Telegram 机器人中的 CallbackQuery 问题

请使用 TelegramApiv 6.7.0，它支持 telegram API 的新功能。 阅读您的代码后，此遗嘱错误中缺少一些要点。我们应该首先检查以防止异常。if(update.getMessage()...)update.hasMessage()

无论如何，你可以查看我的代码，我按照你的结构写了。

public class InlineBot extends TelegramLongPollingBot {
    @Override
    public void onUpdateReceived(Update update) {
        if(update.hasMessage() && update.getMessage().getText().equals("/menu")){ // check hasMessage first! if not check hasMessage(), it call getMessage(), it breaks into runtimeException
            String chatId = String.valueOf(update.getMessage().getChatId());
            sendMarkup(createMenuMarkup(), chatId);
        } else if(update.hasCallbackQuery()){
            System.out.println("Callback Received");
            handleCallback(update);
        }
    }

    private void sendMarkup(InlineKeyboardMarkup menuMarkup, String chatId) {
        SendMessage sendMessage = new SendMessage();
        sendMessage.setChatId(chatId);
        sendMessage.setText("Please choose button below:"); // if not set Text message, it won't send
        sendMessage.setReplyMarkup(menuMarkup);
        try {
            execute(sendMessage);
        } catch (TelegramApiException e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public String getBotToken() {
        return "...";
    }

    @Override
    public String getBotUsername() {
        return "...";
    }

    private InlineKeyboardMarkup createMenuMarkup() {
        List<List<InlineKeyboardButton>> inlineButtons = new ArrayList<>();
        List<InlineKeyboardButton> inlineKeyboardButtonList1 = new ArrayList<>();
        List<InlineKeyboardButton> inlineKeyboardButtonList2 = new ArrayList<>();

        InlineKeyboardButton inlineKeyboardButton1 = InlineKeyboardButton.builder()
                .text("Choice 1")
                .callbackData("1")
                .url("https://www.google.com")
                .build();

        InlineKeyboardButton inlineKeyboardButton2 = InlineKeyboardButton.builder()
                .text("Choice 2")
                .callbackData("2")

        InlineKeyboardButton inlineKeyboardButton4 = InlineKeyboardButton.builder()
                .text("Choice 4")
                .callbackData("4")
                .build();


        inlineKeyboardButtonList1.add(inlineKeyboardButton1);
        inlineKeyboardButtonList1.add(inlineKeyboardButton2);

                .build();
    }

    private void handleCallback(Update update) {
        String callData = update.getCallbackQuery().getData();
        String chatId = String.valueOf(update.getCallbackQuery().getMessage().getChatId());
        System.out.println(callData);
        switch (callData) {
            case "1":
                sendMessage("You chose 1", chatId);
                break;
