			ToastUtil.showTipToast(`前往手机设置-应用打开${getHostName_()}相册权限`)
		} else if (err.errNo != 10502 && 'chooseVideo:fail cancel' != err.errMsg) {
			ToastUtil.showTipToast("获取上传文件异常:" + JSON.stringify(err))
		} 
	},

		if (res && res.tempFilePath && res.duration >= 3 && res.size <= 500*1024*1024) {
			page.uploadFile = res.tempFilePath
