uni.downloadFile({ url: res.downloadUrl }).then(downloadRes => {  
                            downloadRes = downloadRes[1] //而且这个回调参数居然是包含了两个元素的数组,下载结果在downloadRes[1]中, downloadRes[0]是个null??  
                            if (downloadRes.statusCode === 200) {  
                                console.log('下载成功: ', downloadRes);  
                                uni.saveFile({  
                                  tempFilePath: downloadRes.tempFilePath,  
                                  success: function (saveRes) {  
                                    console.log("保存后的文件信息：", saveRes);  
                                  }  
                                });
