  如果按照我视频中的思路的话，是先上传图片到云存储，然后再把数据存到云数据库。

  代码中能够返回云文件ID代表图片上传成功了，但是不代表数据正确的插入到了云数据库，需要再插入云数据库的部分是否有问题。

  submit(){
      var that = this;
      wx.showLoading({title: '上传中',})// 上传图片到云存储
      let promiseArr = [];
      for(var i = 0;i<that.data.images.length;i++){
          promiseArr.push(new Promise((reslove,reject)=>{
              let item = that.data.images[i];
              let suffix = /\.\w+$/.exec(item)[0];//正则表达式，返回文件扩展名
              wx.cloud.uploadFile({
                  cloudPath: new Date().getTime() + suffix, // 上传至云端的路径
                  filePath: item, // 小程序临时文件路径
                  success: res => {// 返回文件 ID
                      console.log(res.fileID)
                      that.setData({
                          fileID: that.data.fileID.concat(res.fileID)
                      })
                      reslove();
                  },
                  fail: console.error
                  })
             }))
     }
     console.log(that.data.content, that.data.ratevalue, that.data.movieid, that.data.fileIDs)
     Promise.all(promiseArr).then(res=>{
         // 插入数据
         db.collection('comment').add({
             data:{
                 content: that.data.content,
                 score: that.data.ratevalue,
                 moviesId: that.data.movieid,
                 fileIDs: that.data.fileIDs
             }
         }).then(res=>{
             wx.hideLoading()
             wx.showToast({
                 title: '上传成功',
             })
         }).catch(err => {
             wx.hideLoading()
             wx.showToast({
                 title: '上传失败',
             })
         })
   })
  },

  跟着视频走，感觉是一样的。?
