数组imgArr，filelist只能获得1个，是不是我的写法有问题，求大佬

代码如下：

senEmail_new(){
  var that = this;
  let promiseArr = []
  for (let i=0 ,len=this.data.imgArr.length; i<len; i++){
  let p = new Promise((resolve,reject)=>{
  //var that = this;
  const filePath = this.data.imgArr[i].path//定义文件地址
  const filename = this.data.imgArr[i].name//文件名
  const cloudPath = 'user_file/'+Math.random()+filename.match(/\.[^.]+?$/)[0]
  const imageIDNow = that.data.filelist;
    wx.cloud.uploadFile({
      cloudPath,//云存储地址
      filePath,//文件地址
      success: res => {
        console.log('上传成功',i,res)
        imageIDNow = imageIDNow.concat(res.fileID);
        //app.globalData.fileID = res.fileID
        that.setData({
          filelist: imageIDNow,//定义文件data
        })
        //resolve()
          wx.showToast({//上传成功图标
            title: "成功", // 提示的内容
            icon: "success", // 图标，默认success
            image: "", // 自定义图标的本地路径，image 的优先级高于 icon
            duration: 2000, // 提示的延迟时间，默认1500
            mask: false, // 是否显示透明蒙层，防止触摸穿透
            success: function () {
            },
            fail: function () {
                console.log("上传失败");
            },
            complete: function () {
                console.log("");
            }
        })
        //that.getTempFileURL()
      },
      fail(err){
        console.log(err)
        reject()
      },
      complete:function(){
        resolve()
      }
    })
  })
  promiseArr .push(p)
  }
  //获取下载链接
  Promise.all(promiseArr).then((res)=>{
    var that = this;
    for(let j=0 ,lenl=this.data.filelist.length; j<lenl; j++){
      const fileList_1 = that.data.filelist[j];
      //const downloudPathNow = that.data.downloudPath;
      wx.cloud.getTempFileURL({
        fileList: [fileList_1],
        success: res => {
          console.log('成功获取地址',j,res.fileList[0].tempFileURL)
          that.setData({
            downloudPath:res.fileList[0].tempFileURL
          })
        },
        fail(err){
          console.log('失败',err)
        }
      })
    }
  })
},
