Question

我是Telegram机器人api的新手，正在尝试使用嵌入式键盘制作一个简单的bot。我的机器人运行正常，但在选择了最终的嵌入式键盘选项后无法发送回消息。这是我的代码：

import telegram
from telegram.ext import Updater,CommandHandler,MessageHandler,Filters,CallbackQueryHandler
from telegram import InlineKeyboardButton,InlineKeyboardMarkup,KeyboardButton,ReplyKeyboardMarkup
def start(bot, update):
    bot.send_message(chat_id=update.message.chat_id, text='Hi, I am Food Bot')
    update.message.reply_text(main_menu_message(),
                            reply_markup=main_menu_keyboard())

def main_menu(bot, update):
  query = update.callback_query
  bot.edit_message_text(chat_id=query.message.chat_id,
                        message_id=query.message.message_id,
                        text=main_menu_message(),
                        reply_markup=main_menu_keyboard())

def first_menu(bot, update):
  query = update.callback_query
  bot.edit_message_text(chat_id=query.message.chat_id,
                        message_id=query.message.message_id,
                        text=first_menu_message(),
                        reply_markup=first_menu_keyboard())

def second_menu(bot, update):
  query = update.callback_query
  bot.edit_message_text(chat_id=query.message.chat_id,
                        message_id=query.message.message_id,
                        text=second_menu_message(),
                        reply_markup=second_menu_keyboard())
def main_menu_keyboard():
  keyboard = [[InlineKeyboardButton('Breakfast', callback_data='op1')],
                 [InlineKeyboardButton('Lunch or Dinner', callback_data='op2')]]
  return InlineKeyboardMarkup(keyboard)

def first_menu_keyboard():
  keyboard = [[InlineKeyboardButton('Omelette and 2 Bread slices with coffee',callback_data = 'b1')],
                     [InlineKeyboardButton('Aloo paratha with curd and tea',callback_data = 'b2')],
                     [InlineKeyboardButton('Masala dosa with sambar and chutney with coffee',callback_data = 'b3')]]
  return InlineKeyboardMarkup(keyboard)

def second_menu_keyboard():
  keyboard = [[InlineKeyboardButton('Paneer Makhni with 2 rotis and rice',callback_data = 'l1')],
                     [InlineKeyboardButton('Pasta in white sauce with 2 pieces of garlic bread',callback_data = 'l2')],
                     [InlineKeyboardButton('Biryani with raita',callback_data = 'l3')]]
  return InlineKeyboardMarkup(keyboard)
def main_menu_message():
  return 'What do you want to order?'

def first_menu_message():
  return 'Choose the food option:'

def second_menu_message():
  return 'Choose the food option:'
def breakfast1(bot,update):
    bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Your order: Omelette and 2 Bread slices with coffee')
def breakfast2(bot,update):
    bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Your order: Aloo paratha with curd and tea')
def breakfast3(bot,update):
    bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Your order: Masala dosa with sambar and chutney with coffee')

def lunchdinner1(bot,update):
        bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Your order: Paneer Makhni with 2 rotis and rice')
def lunchdinner2(bot,update):
        bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Your order: Pasta in white sauce with 2 pieces of garlic bread')
def lunchdinner3(bot,update):
        bot.send_message(chat_id=update.message.chat_id,
                        message_id=update.message.message_id,
                        text='Biryani with raita')
def main():
    bot=telegram.Bot(token=TOKEN)
    updater = Updater(token=TOKEN)

    updater.dispatcher.add_handler(CommandHandler('start', start))
    updater.dispatcher.add_handler(CallbackQueryHandler(main_menu, pattern='main'))
    updater.dispatcher.add_handler(CallbackQueryHandler(first_menu, pattern='op1'))
    updater.dispatcher.add_handler(CallbackQueryHandler(second_menu, pattern='op2'))
    updater.dispatcher.add_handler(CallbackQueryHandler(breakfast1,
                                                        pattern='b1'))
    updater.dispatcher.add_handler(CallbackQueryHandler(breakfast2,
                                                        pattern='b2'))
    updater.dispatcher.add_handler(CallbackQueryHandler(breakfast3,
                                                        pattern='b3'))
    updater.dispatcher.add_handler(CallbackQueryHandler(lunchdinner1,
                                                        pattern='l1'))
    updater.dispatcher.add_handler(CallbackQueryHandler(lunchdinner2,
                                                        pattern='l2'))
    updater.dispatcher.add_handler(CallbackQueryHandler(lunchdinner3,
                                                        pattern='l3'))


    updater.start_polling()
if __name__ == '__main__':
    main()

在选择主菜单中的一个选项时，相应地出现下一个菜单，但是当从第二个菜单中选择了该选项时，即使我为这些选项的回调数据添加了处理程序，也没有任何反应，并且函数必须发送消息。我究竟做错了什么？

我建议read此代码，并使用ConversationHandler代替它。您只需要使用户返回特定状态，然后等待命令，消息或回调，然后获取更新，并在检测到用户操作后执行您的工作即可。

当您启动更新程序时，您也不必启动Bot。更新程序对象同时传递两个漫游器，并在获得用户输入时更新您的功能。

电报Bot回复键盘后无法发送消息
