wx.downloadFile是报错,视频地址是http://www.iesdouyin.com/aweme/v1/play/?video_id=v0200fg10000col413jc77u6dot73i8g&ratio=1080p&line=0, 放到浏览器可以正常播放,使用这个组件时开发工具却下载了一个json文件,手机调试是直接报错的,报的就是downloadFile:fail file data is empty? downloadVideo: function() {     let that = this;     let url_video = that.data.url_video;     console.log(url_video)     if (!url_video.includes("https")){       url_video = url_video.replace("http","https")     }     let httpHost = app.globalData.httpHost;     console.log("执行了")     let task = wx.downloadFile({       url: url_video,        success(res) {         // 只要服务器有响应数据，就会把响应内容写入文件并进入 success 回调，业务需要自行判断是否下载到了想要的内容         if (res.statusCode === 200) {           wx.saveVideoToPhotosAlbum({             filePath: res.tempFilePath,             success(res) {               console.log(res.errMsg)               wx.showToast({                 title: '保存成功',               })              },             fail(res){               wx.showModal({                 title: '提示',                 content: '视频未保存成功',                 showCancel: true,                 confirmText: '确定',               })             }           })         }       },       fail(res){         console.log("错误信息:"+res.errMsg)         wx.showModal({           title: '提示',           content: res,           showCancel: true,           confirmText: '确定',         })       }     })

通过postman发送请求新增一级菜单,忘了把之前的菜单记录添加进去了,结果新增后旧的菜单记录没有了,怎么找回来啊?
