#Discord JDA #clear/purge 命令，为什么我的清除以前消息的代码没有按预期工作？

Question

我是 Discord JDA 的新手 API，我被这个问题困住了。每当我运行这段用于“清除”命令的代码时，机器人只显示 error1 消息。即使我在 !purge 后面加上“!purge 23”之类的数字，机器人也没有响应。我究竟做错了什么？我多年来一直坚持这一点。任何帮助将不胜感激！

public void onMessageReceived(MessageReceivedEvent event) {
    String[] args = event.getMessage().getContentRaw().split("//s+");
    if(args[0].equalsIgnoreCase(Bot.prefix + "purge")) {
        if (args.length < 2) {
            EmbedBuilder error1 = new EmbedBuilder();
            error1.setColor(Color.RED);
            error1.setTitle("❌ Specify # of messages to delete!");
            error1.setDescription("Usage: " + Bot.prefix + "purge [# of messages]");
            event.getChannel().sendTyping().queue();
            event.getChannel().sendMessage(error1.build()).queue(m -> 
            m.delete().queueAfter(5, TimeUnit.SECONDS));
        }
        
        else if(Integer.parseInt(args[1]) > 100 || Integer.parseInt(args[1]) < 1) {
            EmbedBuilder error2 = new EmbedBuilder();
            error2.setColor(Color.RED);
            error2.setTitle("❌ Only 1-100 messages can be deleted!");
            error2.setDescription("Usage: " + Bot.prefix + "clear [1-100]");
            event.getChannel().sendMessage(error2.build()).queue(m -> 
            m.delete().queueAfter(5, TimeUnit.SECONDS));
        }
        
        else if(Integer.parseInt(args[1]) < 100 && Integer.parseInt(args[1]) > 1){
            int values = Integer.parseInt(args[1]);
            event.getMessage().delete();
            List<Message> messages = event.getChannel().getHistory().retrievePast(values).complete();
            event.getTextChannel().deleteMessages(messages).queue();
            event.getChannel().sendMessage("✅ " + args[1].toString() + " messages 
            deleted!").queue(m -> 
            m.delete().queueAfter(5, TimeUnit.SECONDS));
        }
    }
}

}

你的拆分正则表达式是错误的。你做了 "//s+" 但你应该做 "\s+".
