如何处理 python 电报机器人中的回调查询

How to handle callbackquery in python telegram bot

在我的代码中,我遇到了回调查询处理程序的问题,当我点击 /start 命令时,会出现“Next”按钮,当我点击该按钮时,它会给我提示回复为“hi”,直到此处输出正确。然后当我点击另一个命令“/help”然后出现“help”按钮时,当我点击那个帮助按钮时它会给我之前的回复是 "hi",输出应该是“help

 from telegram import InlineKeyboardButton, InlineKeyboardMarkup
 from telegram.ext import Updater, CommandHandler, CallbackQueryHandler, ConversationHandler

 TELEGRAM_HTTP_API_TOKEN = 'token'

 FIRST, SECOND, HELP = range(3)

 def start(bot, update):
        keyboard = [
            [InlineKeyboardButton(u"Next", callback_data=str(FIRST))]
        ]
        reply_markup = InlineKeyboardMarkup(keyboard)
        update.message.reply_text(
            u"Start handler, Press next",
            reply_markup=reply_markup
        )
        return FIRST

 def first(bot, update):
        query = update.callback_query
        #reply_markup = InlineKeyboardMarkup(keyboard)
        bot.send_message(chat_id=query.message.chat_id,
                         text='hi')

 def help(bot,update):
        keyboard = [
            [InlineKeyboardButton(u"HELP", callback_data=str(HELP))]
        ]
        reply_markup = InlineKeyboardMarkup(keyboard)
        update.message.reply_text(
            u"Help handler, Press button",
            reply_markup=reply_markup
        )

        return HELP

 def myhelp(bot,update):
        query = update.callback_query
        bot.send_message(chat_id=query.message.chat_id,
                         text='help')

 updater = Updater(TELEGRAM_HTTP_API_TOKEN)

 conv_handler = ConversationHandler(
        entry_points=[CommandHandler('start', start)],
        states={
            FIRST: [CallbackQueryHandler(first)]
        },
        fallbacks=[CommandHandler('start', start)]
    )
 conv_handler1=ConversationHandler(
        entry_points=[CommandHandler('help',help)],
        states={
            HELP: [CallbackQueryHandler(myhelp)]
        },
        fallbacks=[CommandHandler('help',help)]
    )

 updater.dispatcher.add_handler(conv_handler)
 updater.dispatcher.add_handler(conv_handler1)

 updater.start_polling()

 updater.idle()

您是第一个会话处理程序,仍处于 FIRST 状态,因此仍在等待回调查询。 因为它是第一个添加的处理程序并且它们在同一组中,所以第一个会响应,而第二个不会。 您可以查看 CallbackQueryHandlerpattern 参数来解决您的问题。

似乎使用 return ConversationHandler.END 结束对话也可以,因为它会结束第一个对话。 请参阅此处的示例:https://github.com/python-telegram-bot/python-telegram-bot/blob/master/examples/conversationbot.py
