多个回调查询处理程序？

Question

python-telegram-bot包装器可以使用多个回调查询处理程序吗？

我想有多个独特的处理程序，但据我所知，只能有一个。这意味着我不得不基于我在启动消息文本上显示的内联键盘。

有什么我失踪了吗？

您可以使用ConversationHandler包装器。检查代码波纹管：

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

TELEGRAM_HTTP_API_TOKEN = 'PASTE_TELEGRAM_HTTP_API_TOKEN' 

FIRST, SECOND = range(2) 

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 
    keyboard = [ 
     [InlineKeyboardButton(u"Next", callback_data=str(SECOND))] 
    ] 
    reply_markup = InlineKeyboardMarkup(keyboard) 
    bot.edit_message_text(
     chat_id=query.message.chat_id, 
     message_id=query.message.message_id, 
     text=u"First CallbackQueryHandler, Press next" 
    ) 

    reply_markup = InlineKeyboardMarkup(keyboard) 

    bot.edit_message_reply_markup(
     chat_id=query.message.chat_id, 
     message_id=query.message.message_id, 
     reply_markup=reply_markup 
    ) 
    return SECOND 

def second(bot, update): 
    query = update.callback_query 
    bot.edit_message_text(
     chat_id=query.message.chat_id, 
     message_id=query.message.message_id, 
     text=u"Second CallbackQueryHandler" 
    ) 
    return 

updater = Updater(TELEGRAM_HTTP_API_TOKEN) 

conv_handler = ConversationHandler(
    entry_points=[CommandHandler('start', start)], 
    states={ 
     FIRST: [CallbackQueryHandler(first)], 
     SECOND: [CallbackQueryHandler(second)] 
    }, 
    fallbacks=[CommandHandler('start', start)] 
) 

updater.dispatcher.add_handler(conv_handler) 

updater.start_polling() 

updater.idle()

您可以使用CallbackQueryHandler pattern参数。正则表达式模式来测试telegram.CallbackQuery.data针对。

def motd(bot, update): 
    motd_keyboard = [[InlineKeyboardButton('I agree', 
     callback_data='motd_callback_button')]] 
    motd_markup = InlineKeyboardMarkup(motd_keyboard) 
    update.message.reply_text('Message of the day', 
     reply_markup=motd_markup) 

def motd_callback_button(bot, update): 
    pass 

def main(): 
    dp = DjangoTelegramBot.dispatcher 
    dp.add_handler(CallbackQueryHandler(motd_callback_button, 
     pattern='^motd_callback_button$'))
