如何发送本地图片？

yuhanzero

新人，仿照非官方帮助文档的图片部分写法，文字发送成功了，图片没有发送，但是日志上面显示发送了。问题和这类似，按照大佬的解答没能解决，希望得到帮助。
代码：

        this.globalEventChannel().subscribeAlways<GroupMessageEvent> { event ->
            if (message.contentToString() == "#tx") {
                var contact = event.group
                var ex = File("D:\\tx.jpg").toExternalResource("jpg")
                var img = contact.uploadImage(ex)
                ex.close()

                contact.sendMessage(img)
                contact.sendMessage("tx")
            }
        }
