Python Telegram Bot InlineKeyboard：要求用户确认

Question

用户使用内联键盘与我的 Telegram 机器人交互。 一些按钮执行敏感的功能，我想在继续之前询问用户的确认。

例如：在主菜单中，用户在两个按钮Option 1和Option 2之间进行选择。 如果单击，则分别执行敏感函数do_action_1和do_action_2 。

一个最小的工作示例如下：

from telegram import InlineKeyboardButton, InlineKeyboardMarkup, Update
from telegram.ext import Updater, CommandHandler, CallbackQueryHandler, CallbackContext


def start(update: Update, context: CallbackContext) -> None:
     update.message.reply_text('Please choose:',
                              reply_markup = keyboard_main_menu())


def main_menu(update: Update, context: CallbackContext) -> None:
    """ Displays the main menu keyboard when called. """

    query = update.callback_query
    query.answer()
    query.edit_message_text(text         = 'Please choose an option:',
                            reply_markup = keyboard_main_menu())


def keyboard_main_menu():
    """ Creates the main menu keyboard """

    keyboard = [
        [InlineKeyboardButton("Option 1", callback_data='1'),
         InlineKeyboardButton("Option 2", callback_data='2'),],
    ]

    return InlineKeyboardMarkup(keyboard)


def do_action_1(update: Update, context: CallbackContext) -> None:

    keyboard = [[InlineKeyboardButton("Main menu", callback_data='main')]]
    reply_markup = InlineKeyboardMarkup(keyboard)

    query = update.callback_query
    query.answer()
    query.edit_message_text(text=f"Selected option {query.data}\n"
                                 f"Executed action 1.",
                            reply_markup=reply_markup)


def do_action_2(update: Update, context: CallbackContext) -> None:

    keyboard = [[InlineKeyboardButton("Main menu", callback_data='main')]]
    reply_markup = InlineKeyboardMarkup(keyboard)

    query = update.callback_query
    query.answer()
    query.edit_message_text(text=f"Selected option {query.data}\n"
                                 f"Executed action 2.",
                            reply_markup=reply_markup)


def main() -> None:
    """Run the bot."""

    updater = Updater("TOKEN")

    updater.dispatcher.add_handler(CommandHandler('start', start))
    updater.dispatcher.add_handler(CallbackQueryHandler(main_menu, pattern='main'))
    updater.dispatcher.add_handler(CallbackQueryHandler(do_action_1, pattern='1'))
    updater.dispatcher.add_handler(CallbackQueryHandler(do_action_2, pattern='2'))

    # Start the Bot
    updater.start_polling()
    print('started')


if __name__ == '__main__':
    main()

现在，我想在单击Option 1或Option 2后插入一个中间步骤，显示键盘“Are you sure?” 有两个按钮Yes和No 。 单击Yes将根据用户在前一个键盘上的选择执行do_action_1或do_action_2 。 单击No将使用户返回主菜单。

我怎样才能做到这一点？

Answer 1

您可以显示带有 YES 和 NO 选项的键盘，并像处理其他按钮的输入一样处理输入。 要跟踪用户按下 YES 时要执行的操作，您可以在callback_data中对该操作进行编码或临时存储它。 另请参阅此 wiki 页面和Storing Data 。

Answer 2

感谢@CallMeStag的回答，我设法得到了一个mwe：

from telegram import InlineKeyboardButton, InlineKeyboardMarkup, Update
from telegram.ext import Updater, CommandHandler, CallbackQueryHandler, CallbackContext


def start(update: Update, context: CallbackContext) -> None:
    """Sends a message with three inline buttons attached."""

    update.message.reply_text('Please choose:',
                              reply_markup = keyboard_main_menu())


def main_menu(update: Update, context: CallbackContext) -> None:
    """ Displays the main menu keyboard when called. """

    query = update.callback_query
    query.answer()
    query.edit_message_text(text         = 'Please choose:',
                            reply_markup = keyboard_main_menu())


def keyboard_main_menu():
    """ Creates the main menu keyboard """

    keyboard = [
        [InlineKeyboardButton("Option 1", callback_data='1'),
         InlineKeyboardButton("Option 2", callback_data='2'),],
    ]

    return InlineKeyboardMarkup(keyboard)


def confirm(update: Update, context: CallbackContext) -> None:
    """Parses the CallbackQuery and updates the message text."""

    query = update.callback_query
    query.answer()

    keyboard = [
        [InlineKeyboardButton("Yes", callback_data=f'YES{query.data}'),
         InlineKeyboardButton("No",  callback_data='main'),],
    ]

    reply_markup = InlineKeyboardMarkup(keyboard)

    query.edit_message_text(text=f"Selected option {query.data}."
                                 f"Are you sure ? ",
                            reply_markup=reply_markup)


def do_action_1(update: Update, context: CallbackContext) -> None:

    keyboard = [[InlineKeyboardButton("Main menu", callback_data='main')]]
    reply_markup = InlineKeyboardMarkup(keyboard)

    query = update.callback_query
    query.answer()
    query.edit_message_text(text=f"Selected option {query.data}\n"
                                 f"Executed action 1.",
                            reply_markup=reply_markup)


def do_action_2(update: Update, context: CallbackContext) -> None:

    keyboard = [[InlineKeyboardButton("Main menu", callback_data='main')]]
    reply_markup = InlineKeyboardMarkup(keyboard)

    query = update.callback_query
    query.answer()
    query.edit_message_text(text=f"Selected option {query.data}\n"
                                 f"Executed action 2.",
                            reply_markup=reply_markup)


def main() -> None:
    """Run the bot."""
    # Create the Updater and pass it your bot's token.
    updater = Updater("TOKEN")

    updater.dispatcher.add_handler(CommandHandler('start', start))
    updater.dispatcher.add_handler(CallbackQueryHandler(main_menu, pattern='main'))
    updater.dispatcher.add_handler(CallbackQueryHandler(confirm, pattern='^(|1|2)$'))
    updater.dispatcher.add_handler(CallbackQueryHandler(do_action_1, pattern='YES1'))
    updater.dispatcher.add_handler(CallbackQueryHandler(do_action_2, pattern='YES2'))


    # Start the Bot
    updater.start_polling()
    print('started')

if __name__ == '__main__':
    main()

现在，机器人在执行do_action_1和do_action_2之前正确地要求用户确认。 非常感谢 ！
