shareFileMessage使用过程中出现概率性有用，大概率性失效的问题。真机仿真结果如图[图片] 代码如下： dataRowClick: function (e, id){         var model = products_url[id-1].model;         var statue = "已发布";         if (products_url[id-1].url == 'null'){           statue = "在研"         }         console.log(e);         console.log(statue)         var products_head_url ='cloud://cloud1-7gvpe9lfc973e8bc.636c-cloud1-7gvpe9lfc973e8bc-1316841949/CAD/';                  let fileID = products_head_url+model+'.dwg';         console.log(fileID); // 打印文件链接         if(statue == "在研"){           wx.showToast({             title: '未发布',             duration:2000,           });           return;         }         wx.showLoading({           title:'下载中',           duration:1000         });         wx.cloud.downloadFile({           fileID: fileID, // 使用文件链接             success: function (res) {             var fileName = fileID.split('/').pop()             // wx.saveFile({             //   tempFilePath: res.tempFilePath,             //   filePath: wx.env.USER_DATA_PATH + '/' + fileName,                            //   success: function (res) {             //     wx.showToast({             //       title: '下载成功',             //       icon:'success',             //       duration:2000             //     })                              //   }                            // })             wx.shareFileMessage({               filePath: res.tempFilePath,               // filePath: wx.env.USER_DATA_PATH + '/' + fileName,                              success(data) {                 console.log('转发成功！！！',data)               },               fileName:fileName,               fail: console.error,             })           }         })       }, dataRowClick绑定在表格的一行点击事件，用  <view id='{{item[keyName].val}}' style="width:{{dataAreaWidth}}px;height:{{rowHeight}}px;" bindtap="dataRowClick">
