JDA Discord 添加对消息的反应

Question

我在尝试对机器人发送的消息添加反应时遇到问题。这是我的代码和我在尝试添加反应时遇到的问题。

这个想法很简单。只是机器人发送的民意调查命令 + 对其添加反应，例如竖起大拇指和竖起大拇指：

“$poll This Is Example Poll”，创建此投票后，添加反应

代码 -

    @Override
    protected void execute(CommandEvent event) {
        if (this.check(event)) {
            return;
        }

        var args = event.getArgs().trim();
        if (args.isEmpty()) {
            this.incorrectUsage(event);
            return;
        }

        var announcementFormat = this.getConfig().getMessages().get("pool-format")
                .replaceAll("%message", args);


        event.reply(announcementFormat);
        event.getMessage().addReaction("✔").queue();
    }

错误 -

Answer 1

您可以使用 flatMap:

event.getChannel().sendMessage(announcementFormat)
     .flatMap(message -> message.addReaction("✔"))
     .queue();

而不是event.reply(announcementFormat)。

您的代码当前尝试向用户发送的消息添加反应，而不是您的机器人发送的消息。但是，该消息当时已被删除，这就是您收到 Unknown Message 错误的原因。
