疑问描述

代码如下：

 final String msg = content.get(new SecureRandom().nextInt(content.size()));
                final String img = images.get(new SecureRandom().nextInt(images.size()));
                for (BotManager<?> manager : botManagers) {
                    if (manager instanceof MiraiBotManager miraiBotManager) {
                        MiraiBot bot = miraiBotManager.get(Identifies.ID(id));
                        assert bot != null;
                        MiraiFriend friend = bot.getFriend(Identifies.ID(qq));
                        assert friend != null;
                        friend.sendAsync(msg);
                        friend.sendAsync(img);
                        log.info("正在发送定义语录，当前qq={}, 语录={}, img={}", qq, msg, img);
                        break;
                    }
                }

不好意思，我不知道是不是我使用的方式不对，报错了，可以给个具体的实例吗？
注入的是

@Autowired
 private BotManagers botManagers;
代码如下：
                final String msg = content.get(new SecureRandom().nextInt(content.size()));
                //图片URL：https://gitee.com/xxg-git/file-services/raw/master/QQ-robot/%E5%BE%AE%E4%BF%A1%E5%9B%BE%E7%89%87_20201004212532.jpg
                final String img = images.get(new SecureRandom().nextInt(images.size()));
                Path path = Paths.get(img + "/image.jpg");
                MiraiSendOnlyImage sendOnlyImage = MiraiSendOnlyImage.of(Resource.of(path));
                for (BotManager<?> manager : botManagers) {
                    if (manager instanceof MiraiBotManager miraiBotManager) {
                        MiraiBot bot = miraiBotManager.get(Identifies.ID("2634246"));
                        // 拿到bot，怎么操作看你心情，比如往某个群发消息
                        assert bot != null;
                        MiraiFriend friend = bot.getFriend(Identifies.ID(qq));
                        assert friend != null;
                        friend.sendAsync(msg);
                        sendOnlyImage.uploadBlocking(friend);
                        log.info("正在发送定义语录，当前qq={}, 语录={}, img={}", qq, msg, img);
                        break;
                    }
                }

MiraiFriend friend = ...;

// 构建图片
MiraiSendOnlyImage offlineImage = MiraiSendOnlyImage.of(Resource.of(new URL("https://xxx.img")));

// 上传图片到friend，然后向其发送
// 得到发送回执的 Future
CompletableFuture<? extends SimbotMiraiMessageReceipt<Friend>> receipt = offlineImage.uploadAsync(friend).thenCompose(friend::sendAsync);

// do something...

感谢，成了

请问如果想转发群 A 的图文消息并处理文字后再转发到群 B 怎么实现

[ForteScarlet]

@ilemon996 如果你想说的是合并转发消息，参考 #161
